关于胃、十二指肠溃疡的发生机理,目前公认 Shay所提出的攻击因子和防御因子失衡的学说。本文实验证明,防御因子中以粘膜血流量的作用为最重要。本文用300克重雄性大白鼠造成30％面积的Ⅱ度烧伤,分2、 5、24、 72小时4组与对照组比较烧伤后胃粘膜应激程度。采用氙-133廓清法和氢廓清法测定粘膜血流;以硅胶制品 microfil(MV-122,MV-117) 和 mercox CL With regard to the pathogenesis of gastric and duodenal ulcers, Shay’s theory of imbalance between attack and defense factors is currently accepted. This experiment shows that the role of mucosal blood flow is the most important factor in defense factors. In this paper, 300 g male rats caused 30% of the area of ​​degree II burns, divided by 2, 5, 24, 72 hours and 4 groups compared with the control group after burns gastric mucosal stress. Determination of Mucosal Blood Flow by Deuterium-133 Dissociation Method and Hydrogen Clearance; Microfil (MV-122, MV-117) and Mercox CL on Silicone Products
