Abstract/OtherAbstract:
The effect of essential fatty acid deficiency and nitrosomethylurea treatment on postnatal levels of pancreatic gamma-glutamyltranspeptidase was studied. A significant increase of gamma-glutamyltranspeptidase activity and changes in fatty acid composition were observed in essential fatty acid deficient rats, from the 14th day of life on. Pancreatic gamma-glutamyltranspeptidase of nitrosomethylurea injected rats in essential fatty acid deficiency and controls was significantly diminished at the 30th day, with no significant differences in both nutritional conditions. The results indicated: 1. Concomitant changes in gamma-glutamyltranspeptidase activity and fatty acid composition of rat pancreas in essential fatty acid deficiency, 2. A significant reduction of pancreatic gamma-glutamyltranspeptidase activity following a single intraperitoneal injection of nitrosomethylurea at day one of life and 3. No interacting effects of essential fatty acid deficiency and nitrosomethylurea on gamma-glutamyltranspeptidase activity of rat pancreas.
