有效成分组替代舒胸片原复方可行性的药效学探讨

目的:"在中药复方有效成分组"概念的指导下,比较舒胸片(三七、红花、川芎)及其有效成分组(SECG)在抗炎、镇痛、抗凝血、抗血栓和心肌保护方面的差异。方法:通过小鼠角叉菜胶足跖肿胀试验观察其抗炎作用,热水缩尾试验观察其镇痛作用,小鼠凝血试验观察其对凝血时间的影响,大鼠动静脉旁路血栓试验观察其抗血栓作用,垂体后叶素致大鼠心肌缺血试验观察其心肌保护作用。结果:舒胸片和SECG均能降低角叉菜胶导致的小鼠足跖的肿胀度,降低小鼠足局部炎症组织中前列腺素-2(PGE2)含量,增加超氧化物歧化酶(SOD)活性;提高痛阈;延长凝血时间;抑制血栓生成;抑制心肌缺血,使心肌组织中肌酸激酶(CK),乳酸脱氢酶(LDH),脂质过氧化产物丙二醛(MDA)含量明显降低,SOD活性明显升高。并且舒胸片、SECG两种组方作用一致。结论:舒胸片和SECG在抗炎、镇痛、抗凝血、抗血栓和心肌保护方面的作用效果一致,且量效关系也一致,说明SECG是舒胸片的起效成分,SECG可以替代舒胸片应用于研究及临床。

Pharmacological study on the substitution of effective compounds group for Shuxiong Tablet

AIM:To compare the difference between Shuxiong Tablet(Radix et Rhizoma notoginseng,Flos Carthami,Rhizoma Chuanxiong)(SXT) and its effective compounds group(SECG) in anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.METHODS:We adopted experiments of carrageenan-induced paw edema,hot water shrink trail,clotting time in mice,and thrombus in arteriovenous shut,and pituitrin induced acute myocardial ischemia in rats.RESULTS:Both of SXT and SECG could inhibit the tumefaction,decrease PGE_2 and SOD in inflammatory tissue;enhance the pain threshhold of mice;extend clotting time;inhibit the thrombosis;inhibit myocardial ischemia,significantly decrease CK,LDH,MDA and increase SOD in myocardial tissue.CONCLUSION:SXT and SECG have the same effects on anti-inflammatory,relieving pain,anticoagulation,anti-thrombus and myocardial protection.Further more,their dose-response relationship curves were similar,suggesting that SECG having the main effective components of SXT,could take place of SXT in clinical research.
