The Effect Of Aflatoxin B1 On The Vitamin A Storage In The Livers Of Broiler Chicks, Berri̇n Salmanoğlu
The Effect Of Aflatoxin B1 On The Vitamin A Storage In The Livers Of Broiler Chicks, Berri̇n Salmanoğlu
Turkish Journal of Veterinary & Animal Sciences
The effect of AFB1 in feed on the liver and serum vitamin A and b-carotene levels and the ability of the liver to stor vitamin A in broiler chicks were investigated. Twenty day-old Ross broiler chicks were randomly allocated into 4 groups with 5 each in the control group, group I, group II, and group III. The chicks of the control group and group I were fed ad libitum on broiler chick growing feed. The chicks of group II and group III were fed ad libitum on feed with AFB1 (4 ppm/kg) feed. On the seventh day, vitamin A palmitate …

The liver damage and obstructions of the biliary tract were evaluated ultrasonographically in experimentally bile duct ligated dogs. Seven healthy dogs of different breeds were used. The common bile duct was double ligated at the duodenal region after clinical and ultrasonographic examinations. After that, clinical examinations, biochemical analyses and examinations of the liver, gallbladder and biliary tract were done ultrasonographically over 6 weeks. All dogs were necropsied and macroscopic and histologic alterations were determined at the end of the study. It was determined that the levels of serum ALT, ALP, GGT and T. Bilirubin were (p < 0.001-0.05) statistically significantly increased after the operation in all dogs. As a result of ultrasonographic examinations, it was determined that the bile ducts and gallbladder were distended, the neck of the gallbladder was larger and more tortuous than normal, hypoechoic sludge was prominent in the gallbladder, and perivascular, multifocal hyperechoic areas appeared in the liver parenchyma toward the end of the study. These alterations were confirmed macroscopically and microscopically at the end of the autopsy in all dogs. We consider that as well as blood serum parameters, ultrasonographic examinations are useful in the early diagnosis of biliary diseases and in differentiating them from hepatic diseases.
Incidence And Pathologic Studies On Liver Telangiectasis In Beef Cattle, Ayhan Atasever, Sevi̇l Atalay Vural, Şenay Berki̇n
Incidence And Pathologic Studies On Liver Telangiectasis In Beef Cattle, Ayhan Atasever, Sevi̇l Atalay Vural, Şenay Berki̇n
Turkish Journal of Veterinary & Animal Sciences
In this study, 3470 livers of beef cattle slaughtered by the Ankara Meat and Fish Company were inspected. In these animals, 82 livers had telangiectasis, and the incidence of lesions was 2.3%. They were characterized grossly by single or multiple red-brown foci, generally 1 to 5 mm in diameter, and occasionally larger. They were located on the parietal surface of the lobus dexter or rarely scattered throughout the organ. Microscopically, dilated sinusoids filled with erythrocytes were observed in initial lesions; the distortion, atrophy and necrosis of hepatocytic cordons were seen in advanced cases. There was no correlation between liver abscesses …
The Levels Of Pyruvate Kinase Activity In Renal And Hepatic Tissues Of Rats With Diabetes Induced By Streptozotocin, Seval Yilmaz, Bi̇lal Üstündağ
The Levels Of Pyruvate Kinase Activity In Renal And Hepatic Tissues Of Rats With Diabetes Induced By Streptozotocin, Seval Yilmaz, Bi̇lal Üstündağ
Turkish Journal of Veterinary & Animal Sciences
In this study, the changes in pyruvate kinase enzyme activities in the liver and kidney tissues of rats with diabetes induced by streptozotocin were examined and the relations with the disease were investigated. Diabetes mellitus was induced in Wistar-Albino rats by the administration of a single intraperitoneal dose of streptozotocin (60 mg/kg body weight). After streptozotocin was injected, the pyruvate kinase activities in the livers and kidneys of the rats were analysed according to Beutler's method on days 3 and 12. It was determined that liver pyruvate kinase enzyme levels in rats with diabetes induced with streptozotocin were decreased on …
