The effects of 2,3-butanedione monoxime (BDM) were studied in smooth muscle fibres from guinea pig taenia colt. In intact muscle, active force during contractions induced by high-K + was inhibited by about 10% in I mM BDM and by approximately 70% in 10 mM BDM. Intracellular [Ca 2+ ] during contracti
