Abstract
Abnormal endocrine profile, especially in the enteropancreatic axis, was described in rats with malnutrition caused by malabsorption after total gastrectomy. Insulin, substance P and motilin concentrations at the fasting condition were significantly elevated in malnutritious rats after total gastrectomy when compared to those in control rats. A significant elevation of pancreatic glucagon and motilin was noted after intraduodenal fat administration in malnutritious rats. These data suggest that these peptides of many humoral factors may thus cause abnormal enteropancreatic axis and consequent malnutrition.
