1. This study was designed to investigate the mechanism(s) of the negative inotropic effects of alpha1-adrenoceptor agonists observed in rat isolated left atria after exposure to free radicals. 2. Ouabain and calphostin C were used in contraction experiments to block the sodium pump and protein kinase C. Methoxamine-induced phospholipase C and Na+/K+ ATPase activities were measured. 3. Methoxamine (300 microM) increased contractile force by 1.6 +/- 0.2 mN in control atria but decreased contractile force in electrolysis-treated atria by 2.0 +/- 0.1 mN (P |
