Abstract:
AIM: To investigate the effect of autophagy on cell ferroptosis in intestinal ischemia-reperfusion injury. METHODS: Twenty-four SPF grade Wistar rats weighing 200-220 g were divided into 4 groups (n = 6): sham operation group (sham group), ischemia group (I group), ischemia-reperfusion group (I/R group),and ischemia-reperfusion + autophagy inhibitor group (I/R + 3-MA group). The ischemia model was established by clamping the superior mesenteric artery for 1 hour, and the intestinal ischemia-reperfusion injury model was established by reperfusion for 2 hours. HE staining was used to observe the pathological changes of intestinal mucosa and Chiu score under light microscope. Fe
