ИЗМЕНЕНИЕ М-ХОЛИНОРЕАКТИВНОСТИ МИОКАРДА ЛЯГУШКИ ПОД ВЛИЯНИЕМ СЫВОРОТКИ ПУПОВИННОЙ КРОВИ ЧЕЛОВЕКА

In experiments with isolated hearts from 31 frogs (R. ridibunda), acetylcholine (10 -7 , 10 -6 , 10 -5 g/ml) in a dose-dependent manner reduced contraction amplitude during electrostimulation (30 s, 1 Gz, 5 ms, 5-10 W). The time to achieve maximal amplitude did not change, that meant the serum had n... View More
