Results showed that L-THP possessed negative inotropic and negative chronotropic action, lowed left ventricular pressure and it's infinitesimal calculus, decreased heart output in per min., shorten 〓 and 〓 of action potential of ventricular papillary muscle of guinea pig and even the plate-phase of action potential disappeared in larger dose group , but prolonged 〓. we studied transmembrane transportation of 〓 after administering L-THP , L-THP not only depressed uptake and increased release of Ca 2+ in normal myocardium, but also it showed stronger inhibition in cell injured by ISO, and fully eliminated the effect of ISO increasing uptake and decreasing release of 〓. By detecting the 〓 content of ventricular single myocyte using fluorescent probe Fluo-3/AM, results correspond to that done above, L-THP decreased 〓 content inside of cell significantly. Using whole-cell mode, we observed the effect of L-THP on Ica in ventricular single cell, it was found that L-THP decreased Ica, the effect increased with increasing it's dose, and had voltage, frequency-dependency. Dose highly corelated to effect, corelative constant is 0.87. When washing cell with normal tyre's solution, Ica could recover, which proved the blocked action of L-THP on calcium channel once again. Meanwhile, L-THP reduced production of MDA in heart injured by ISO in dose-dependent manner, improved content of GSH-Px, in case tissue or cell free from free radical damage.
