title: Effect of atrial natriuretic peptide on acetylcholine-induced release of corticotropin-releasing factor from rat hypothalamus in vitro.
abstract: Effect of rat atrial natriuretic peptide (rANP) on acetylcholine-induced release of corticotropin-releasing factor (CRF) from the rat hypothalamus was studied in vitro using perifusion method. Perifused acetylcholine at 100 and 1000 ng/ml evoked significant CRF release, whereas norepinephrine at 10, 100 and 1000 ng/ml did not show a definite effect on CRF release. Continuous administration of alpha-rANP(1-28) (20ng/ml) inhibited the acetylcholine (100ng/ml)-induced CRF release. It is likely that ANP is involved in the regulation of CRF release.
