摘 要 ：脑脉通和丹参都可抑制CaCl₂和KCl诱发的兔基底动脉的收缩,对CaCl₂量—效曲线呈非特异性拮抗作用。脑脉通对高K~+去极化所致肌环收缩的拮抗作用较丹参强。脑脉通对大鼠门静脉条的自律性收缩有轻度抑制作用,而丹参则无。

Abstract:Both Naomaitong and single salvia miltiorrhiza inhibit the contraction of rabbit basilar artery rings evoked by CaCl₂ and KC1 and have nonspecific antagonism against the quantityeffect curve of CaCl₂. Naomaitong and single salvia miltiorrhiza atso inhibit the contraction of rabbit basilar artery rings evoked by KC1. Clearly the inhibitory function of the former is greater than that of the latter. But on the myogenic activity of portalvein strips in rats Naomaitong has light inhibitive effect while salvia miltiorrhiza has not.
