[Electrophysiologic and contractile properties of cells of the oblique layer of the musculature of the pyloric region of the stomach in white rats].
The double sucrose gap technique revealed increase of the amplitude of electrotonic potentials and decrease of their time constants of growth and fading as the result of polarization current enhancement. Latency of both potentials become shortened and their number and frequency increase. The initiation of contraction response coincides with the potential development, its amplitude and velocity being determined by the AP. The effects of acetylcholine and noradrenaline were investigated.
