实验表明，给动物腹腔注射通脉灵可显著改善垂体后叶素所致的微循环障碍（Ｐ＜０．００１），具有抑制体外血栓形成的作用（Ｐ＜０．０５），可明显降低血浆血栓素Ｂ２的水平，升高６－酮－前列腺素Ｆ１α含量。本品对动物急性毒性甚微，小鼠尾静脉注射最大耐受量大于８０ｇ／ｋｇ，腹腔注射最大耐受量大于１６０ｇ／ｋｇ。结果提示，通脉灵具有较好的活血化瘀及抗栓作用。
Experiments showed that intraperitoneal injection of Tongmailing to animals can significantly improve the microcirculatory disturbance caused by pituitrin (P<0.001), and has the effect of inhibiting thrombosis in vitro (P<0.05), and can significantly reduce plasma Thromboxane B2 levels increase 6-keto-prostaglandin F1 alpha content. This product has little acute toxicity to animals. The maximum tolerance of the mouse tail vein injection is greater than 80g/kg, and the maximum tolerance of the intraperitoneal injection is greater than 160g/kg. The results suggest that Tongmailing has good blood circulation and antithrombotic effects.
