Publisher: 2012Dissertation note: Background
Nosocomial infection is a worldwide problem causing high number of deaths. The major causative agent of infection is methicillin resistant Staphylococs aureus (MRSA). Surgical site infections in orthopedic surgery (SSIS) are mainly (48%) caused by Staph. aureus, out of which 68% are MRSA and causes a number of deaths annually.
Hypothesis
As medicinal plants like (Opuntia delinii, Acacia nilotica and Alo vera) have the anti bacterial activity, So these plants may be effective against methicillin resistant Staphylococs aureus (MRSA) And antibiotic like (Moxifloxacillin, Cefipime and Imipenem/Cilastatin and Ampicillin+Cloxacillin) selected in this study have antibacterial activity against gram positive bacteria so may these have effectiveness against methicillin resistant Staphylococs aureus (MRSA).
Material and method
In this study MRSA isolated from the post operative wounds of one hundred hospitalized patients from three hospitals (Mayo Hospital, Services Institute of Medical Sciences and Jinnah Hospital) of Lahore. The isolates obtained from the wound identified as MRSA by cultural and biochemical characteristics. Methicillin resistant Staphylococs aureus strains are resistant to many antibiotics even vancomycin. In the present study the efficacy of three medicinal plants (Opuntia delinii, Acacia nilotica and Alo vera) studied against MRSA using extracts of the plants. The extracts also further used to determine MICs against methicillin resistant Staphylococs aureus isolated strains. MICs of four antibiotics and their combinations commonly used for treatment of post operative wounds like Moxifloxacin, Cefipime, Imipenem/Cilastatin and Ampicillin+Cloxacillin determined using Linezolid and Vancomycin as standards by micro dilution method in vitro.
Statistical Design
The data collected analyzed using SPSS version13.0X soft ware.
Outcome
The prevalence of MRSA found in different hospitals as under 72.5% in case of Mayo, 63.33% in case of Services Hospital and 66.66% in case of Jinnah hospital Lahore. The highest percentage found in Mayo hospital and lowest was observed in case of services hospital.
MIC results found in this study indicate that Acacia nilotica and Alo vera contain antibacterial agents which showed the good results against MRSA while Opuntia dileinii showed not promising results against MRSA and high MICs found put a question mark on its efficacy. Average MICs found in case of acacia leaves and bark are as 84 (µg)/ml and 62.5 (µg)/ml respectively. Average MIC observed in case of Aloe vera is 32.25 (µg)/ml. The highest MIC value calculated in case of Opuntia dillenii is 1228 (µg)/ml.
Antibiotics like Moxifloxacin and Imipenem/Cilastatin showed the good results and the average MICs value found 2.681 And 2.85 respectively closely resembles to the MICs of stander drugs e.i vancomycin and linezolid caluculated as 1.61 and 2.43. Cefipime showed the less activity against MRSA with the average MIC 57.81.The synergistic effects of Ampicillin+Cloxacillin was not so good as compared to the stander drugs and combination of ampicillin and cloxacillin exhibit the average MIC as 11.87.
The lowest MIC in of plants extracts observed in case of Aloe vera and highest found in case of Opuntia dillenii.

Publisher: 2012Dissertation note: Chondroitin sulphate (CS) and Glucosamine sulphate (GS) are two main components of articular cartilage. It is believed that these molecules slow down wear and tear of cartilage. Moreover, if administered exogenously as drugs, these may initiate synthesizing capacity of cartilage. Among these, GS promotes the formation and repair of cartilage, whereas CS promotes elasticity and prevent cartilage breakdown by inhibiting degradative enzymes. Concurrent use of both structural units of cartilage as drugs in osteoarthritis (OA) may lessen the progression of disease.
The present study was conducted to elucidate the chicken keel cartilage as an alternate and potential source for this endogenous component that may be used exogenously to repair or prevent damage to joints. Chicken keel cartilages were collected from healthy broilers. CS was extracted using MgCl2 solution (3M), dialyzed and digested with papain. The extracted material was purified by ethanol precipitation, centrifugation and then freeze dried. Proximate analysis of semi-purified polysaccharides revealed the presence of carbohydrates (65.49±0.10), crude protein (12.82±0.26), ash (11.12±.56), moisture (9.88±0.32) and fat (0.69±0.14). Fiber contents were found to be nil in the processed samples. Dimethylmethylene blue binding (DMMB) assay was performed for determination of percent contents of CS in extracted semi-purified samples and mean concentration was found to be 70.77±2.35. Semi-purified polysaccharides were further characterized by FTIR (Fourier Transform Infrared Spectrometer) technique and characteristic Peaks of CS molecules were recorded at 854, 854 and 853 cm-1 and then compared with spectrum of standard CS. Protein content being a major impurity in extracted samples was determined by Bradford method quantitatively (4.64±0.29). Two protein impurities having 77.8 and 50.5 kDa molecular weights were revealed by SDS-PAGE.
Efficacy of semi-purified CS from chicken keel cartilage, standard CS from shark source and GS, alone and in combination in experimental OA rat model was evaluated. To develop OA similar to spontaneous OA, 10mg papain/0.5mL (Sigma, Cat # P 3125) in buffered solution of 0.05 M sodium acetate pH 4.5 was injected intra-articularly in each right knee joint of fifty five albino rats (pre-anesthetized with anesthetic ether). Ten rats (n= 10) were injected with 0.5mL of normal saline (0.9%) in right knee joint that served as control group. Then from fifty five papain injected rats, twenty five were divided into five groups (n=5) for development and assessment of OA model (OA groups). Progression of disease was monitored by clinical scores, histopathological scores and concentration of CTX-II as biomarker in sera samples of experimental rats by ELISA using a commercial kit (serum preclinical CartiLaps ® ELISA kit) for control and OA groups (n=5) on day 0 (control group) and days 1st, 7th, 14th, 21st and 28th post papain injection (OA groups). Highest mean clinical score (10.38±1.1) was observed on 1st day and least on 28th day post papain injection i.e. 5.00±.34. Highest mean histopathological score and CTX-II concentration was recorded on 28th day i.e. 12.82±1.64 and 36.82±3.81. Values of clinical scores, histopathological scores and CTX-II concentration reached to maximum on 21st day and then sustained thereon. Second phase of experiment is comprised of evaluating and comparing the efficacy of extracted CS samples (chicken keel cartilages), standard CS (shark source) alone and in combination with GS. For this purpose, remaining five rats out of ten injected with normal saline intra-articularly served as control groups along with treated and non treated groups of experimental rats. Remaining thirty OA induced rats were divided into six groups (five rats /group). Group 1 (n=5) called non treated group received only placebo till 60th day and served as negative control group.
Treated Group 2 received GS alone, Group 3 CS (standard) and Group 4 were given extracted CS. Group 5 was treated with combination of GS plus CS (standard) and Group 6 with GS plus CS (sample). Doses of glycosaminoglycans (GAGs) were administered as 1.2g/kg/day CS and 1.5g/kg/day GS alone and in combinations. Drugs were offered early in the morning in bolus form with feed (10g) after overnight fasting while non-treated group received only placebo (without any drug).
Anti-arthritis activities of CS standard and extracted alone and in combination with GS were assessed clinically, analyzed statistically by using one way ANOVA. Level of significance (P<0.05) was recorded by using Duncan's Multiple Range (DMR) Post hoc Test. Mean scores of clinical, histopathology and CTX-II concentrations observed at 60th day in control rats (without OA) were 0.00, 0.00 and 2.55, respectively. OA induced untreated group showed mean score for clinical signs, histopathological scores and CTX-II concentrations 4.15, 12.24 and 36.70 and GS treated group 3.19, 3.96 and 6.12 at 60th day of treatment, respectively. For CS (standard), mean scores of clinical signs, histopathological lesions and CTX-II concentrations were recorded as 2.64, 2.44 and 4.48 and for CS (extracted) were 2.26, 2.28 and 4.40 in sera correspondingly at 60th day of treatment. The lowest mean values of clinical signs, histopathology and CTX-II concentrations in sera of treated group with standard CS plus GS were found to be 0.94, 0.94 and 2.62 followed by extracted CS plus GS treated groups 01.05, 1.27 and 2.74, respectively. Clinical, histopathological scores and CTX-II concentrations in group of rats treated with combinations were found to reverse the diseased condition after 60th days of treatment as the values were close to that of normal rats and far away from OA rats. It is concluded that extracted CS from poultry has comparable efficacy with CS standard from shark source alone and in combination with GS. Poultry by-product (keel cartilage) is found to be an alternate and cheap source for CS (chondroprotective agent) as compare to expensive, less available and religiously prohibited source for Islamic countries particularly.

