本期发表主要著作三篇,其内容简介如下:一、东京大学医学部和泉等报道“关于支气管收缩剂的作用及β-受体阻断剂的效果”一文,作者用摘出鼠(marmot)的气管切片,研究支气管收缩剂的作用及β-受体阻断剂Propranolol(Prop,心得安)的效果,认为鼠的气管片对Ach(乙酰胆碱)、Hist(组织胺).5—HT(五羟色胺)的收缩反应,随Prop 的浓度增加而增强,2×10~(-10)M～2×10~(-9)M 为最大。超此浓度后则减弱。三者对气管平滑肌收缩作用Hist≒5—
This issue is published in three major works, the contents of which are summarized as follows: First, the University of Tokyo Department of Medicine Stephen and other reports “on the role of bronchoconstrictor and β-blocker effect” article, the author with the removal of the trachea (marmot) The effects of bronchoconstrictor and propranolol (propranolol) were studied by sectioning the rat trachea against Ach (acetylcholine), Hist (histamine), and 5-HT (serotonin) The contractile response increased with the increase of Prop concentration, with the maximum of 2 × 10 ~ (-10) M ~ 2 × 10 ~ (-9) M. After this concentration is weakened. Three of the tracheal smooth muscle contraction Hist ≒ 5-
