The effect of norepinephrine (NE) was examined on the whole-cell Ba2+ current through L-type Ca2+ channels of freshly isolated smooth muscle cells of guineapig vas deferens. The magnitude of maximum Ba2+ current [IBa(max)] varied in different cells, although the capacitance of the cell membrane was
