[Effects of recipe for invigorating kidney on expression of estrogen receptors in ovariectomized rats].

OBJECTIVE To observe the effects of recipe for invigorating kidney on expression of estrogen receptors in ovariectomized rats. METHODS The rats, which were given high-cholesterol diet after ovariectomy, were chosen as experimental subjects. After fed kidney-invigorating recipe for 16 weeks, the rats were killed and the levels of serum lipid and estradiol of these rats were examined. The expressions of estrogen receptor alpha and beta mRNAs in aorta, pituitary gland and hypothalamus, and the affinity of estrogen receptor-ligand were also detected. RESULTS The kidney-invigorating recipe could increase the expression levels of estrogen receptor alpha and beta mRNAs in different parts such as aorta, pituitary gland and hypothalamus, and enhance the affinity of estrogen receptor-ligands. CONCLUSION The recipe for invigorating kidney may meliorate atherosclerosis in ovariectomized rats by regulating the estrogen receptors.
