  1. The cerebral arteries were from groups of fresh air and SHS for 2 and 4 weeks. K+-induced responses were expressed as absolute values of contraction (mN). S6c and ET-1-induced responses were expressed as percentage of K+-induced contraction. Emax, maximal contraction; SHS, secondhand smoke exposure.
