Galanin (GAL) is widely distributed in the peripheral and the central nervous systems. In the brain, the highest GAL concentrations are observed within the hypothalamus and, particularly, in nerve terminals of the median eminence. This location, as well as GAL actions on prolactin, growth hormone, luteinizing hormone (LH), and LH-releasing hormone (LHRH)(More)
Virgin proestrous rats were acutely treated with 2 doses of morphine sulfate (MS) (5-8 and 40 mg/kg BW) or naloxone HCl (NH) (10 mg/kg BW) co-administered with the high dose of MS, and the pituitary portal plasma concentrations of gonadotropin releasing hormone (GnRH) were compared with those of untreated proestrous (PE) and diestrous (DE) control animals.(More)
The present studies were designed to determine whether an ultrashort loop feedback mechanism is involved in the regulation of LHRH secretion. Daily administration of a highly potent LHRH agonist (LHRH-AGO; [D-Ala6,Des-Gly10] LHRH ethylamide) immediately after orchidectomy (ORDX) significantly attenuated the rise of plasma LH from days 2 through 10 after(More)
Acute ethanol (EtOH) treatment resulted in a significant decline in hypophyseal portal plasma levels of luteinizing hormone-releasing hormone (LH-RH) in orchidectomized rats. This was accompanied by a similar decrement in circulating luteinizing hormone (LH) without, however, modifying plasma follicle-stimulating hormone (FSH) levels at time when peak blood(More)
There is a need for a satellite communications receiver that can perform simultaneous multi-channel processing of single channel per carrier (SCPC) signals originating from various small (mobile or fixed) earth stations. The number of ground users can be as many as 1000. Conventional techniques of simultaneously processing these signals is by employing as(More)
