[Comparative evaluation of the anti-arrhythmic activity of carbamazepine, novocainamide and obzidan in ventricular extrasystole].

Twenty-six patients with different diseases of the myocardium complicated by ventricular extrasystole were studied by means of intermittent 24-hour ECG-monitoring using the "Malysh" apparatus. Control of treatment was performed on the 4th-6th day. Carbamazepine effect was observed in 2/3 of patients and significantly exceeded effects of obzidan and novocainamide.

[Sugar transport regulation in vitro by new calcium ionophores].

The influence of calcium ionophores--tenoyltrifluoroacetate (TTFA) and divaleryldibenzo-18-crown-6(divaleryl) on the glucose consumption, D-xylose transport and glycogen content in rat diaphragm was studied. TTFA caused a clear dose-dependent inhibition of carbohydrate transport and glycogenolysis stimulation. Divaleryl, on the other hand, raised glucose consumption, D-xylose transport without influencing glycogen content.
