RÉSUMÉ
AIM:To study whether or not Huangshao Yinxue Granula(HYG) has the therapeutic effect on experimental psoriasis. METHODS: The mice were treated with HYG 3.125,6.25,12.5,and 25 g/kg(i.g.) for 1 or 2 weeks.We studied the effects of HYG on mitosis in mice vagina epithelium,the formation of granular layer in scale epidermis of mice tails,the changes in CD3, CD4 and CD8 factors of the serum in psoriasis-like mice and guinea-pigs. RESULTS: HYG could inhibit the mitosis in mice vagina epithelium,promote the formation of granular layer in scale epidermis of mice tails.It could also diminish the value of serum CD4/CD8 of mice to regulate abnormal immune reaction.HYG had evident therapeutic effect on the ear skin damaged with 5% propanolol in psoriasis-like guinea-pigs. CONCLUSION: HYG has therapeutic effect on psoriasis-like animal models.
