[Endocrine and exocrine functional disorders in pancreatic diabetes].

In diabetic diseases of pancreatic origin we find three typical patterns of insulin secretion. The different insulin secretion allows a clear distinction of a diabetes of the maturity onset type and of the juvenile onset type type on the one hand and of a diabetes caused by a pancreatitis on the other hand. In a pancreatitis we see the expected reduction of the exocrine function. In the so called maturity onset diabetes a slight reduction of excretory functions could be seen. These results suggest that in maturity onset diabetes only a selective defect of the beta-cells exists, while in juvenile onset diabetes a destruction or reduction of beta-cells but an intact excretory function may be assumed.
