PROLACTIN AND LUTEINIZING HORMONE RELEASE AFTER INTRAVENTRICULAR INJECTION OF HISTAMINE IN RATS

Abstract

Instituto de Investigaciones Cerebrales, Facultad de Ciencias Médicas, Universidad Nacional de Cuyo, Mendoza, Argentina(Received 12 August 1975)There is recent evidence that histamine is a normal constituent of the brain (Taylor, Gfeller & Snyder, 1972; Brownstein, Saavedra, Palkovitz & Axelrod, 1974) localized in nerve terminals and synaptic vesicles (Kataoka & De Robertis, 1967). As reported earlier, intracerebral injections of histamine induce ovulation (Sawyer, 1955) and progesterone secretion (Endröczi & Hilliard, 1965) in rabbits. Moreover histamine administration results in oviposition in fishes (Nambu & Hosokawa, 1971). These results suggest that histamine leads to increased gonadotrophic activity and thus its potential role as a neuroendocrine transmitter is being investigated. In the present preliminary investigation histamine was injected into the 3rd ventricle of adult (250–300 g body wt) male and female rats derived from a Holtzman stock.
