摘　　要：采用测定冻伤兔足皮肤温度和肌糖元含量的方法，间接观察在缺氧条件下兔足重度冻伤血液循环和肌肉能量代谢的改变。实验结果表明：平原冻伤组、急性缺氧冻伤组、缺氧两周冻伤组冻足皮肤温度和肌糖元含量均明显降低。经４０℃０．１％的洗必泰液多次温浸治疗冻伤兔足，平原冻伤组和急性缺氧冻伤组的治疗足皮肤温度和肌糖元含量均高于未治疗足，无明显差异，提示在此种条件下冻足的血液循环障碍可能更加严重。Effects of exposure to acute hypoxia and hypoxia for 2 weeks on the skin temperature and content of glycogen of frostbitten feet in rabbits were observed. The results showed that the skin temperatures and content of glycogen were decreased in frostbite at normoxia (FN) group, frostbite during acute hypoxia (FAH) group and frostbite hypoxia for 2 weeks (FH 2w) group. After treatment with warm chlorhexidine immersion the skin temperature and glycogen content in treated feet of FN and FAH group were increased, as compared with untreated feet. However, there was no difference between treated and untreated feet in FH 2w group, suggesting that there may be severe disturbance of blood circulation on frostbitten feet under this condition.
