Male rats were orchiectomized(Orch) 2 weeks before they were treated with a single bolus injection of gonadotropin- releasing hormone (GnRH, 1 mk/kg of body dweight), hCT (3.4 ng/kg), or the combination of GnRH and hCT through a right jugular vein catheter. Blood sampoles (0.5 ml each time) were collected immeiately before (0-min) and then at 15, 30, 60,120 and 180 min after hormone infection. Plasma LH concentration was measured with a radioimmunoassay technique. Plasma calcium concentration was determined in an automatic analyzer. hCT singificantly diminished both the basal and GnRH-stimulated levels of pllasma LH without any relation to the reduced plasma levels of calcium. These results clearly demonstrated a plasma calcium- unrelated inhibitory effect of hCT on LH secretion. #2279# |
