高原地区严重烧伤具有不同于平原地区的病理生理特点,在缺氧性损害的基础上加上再灌注损伤可造成机体各器官组织损伤加重。作者以海拔3840m(甘肃马晗山)和1517m(兰州)为背景,以大鼠为研究对象,建立大鼠严重烧伤后即时复苏与延迟复苏模型,检测不同海拔高度肠黏膜组织匀浆液中丙 Severe burns on the plateau have different pathophysiological characteristics from the plain areas. On the basis of the hypoxic damage, reperfusion injury can cause the damage of various organ tissues. The author took the rats as the research object at the altitude of 3840m (Mahan Mountain in Gansu) and 1517m (Lanzhou) as the research object to establish a model of immediate resuscitation and delayed resuscitation after severe burns in rats, and to detect the changes of intestinal mucosal homogenate in different altitude
