[Effects of Huoxue Bushen Mixture on skin blood vessel neogenesis and vascular endothelial growth factor expression in hair follicle of C57BL/6 mice].
OBJECTIVE
To investigate the possible stimulating mechanism of Huoxue Bushen Mixture (HXBSM), a traditional Chinese compound medicine, on hair growth of mice via measuring the variance of skin blood vessel neogenesis and vascular endothelial growth factor (VEGF) expression in the hair follicle.


METHODS
Hot rosin and paraffin mixture depilation were used to induce C57BL/6 mice hair follicle to enter from telogen into anagen. Ninety C57BL/6 mice were divided into 3 groups randomly: HXBSM group, Yangxue Shengfa Capsule (YXSFC, another traditional Chinese compound medicine) group and untreated group. The mice were fed with corresponding drugs after modeling. The hair growth of the mice was observed every day. Every ten mice out of each group were executed respectively at day 4, 11 and day 17. Skin blood vessel neogenesis was counted through pathological section and VEGF expression in the hair follicle was measured via immunohistochemical method.


RESULTS
The number of local blood vessel neogenisis in the HXBSM group observed was larger than that in the untreated group at day 4 (P<0.05); and evidently larger than that in the YXSFC group and the untreated group at day 11 (P<0.05). The expression of VEGF in the hair follicle was distinctively higher than that in the YXSFC group and the untreated group at day 11 and day 17 (P<0.05).


CONCLUSIONS
HXBSM up-regulates VEGF expression to accelerate blood vessel neogenesis and hair growth.
