[Effect of fenigidin on calcium metabolism in the frog heart].
The effect of fenigidine on calcium efflux from the frog heart was studied. In Ringer solution containing 10(-7) and 10(-5) M fenigidine, the efflux of Ca2+ was 0.081 and 0.23 mM per kg wet tissue, respectively. In a low-sodium solution (30 mM NaCl replaced by sucrose) containing fenigidine in the above-indicated concentrations, the efflux of Ca2+ dropped to 0.062 and 0.14 mM per kg wet tissue, respectively.
