    Effects of sigma receptor ligand BD737 in rat isolated hearts

  • Original language description

    The present study was focused on possible effects of highly selective, high affinity sigma receptor ligand BD737 in rat isolated hearts perfused according to Langendorff. Electrogram recorded by touch-less method and left ventricular pressure acquired byballoon method were followed during acute exposure of isolated rat heart to nanomolar concentrations of the drug. Ventricular ectopic beats and periods of bigeminy were present in all experiments. Moreover, heart rate fluctuations were observed. In analogy to the positive inotropic effect previously described in isolated rat cardiomyocytes, BD737 exerted a slight insignificant increase of systolic pressure in our experimental model. In conclusion, the inotropic and chronotropic effects of sigma ligandBD737 in nanomolar concentration were confirmed in isolated rat hearts.

    Účinky ligandu sigma receptorů BD737 na isolovaná srdce potkana

  • Czech description

    Studie byla zaměřena na účinky vysoce selektivního, s vysokou afinitiou se vázajícího ligandu sigma receptorů BD737 na izolované srdce potkana perfundované dle Langendorffa. Byly zaznamenávány elektrogramy bezdotykovou metodou a tlak v levé komoře balonkovou metodou, a to v průběhu akutní expozice izolovaného srdce nanomolárním koncentracím této látky. Ve všech experimentech jsme zaznamenali komorové extrasystoly a periody bigeminie. Kromě toho jsme pozorovali fluktuace srdeční frekvence. Stejně jako uizolovaných kardiomyocytů potkana, kde byl dříve popsán pozitivně inotropní účinek BD737, i u izolovaných srdcí potkana tato látka působila nárůst systolického tlaku, ovšem nesignifikantní. Lze shrnout, že inotropní a chronotropní účinky ligandu sigma receptorů BD737 v nanomolárních koncentracích byly potvrzeny i u izolovaných srdcí potkana.
