The effect of some membrane active ionophoric antibiotics on the amplitide of contractions of isolated rat heart right ventricle was studied. The effects of polyether nigericin polyene amphotericin B and peptide antibiotic polymyxin B were examined. Nigericin in a concentration of 1.38 micromol/L exerts a positive inotrophic effect with its maximal value (+28%) 15 minutes after application. Amphotericin B in a concentration of 1.08 micromol/L caused a positive inotropic effect, which was maximal in the 30th minute of the experiment (+28%). Polymyxin B in a concentration of 0.84 micromol/L caused a positive inotropic effect, which was maximal (+32%) 20 minutes after application.
