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.

结果显示，该药物具有负性肌力和负性频率作用，降低左室压及其微分，终使每分心输出量减少；缩短豚鼠心室乳头肌动作电位时程的〓和APD〓，大剂量使动作电位平台消失，〓延长；同位素示踪法研究证实L-THP抑制〓摄取，促进〓释放，降低细胞内的〓含量；单通道水平的研究证实，L-THP减少豚鼠心室肌单细胞内向钙电流，且具有剂量，电压，频率依赖性，其作用易于洗脱，药物剂量与Ica也具有高度相关性（相关系数r为-0.87）；L-THP还可抑制ISO损伤心肌组织所致的丙二醛含量增加，增加谷胱甘肽过氧化物酶的量，使组织细胞免受损伤。L-THP阻断L-型〓通道，抑制〓的摄取，促进〓的释放，降低细胞内〓含量L-THP作用的离子基础。
