Abstract
The hypothalamic secretion of epinephrine (EPI), norepinephrine (NE), and dopamine (DA) into hypophysial portal blood was studied in adrenalectomized rats subjected to heat stress. Portal plasma EPI levels were increased 3-fold by heat stress whereas portal plasma concentrations of NE and DA were not altered by stress. These data suggest that EPI of hypothalamic origin may be involved directly in the modulation of anterior pituitary secretion during stress.
摘要
研究了热应激下肾上腺切除大鼠下丘脑分泌肾上腺素（EPI）、去甲肾上腺素（NE）和多巴胺（DA）进入垂体门脉血液的情况。热应激使门脉血浆EPI水平增加了3倍，而应激并未改变门脉血浆中NE和DA的浓度。这些数据表明，下丘脑来源的EPI可能直接参与应激期间垂体前叶分泌的调节。
