In the present study, the effect of dietary fish oil, a highly unsaturated fat source, on the intestinal mucosa before and after proximal small bowel resection in rats was studied. Forty Wistar rats were fed defined diets containing fish oil (experimental group) or corn oil (control group). After 2 weeks, animals underwent a 50% proximal small bowel resection. Mucosal disaccharidases, alkaline phosphatase, aminopeptidase, protein, DNA, and TBARs levels were assessed in samples immediately before and 6 and 12 days after surgery. Disaccharidase activities were reduced in the ileal mucosa from rats in the fish oil-fed group compared to the control group before and 12 days after surgery. The other parameters showed no significant differences. The results indicate that fish oil (omega-3 fatty acids) alters the functional parameters of the normal intestinal mucosa and after intestinal resection compared to omega-6 polyunsaturated fatty acids, suggesting that caution should be taken to use omega-3 fatty acids as adjuvants in the adaptive process after resection.Downloads
