实验比較了当归,丹参,鸡血屯三药对蟾蜍离体及在体心脏的作用,結果皆呈抑制,以当归作用最强,丹参次之,鸡血屯又次之。大剂量当归、丹参对在体蟾蜍心脏能引起房室传导阻滞。丹参能舒张蟾蜍血管,当归、鸡血屯則能收縮其血管,后二者作用强度近似。对离体兔耳血管,鸡血屯呈收縮作用,当归、丹参为舒张作用,当归作用强于丹参。三药皆使家兔血压下降,作用以当归最强,鸡血屯次之,丹参又次之,并皆使犬血压下降,作用以丹参最强,鸡血屯次之,当归又次之。 Experiments compared the effects of Angelica, Salvia miltiorrhiza, and Jixuetun on the isolated and in vivo heart. The results were all inhibited. Angelica had the strongest effect, followed by Salvia miltiorrhiza, followed by Jixuetun. Large doses of angelica and salvia miltiorrhiza can cause atrioventricular block in the heart of the body. Salvia miltiorrhiza can dilate blood vessels, while angelica and chicken blood can shrink their blood vessels, and the latter two have similar strengths. In isolated rabbit ear veins, Jixuetun showed a contraction effect. Angelica and Salvia miltiorrhiza were used for relaxation. Angelica was stronger than Salvia miltiorrhiza. The three drugs all reduced the rabbit’s blood pressure, and the effect was the strongest in the angelica, followed by the chicken blood, followed by the salvia miltiorrhiza, and both reduced the blood pressure of the dogs. The effect of the salvia miltiorrhiza was the strongest, the chicken blood was the second, and the angelica was the second.
