Gastric mucosal blood flow(GMBF)by computed reflect-spectrophotometry and vascular permeability with Evans blue were measured in aspirin-induced AGML,and the relationship between gastric mucosal protection of L-SOD and vascular factor were analysed.

• 本文应用计算机反射分光光度法检测胃粘膜血流量（GMBF），利用Evans蓝观察血管通透性的改变，旨在探讨L－SOD的粘膜保护作用与血管因素之间关系。
