Abstract:
Objective To explore the possible functional mechanism of Er-xian Decoction and its component herbs on the expression of extrogen receptor(ER) in adrenal development rats.Methods Fifty-four development female SD rats were randomly divided into nine groups:normal control group(A),positive control group(B),Er-xian Decoction group(C),Herba Epimedii group(D),Rhizoma Curculiginis group(E),Radix Morindae Officinalis group(F),Radix Angelicae Sinensis group(G),Cortex Phellodendri group(H),Rhizoma Anemarrhenae group(I).After the rats were administrated for six days,serum were got to measure testosterone(T).Bilateral adrenal gland was weighed and embedded by paraffin.Mean optical density(MOD) were studied by the immunohistochemical method and image analyzing system.Results The adrenal coefficient was increased in group B and C,and the level of T was decreased in group C,D,E and I.ER? was mainly observed in the cytoplasm of zona glomerulosa and zona fasciculate.MOD in group C was increased while declined in group B.ER? was mainly observed in nucleus of zona glomerulosa and zona fasciculate.MOD in group C,D,E and I was less than group B.Conclusion Er-xian Decoction and its component herbs of warming Shen(Herba Epimedii,Rhizoma Curculiginis) and nourishing Yin(Rhizoma Anemarrhenae) play a phytoestrogen role by influencing the expression of ER? and ER ? in the adrenal cortex.
