Fig. 5From: The protective effect of apelin against water-immersion and restraint stress-induced gastric damageMicroscopic appearance of gastric lesions. The rats were subjected to water-immersion and restraint stress (WIRS). F13A (150 µg/kg) was administered into the tail vein before the application of WIRS. After 6 h of WIRS, gastric lesions were examined histologically as described in “Materials and methods.” H&E staining (objective ×100). a Shows stomach specimen of control, b shows stomach specimen of WIRS group, c shows stomach specimen of F13A + WIRS and d shows stomach specimen of F13ABack to article page