Publisher: 2013Dissertation note: Piroxicam and Meloxicam are enolic acid derivatives and belong to oxicam class of non steroidal anti-inflammatory drugs. They are therapeutically used in rheumatoid arthritis and osteoarthritis. This study was designed to evaluate mutagenicity and cytotoxicity of piroxicam and meloxicam by Ames Salmonella/microsome mutagenicity assay and MTT assay. In this study, ten concentrations (100µg/ml, 300µg/ml, 500µg/ml, 700µg/ml, 900µg/ml, 1000µg/ml, 3000µg/ml, 5000µg/ml, 7000µg/ml and 10,000µg/ml) of piroxicam and meloxicam were used in Ames test against Salmonella strain TA100 in plate incorporation method, with and without metabolic activation S-9 mixture in triplicate manner. In MTT assay, confluent monolayer of BHK-21 cell lines was used and grown in 96-well cell culture plates treated with same concentrations of both drugs in triplicate manner. The results indicated that piroxicam had no mutagenic potential at concentrations of 100µg/plate to 3000µg/plate, possible mutagenic potential at 5000µg/plate and significant mutagenic potential at concentration of 7000µg/plate and 10,000µg/plate. Meloxicam had no mutagenic potential at the concentrations 100µg/plate to 7000µg/plate and possible mutagenic potential at highest concentration 10,000µg/plate. The cytotoxic effect of piroxicam and meloxicam at the concentrations of 100µg/ml to 5000µg/ml was none cytotoxic and at the concentration of 7000µg/ml and 10,000µg/ml cytotoxic to BHK-21 cell lines. There was significant increased in mutant frequency with increased in concentration of both drugs with and without metabolic activation S-9 mixture. There was significant difference in non mutagenic, possible mutagenic and significant mutagenic potential doses of piroxicam. There was no significant difference in none cytotoxic doses of both drugs. In comparison of both drugs, there was no significant difference in mutagenicity and cytotoxicity. It concluded that piroxicam and meloxicam were not mutagenic and cytotoxic at therapeutic doses. Piroxicam had mutagenic potential in dose dependent manner. Both drugs were cytotoxic at higher concentrations. They had same cytotoxic effect in dose dependent manner.

Publisher: 2013Dissertation note: In vitro study was carried out in order to estimate the anti-theileria effect of Calotropis procera and Peganum harmala. Water and chloroform extracts of each plant were used in-vitro study along with standard drug Buparvaqoune (Butalex®). For this four concentrations i.e.4, 8, 12 and 16mg/ tested solutions of each extracts of each plant were applied on cultured lymphocytes exposed to theileria parasite infection. ELISA reader findings showed that the mean OD were found less in treated theileria infected lymphocytes cell culture as compared to untreated culture wells mean OD values. The highest cell reduction (94.36%) with C. procera chloroform extract treatment was observed at a concentration of 16 mg/ml solution. Lowest concentration (1mg/ml solution) of C. procera chloroform extract reduced non-significant (P>0.05) lymphocytes cell proliferation (40.97%) as compare to control negative group. P. harmala water extract was effective against the theileria parasite as significantly lower (P<0.05) mean OD value (1.802 ±0.341) was measured at a concentration of 4mg/ml solution and maximum inhibitory effect (92.20) was seen at a concentration of 16 mg/ml solution. ELISA reader findings showed that P. harmala chloroform extract treatment failed to inhibit lymphocytes cells propagation even at highest concentration. The highest inhibitory effect (85.33%) against theileria infected lymphocytes propagation was seen at a concentration of 16 mg/ml solution.
Plant extract was evaluated in respect of feed intake in rabbits. It showed that when administered extracts of C. procera in rabbits at dose of 3 mg and 5 mg/kg body weight, did not affect on feed intake in rabbits. However the chloroform and water extracts of both plant i.e. C. procera and P. harmala when were administered in rabbits parentally at dose 10 of mg/kg body. It showed that the feed intake of rabbits was non-significantly reduced as compared to other treatments groups. Hematological parameters such as WBC X103 count, RBC X 106 count and Hb g/dl values were measured at various days. Findings showed that significantly lesser RBC X 106 count was in group A3 and D3 than control at day 30 of experiment. A non-significant difference (P>0.05) was seen in RBC X 106 count and Hb g/dl measurements in all treatments groups. Kidney and liver functions were evaluated by measuring biochemical parameters, uric acid, creatinine and ALT at 0 days, 9 days and 30 days. Findings showed that serum creatinine and urea enzyme levels were significantly higher (P<0.05) in group A3 as compare to control group at day 30 of experiment. Serum level of urea was also significantly higher (P<0.05) in group B3 and D3 at day 30 of experiment. A non-significant difference (P>0.05) was seen in ALT in all treatment groups at day 30 than control. Post-mortem was performed at day 30 of experiment. Gross lesions consisting of hemorrhages, congestion, and lung emphysema were seen in rabbits treated with high dose i.e. 10 mg/kg of both extract of C. procera. Rabbits treated with P. harmala chloroform extract at dose 10 mg/kg showed moderate gross lesions. Histopathology of organs such as lungs, kidney, liver and heart was performed. Toxicity lesions were seen in rabbits treated with high dose i.e. 10 mg/kg of both extract of C. procera. Rabbits treated with P. harmala chloroform extract at dose 10 mg/kg showed histopathological lesions in lungs, liver and kidney.
Theileria infection was studied in vivo by developing through theileria infected Hayalomma ticks in crossbred calves (n=30) through. At day 15 of infection maximum increase in mean rectal temperature (105.24 ± 0.46F) was observed, twenty four calves had pyrexia (104.1- 105.6 F) and six claves were showing pyrexia > 105.6 F. A significant increase (P<0.05) in pre-scapular lymph node enlargement score of challenged calves was seen by day 7 of infection and maximum lymph node score (grossly enlarged size) was noticed in twenty calves (Table 4.14 , Plate 4.16) with peak mean score (2.73±0.44) on day 13 of infection. The piroplasm peak score (3.80±0.83) was observed in challenged calves at 22 day of infection and remained significantly higher (p<0.05) (2.60±0.54) in untreated calves until the 36 day of infection (Fig.4.29 and Table 4.16). A significant increase (P<0.05) in mean schizonts was observed in pre-scapular lymph node biopsy smear from day 7 of infection to onwards. Blood samples of challenged calves (n =30) were confirmed theileria positive through PCR test. The amplification of Theileria species were amplified at 1098 bp (Plate 4.20 and Theileria annulata was amplified at 721 bp (Plate 4.21).
In order to estimate the pattern of disease severity, severity score was measured by summation of mean score of piroplasms, schizonts, lymph node swelling and rectal temperature. From day 7, mild response (3-5 score) was seen in infected calves (n=10).
With increase in the severity of disease a significant decrease (P<0.05) was observed in mean values of the Hb g/dL amount, WBC and RBC count, Hct (%) concentration and lymphocytes percentage from day15 of infection onward to 36 day of infection. A non-significant decrease (P>0.05) in the mean values of MCH pg was seen throughout the experiment. A significant decrease (P<0.05) in mean values of MCHC g/dL along with significant increase (P<0.05) in the mean measurement of MCV fL (64.14±3.53) values was seen at day 36 of infection as compare to day 0 values, indicating macrocytic hypochromic anemia in challenged calves. These findings showed a significant increase (P<0.05) in excretory products (uric acid and creatinine) from day 15 of infection and onward as compared to day 0 values, indicating damaged kidney in infected calves. Biochemical analysis showed the significant increase (P<0.05) in liver enzymes (ALT, AST) from day 15 infection and onward.
Anti-Theileria activities of drugs were estimated by evaluating clinical manifestation of the disease and parasitological findings. Beside this treatment effect on hematological and biochemical reactions of liver and kidney functions was determined. A significant difference (P<0.05) in rectal temperature of calves groups (B and E) was observed than control positive (group F) at day 21 of post-treatment. On other hand calves treated with treatments A, C and D had a non-significant difference (P>0.05) in rectal temperature compared with untreated calves (group F). It was found that calves (n=5) dosed with C. procera chloroform extract (group A) had rectal temperature in normal range by the day 7 of post-treatment. Similarly calves (n=5) treated with Butalex were found with normal rectal temperature from the day 7 of pos-treatment. On other hand, at day 21 of treatment 40%, 20%, 40% and 80% calves were found with pyrexia in treatments groups B, C, D and F, respectively (Table 4. 46).
By the day 14 of treatment, calves of treatment groups B and E showed no parasitemia (piroplams ?1). Disease severity was estimated on accumulative score of rectal temperature, lymph node swelling and parasitological findings (piroplasms and schizonts score). It was found a significant decrease (P<0.05) occurred in the disease severity of score of disease in calves of groups B and E as compare to A, C and F at day 3 of post-treatment. At day 21 of treatment all treated calves were recovered from anemia.

