Abstract :Objectives: The aim of this study was to determine the effects of whey proteins on methotrexate insert ignore into journalissuearticles values(MTX);-induced brain and small intestine damage. Materials and Methods: 30 Sprague Dawley rats insert ignore into journalissuearticles values(200-300 g); were divided into four groups: Control, control + whey, MTX, and MTX+whey. MTX was administered at 20 mg/kg insert ignore into journalissuearticles values(single dose); intraperitoneally to the MTX group rats, and 2 mg/kg of whey protein were administered by oral gavage for 10 days to the whey groups. Lipid peroxidation, glutathione, and nitric oxide insert ignore into journalissuearticles values(NO); levels, as well as glutathione-S-transferase and superoxide dismutase activities were measured in the brain and small intestine. SDS-polyacrylamide gel electrophoresis of the brain and intestine tissues were also carried out. Results: While MTX treatment caused oxidative damage in the brain and small intestine, whey protein administration ameliorated MTX-induced oxidative stress. MTX administration did not change the brain’s NO level, while an increase in intestinal NO level was detected. Conclusion: MTX induced oxidative stress in the brain and small intestine changed the protein metabolism in these tissues regardless of reduced food intake. Consecutive 10-day administration of whey proteins has shown its therapeutic effect on MTX-induced brain and small intestine oxidative damage.
