Beta-adrenergic stimulation of 42K influx in isolated smooth muscle cells.

The present studies were designed to examine the effect of the beta-adrenergic agent isoproterenol (ISO) on 42K influx into isolated smooth muscle cells. Unidirectional 42K influx studies were carried out as described previously using suspensions of smooth muscle cells derived from the toad stomach. Results from these studies indicated that ISO (10(-4) M… CONTINUE READING