Publisher: 2013Dissertation note: In the present study in vivo anti-inflammatory assay, central analgesic assay and
peripheral analgesic estimation of methanolic extract of Thuja orientalis was performed by
using carrageenan induced paw oedema model, hotplate test and acetic acid induced writhing
test on albino rats, respectively. For anti-inflammatory assay, the experimental animals were
divided into five groups each consisting of six animals and three groups of six animals were
arranged each for central and peripheral analgesic evaluation. In all groups of animals in antiinflammatory
assay, oedema was produced by using 0.1 ml of 1% carrageenan. The group II
served as standard control group and was additionally treated with 10mg/Kg p.o indomethacin
(a standard drug). The Groups III, IV and V received 50, 100 and 300 mg/Kg p.o of aqueous
methanolic extract of Thuja orientalis (TO-Cr) respectively. All the treatment groups (II, III, IV
and V) were treated 1 hour before injection of carrageenan. The volume of paw of rats was
measured at 0 h and 3 h and the results of all treatment groups were compared with group I. In
the present work, central analgesic study was done by using hot plate method. Tramadol was
used as the standard drug in positive control group. Peripheral analgesia was determined by
acetic induced writhing test using aspirin as standard analgesic drug. In the writhing test 1 %
solution of acetic acid at dose of 0.1 ml / 10 grams was injected intra peritoneal. All the groups
were pre treated 30 min before chemical stimulus with the standard drug and extract dose.
Number of writhings was counted for 20 min. after injection. The statistical analysis of these
values showed that results at 0 hour are non significant as P > 0.05 (Table 3).But it is evaluated
from the study of paw volumes after 3 hours that there was significant decrease in oedema in
group treated with standard drug i.e. indomethacin (79.70 % decrease) as compared with the
60
negative control (Fig. 11). The response of the extract under study was dose related. There was
13 % decrease in paw oedema as compared with negative control at 50 mg / kg dose of TO-Cr
(Table 7). Similarly there was 34 % and 59.57 % decrease in paw oedema as compared with
negative control at 100 mg / kg and 300 mg / kg doses of TO-Cr (Table 7). In central analgesic
model of hotplate, there was significant increase in latency time in treatment group at 60 min
interval (Table 15) and then it remained almost same after 90 min (Table 18). In peripheral
analgesia of acetic acid induced writhing test, there was significant decrease in the number of
writhings in positive control (7.33+1.63) and Thuja orientalis extract (12.50+2.35) also
decreased the number of writhings significantly as compared with the negative control group
(20.67+2.16) (Table 22).
It is concluded from the results that aqueous methanolic extract of the fruit of Thuja
orientalis has significant anti-inflammatory activity and produced dose dependant reduction in
inflammation and it also has both central and peripheral analgesic properties.

Publisher: 2013Dissertation note: In the present study, the immunomodulatory activity of meloxicam was evaluated. For the evaluation of effect of meloxicam on cellular immunity the delayed type hypersensitivity assay (DTH) and cyclophosphamide induced neutropenia assay were performed while for humoral immunity haemagglutination assay and mice lethality test was performed. In each assay 15 mice were used, all mice were divided into 3 groups, each group was consist of 5 mice. Two groups were treated with two different doses of meloxicam (5mg/kg and 10 mg/kg) and the one group (control group) was only being administered with dimethylsulphoxide (DMSO) intraperitoneally.
In DTH assay, 5mg/kg and 10mg/kg meloxicam treated groups of mice showed a significant reduction in skin thickness ( P<0.05) as compared to control group at 24hours, 48 hours and 72 hours after the challenging dose of dinitrochlorobenzene (DNCB).
In cyclophosphamide induced neutropenia assay meloxicam at 10mg/kg showed a significant percentage of reduction in total leukocytes (TLC) and two types of differential leukocytes (DLC i.e lymphocytes, and neutrophils except monocytes). This significant reduction was less in 5mg/kg meloxicam treated group which in turn was less than the control group. In addition, it was observed a dose dependent reduction response in haemagglutination (HA) titre. The order of reduction in HA titre was 10mg/kg meloxicam treated group > 5mg/kg meloxicam treated group > the control group. The mortality ratio of mice in the control group, 5mg/kg meloxicam and 10 mg/kg meloxicam treated groups was 20%, 80% and 100% respectively.
All the results of present study suggest that meloxicam has suppressive effect on cellular as well as on humoral component of immune system.

