Abstract:
OBJECTIVETo observe the effects of Bushen Zhuyun Recipe (BZR) on protein expressions of estrogen receptor (ER), progesterone receptor (PR) and integrin alpha5 and beta3 in endometrium of rats at the implantation stage, for exploring the possible mechanism of the recipe in treating luteal phase defect (LPD) infertility.
METHODSFemale SD rats were randomly divided into 6 groups, the blank group, the model group, the WM group treated by Western medicine, and the three BZR groups treated by low-, middle- and high-dose BZR respectively. Rats were made to pregnancy and sacrificed at the implantation stage, their middle segment of uterus, about 1 cm in length was gotten for detecting the protein expressions by Western blot. Results The protein expressions of endometrial ER and PR were significantly higher, while those of integrin alpha5 and beta3 were significantly lower than those of the control group (P < 0.05). The protein expressions of endometrial ER and PR were significantly lower, but those of integrin alpha5 and integrin beta3 were higher in rats treated by middle- and high- dose BZR than those in model rats (P < 0.05).
CONCLUSIONBZR can raise the receptivity of rats' endometrium through down-regulating the expressions of ER, PR and increasing the protein expression of integrin alpha5 and beta3 in endometrium and thus to enhance the pregnant rate.
