Leu-enkephalin (LE) induced mainly a constriction of pial arterioles, diameter of the venules did not change. The effect of the LE involved preservation of the cerebral blood flow and that in microvessels, constriction of some arterioles and reduced dilatation against the background of decreased arterial pressure, bradycardia, increased lymphatic flow and survival of the animals during first hours of occlusion of common carotid arteries.
亮氨酸脑啡肽（LE）主要引起软脑膜小动脉收缩，小静脉直径不变。LE的作用包括在颈总动脉闭塞的最初几个小时内维持脑血流量以及微血管内的血流量，使一些小动脉收缩，并在动脉压降低、心动过缓、淋巴液流量增加和动物存活的背景下减少血管扩张。
