M-cholinoreactivity dynamics in frog myocardium exposed to serum from human umbilical blood
In experiments with isolated hearts from 31 frogs (R. ridibunda), acetylcholine (10-7, 10-6, 10-5g/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 negativ...
