Abstract:
Objective To observe the effect of resveratrol on intestinal ischemia reperfusion(IIR)inju-ry and its correlation with ferroptosis.Methods The mice IIR injury model was constructed.The mice were divided into the sham operation group(group S),IIR injury group(group D),IIR injury+resveratrol group(group R),IIR injury+ferroptosis inducer group(group F),IIR injury treatment+resveratrol+ferropto-sis inducer group(group R+F).The various groups adopted different drug doses and methods.The intestinal tissue sections were taken for performing the HE staining and the pathological changes were observed by the light microscope.ELISA was used to detect the levels of malondialdehyde(MDA),ferrous ion(Fe2+),gluta-thione(GSH)and super oxide dismutase(SOD).Western blot was used to detect the expression levels of glu-tathione peroxidase 4(GPX4)and acyl-coasynthetasling-chain family member 4(ACSL4)protein.Results Com-pared with the group S,the small intestine tissue damage in the group D,R,F and R+F was aggravated,the Chiu's score,MDA and Fe2+level s were increased,GSH and SOD levels were decreased(P＜0.05),the AC-SL4 protein expression was up-regulated,GPX4 protein expression was down-regulated,and the differences were statistically significant(P＜0.05).Compared with the group D,the small intestine tissue in the group R appeared subapical villous injury,Chiu's score,MDA and Fe2+levels were decreased,the GSH and SOD levels were increased,the ACSL4 protein expression was down-regulated and GPX4 protein expression was up-regu-lated,and the differences were statistically significant(P＜0.05);the small intestine tissue in the group F ap-peared villi fall off accompanied by bleeding and ulcer formation,Chiu's score,MDA level and Fe2+level were increased,GSH and SOD levels were decreased,ACSL4 protein expression level was up-regulated,GPX4 pro-tein expression was down-regulated,and the differences were statistically significant(P＜0.05).Compared with the R group,the small intestine tissue in the R+F group appeared a large number of villi and lamina pro-pria,which were damaged and fell off,Chiu's score,MDA and Fe2+levels were increased,GSH and SOD lev-els were decreased,ACSL4 protein expression was up-regulated and GPX4 protein expression was down-regu-lated,and the differences were statistically significant(P＜0.05).Conclusion Resveratrol may alleviate intes-tinal injury caused by IIR through antioxidation action and inhibiting ferroptosis.
