Compensation in pancreatic beta-cell function in subjects with glucokinase mutations.

abstract：:Ciglitazone, 5-[4-(1-methylcyclohexylmethoxy) benzyl]-thiazolidine-2,4-dione, is a new hypoglycemic agent orally active in the obese-hyperglycemic animal models. In C57BL/6J-ob/ob mice, treatment with 100 mg/kg ciglitazone for 2 days elicited a drastic fall in blood glucose. It also decreased plasma insulin, triglycer...
