Gene expression in fibroblasts and fibrosis: involvement in cardiac hypertrophy.

abstract：:The inward current ("oscillatory current") which may be present after the end of a depolarizing clamp was studied in sheep cardiac Purkinje fibers by means of a voltage-clamp method. The following results were obtained. In order to appear, the oscillatory current (Ios) requires a previous depolarization to approximate...
