应用￣（４５）Ｃａ跨膜流动测定技术研究钙拮抗剂ｖｅｒａｐａｍｉｌ、中药西红花（ＣｒｏｃｕｓＳａｔｉｖｕｓＬ．）、“地奥心血康”（ＤＡＸＸＫ）、川红花（ＣａｒｔｈａｍｕｓｔｉｎｃｔｏｒｉｕｓＬ．）及银杏叶（ＧｉｎｋｇｏｂｉｌｏｂａＬ．）等对大鼠主动脉￣（４５）Ｃａ跨膜内流的作用，以确定其对细胞膜Ｃａ￣（２＋）通道影响。实验结果表明：西红花、川红花、ＤＡＸＸＫ对平滑肌细胞膜上电压依赖Ｃａ￣（２＋）通道（ＰＤＣ）和受体操纵Ｃａ￣（２＋）通道（ＲＯＣ）都有阻滞作用，并以西红花的阻滞作用最强；而银杏叶对细胞膜Ｃａ￣（２＋）通道无阻滞作用。 The ~(45)Ca transmembrane flow assay was used to study the calcium antagonist verapamil, Crocus sativus L., DAXXK, Carthamustinctorius L. and Ginkgobiloba L. et al. The role of rat aortic ̄(45)Ca transmembrane influx to determine its effect on cell membrane Ca ̄(2+) channels. The experimental results show that the saffron, saffron, and DAXXK have a blocking effect on the voltage-dependent Ca 2+ channel (PDC) and receptor-operated Ca 2+ channel (ROC) on smooth muscle cell membranes, and they also use Western Red. The flower has the strongest retarding effect, while Ginkgo biloba leaves has no blocking effect on the cell membrane Ca 2+ channel.
