CLINICOPATHOLOGICAL STATUS OF DUCK PLAGUE AT DINAJPUR DISTRICT MOSTARI, SHABNAM Clinicopathological status of duck plague was investigated at different upazila of Dinajpur district during the period from January to June, 2014. The clinical features emphasiging the mortality and prevalence, necropsy for gross morbid lesions, histopathological features were examined. The farm and flock history, managemental aspects, vaccination status, nutrition, etc. were recorded carefully. The data was collected and statistically analysed. Farmer’s complaint’s about their affected birds were also considered and emphasized. The average mortality rate was recorded as 14.42% and prevalence was 19.81%. The sick birds clinically showed moderate to severe depression, ocular and nasal discharges, ataxia, dypsnia. The affected organs were pathologically characterized as mild to moderate congestion and haemorrhages; misshapen, ruptured cystic ova, and histopathologically characterized as mild to moderate architectural destruction, reactive cell infiltration.

INVESTIGATION OF DIFFERENT PARASITES OF FARMED PIGEONS AT DINAJPUR SADAR UPAZILA RAHMAN, MD. GAUSUR A cross sectional study was conducted to investigate the different parasites in farmed pigeon at sadar upazila of Dinajpur, Bangladesh during January to June, 2017. A total of 122 pigeons (39 young and 83 adult in which 45 male and 77 female) from different farms were examined by faecal, oral and blood sample examination and postmortem examination for histopathological study. The investigation expressed that the highest overall prevalence was ectoparasites 107 (87.70%) followed by helminthes 96 (78.69%) and protozoa 71(58.20%). In this study, the frequency of Echinostoma sp., Raillietina sp., Ascaridia sp., Capillaria sp., Ornithostrongylus sp., Eimeria sp., Trichomonas sp., Haemoproteus sp., Columbicola columbae, Menopon sp. and Lipeurus sp. were found to be 24(19.67%), 46(37.67%), 51(41.80%), 38(31.15%), 15(12.30%), 45(36.89%), 47(38.52%), 39(31.97%), 96(78.67%), 55(45.08%) and 75(61.48%) respectively. The age and sex related prevalence of helminth revealed that adults 68(81.93%) were more susceptible than young 28(71.79%) and females 62(80.52%) were more prevalent than male 34(75.56%) but these were statistically insignificant (P>0.05). Further, youngs 25(64.10%) were more prone to protozoa than adults 46(55.42%) and the higher prevalence of protozoa was found in female 50(64.94%) in compare to male 21(46.67%) which were not statistically significant (P>0.05). Association of age and sex with ectoparasites indicated that the prevalence of ectoparasites was significantly (P<0.001) higher in adult 80(96.39%) than young 27(69.23%) and also significantly (P<0.05) higher in female 50(64.94%) than male 21(46.67%) pigeons. The mean intensity of Echinostoma sp., Raillietina sp., Ascaridia sp., Capillaria sp., Ornithostrongylus sp., Eimeria sp., Trichomonas sp., Haemoproteus sp., Columbicola columbae, Menopon sp. and Lipeurus sp. was 2.50±0.30, 4.30±0.35, 3.80±0.29, 2.53±0.23, 1.92±0.24, 4.38±0.38, 4.53±0.42, 7.82±0.61, 17.32±0.82, 14.47±1.13 and 11.91±0.85 respectively. Histopathologically found that degeneration, distraction and desquamation of papillae, villi and epithelium of intestine. The results indicate that pigeons of this area are very much susceptible to different endo and ectoparasites which cause great economic loss of the farmer. A Thesis By MD.

