title: Effect of streptozotocin on transaminases, creatinine and urea in serum of rats.
abstract: This study investigates the diabetes-induced lesions in liver and kidney and in addition the possible side effects of the diabetogenic substance streptozotocin (SR) on these organs in non-diabetic animals. 5-week-old female Wistar rats were injected 65 or 130 mg SR/kg body mass. Some animals of the drug group did not become hyperglycemic; thus it was possible to separate the drug effect from the diabetic influence on liver and kidney. In serum investigations some metabolic changes concerning the activities of the liver enzymes aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and the concentrations of urea and creatinine up to 30 days after drug application were studied. SR in hyperglycemic animals causes a time and dose dependent rise in all investigated parameters. Also in normoglycemic rats a significant increase in alkaline phosphatase and in creatinine was observed after 10 days. After 21 and 30 days there were no differences compared to untreated control rats, whereas elevated levels were observed in the hyperglycemic rats. Thus our results support the view of a short damaging effect of SR on liver and kidney without inducing a diabetic state; in hyperglycemic rats the damaging effect is more pronounced.
