Luminescent polyelectrolytes with antiviral activity.

Radical polymerization was used to synthesize and characterize (co)polymers with sodium styrenesulfonate (NaSS), 4-methacryloylamidosalicylic acid (MASA), and -vinylpyrrolidone, which have a low cytotoxicity and a high antiviral activity against the human respiratory syncytial virus. The interaction of copolymers with Tb ions was studied. The complexes formed in dilute aqueous solutions at a concentration of MASA units ⩽ 1 · 10 mol L demonstrate a strong luminescence.

[Electrophysiological mechanisms of the effect of allapinin in patients with paroxysmal supraventricular tachycardia].

An intracardiac electrophysiological study was undertaken to examine 15 patients with paroxysmal supraventricular tachycardias. Allapinin intravenously given in a dose of 0.4 mg/kg, was tested for effects.
