Figure 1: Effects of Opuntia humifusa (O. humifusa) aqueous extract on mucosal tissues in an ethanol-induced gastric ulcer model. (A) Images of gastric ulcers in the experimental groups. (B) Positive area was measured according to gastric lesion index as shown in Figure 2A and expressed as the intensity relative to control. Data are expressed as mean ± standard deviation (SD, n=5 animals/group). #P<0.05 and *P<0.01 compared with the normal control group and the ethanol-administered control group, respectively.
