title: [Effect of noradrenaline on the amplitude and temporal parameters of multiquantal currents and on the kinetics of evoked quantal secretion of a transmitter].
abstract: Noradrenaline caused a significant increase of the multiquantal endplate currents (EPC) amplitude, the EPC rising phase/the rising phase of miniature EPC ratio diminishing, at that. Noradrenaline seems to synchronise the process of quanta secretion in the EPC generation. Thus when a single stimulation of motor nerve results in release of several tenths of a transmitter, noradrenaline may increase the multiquantal EPC amplitude through synchronising of the transmitter release involved in the generation.
