摘 要:目的:对三七生药生物转化后所提总皂苷进行药理研究,初步判断转化效果。方法:采用断头脑缺血、体内血栓形成、氯仿致心律失常及离体心脏灌流实验。结果:腹腔注射1号-5号样品100、200mg/kg,对断头脑缺血小鼠均有明显保护作用;1号200mg.kg-1.d-1×5d,能明显抑制胶原-肾上腺素诱导小鼠体内血栓形成;除1号100mg/kg外,各组均能明显对抗氯仿诱发小鼠心律失常,3、4号高剂量与5号高剂量组相比室颤发生率有所降低;与生理盐水对照组相比,1-4号保留了扩张冠脉,但对心肌收缩力和心脏前负荷的影响各有差异。结论:转化后样品与对照品在药理作用上发生了一定变化,提示转化后的三七总皂苷化学结构可能有所变化,与初步的化学分析结果相吻合。Objective: To compare the pharmacodynamic action of Radix Notoginseng after fermented by different strains bioconversion. Methods: The models of cerebral ischemia and hypoxia were established , thrombosis in vivo were induced by collagen-Adr, ventricular fibrillation of mice by chloroform, and perfusion experiment of the ex vivo heart of cavia cobaya was used. Results: 100, 200mg/kg doses of all samples had protective effects on ischemia and hypoxia mice, 1 # sample can inhibit thrombosis induced by collagen-adrenaline obviously after intraperitoneal injection in dosage of 200mg· kg^- 1 ·d^- 1 for 5days. All groups significantly reduced the incidents of ventricullar fibrillation induced by chloroform in mice except 100mg/kg dose of 1 # , furthermore, compared with control high dose group (5 # ), the incidents of high dose groups of 3,4 # deceased significantly. All samples had the effect of dilating coronary artery,but there effects on myocardial contractile force and cardiac preload were different. Conclusion:The primary cardiovascular related pharmacological researches demonstrated the vary action changes of 1 - 4 # samples compared with the sample 5 # . This result has revealed that the chemical structure of Radix Notoginseng transformed and that is coincide with initial analysis of phytochemical analysis.
