Abstract
We investigated the effect of blocking endogenous LH-RH, by injection of anti LH-RH sera, on serum prolactin levels previously elevated by treatment with haloperidol for 5 days. An acute intravenous injection of rabbit anti-LH-RH serum significantly reduced serum LH levels and blocked the hyperprolactinemia induced by haloperidol. In another group of rats, sheep anti-LH-RH serum induced a significant decrease of serum LH and also lowered serum prolactin levels previously elevated by haloperidol. In ovariectomized rats, sheep anti-LH-RH serum markedly reduced serum LH levels and also decreased serum prolactin elevated by the pretreatment with haloperidol. It is concluded that the serum LH levels and also decreased serum prolactin elevated by the pretreatment with haloperidol. It is concluded that the blocking of endogenous LH-RH action resulted in a decreased release of prolactin in response to stimuli like haloperidol. These results support the possible existence of a paracrine interaction between the pituitary gonadotrophs and lactotrophs.
