Abstract
Taurine exerted a protective effect against the decline in the Ca2+- dependent slow action potentials (APs) caused by hypoxia (Sawamura et al., 1986a), but did not induce Ca2+-dependent slow APs (Sawamura et al., 1986b) and did not elevate cAMP level (Sawamura et al., 1983). Taurine also exerted a positive inotropic effect (in perfused embryonic (20-day-old) chick heart) without affecting the slow APs, and it was suggested that the positive inotropic effect was not mediated through an increase in slow Ca2+ current (Sawamura et al., 1986b). The effects of taurine on the Ca2+ slow current in guinea pig myocytes depended on the external Ca2+ concentration (Sawamura et al., 1990).
