Vitamin E Prevents Cold Wrap Restraint Stress-Induced Intestinal Fluid Transport Alterations in Rats
Psychological stress may alter gastrointestinal absorptive function by increasing the quantity of intestinal free radicals or by lowering endogenous intestinal free radical scavenging capacity. Vitamin E has been shown to be a potent endogenous antioxidant and free radical scavenger under both physiological and pathological conditions. The purpose of this study was to determine whether cold wrap restraint stress altered in vivo intestinal fluid absorption in rats, and whether vitamin E administration prior to the induction of cold wrap restraint stress could prevent such changes in intestinal secretion. Jejunal, ileal and colonic fluid and electrolyte transport rates were measured in vivo using an isolated loop technique. Cold wrap restraint stress reduced in vivo fluid absorption in the ileum and colon, but not in the jejunum. Administration of vitamin E prior to the cold wrap restraint stress procedure completely prevented this alteration of ileal and colonic fluid absorption.
