国内一些单位应用现代血液动力学和微循环的理论、技术和方法进行实验研究的结果表明,各种血瘀证患者多有全身或局部血液动力学异常,经活血化瘀治疗,随病情缓解或好转,血液动力学异常或微循环障碍也得到改善或纠正。基于上述理论,我们进行了丹参降香注射液对犬门静脉压力的影响实验研究,现将初步结果报道如下。材料和方法将体重4.5～9kg 犬20只,分四组。甲组:丹参降香组;乙组:心得安组;丙组:组织胺 The results of experimental studies conducted by some domestic units using the theory, techniques and methods of modern hemodynamics and microcirculation have shown that many patients with blood stasis syndrome have systemic or local abnormal hemodynamics and are treated with blood circulation to relieve the disease. Improvements in hemodynamic abnormalities or microcirculatory disturbances have also been improved or corrected. Based on the above theory, we conducted an experimental study on the effect of Salvia miltiorrhiza injection on portal pressure in dogs. The preliminary results are reported below. Materials and Methods 20 dogs weighing 4.5 to 9 kg were divided into four groups. Group A: Salvia miltiorrhiza group; Group B: propranolol group; Group C: histamine
