In the guinea-pig ileal longitudinal smooth muscle, Ba caused an initial phasic contraction, followed by a gradual decrease of the contraction (tonic contraction). In the Ca-free and the Ca-free, K-rich physiological solution, Ba could also contract the longitudinal muscle, but 30 min- and 60 min-immersion of the tissue in the Ca-free solution decreased lower than 20% of control of the Ba contraction. Although the K-induced depolarization intensified the Ba contraction after the 30 min…
