本文现察了兔足重度冻伤后血液流变性的改变以及蝮蛇抗栓酶治疗对这些改变的影响。实验将家兔双后足置－２５℃９５％乙醇中造成重度冻伤．冻肢融化后给予 ０．２５Ｕ／ｋｇ体重加入 ２０ｍｌ／ｋｇ体重生理盐术中静脉点滴治疗。结果显 示冻伤后家兔血液粘度、红细胞数、红细胞比积及红细胞沉降率均增加，表明冻伤 引起机体血流变性质改变，血流变慢，而经蝮蛇抗栓酶治疗后，上述改变均呈不同程度的恢复，这对改善冻伤组织血液循环障碍的病变过程具有重要作用。
This article examines the changes in hemorheology after severe frostbite in rabbits and the effects of antithrombin therapy on these changes. The rabbits were placed in -25°C 95% ethanol to cause severe frostbite. After the frozen limb was thawed, 0.25 U/kg body weight was added to the 20 ml/kg body weight of saline during the intravenous drip. The results showed that the blood viscosity, red blood cell count, hematocrit, and erythrocyte sedimentation rate increased after frostbite in rabbits, indicating that the body’s blood rheological properties were changed due to frostbite and the blood flow became slower. The above changes were observed after treatment with Anophthalmia antithrombus enzyme. It has been restored to varying degrees, which has an important role in improving the pathological process of frostbite tissue blood circulation disorders.
