Abstract:
Objective To study the protective effect of hydrogen sulfide(H2S) on intestinal ischemia-reperfusion(I/R) injury so as to provide a new clinical treatment on I/R.Methods NaHS was taken as a donor of H2S.Forty Sprague-Dawley rats were divided into 5 groups with 8 rats in each group: sham operation group,I/R model group,tetram ethylpyrazine group,and NaHS 7 ?mol/kg and 14 ?mol/kg groups.The contents of superoxidase dismutase(SOD),malondialdehyde(MDA) and glutathione peroxidase(GSH-Px) in serum and intestinal tissue were measured,respectively.The intestinal mucosal injury and histological alteration were observed.Results The content of MDA within serum and intestinal tissue was significantly reduced and the activities of SOD and GSH-Px were significantly increased.H2S could obviously reduce the injury in intestinal mucosa and glands.Conclusion H2S possesses a protective effect on intestinal I/R injury in rats.
