| Popis: | By applying of aconitic test in in vivo experiments in rats under deep anesthesia, there was investigated the antiarrhythmic potential of newly synthetized fluorinated derivatives of propafenone. The animals were divided into four experimental groups. The first (aconitine group) was treated with aconitine at a dose of 60μg/kg, which led to pronounced cardiac rhythm disorder in a short period of time. The appearance of ventricular extrasystole (VES) was taken as a parameter for ascertainment of cardiac rhytm disorder. The remaining three animal groups were taken for testing the potential of propafenone and propafenone fluorinated derivatives to stop the arrhythmia, and which was induced by i.v. aconitine injection (60|jg/kg). Propafenone, as well as 5OF derivative, did not convert the disturbed cardiac rhythm (survival of animals was 0%). By applying 5PF derivative in a dose of 6 mg/kg, the animals survived with occasional establishment of sinus rhythm. [Projekat Ministarstva nauke Republike Srbije, br. TR 31020 i br. OI 172041] |
