title: [Different effect of the ''recombinant'' bradykinin on the contractile activity of cultured atrial and ventricular cardiomyocytes].
abstract: The physiological activity of the "recombinant" bradykinin expressed by retrovirus recombinant pPS-3-neo (brd) was tested on cultural atrial (aCMC) and ventricular (vCMC) cardiomyocytes in newborn rats. The "recombinant" bradykinin was shown to have a chronotropic effect on aCMC and an inotropic effect on vCMC. The effects are in line with the action of the synthetic bradykinin preparation at a concentration of around 10(-15) M. A pretreatment of CMC by parmidine, i.e. a bradykinin antagonist, blocked the effect of bradykinin. The contractive CMC activity in the cultural cell medium, transferred by pPS-3-neo without the bradykinin gene, was not different from the control value.
