我们在人脑动脉中进行了实验,以确定 5-羟色胺诱导的收缩过程中钙激活剂的来源。将尸检时获得的人类基底动脉环安装在充满生理盐溶液的器官浴中进行等长张力记录。在不含 Ca++ 的溶液中,对 5-羟色胺的收缩反应几乎被消除,并被尼莫地平显着抑制。在这两种情况下,对 5-羟色胺的反应抑制程度与使用 KCl 收缩血管时的抑制程度相当。这些实验表明,5-羟色胺通过增加膜对细胞外钙的通透性来介导人基底动脉平滑肌的收缩。
We performed experiments in human cerebral arteries to determine the source of activator calcium during contractions induced by 5-hydroxytryptamine. Rings of human basilar artery obtained at autopsy were mounted for isometric tension recording in organ baths filled with a physiological salt solution. Contractile responses to 5-hydroxytryptamine were virtually abolished in Ca++-free solution, and inhibited significantly by nimodipine. In both cases, the depression of the response to 5-hydroxytryptamine was comparable to that seen when KCl was used to contract the vessels. These experiments demonstrate that 5-hydroxytryptamine mediates contraction of the smooth muscle in human basilar artery by increasing membrane permeability to extracellular calcium.
