Ovarian steroid modulation of norepinephrine action on luteinizing hormone release. Analogous effects in male and female rats.

abstract：:Lactotrophs, gonadotrophs, thyrotrophs and somatotrophs of the rat anterior pituitary (AP) express 68-kDa neurofilaments (NF68) and other neuronal markers. NF68 expression in the AP appears to be estrogen-dependent, but its significance is unknown. The aims of this work were: (1) to establish the expression pattern of...
