Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .
