Abstract

In order to induce a hypophysetrophic response and to evaluate the maximum number of noradrenergic receptors (NA-receptors) in anterior pituitary gland (AP), 17 {beta}-estradiol (E {sub 2}) steroid was used in immature female rats (21--25 days old). A significant increment in AP weight was detected 24 hs after E {sub 2} administration. In addition, the number of NA-receptor present. In the gland of rats treated with E {sub 2}, decreased from 4 to 48 hrs, indicating that the NA system may play an important role on AP endocrine function. (author).