Publisher: 2013Dissertation note: At the time of collection of samples Temperature, Dissolved Oxygen, Total Dissolved Solids (TDS), Conductivity and pH were determined (YSI Digital meters) of selected sites for any possible relationship between water quality parameters, heavy metal concentrations and their effects on fish body. Fish from the selected water bodies was blotted dry and then weighed individually. After wet digestion of the sampled fish, the volume was prepared for the determination of heavy metals viz. chromium, copper, cadmium, lead, nickel and manganese. Samples for histological studies were collected on monthly basis. Slides were prepared. The results of this study provided valuable information on the metal contents in fish from different sampling stations. Fish from Balloki Headworks exhibited the highest tendency of accumulation of cadmium, lead and chromium in liver and intestine while it was the minimum in fish collected from controlled fish ponds from Ravi Campus Pattoki. Accumulation of these metals was, however, the minimum in fish muscle collected both from Fish ponds Pattoki and Balloki Headworks. The present situation can be considerably improved by taking effective measures such as better cleaning of waste water from the industrial enterprises and urban agglomeration as well as by installing new waste water treatment plants.

Publisher: 2013Dissertation note: The present project was planned to study gradual replacement of Cirrhinus mrigala with Cyprinus carpio and its impact on pond ecosystem. 900 fish individuals belonging to six species viz. Catla catla, Labeo rohita, Cirrhinus mrigala, Ctenopharyngodon idella, Hypophythylmichthys molitrix and Cyprinus carpio were stocked in four earthen ponds. The dimensions of each pond were 220 X 198 X 7 feet length, breadth and depth. The stocking density in pond 1 (T1) was C. catla 150, L. rohita 200, C. mrigala 200, C. idella 150, H. molitrix 150 and C. carpio 50. The stocking density of C. mrigala and C. carpio in pond 2 (T2) was 150 and 100, in pond 3 (T3), 100 and 150 and in pond 4 (T4) it was 50 and 200, respectively while the stocking density of all the other four fish species remained constant in all the four ponds. All the fish were fed with a diet of 25.16% crude protein @ 2% body weight. C. idella and C. mrigala showed maximum growth in T1, C. catla and H. molitrix in T2, L. rohita and C. carpio in T3. Maximum growth was observed in T3 followed by T4, T1 and T2. Among fish species C. idella and C. carpio showed higher growth rates than the rest of fish species. Our results reveal that in polyculture system stocking density of C. mrigala and C. carpio in a ratio of 1: 1.5 gives better results.
In treatment 1 pond higher SGR 0.552% was observed in H. molitrix and lower 0.238 in C. carpio. Similarly, in T2 pond maximum SGR 0.703% was observed in H. molitrix and minimum 0.260% in C. idella. Maximum SGR 0.409 % was observed in H. molitrix in on T3 pond while it was minimum 0.153 in C. mrigala. In T4 pond maximum SGR 0.322% was observed in L. rohita while it was minimum 0.139 in C. idella.
During present study major water quality parameters remained in the favorable range for fish culture, average value of temperature remained in the range 27.08 to 28.66 oC, salinity 0.86 to 0.99 ppt, DO 5.15 to 5.91 mg/L, EC ranges from 2.23 to 2.32 Ms/cm and pH ranges from 8.04 to 8.23 were observed within the optimum range throughout the experiment. Statistically significant variations in nitrate content of water were observed in T1 and T4 ponds while non-significant differences for nitrates were recorded in T2 and T3 ponds. Similarly, phosphates in water showed significant differences in T1 as compared to T3 and T4 ponds while T2, T3 and T4 showed non-significant differences for phosphates. Light penetration varied significantly between T1, T2 and T4 ponds and its values varied from minimum 18.17±0.946 cm in T4 to maximum 25.50±1.057 cm in T1 ponds
The phytoplankton density was similar in ponds during the given period except the start month of study the low plankton values in April due to the ponds being filled with fresh water and immediately stocked with fish. The density of zooplankton components was higher under T3 where silver carp gained more weight. A total of 11 species of Bacillariophyceae, 10 species of Cyanophyceae, 30 species of Chlorophyceae, 2 species of Euglenophyceae, 3 species of Cladocera, 4 species of Copepoda, 9 species of Myxophyceae, 9 species of Crustacea, 11 species of Rotatoria and 1 species of Olygochaeta were identified. The number of identified species was relatively small, consisting of eurytopic species only, possibly as a result of the heavy activity these ponds suffered. Microcrustaceans, being valuable food organism for many fish species, were represented by genera Daphnia, Cyclops, Bosmina, Moina and Scapholeberis.

Possible Causes Of Selective Lernaea Attack On Different Fish Species
by Farzana Abbas | Prof. Dr. Muhammad Ashraf | Dr. Arshad | Dr. Sumaira Abbas.
Material type: ; Format:

; Literary form:
drama
Publisher: 2013Dissertation note: The present study was managed to investigate the possible causes of selective Lernaea attack in different fish species. Planned studies were conducted in five trials. During the first trial lernaea susceptibility and infestation were observed in indigenous major and exotic Chinese carps. Studies were conducted in 4 earthen ponds with two ponds per experimental group. Fishes in the both groups were fed isonitrogenous diet containing 40% crude protein formulated with different feed ingredients. Fishes were identified and examined for the presence of Lernaea species. The parasites were removed and preserved in vials containing 5% formalin. Other growth parameters i.e. average weight gain, average increase in length while physico-chemical analysis including dissolved oxygen, pH, electrical conductivity, water temperature, salinity and total dissolved solids, Chlorides, Phosphates ions (PO4-2), nitrates (NO3) and secchi disk visibility were recorded. The fishes were treated with Tender, an organophasphate (DDVP (Dichlorvos) or 2, 2-dichlorovinyl dimethyl phosphate) for the control of lernaea.
The results showed that C. catla is the most susceptible fish to L. cyprinacea infestation and its appropriate control for conservation of this precious and declining fish is of extreme importance. Thunder is biologically safe as it is biodegradable and degenerated after 36 h without causing any negative effect on the water quality parameters and other water flora and fauna. Treatment of L. cyprinace with 'Thunder' (0.10-0.25ppm) gives promising results without adverse effect on fish life. Though DDVP worked well in its control but its heavy infestation really weaken fish incapacitating its feeding and competing abilities with its counterparts.
In the 2nd trial, comparison of bio-chemical profile was observed on healthy and infected Indian and Chinese major carps. The experiment was managed in four earthen rearing ponds (59m x 30.5m x 1.8m). There were two-groups, one group without any treatment served as control and the second as treatment. At the outset of trial all the fish species were weighed, measured and comprehensively examined for presence of L. cyprinacea and general health condition. Fishes from both groups were dealt uniformly except administration of regular applications of DDVP (0.25ppm in treatment group while no any medication in control group. Water quality parameters DO, pH, electrical conductivity, water temperature, salinity and total dissolved solids, chloride ion (Cl-1), phosphate ions (PO4-2) nitrates (NO-3) and light penetration were recorded. Samples of healthy and infected fishes of each species were collected for proximate composition (moisture, ash, crude protein, crude fat) and minerals (Iron, Zinc, Calcium, Copper and Magnesium) and phosphorous analysis.
The results showed that dry matter, fat and crude protein percentages were significantly decreased in lernaeid fishes. Moisture and ash contents of fishes increased in infected fishes as compared to healthy and treated fish. A slightly lower level of protein (12.65±0.49) and fat (7.30±0.28) in C. catla was observed than rest of the species. The protein was the highest (26.00±4.24) in L. rohita while the fats were the highest (10.55±0.92) in C. mrigala and C. carpio the second highest. Similarly looking at mineral profile there is not much difference, so it is hard to say that level and type of nutrients are solely responsible for L. cyprinacea attack. Mineral composition of infected fish indicated that minerals balance upsets during disease condition. Pathogenicity is a complex of so many factors, which encompass environmental, biological, and physiological so still lot remains to be explored before issuance of any concrete conclusion and recommendation that which factor is more active and critical in inviting and attracting this parasite.
In the third experiment, various blood indices were compared among Chinese and Indian major carps from the perspectives of their resistance against lernaeaosis that included probable role of blood and its components in reception of L. cyprinacea in some commercially important locally culturable herbivorous fish varieties while repulsion in others living under similar environment.
Healthy samples of each fish species were selected and blood was immediately drawn by puncturing gill lamellae, caudal vein and heart of both male and female of each representative experimental species. Blood parameters including Red Blood Cells (RBC, 10 -6/µL), White Blood Cells (WBC, 10-3/µL) and Platelets (10-3/µL) in blood from experimental fish species were counted by placing sample on haemocytometer grids. Differential Leucocyte Count (DLC), red blood indices, blood chemistry and ESR were determined for males and females of experimental fishes.
The results revealed that females of each species have relatively higher values for blood indices as compared to males. C. carpio has maximum number of granulocytes that may support the fish against the parasitic attack. C. catla has the lowest values for the immunoglobulin Ig M as compared to the species which showed less susceptibility.
In the 4th trial, healthy fishes of major and Chinese carps were collected from commercial rearing and grow out ponds. Each fish weighed 830 ± 316 g on the average. For mucus collection, fishes were bathed in Potassium permanganate (KMnO4) solution (8.0 ppm) to remove microbial or fungal infection/infestation. Samples were centrifuged at 12000×g at 4 ?C for 10 minutes and stored at -40?C in biomedical freezer. Bradford Micro Assay technique was applied to determine protein contents. Bradford protein solution (50 ?L) was added to each well and absorbance was recorded at 595nm. Standard curve was drawn from various but consecutive dilutions of BSA solution and protein concentrations in different samples were calculated. Electrophoresis was carried out with slight modifications. 15% separating and 4% staking buffer were used to run the SDS- PAGE under constant voltage of 120. Fermentas PageRuler™ protein ladder was used as the standard marker for non reducing protein. The gel was stained with PageBlue™ (Fermentas) stain for identification of protein bands for molecular weight determination. Lectin activity and Alkaline Phosphatase test were determined. Mucus was incubated with 4 mM p-nitrophenyl phosphate in ammonium bicarbonate buffer (100 mM) with 1 mM MgC12 (pH 7.8) at 30°C. The increase in optical density (OD) was measured continuously for 2 to 3 hours at 405 nm using a micro plate reader.
The results showed that lectin activity was the highest in C. idellus (109) indicative of low resistance while it was the lowest (21) in H.molitrix which was completely parasite free. Alkaline phosphatase level was the highest in C. catla, C.idella was the second highest and was the lowest in C. carpio. Protein concentrations were the highest in C. idella (3.29 ± 0.13 mg/ml) and C. catla (3.02 ± 0.57 mg/ml) while it was the lowest in C. carpio (1.80 ± 0.09). C. catla contained the highest molecular weight proteins (100 kDa) while C. carpio has one unique protein band of 14.13 kDa not present in any other species in current setup.
In the 5th experiment, the lernaea were observed in the month of June to August. Lernaeied infestation was observed in all experimental fishes except in C. carpio. After appearance of infestation fishes were treated with Thunder (DDVP- an organophasphate) to eliminate the parasite. Parasite free C. idellus, H. molitrix, L. rohita, C. mrigala, C. catla and C. carpio were collected with an average weight of 830 ± 316 g each were used for studies on whole-body amino acid composition. Triplicate samples of each species were over dried after evacuating their gut contents. Dried samples were then finely powdered, sieved and vacuum hydrolyzed in 2 ml of 6 N HCl at 1lO°C for 24 hours. Total amino acid composition was determined by o-phthaldialdehyde (OPA) method using an Agilent chromatograph, revers-phase high performance liquid chromatography (HPLC). The results showed that the essential amino acids (arginine, lysine, phenylalanine, tyrosine, histidine and leucine) play a major role in the immune system. It is revealed that amino acids will widely become cost-effective neutraceuticals for improving health and preventing infectious disease in animals. C. carpio have no infestation due to increased numbers and concentrations of essential amino acids when compared to other species of Indian and Chinese major carps. C. catla, C. idella and H. molitrix have the lowest number and concentration of essential amino acids and hence appeared more susceptible to lernaea attack.
Finally it was concluded from the entire study that C. carpio may have high resistance for the L. cyprinaceaea as compared to the other experimental fishes. It possesses higher values for Ig M-immunoglobulin as compared to C. catla that indicated its high immunity against the parasite. Similarly C. carpio has maximum number of granulocytes (WBCs, esinophils, basophils and lymphocytes) that may support the fish against the parasitic attack. SDS-PAGE analysis of mucus revealed that C. carpio has one unique protein band of 14.13 kDa not present in any other species in current setup. This protein band may indicate the presence of lysozyme enzyme that actively participates against the invading pathogen. Essential and non-essential amino acids concentrations were also higher in the C. carpio that play a vital role in immunity especially arginine, lysine, phenylalanine, tyrosine, histidine, leucine, glutamic acid and aspartic acids.

Publisher: 2013Dissertation note: Catheter-associated urinary tract infections (CAUTIs) are most common type of nosocomial infection. This study was designed to recognize and identify the bacterial pathogen of catheter-associated urinary tract infection in patients, the sensitivity pattern of bacterial pathogens to commonly used antibiotics and the synergistic effect of antibiotics with ascorbic acid to improve the efficacy of antibiotics. The prospective, observational study was conducted in Sir Ganga Raam hospital Lahore. The urine samples from 100 catheterized patients were collected and were analyzed for its causative /pathogenic organism. Out of 100 patients, 58 patients carried E.coli (27%), Citrobacter (22%), Enterobacter (5%) and Staphylococcus aureus (4%) and these patients were included in study. Sensitivity patterns of Ampicillin, Co-amoxiclav, Ceftriaxone and Ciprofloxacin were checked by Kirby-Bauer disk diffusion method. Uropathogens appeared to be highly resistant against Ceftriaxone (84%), followed by Co-amoxiclave (83%) and Ampicillin (76%).Amikacin and Ciprofloxacin are effective drugs against uropathogens and their sensitivities to Amikacin and Ciprofloxacin were 74% and 71% respectively.
Susceptibility testing of bacteria against antibiotics and ascorbic acid alone and in combination was checked and it was observed that bacterial resistance to Ceftriaxone was reversed with ascorbic acid and the effectiveness of ciprofloxacin was improved with ascorbic acid. In Citrobacter, ascorbic acid antagonized the effects of Amikacin.
Empirical therapy of patients included in study was evaluated by clinical response and their definitive therapy was assessed by observing the adverse effects associated with that drug. Co-amoxiclav produced 100% side effects. Tinnitus (63%) was observed in patients treated with Amikacin while Ciprofloxacin adverse effects were headache and dizziness.
It was concluded in the study that there was high incidence of infection in catheterized patients with resistant bacteria and inappropriate antibiotic therapy. Ascorbic acid may be prescribed prophylactically to catheterized patients and to those who take Ceftriaxone to minimize its resistance in patients. To improve the effectiveness of drugs in CAUTI patients, ascorbic acid may be used with antibiotics.

