Effects of antibiotics and DEX on intestinal injury in mice subjected to sham surgery or intestinal I/R. (A) Representative HE staining of the histological sections of the small intestine (original magnification ×100). (B) Quantitative analysis of intestinal injury. (C-H) Antibiotics and DEX treatments decreased the expression of inflammatory cytokines. Panels C and F, D and G, and E and H show the levels of IL-6, IL-1β, and TNF-α in tissue and plasma, respectively. *, P<0.05 compared to the control group; **, P<0.01 compared to the control group; #, P<0.05 compared to the I/R group; ##, P<0.01 compared to the I/R group. Con, control; I/R, ischemia-reperfusion; DEX, dexmedetomidine; ABX, antibiotics; IL, interleukin; TNF, tumor necrosis factor; HE, hematoxylin and eosin.
