ABSTRACT
Objective: To investigate the effect of abstracted formula granule of Siwu drugs on the sex hormones and expressions of androgen receptor (AR)and estrogen receptor (ER) in bone marrow depressed mice. Methods: One hundred and eighty mice (90 male and 90 female) were randomly divided into 6 groups. The effects of the formula granule of Siwu on sex hormones and expressions of AR and ER were explored by SABC method in bone marrow of depressed mice. Results: For the male rats, the levels of androgen were increased in male of treatment groups compared with those of model groups (P＜0.05), and the levels of estrogen were decreased in male of treatment groups compared with those of model groups (P＜0.05).For the female rats, the levels of androgen were increased in female of treatment groups compared with those of model groups,but no significant differences (P＞0.05), and the levels of estrogen were decreased in femal of treatment groups compared with those of model groups (P＜0.05). There was a dose dependent manner between treatment groups. Conclusion: The results suggested that formula granule of Siwu drugs may play a role in the hematopoietic function to repair bone marrow depression by improving AR and the balance of estrogen / androgen in mice.
