[Effects of anti-cholinoceptor antibodies on the frog heart].


Research on isolated hearts of Rana temporaria has shown that upon treating them with anti-cholinoreceptor antibodies, there occurs a considerable reduction of inhibition effect on cardiac activity of acetylcholine or carbacholine. A reduction of inhibition effect was noticed after incubation of frog's heart with antibodies against cholinoreceptors obtained… (More)
