Contractile responses induced by S6c (A) and ET-1 (B) in rat cerebral arteries. The cerebral arteries were isolated from groups of fresh air, SHS and SHS treatment with GW5074. Contractions were induced by cumulative application of S6c or ET-1 (n = 8-10). *P < 0.05, **P < 0.01 versus fresh air group, #P < 0.05 versus SHS group; SHS, secondhand smoke exposure; GW, GW5074 (0.5 mg/kg).
