9-Phenanthrol hyperpolarizes vascular smooth muscle cells in pressurized cerebral arteries. A: representative recordings of smooth muscle cell membrane potential in cerebral arteries pressurized to 70 mmHg under control conditions, following administration of 9-phenanthrol (30 μM), and after the compound was washed out of the superfusion bath. B: summary data showing the effects of 9-phenanthrol on smooth muscle cell membrane potential; n = 4 for control and 9-phenanthrol; n = 3 for Wash. *P ≤ 0.05 vs. all other groups.
