title: Stabilizing effect of Silene pectin polysaccharide on electrical activity of the sinoatrial area in frog heart.
abstract: Silenan, a pectin polysaccharide from common catchfly (Silene vulgaris), corrects disorders in the conduction of action potentials between cells of the sinoatrial area of frog heart forming a functional syncytium. Recovery of action potential conduction in the sinoatrial cells was recorded in long-term experiments (>8 h). The effect of silenan manifested mainly against the background of arrhythmic generation and impaired propagation of action potentials.
