实验观察冻伤对低氧习服家兔组织氧耗量和局部微循环灌流量的影响以及治疗后的改变。实验选用健康雄性大耳的家兔随机分为正常组、冻伤对照组和冻伤治疗组。除正常组以外 ,其它组每日间断低氧 4ｈ ,持续 2周后按2 5 / 2 0重度冻伤模型冷冻。冻后连续 7天内 ,治疗组家兔给予药物 The effects of frostbite on tissue oxygen consumption and local microcirculation perfusion of hypoxic-accustomed rabbits and the changes after treatment were observed. Experimental selection of healthy male large ears of rabbits were randomly divided into normal group, frostbite control group and frostbite treatment group. In addition to the normal group, the other groups intermittent hypoxia 4h intermittently, continued 2 weeks after 2 5/2 0 severe frostbite model frozen. Within 7 days after freezing, rabbits in the treatment group were given drugs