PREVALENCE OF TICK INFESTATION IN CATTLE AT SADAR UPZILA OF DINAJPUR DISTRICT ROZARIO, DIPA The study was designed with an aim to determine the overall prevalence of tick infestation in relation to age, sex, breed, health status, season, management system and affected body parts of the cattle at Sadar upzilla of Dinajpur district during the period from January to June, 2017. The investigation was done by collecting ticks with fine forceps and identifying ticks by preparing temporary and permanent slides. A total of 140 cattle (male 45 and female 95) were examined. Among them, 62 (44.29%) were found to be infested with three species of ticks namely Rhipicephalus sanguineus, Boophilus microplus and Hemaphysalis bispinosa. The prevalence of tick was higher in case of Rhipicephalus sanguineus (27.14%) followed by Boophilus microplus (15.71%) and Hemaphysalis bispinosa (1.43%). The results revealed that the prevalence was significantly (P<0.05) higher in female cattle (52.63%) than in male (26.67%). Malnourished cattle were vulnerable (51.85%) to tick infestation than the cattle with normal body condition (33.90%). In age groups, highest infestation was found in calf (< 6 months) (58.33%) followed by adults (> 2 years) (47.05%) and the lowest in young (≤ 2 years) (33.33%). Tick infestation was more prevalent in local (46.24%) cattle than the cross-bred (40.43%) cattle. In case of cattle management system significantly (p<0.005) higher prevalence was observed in cattle reared under extensive system (65.38%) than the intensive (47.37%) and semi-intensive (34.21%) systems. Prevalence was significantly (p<0.001) higher in rainy (54.17%) season than summer (33.82%) season. Ticks were distributed in different parts of the host body such as ear, neck, dewlap, base of horn, eye, tail, perineum, udder and body surface. Among the body parts, ear (35.71%) was the most affected part and tail (3.71%) was the least. It is concluded that tick infestation is a threat to the cattle population at Sadar upzilla of Dinajpur irrespective of age, sex, breed, health status, seasons of the year, management system and affected body parts. This might hamper cattle production in this area. Hence attention in cattle management and appropriate control strategies are need to be initiated to control ticks in the study area.

EFFECT OF CINNAMON CASSIA EXTRACTS ON HYPERGLYCEMIA AND RENAL FUNCTION IN STREPTOZOTOCIN INDUCED DIABETIC MICE CHAUDHARY, AmAR NATH Background: Diabetes mellitus (DM) is defined as a group of metabolic diseases manifested by hyperglycemia which results from defects in insulin production and/or insulin action. The present study was conducted to demonstrate the diabetogenic effect of Streptozotocin in Mice. Conventional drug treatment for diabetes mellitus carries risks that lead to many adverse effects such weight loss, hypoglycemia and many others. Asian countries including India, Bangladesh and Nepal are rich in natural resources and medicinal plants useful in the treatment of diabetes. To investigate the antidiabetic or anti-hyperglycemic effect and renal profile restoration effect of the Cinnamon cassia extract on Streptozotocin induced diabetes in experimental mice. The extract of cinnamon cassia was tested for its efficacy in Streptozotocin at a dose 100 mg/ kg of body weight induced diabetic mice. Aim of the study: To investigate the effect of Cinnamon cassia extracts on hyperglycemia, and renal profile in Streptozotocin induced diabetic mice. Methods: Thirty six male Swiss albino mice were kept in six different groups and each group have six male Swiss albino mice for 21days. Group T0 served as normal controls; Group T1 Streptozotocin induced 100 mg/ kg of body weight served as positive control mice,; Groups T2, T3 and T4 mice were also Streptozotocin induced 100 mg/ kg of body weight and mice treated with 300 mg/kg, 400 mg/kg and 500mg/kg of Cinnamon extracts (70% ethanol), respectively; and Group T5 were induced mice Streptozotocin 100 mg/ kg and treated with 5mg/kg Glibenclamide drug. The effect of extracts on hyperglycemia, and renal function were tested by chemistry analyzer. Results were analyzed using one way ANOVA at a 5% level of significance. Results: The fasting blood glucose level was significantly (p<0.05) reduced at 400mg/kg and 500mg/kg of Cinnamon extract concentration as compared to the diabetic group. It also reduces urea and creatinine in induced diabetic mice. Conclusion: Reduction in the fasting blood glucose, urea and creatinine by Cinnamon extract indicates that it has anti-hyperglycemic, and renal failure restoration effect in Streptozotocin induced diabetic mice.
