N2 - The free intracellular Ca2+ concentration changes in cardiac myocytes were compared after visible light irradiation and upon exposure to low concentration H2O2. Illuminating low energy doses (6 J/cm2) of visible light, or adding low concentration of H2O2 (35 μM) to cardiac cells resulted in elevated oscillations of [Ca2+]i that lasted for 200 min. Contraction of heart cells was also observed in parallel to calcium elevation. H2O2 mimicked the influence of light on [Ca2+]i, as well as on the biostimulatory effects.
