Hypothalamic Biogenic Amines and the Regulation of Luteinizing Hormone Release in the Ratpends upon an elevated level of serum estrogen and a central circadian “clock” which is probably located in the suprachiasmatic nuclei of the hypothalamus (Coen and MacKinnon, 1976, 1977, 1980; Raisman and Brown-Grant, 1977). In 1976 there was also the first report clearly indicating that the majori

Dual Action of Norepinephrine in the Control of Gonadotropin Releasef LH release has been raised when it was found that infusion of NE into the third ventricle of ovariectomized (ovx) rats inhibited LH release (Gallo and Drouva, 1979). This chapter will briefly review the evidence of the dual role of NE in the regulation of LH release.

Recently two new peptides, dermorphin and sauvagine, have been isolated from the skin of the South American frog, .; they have been subsequently chemically id
