Effects of an olive oil-enriched diet on plasma GLP-1 concentration and intestinal content, plasma insulin concentration, and glucose tolerance in normal rats.

The present study aims mainly at measuring, in normal rats, the GLP-1 response to oral intake of an olive oil-enriched diet (OO), and at assessing the long-term effects of such a diet on the GLP-1 content of the intestinal tract, as well as the plasma D-glucose, insulin, and GLP-1 pattern during an oral glucose tolerance test. In meal-trained rats, the mean increment in plasma GLP-1 concentration at min 10 and 20 was 1.39 +/- 0.

Plasma D-glucose, D-fructose and insulin responses after oral administration of D-glucose, D-fructose and sucrose to normal rats.

Objective: To assess whether oral D-fructose modifies the plasma D-glucose and insulin responses to oral D-glucose administration in normal rats.

Design: Oral D-glucose (1.7, 3.

Stimulation of proinsulin biosynthesis by K+ in rat pancreatic islets.

Glucose-stimulated proinsulin biosynthesis is regulated mainly at the translational level. This study aims at investigating the possible role of the B-cell K+ content in such a process. In order to increase the islet cells K+ content, rat pancreatic islets exposed to a low D-glucose concentration (e.
