title: [Antiarrhythmic effects of kappa-seleno-carrageenan in experimental animals].
abstract: The effect of Kappa-seleno-carrageenan, an organic compound containing selenium, on aconitine, BaCl2 and ouabain-induced arrhythmias were studied. When rats were given ip 9 mg.kg-1.d-1 x 5 d or ig single dose of 35, 70, 140 mg.kg-1, the threshold dose of aconitine was elevated significantly to induce HA. The effect seems to resemble that of ip Na2SeO3 1 mg.kg-1 x d-1 x 5 d. With increasing ig dose, the threshold dose of aconitine was elevated for inducing VE, VT, VF. When ip 9 mg.kg-1 x d-1 x 5 d or ig 70 mg.kg-1 was given, the threshold doses of BaCl2 in inducing VF (in rats) and ouabain in inducing VE (in guinea-pig) were elevated. However, no influence was observed for ip Na2SeO3 1 mg.kg-1 x d-1 x 5 d.
