Abstract: Objective: To study the effect of tolerance hypoxia of hypoxic cardiomyocyte mice by combined application of compound solvia miltiorrhiza injection and betaine hydrochloride, to compare the effect of the two drugs with that used alone, and to establish a laboratory foundation in developing new drugs. Methods: Mice models of myocardium anoxia increase were induced by injected isoprenaline. Then put mice into the obturated vases and record the accumulative oxygen consumption of different time and the survival time of mice. Rusults:Compared with that in mice received compound solvia miltiorrhiza injection or betaine hydrochloride alone, the accumulative oxygen consumption of 5 and 10 minutes were reduced obviously and the survivial time were prolonged in mice received compound solvia miltiorrhiza injection and betaine hydrochloride. There were no significant difference between compound solvia miltiorrhiza injection group and betaine hydrochloride group. Conclusion:Compound application of compound solvia miltiorrhiza injection and betaine hydrochloride has a notable result in anti?hypoxic cardiomyocyte, moreover the effects are better than the single drug.
