Investigators at Harbin Medical University, Department of Pharmacology Have Published New Data on Cardiology.(Report)

New investigation results, 'Antiarrhythmic effects and ionic mechanisms of oxymatrine from Sophora flavescens,' are detailed in a study published in Phytotherapy Research. "Accumulating evidence indicates that oxymatrine may exert protective effects on the cardiovascular system. This study was designed to evaluate the antiarrhythmic effects as well as the electrophysiological properties of oxymatrine," scientists in Daqing, People's Republic of China report (see also Cardiology).

"The antiarrhythmic activity of oxymatrine was observed in a rat model of arrhythmia induced by coronary ligation. Action potential duration (APD), L-type calcium current (I(Ca-L) ), transient outward …