Publisher: 2013Dissertation note: Vehicular air pollution is a mounting health issue of the modern age, particularly in urban populations of the developing nations. Auto rickshaws are not considered eco-friendly as to their inefficient engines producing large amount of particulate matter (PM), which poses a significant environmental threat.
Major transformations in the environmental composition are principally attributable to the combustion of fuels by automobiles. Motorized gasoline powered two-stroke auto-rickshaws (TSA) and CNG powered four-stroke auto-rickshaws (FSA)are major sources of air pollution in south Asia and produce toxic amount of PM to the environment. In this study, during the first phase, the PM of TSA and FSA was characterized by using proton induced x-ray emission (PIXE) analysis. The observations of the existing investigation recognized significant increase in Al (P < 0.05), P (P < 0.01), and Zn (P < 0.01) from the PM samples of FSA. In addition, the concentrations of Cu, Fe, K, Mn, Mg, Na, S and Si were also observed exceeding the recommended NIES limits. On the contrary, increased concentration of Sr and V were observed in the PM samples from TSA. It is generally believed that FSA generates smaller amount of PM but the data obtained from this study clearly shows that emissions from FSA are comprised of potentially more toxic substances than TSA. The current research is specific to the metropolitan population and has evidently revealed an inconsistent burden of exposure to air pollutants engendered by FSA in urban communities, which could lead to disruption of several biological activities and may cause severe damage to entire ecological system.
The second phase of this study was conducted to ascertain toxic effects on angiogenesis, embryo development, embryonic movement and phytotoxicity of the PM from TSA and CNG powered FSA. Based on high amounts of aluminum quantified during PIXE analysis of PM from TSA and FSA, different concentrations of aluminum sulfate were also tested to determine its eco-toxicological potential. The PM solution from FSA, TSA and Aluminum sulfate exhibited anti-angiogenic potential with reduction in total area of CAM. Morphological evaluation of embryos exhibited varying degrees of hemorrhages in different groups. In case of phytotoxicity screening using Zea mays, the results demonstrated that all three tested materials were equally phytotoxic at higher concentrations in seed germination(p<0.001). Aluminum sulfate proved to be a highly phytotoxic agent even at the lowest concentration examined.
During the last phase, of the study, the MTT assay demonstrated a significant (p<0.001) dose dependent cytotoxic effect for TSA, FSA and aluminum sulfate on the BHK-21 cell line, establishing that the PM from FSA is a highly cytotoxic material. Mutagenicity was assessed by fluctuation Salmonella reverse mutation assay adopting TA100 and TA98 mutant strains with (+S9) and without (-S9) metabolic activation. Despite the fact that different concentrations of PM from both sources i.e. TSA and FSA were highly mutagenic (p<0.001) even at lower concentrations, the mutagenic index was higher in TSA. The chronic toxicity study revealed that chronic exposure to PM emitted from FSA and TSA resulted in peribrochiolitis, emphesema and infilteration of leukocytes in lung tissues. On the other hand liver, cardiac and kidney tissues exhibited degeneration and necrosis. The data shows that all tested materials are equally ecotoxicand if the existing trend of atmospheric pollution by auto-rickshaws is continued, air-borne metals/heavy metals will seriously affect the normal growth of local inhabitants and increased contamination of agricultural products, which will amplify the dietary intake of toxic element and could result in genetic mutation or long-term health implications.

Publisher: 2013Dissertation note: Metformin most commonly prescribed oral anti hyperglycemic drug for type 2 diabetes whereas Sitagliptin recently approved oral antidabetic drug for type 2 diabetes were evaluated for their mutagenic and genotoxic potential alone and in combination with three artificial sweeteners (Saccharin, Aspartame and Acesulfame-K) normally consumed by diabetic individuals.
In this research project Ames Salmonella/microsome assay was performed to check the mutagenicity of Metformin and Sitagliptin alone and in combination with artificial sweeteners using mutant Salmonella tester strains TA100 and TA98 with and without the S9 whereas Genotoxicity was evaluated by Single Cell Gel Alkaline Electrophoresis/Comet.
The results indicated that Metformin alone showed mutagenic effect at 120µg/plate against TA100 with S9mix. However Metformin when tested in combination with artificial sweeteners, significant enhance in mutagenicity occurred only against TA100 with and without S9. Sitagliptin displayed mutagenic potential only to TA98 with S9mix at the concentration of 3040µg/plate. In addition significant enhance in mutagenicity occurred when tested in combination with artificial sweeteners against both strains with and without S9. In case of genotoxicity both Metformin and Sitagliptin results indicated significant increase in DNA damage in dose dependant manner as compared to negative control. Though Metformin and Sitagliptin in combination with artificial sweetener did not reveal any significant boost in the genotoxicity relative to when they were tested alone.

Publisher: 2014Dissertation note: Background:
This project was designed to evaluate the anthelmintic efficacy of Chloroformic extract of Calotropis procera leaves against sheep nematodes. For this purpose hundred sheep positive for nematodal infection in BLPRI Kherimurat were selected after fecal examination.
Methodology:
The hundred animals were divided into 5 groups (Group A, Group B, Group C, Group D and Group E) having 20 animals in each group. Fecal eggs counts (EPG) and biochemical tests like the Alanine aminotransferase (ALT), Aspapartate aminotransferase (AST), Alkaline phosphatase (ALP), Albumin, Bilirubin, Creatinine and Urea were done on the day zero of the treatment. For further study, Group A served as an un-treated control. Group B, Group C and Group D were given the Chloroformic extract of Calotropis procera leaves at the dose rate of 3, 6 and 12mg/kg body weight by oral route respectively. Group E was given the Moxidectin at the dose rate of 0.2mg/kg body weight by subcut route. The biochemical tests on the day 3 showed no change in the normal level of the ALT, AST, ALP, Albumin, Bilirubin, Creatinine and Urea. The fecal EPG of all the groups were done on the day 7th and day 14th post treatment. The efficacy of the Group A and Group B was 0% both on day 7th and day 14th post treatment. The efficacy for the Group C was 19.40% and 42.53 % on the day 7th and day 14th post treatment respectively. The Group D showed the efficacy of 80.215% on day 7th and 91.36% on the day 14th of the treatment. The efficacy for the Group E was 85.97% and 93.29% on the day 7th and 14th respectively.
Statistics:
The data from the fecal eggs count and biochemical tests were analyzed by using the ANOVA and LSD.
Conclusion:
The Chloroformic extract of the Calotropis procera leaves have maximum anthelmintic effect at the dose rate of 12mg/kg body weight having no biochemical changes in the blood.

