Results Punctiform erosion, hemorrhage were observed by nake eyes in each groups. Epithelium cellular necrosis, defluxion, neutrophil being dominant in propria lamina and intact glandular were observed with microscopy. The erosion became severe with the successive stimulate of ethanol. There is no difference between distillate spirit and sodium chloride rats in Guth in 7th day, but Guth in distillate spirit rats was higher than that in sodium chloride rats in 30th day. PGE2, TGF-α contents in gastric mucosa of treated group increased significangly compared with control group. PGE2 showed no difference between each group in 7th and 30th day; TGF-α in gastric mucosa of distillate spirit and sodium chloride rats decreased after 1 month.
