    Abstract:
    BACKGROUND: Arginine is a dibasic amino acid with significant metabolic and immunologic, effects especially in trauma and stress situations. Arginine supplementation has been shown to promote wound healing and improve immune system. We designed a study to evaluate the effects of supplemental dietary arginine on intestinal mucosal recovery and bacterial translocation and bacterial clearance after induction of radiation injury in rats. METHODS: Twenty-one male Sprague-Dawley rats were subjected to a single dose of 1100 rads of abdominal X radiation. Rats were divided into three groups; the first group received diet enriched with 2% arginine, the second group with 4% arginine, and the third group with isonitrogenous 4% glycine. Rats were sacrificed 7 days after the radiation. Blood was drawn for arginine levels and mesenteric lymph nodes were harvested for quantitative aerobic and anaerobic cultures. Segments of ileum and jejunum were evaluated for villous height, number of villi per centimeter of intestine, and the number of mucous cells per villous. RESULTS AND CONCLUSIONS: Arginine is absorbed reliably from the gut following oral administration. Dietary 4% arginine supplementation enhanced bacterial clearance from mesenteric lymph nodes compared to 2% arginine and 4% glycine supplemented diet following radiation enteritis in rats. Four percent arginine resulted in clear improvement in intestinal mucosal recovery when compared to 2% arginine and 4% glycine after abdominal irradiation in rats.