Publisher: 2013Dissertation note: This 9-month study extending from March 1, to November, 30, 2012 was conducted to find out the effect of different feed ingredients on growth, haematology and vital organs in juvenile Labeo rohita. The experiment was performed to find out the cost-effective substitutes of fishmeal and their effect on growth, digestive enzymes activity, blood profile, histology of intestine and flesh quality was monitored. To obtain the said objectives the experimental fish, Labeo rohita was subjected through three different research trials. i. A 3-month research trial was conducted to evaluate the effect of different plant/animal origin feed ingredients on growth, feed conversion ratio (FCR) and survival of fingerling Labeo rohita. Fish was fed on fish meal, guar meal, corn gluten meal (30%), soybean meal, sunflower meal, rice polish, cotton seed meal, canola meal and rape seed meal individually. Statistical analysis revealed significant differences (P?0.05) in growth, average weight gain, average length increase and specific growth rate among various ingredients. The highest average weight gain 27.162±6.950g and average length increase 6.153±0.833cm was observed in fish fed on guar meal while same was lowest 5.327±1.067g and 1.858±0.137cm, respectively in fish fed on corn gluten. However, fish showed better FCR values (2.01±0.08) when fed on guar meal while the FCR was very poor (9.57±48) for corn gluten (30%) fed group. The survival rate was highest (100%) for soybean meal fed group and lowest (70%) in canola and rapeseed meal fed group. ii. During second 3-month feeding trial, the effectiveness of individual feed ingredient from either plant or animal origin on growth, body composition, enzymes activity, haematology, histology and flesh quality of Labeo rohita was observed. The experiment was conducted in ten fiber glass tanks having size 12 ft x 4ft x 3 ft (length x width x depth). Single ingredient was considered as an independent treatment, hence guar meal, soybean meal, cotton seed meal and canola meal were considered as an independent treatment and fishmeal which was considered as a superior ingredient due to its ideal nutrient balance served as control. Ten juvenile Labeo rohita having an average weight of 200±2.33 g were harvested indiscriminately from the bulk and stocked in each fiberglass tank. Two tanks were randomly allotted to each treatment and control. Each group received uniform ration @ 4% of total fish biomass twice a day. Results revealed significant differences (P?0.05) in growth, FCR and specific growth rates among treatments. Weight gain was the highest in guar meal fed fish while the lowest on fish meal. Body composition of fish showed slight variations in fat contents with no differences in other nutrients though chemical composition of individual ingredient varies a lot. Minerals specifically Na, Ca, Fe, Zn, and Cu significantly differed (P?0.05) among treatments which might be linked with their variable release in digestive system of fish in the presence of various anti-nutritional factors. For different feed ingredients protease activity varied significantly (P<0.05) between anterior and posterior part of the intestine and also that of whole intestine when compared among various treatment groups. While amylase activity differed significantly when enzyme activity compared from the homogenate of whole intestine but not when compared partly. WBC, RBC, Hct, HB, PROT, ALB and GLOB showed significant (P<0.05) differences for blood samples of the fish fed with different feed ingredients while values of MCV, MCH, MCHC and ESR remained uniform. The feed ingredients differently affected the liver and intestinal cells. No difference was observed when fried fish fed on different ingredients were compared among each other indicating that ingredients with nominal variations in chemical composition do not leave much after effects on fish flesh. iii. Third 3-month trial was conducted to evaluate the effect of plant-animal feed and/or plant by-product based feed on growth, body composition, enzymes activity, haematology, histology and flesh quality of Labeo rohita. Fish fed on rice polish alone served as control (T0). Previously selected potential fish feed ingredients were grouped together with two ingredients in each isocaloric test diet which served as an independent trial during these studies. Group 1(T1) contained guar meal and canola meal, group 2(T2) soybean meal and cotton seed meal, group 3(T3) guar meal and cotton seed meal, group 4(T4) soybean meal and canola meal and group 5(T5) fishmeal and canola meal. Each group including control had two replicates. 12 earthen ponds with uniform area of 0.03 ha each, were randomly stocked with 100 fish (average weight 200±4.43g) in each following standard stocking protocols. All the 12 ponds were then randomly allotted to individual treatment including control group. Experimental fish were fed @ 4% of their wet biomass twice a day except Sundays which was kept open providing fish an opportunity to clean left over feed from the previous day. Better growth rate, food conversion ratio (FCR) and specific growth rate (SGR) in T3 than rest of the treatments including control suggest that guar meal and cotton seed meal is much better option to include in future feed formulations for maximum performance and minimum feed wastage. This preposition will minimize feed providing cleaner and healthy environment to fish ultimately enhancing stocking rate and fish production. Proximate analysis of dried and ground fish samples showed higher protein values in T4, fat in T2, moisture contents in control, dry matter in T1 and ash in T5. Mineral composition of Labeo rohita showed statistically significant (P ? 0.05) differences in Na, Ca, Fe, Zn and Cu content. Amylase concentration showed non-significant differences in anterior, posterior parts and the whole intestine in all the treatment and control ponds except T5 while protease concentrations were statistically significant (?0.05) in anterior and posterior part within the same group as well as among various groups. Enzymatic activity in whole intestine also varied significantly when compared among groups. Haematological parameters viz. WBC, RBC, ALB, GLOB and PROT differed significantly (?0.05) among all the treatments. Disrupted hepatic cords and hepatocytes showing pyknotic nucleus were observed in T1, moderate infiltration of fat vacuoles in T2 and, T4 caused vacuolar and hepatic cord degeneration while fish from T0 were subjected to severe vacuolation in hepatocytes. Non-significant differences in flavor, juiciness, and oiliness of fried fish from all the treatments and control ponds indicated that the sensory attributes of fish flesh were not affected by feeding fish with blend of various ingredients. It is concluded that the response of body organs varies with varying feed stuffs and the feed items have pronounced effect on enzymatic activities, hematological and histological parameters in juvenile Labeo rohita. During present study fish showed comparatively better growth when fed with guar meal as a single feed ingredient or combined with cotton seed meal than the rest of feed ingredients either offered individually or in combinations. The study provides base line information and will help aquaculture nutritionists to formulate cost-effective feeds.

Publisher: 2014Dissertation note: Antibiotic resistance is increasing along with the increasing use of antibiotic for the treatment of infectious diseases. The in-vitro study was designed to observe the reversal of
antibiotics resistance in Methicillin-resistant Staphylococcus aureus by non-antimicrobial
agents.
One hundred pus samples were processed for isolation and identification of MRSA.
Out of 100, 37 (37%) islotes were Gram +ve cocci, from these 37 isolates 34 (92%) turn red
colour of mannitol salt media to yellow and 23 (62%) gave +ve catalase and coagulase. In
this study Antibiotic Sensitivity Test was performed on pure culture of MRSA strain by
applying disc diffusion method. Out of 23 pure MRSA isolate, 100% isolates were
methacillin resistant, 79% isolates were co-amoxiclav resistant, 30% isolates were
meropenum resistant, 8% isolates were vancomycin resistant, 26% isoltes were moxifloxacin
resistant and 39% isolates were linezolid resistant. Reversal of antibiotics resistance was
observed by MIC or serial dilution method, using non antibiotic agents like Amiloride,
Lansoprazole and Promethazine, Concentrations of non-antibiotic agents 1024ìg, 512ìg,
256ìg, 128ug, 64ìg and 32ìg were used in combination of antibiotics to reverse the
antibiotics resistance in MRSA. These non antibiotic agents may cause the alteration in
mechanisms by which microorganism develop resistance. The collected data analyzed by
applying analysis of variance (ANOVA) through SPSS 16.0 computer software. Now we would be
able to treat some lethal infection caused by MRSA, and help to increase patient compliance
and decrease the cost of therapy.

