Male Japan white rabbits were given orally with two doses of tricyclohexyltin hydroxide (TCHT, 250 mg/kg body weight) at 48 hr intervals and their carbohydrate and lipid metabolisms were investigated 48 hr after the last administration. Elevated fasting blood glucose levels and a significant in hibition of insulin (IRI, immunoreactive insulin) release in response to the intravenous glucose infusion were observed. Microscopic examination of pancreatic islets did not reveal any histological alteration. Plasma triglyceride levels were elevated in the TCHT-treated rabbits. Ultracentrifugation of plasma lipoproteins revealed a marked increase in chylomicron+VLDL (very low density lipoprotein) fraction. Rates of triglyceride secretion into plasma were not different between the TCHT-treated and the control animals. These data suggest that TCHT induces hyperglycemia and hyperlipidemia in rabbits, and the disturbance of metabolism seems to be related to the inhibition of insulin release from the pancreatic islets by TCHT.
