Abstract
Purpose: We aimed to evaluate preventing effects of Glutamine (Gln) and β-hydroxy β-methylbutyrate (HMB) on methotrexate induced intestinal mucositisMaterials and Methods: Fifty Wistar albino rats were divided into 5 groups (G). Group G1 defined as control and G2 was the methotrexate (MTX) treated group. The group G3, G4 and G5 were MTX plus Gln, Mtx plus HMB, MTX plus Gln and HMB respectively. Distilled water was applied by gavage to the first 2 groups. Rat received intraperitoneal injections of MTX at the third day. On the fifth day intestinal tissue samples were obtained. Results: The G5 had similar results with the G1 group in the crypt length. According to Park scoring, G1 and G5 were both the highest scores among five study groups. When the tissue was inspected by caspase-3 coating, the lowest apoptotic rate is found in the G5. Conclusion: This research showed that the combination of Gln and HMB use is more effective then the separate use of both chemicals.
