摘　　要：目的探究阿胶对环磷酰胺（cTx）所致血虚证C57BL／6小鼠毛发生长及质量改善的作用。方法将CTX所致血虚证模型C57BL／6小鼠分为阿胶给药组（高、中、低剂量组）和模型对照组，另设空白对照组，分别灌胃相应剂量的阿胶溶液和生理盐水，连续20d；首次给药后0d，12d和20d，测定小鼠新生毛发的长度、氨基酸含量、毛囊数量及血液学参数，并用电子显微镜观察毛发的微观形态。结果阿胶给药组及空白对照组白细胞总数、淋巴细胞含量和单核细胞含量均高于模型对照组；中、高剂量组小鼠毛发中氨基酸含量高于模型对照组；首次给药后20d，小鼠新生毛发长度及浓密程度：空白对照组〉阿胶给药组（高、中、低剂量组）〉模型对照组：电镜观察，各组小鼠新生毛发直径存在明显差异：空白对照组〉高剂量组〉中、低剂量组〉模型对照组；小鼠新生毛囊数量：空白对照组〉阿胶给药组〉模型对照组。结论阿胶可以升高CTX所致血虚证模型C57BL／6小鼠体内白细胞数量，促进C57BL／6贫血小鼠皮肤新生毛囊的形成，促进毛发生长，增加毛发中氨基酸含量，起到改善新生毛发质量的作用。Objective To explore the effects of colla corii asini on the growth and quality improve- ment of hair in mice of anemia caused by cyclophosphamide. Methods The mice model of anemia was established by ip cyclophosphamide. C57BL/6 mice were divided into five groups （the high dose group, the medium group and the low dose group, the model control group and the blank control group）, and the different dose of colla corii asini or physiological saline were respectively administrated for 20 days by gavage. The number of hair follicles, the various content of blood cell, the length and the amino acid content of the hair in mice were determined, and the microstructure of hair were observed by the electron microscope at the 0 day, 12 days and 20 days after the first treatment. Results The contents of white blood cells, lymphocytes and monocytes in all colla corii asini groups and the blank control group, were higher than that of the model control group. The amino acids in the new hair of medium and high dose group mice were higher than that of the model control group. At the 20 days after the first treatment, the length and thickness of new hair in mice of all colla corii asini groups （the high, medium and low dose group） was more than that of the model control group, and was less than that of the blank control group, but there was no significant difference among the hair length （P〉0.05）. Scanning electron microscope （SEM） images showed there were significant differences in new hair diameter among different groups, the diameter of all colla corii asini groups was more than that of the model control group, and was less than that of the blank control group. And the diameter of the high dose group was more than that of the medium and the low dose group. The number of hair follicle of all colla corii asini groups was more than that of the model control group, and was less than that of the blank control group. Conclusion The colla corii asini could increase the number of white blood cells in C57BL/6 mice of ane
