The stimulatory effect of cholecystokinin implanted in the medial preoptic area on luteinizing hormone secretion in the ovariectomized estrogen-primed rat.

Abstract

The effect of implantation of cholecystokinin(CCK)-8 into the medial preoptic area (MPO) through the chronically implanted guide cannula on the release of LH was examined in the ovariectomized estradiol-primed rat. An inner cannula with CCK-8 at the tip, as well as an empty inner cannula as the control, was implanted into the MPO at 12.00 h. Blood samples… (More)
