The inhibitory effects of intracerebroventricular administration of saline on the plasma corticosterone response to ether stress in mice was reduced by Met-enkephalin and enhanced by Leu-enkephalin. When administered simultaneously the effects of the two peptides opposed each other. Met and Leu-enkephalin may subserve different physiological functions in the response of the hypothalamus-pituitary-adrenal system to stress.
脑室内注射生理盐水对小鼠血浆皮质酮对应激反应的抑制作用,在甲硫氨酸脑啡肽作用下减弱,而在亮氨酸脑啡肽作用下增强。当同时给予这两种肽时,它们的作用相互拮抗。甲硫氨酸脑啡肽和亮氨酸脑啡肽在应激时下丘脑-垂体-肾上腺系统反应中可能发挥不同的生理功能。
