Angular distribution for scatterings of 3He、4He、6He and 7He with hydrogen bromide molecules are calculated by using close-coupling approach from the anisotropic intermolecular potential of the He-HBr system established by the author. The calculations are performed separately at the collision energies of 60 and 100 meV. The influences of He isotope atoms on angular distribution is discussed in detail.

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.
