[Pulsatile secretion of gonadotropins and prolactin and response to luliberin in female rats after injection of galanin into the third cerebral ventricle].

Galanin injection in a dose 200 ng/2 microliters into the third brain ventricle of ovariectomized Sprague-Dawley rats increased pulsatile release of LH and prolactin but did not influence FSH release. Gonadotropin response to LHRH was unchanged. In ovariectomized estrogen-primed rats (50 micrograms estradiol benzoate 73 h prior to the experiment) galanin stimulating effect on LH secretion was slightly manifest and prolactin and FSH release did not change at all.
