[Analysis of changes in the membrane potential of denervated muscle].
Quantitative analysis of the experimental data presented in the previous paper has shown that the electrogenic pump component of the membrane potential of muscle fibres on the third day after denervation is in the average 8.7 mV, and the diffusion component--12.9 mV lower than that in the normal fibres. It is due to a decrease of the stechiometric coefficient of Na+,K+-pump at denervation from 2.15 to 1.3 and to a change of the passive ionic permeability: at denervation permeability for Na+ increases from 0.52.10(-7) to 0.67.10(-7) cm.sec-1, and for K+ decreases from 0.75.10(-5) to 0.53.10(-5) cm.sec-1.
