Abstract:
اجريت الدراسة الحالية في البيت الحيواني التابع لكلية الطب البيطري - جامعة البصرة لمعرفة الامراضية السمية لكبريتات الثاليوم على انسجة الجسم المختلفة وبعض المعايير الكيموحيوية للجرذان المختبرية البيضاء Sprague Dawley (Rattus norvegicus). في هذه الدراسة تم | The present study was conducted at the College of Veterinary Medicine - University of Basrah to investigate the effect of Thallium Sulfate on some physiological parameters and histological changes in the Laboratory White Sprague Dawley Rats (Rattus norvegicus). In this study 48 rats were used, that were sexually mature (16 weeks age and 250±50 gm weighing). These animals were divided into four groups each group contain 12 rats. All of these groups administrated orally with : - normal saline ,0.4 ,0.8 ,1.6 mg /kg b. w. of thallium sulfate respectively for 90 days.After ending of this period, all animals were sacrificed after anesthesia by chloroform inhalation for the study. The study includes the effects of thallium sulfate on some biochemical parameters as estimation of serum liver function enzymes ( AST and ALT ) and kidney function enzymes ( Urea and Creatinine ). This study also includes the estimation of serum acetylcholine (Ach) concentration. The present study revealed histopathological effects of thallium sulfate on nervous system, liver, kidneys, eyes, skin, and testis. In addition to its electron microscopic changes were occurred on mitochondria of hepatocyes and cells of proximal convoluted tubules of kidney. The results of this study showed significant increase (P? 0.05) in liver enzymes and kidney function enzymes and acetylcholine concentration in treated groups in comparison with control group. There is also histopathological changes occurred in nervous tissue (brain, spinal cord, and sciatic nerve), liver, kidney, testis, eye, and skin. The ultrastructural changes showed swelling of mitochondria and also an increased in number in rats treated with 1.6 mg/kg b.w. of thallium sulfate in comparison with control group.
