动脉血CO_2分压(PaCO_2),O_2分压(PaO)2)和 pH (apH)值不同能引起脑血管舒缩活动改变早已为人们熟知,但是它们的作用部位所在仍然是一个谜。有的作者认为,脑小动脉的平滑肌纤维细胞内 pH 是管理脑血管舒缩活动的最后总通路。作者用测定猫的脑组织 PaO_2、PaCO_2、apH 和脑血流(CBF)的方法研究脑血管舒缩活动的化学控制机理。试验在31只猫身上进行并在下 Arterial blood pressure (PaCO 2), O 2 partial pressure (PaO) 2) and pH (apH) values ​​can cause changes in cerebral vasomotor activity already well known, but their role in the site is still a mystery. Some authors believe that the smooth muscle fiber intracellular pH of the cerebral arterioles is the final general pathway for managing cerebral vasomotor activity. The authors used the method of measuring PaO 2, PaCO 2, apH and cerebral blood flow (CBF) in brain tissue of cats to study the chemical control mechanism of cerebral vasomotor activity. The experiment was conducted on 31 cats and was below
