It was found that ouabain and marinobufagenin, specific inhibitors of Na+,K+-ATPase, increased the contraction of the isolated rat diaphragm by ∼15% (positive inotropic effect) at EC50 = 1.2 ± 0.3 nM and 0.3 ± 0.1 nM, respectively, which was indi

Effects of Na+,K(+)-ATPase inhibitor: marinobufagenin, on contractile and electric characteristics of isolated rat diaphragm were studied for the first time. Marinobufagenin induced dose-dependent (EC50 = 0.3 +/- 0.1 nM) increase in the contraction f

Acetylcholine (ACh) hyperpolarized the rat diaphragm muscle fibers by 4.5 +/- 0.8 mV (K0.5 = = 36 +/- 6 nmol/l). The AC-induced hyperpolarization was blocked by d-tubocurarine and ouabain in nanomolar concentrations. This effect of ACh was not observ
