Аннотация

In experiments on the isolated rat heart there were studied the effects of different doses (21.43 mg/kg/day and 85.72 mg/kg/day) 2-ethyl-6-methyl-3 hydroxypyridine succinate ("EkoPharmInvest", Russia), on the contractile function of isolated hearts subjected to prior doxorubicin model (20 mg/kg, intraperitoneal) of pathology. The dynamic of the power mechanisms of ion transport was evaluated by imposing high heart rate (480 BPM) and increase concentration of Са2+ to 5 mmol in perfusate. The results indicate that Mexicor at the dose of 21.43 mg/kg/day does not provide a cardioprotective effect in this model of pathology. Mexicor has the cardioprotective effect at the dose of 85.72 mg/kg/day in relation to the isolated heart, that is resulted in the recovery of the contractile function of the heart and reducing the "diastole defect" (SТТI).
