[Effect of inhibitors of the active transport of ions on the spontaneous and evoked electrical activity of parenchymal mammary gland receptors].
In the potassium-free saline spontaneous activity of the mammary gland parenchyma receptor increased within first 30--40 min., then decreased and, finally, ceased. Sensitivity of the receptor to the mechanical stimuli decreased gradually. After washing in normal saline the evoked and spontaneous activities recovered. Ouabain (5 . 10(-5)--10(-4) g/ml) exerted an effect similar to that of the potassium--free solution except that the impulse activity could not be restored by the washing in physiological saline.
