The effects of total saponins of Panax notoginseng (PNS) on contraction force, normal and slow response action potentials and slow inward current of guinea pig papillary muscles were studied by intracellular microelectrodes and voltage clamp techniques. The contraction force was decreased and the APD20, APD90 of normal AP were shortened in the presence of… CONTINUE READING