Publisher: 2013Dissertation note: The present study was designed to explore the effects of aqueous and ethanolic extract of leaves and seeds of Eugenia jambolana on angiogenesis by means of the chicken chorioallentoic membrane assay. The Eugenia jambolana was collected from the locality of Lahore. Sequential dilutions were made with distilled water. Eggs were taken from local hatchery and divided into 4 groups. Each group was comprised of five eggs. The eggs were incubated at 37 C0. At day 4, 3-4 ml albumin was removed with the help of syringe. At day 5, sample solutions of various concentrations were applied to chorioallentoic membrane (CAM). After 24 hours, the change in CAM was observed by taking the images. SPIP was utilized for computerized measurements of the diameter of blood vessels and CAM. Overall area of the CAM was also drastically minimized among all groups treated with sample solutions.
The data was analyzed for statistical analysis by using SPSS software (version 13 for windows). ANOVA was performed to determine significance among different groups. The value of P<0.05 was considered as significant.
Different extracts of Eugenia Jambolana exhibited anti-angiogenic potential in the following order. WS > WL = ES > EL. In case of WS 4% solution area of CAM is 285.66 mm2, WL 4% 586.77 mm2, ES 4% 567.47 mm2 and EL 4% 634.23 mm2 while in case of negative control area of CAM 2473 mm2 . The extracts exhibited anti-angiogenic potential in variable magnitude. Dilutions of water extract of seeds exhibited most anti-angiogenic potential (p<0.01) in comparison to other treated groups. Collectively, these observations show that extract of Eugenia jambolana seeds and leaves contains polar compounds that ceased growth, primary vessel formation and cell propagation in CAMs.

Publisher: 2013Dissertation note: Plant products play an important role because of their medicinal activity. A wide variety of active phytochemicals peptides have been found to possess therapeutic applications against various functionally and genetically diverse viruses. Influenza A viruses (IAV) causes acute respiratory diseases in humans, birds, and other mammals, representing one of the major threats to public health.
In this study, the antiviral activity of Allium sativum L., Allium cepa L., and Zingiber officinale Roscoe against Avian Influenza H9 virus was evaluated in ovo. The aqeous extracts of Allium sativum L., Allium cepa L., and Zingiber officinale Roscoe were prepared by using macerate technique. From the macerate, nine different dilutions i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml of the extracts were prepared in normal saline. For each plant extract; Allium sativum L., Allium cepa L., Zingiber officinale Roscoe 100 embryonated chicken eggs were assigned to 20 groups, each group containing 5 embryonated chicken eggs (nine for antiviral activity, nine for cytotoxic activity, and two groups were kept positive and negative control respectively) and marked them with lead pencil. The different concentrations of the plant extracts were mixed with virus and 0.2 ml inoculum was inoculated to 9th to 10th day embryonated chicken eggs along with positive and negative controls containing only virus and normal saline respectively. The embryonated chicken eggs were incubated at 37oC and were checked after 12-72 hrs. After 72 hr post inoculation, all the eggs were chilled in refrigerator at 4oC for 12 hrs and the allantoic fluid was harvested. The antiviral activity was calculated as embryo survival percentage, positive or negative spot Hemagglutination activity and determination of virus titre by Hemagglutination Test. The cytotoxicity of Allium sativum L., Allium cepa L., Zingiber officinale Roscoe extracts was evaluated by only inoculating the extracts of respective concentrations as used for antiviral activity in embryonated chicken eggs and incubating for 72 hrs. The results were analyzed by ANOVA by means of SPSS.
All the concentrations of Allium sativum L. were non toxic while three concentrations showing antiviral activity were 8000 ƒÊg/ml, 4000 ƒÊg/ml and 2000 ƒÊg/ml. While in case of Allium cepa L. all the concentration i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml were non cytotoxic and five concentrations i.e. 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml and 500 ƒÊg/ml show potent antiviral activity. In case of Zingiber officinale Roscoe two concentrations 8000 ƒÊg/ml, 4000 ƒÊg/ml were virucidal and all concentration 8000 ƒÊg/ml, 4000 ƒÊg/ml, 2000 ƒÊg/ml, 1000 ƒÊg/ml, 500 ƒÊg/ml, 250 ƒÊg/ml, 125 ƒÊg/ml, 62.5 ƒÊg/ml and 31.25 ƒÊg/ml were non cytotoxic. So the present study suggested the presence of antiviral activity of plant extracts of Allium sativum L., Allium cepa L., Zingiber officinale Roscoe, so they can be used for prevention and treatment of various viral diseases.

Publisher: 2014Dissertation note: Background
Opportunistic pathogens represent the type of pathogens which infects only those individuals
with impaired immune system and lead to diseases that can be severe, debilitating and difficult to
treat in immunocompromized host. These opportunistic pathogens include different bacteria,
viruses and fungi. This study was designed to identify the opportunistic bacterial pathogens
pseudomonas and Citrobecter in immunocompromized chronic liver disease (CLD) patients.
This study was performed to analyze sensitivity pattern of bacterial pathogens to commonly used
antibiotics quinolones, aminoglycosides, cephalosporin and co-trimoxazole and to evaluate the
synergistic efficacy of different combination s of antibiotics. The study was conducted on
different CLD patients admitted in different medical wards of Sir .ganga Ram Hospital Lahore.
Aim
By using blood and urine culturing technique and different biochemical tests opportunistic
pathogens Pseudomonas and Citrobecter in CLD immunocompromized patients belonging to
different age group were determined. Combination therapy of quinolones, aminoglycosides,
cephalosporin and sulpha drugs were effective against the bacterial pathogens Pseudomonas and
Citrobecter.
Material and Methods
Clinical sign and symptoms of all the CLD patients who were admitted in the hospital were
noted at the time of admission The patients who start showing sign and symptoms (Fever,
burning micturation, pain) of suspected infection on 2nd and 3rd day of their admission were
included in this study. Blood and urine samples were collected from infected CLD patients with
CHAPTER – 6
SUMMARY
suspected sign and symptoms by using all necessary aseptic precautions with the assistance of
trained professionals. The pathogens were isolated, identified and purified by selective culturing
methods, which were subjected to active growth, during which sensitivity to different antibiotics
was checked. Antibiotic sensitivity test was conducted on pure culture isolates employing the
Kirby Bauer disc diffusion method for the commonly used antibiotics. The diameters of growth
inhibition around the discs was measured and interpreted by using Clinical Laboratory Standards
Interpretations (CLSI).
Statistical Analysis
The collected data was analyzed by ANOVA and Chi-square test on SPSS software (16) .
Results
Pseudomonas and Citrobecter pathogens are now proved to be a multi resistant pathogens and
use of combinations of antibiotics against these pathogens found to be more effective. This study
was performed to evaluate the synergistic effect of different antibiotics combinations against
Pseudomonas and Citrobecter pathogens, so that the chances of recurrent infections among the
immunocompromized hospitalized patients were minimized. It will help to improve the quality
of life of immunocompromized patients through providing information about effective antibiotic
treatment. The effects of different combinations of antibiotics were also analyzed in CLD
patients through evaluating the improvement in infectious disease. It was found during study that
combination of ceftriaxone and amikacin prove to be more effective in clinical settings but in
vitro studies shows the combination of cephradine with gentamycin was 97% susceptible.
