测定了冷习服及未习服雄性Ｗｉｓｔａｒ大鼠冻伤前后血中血管内皮细胞数。结果表明，冷习服（２～６℃，４周）可使大鼠循环血中血管内皮细胞（ＣＥＣ）数非常显著地高于正常大鼠（２０±２℃），冻伤前后冷习服冻伤组ＣＥＣ无明显差别；未冷习服大鼠冻伤后ＣＥＣ非常明显的增加；冻后４ｈ冷习服冻伤组ＣＥＣ数明显低于未冷习服冻伤组。结果提示，冷习服后大鼠血管内皮细胞代谢旺盛、更新加速，且其抗冷损伤的能力增加。

The number of blood vascular endothelial cells before and after frostbite in cold acclimated and uninhabited male Wistar rats were determined. The results showed that cold acclimation (2 ~ 6 ℃, 4 weeks) can make the number of circulating vascular endothelial cells (CEC) in rats significantly higher than normal rats (20 ± 2 ℃), frostbite before and after cold acclimatization frostbite Group CEC no significant difference; uncooled accustomed to cold injury in rats after CEC increased significantly; cold 4h cold frostbite CEC number was significantly lower than the group without cold acclimation frostbite. The results suggest that the rat vascular endothelial cells after cold acclimation metabolism is exuberant, the update accelerated, and its ability to resist cold injury increased.
