Method : three kinds of mice ulcer models induced by binding and water immersion - restraint stress ( wrs ) , alcohol and reserpine respectively ; the extent of gastric mucosal injury was evaluated grossly and histologically 方法采用束缚水浸、乙醇、利血平诱导致小鼠急性胃粘膜损伤，以溃疡指数及胃粘膜组织学改变为指标，观察溃疡康对不同实验性胃溃疡小鼠胃粘膜损伤的影响。
Helicobacter pylori is an important bacterial pathogen that causes chronic active gastritis and is associated with gastroduodenal ulcer disease , adenocarcinoma of the distal stomach , and gastric lymphoma in humans 幽门螺杆菌( helicobacterpylori ， h pylori )是导致人类发生慢性活动性胃炎、消化性溃疡的主要病原菌，并且与胃腺癌、胃粘膜相关淋巴组织淋巴癌的发生也密切相关。
The orange red 、 shiny surface of normal mucosa was replaced with pale one ; atrophic mucosa was thinned , limit of which was signicant to normal mucosa ; atrophic region revealed more readliy the submucosal vasculature , due to thinner mucosa 胃镜，正常胃粘膜的橘红色色泽消失，代之以灰白色；萎缩胃粘膜变薄，与周围的正常胃粘膜界限明显；萎缩处因粘膜变薄，粘膜下血管分支清晰可见。
