KCSG exerts protective effects on intestinal barrier in intestinal manipulation (IM)-induced POI rat. A Representative H&E staining of the intestinal tissues from different treatment groups at ×200 magnification (scale bar = 100 µm). Black square, red arrow and blue arrow indicate focal edema, hemorrhage or necrosis of the villi as well as the inflammatory response with infiltration of macrophages and neutrophils, respectively. B Histological damage score for the intestinal tissues, n = 3. Data were presented as mean ± SEM. **P < 0.01, ***P < 0.001 vs. Model group
