| Abstract: | The effects from one dose of PGE1 on the endocrine pancreatic secretions have been studied in rat. The dose is injected i.a. very near the pancreas in the abdominal aorta at the level of the caeliac artery. Glycemia, insulinemia and glucagonemia are studied after i.v. glucose injection in: a) normal rats; b) rats free from their endogenous rate of PGs by previous treatment with indomethacin i.p. and c) with an excessive rate of PGE1. The treatment with PGE1 produces an inhibitory effect on the insulinic response to glucose, as well as hyperglycemia and hyperglucagonemia. In the cases without the endogenous rat of PGs the insulinic secretion as a response to glucose is greatly improved. |
