Abstract
An increase in extracellular potassium concentration from 4 to 16 mmol/l caused a decrease in membrane potential from -92 to -59 mV and selectively diminished the earlier of two contraction components of guinea-pig papillary muscles at 0.2 Hz stimulation frequency in the presence of noradrenaline. The influence on the early contraction component had a threshold of 8 mmol/l K+, corresponding to a membrane potential of -77 mV. However, test contractions elicited 800 ms after the 5 s stimulation interval exhibited an unimpaired early component. Since the activator calcium responsible for the early contraction component is derived, in mammalian ventricular muscle, from the junctional sarcoplasmic reticulum, it is assumed that the release site of the reticulum was filled with calcium shortly (800 ms) after a regular contraction, and lost its calcium at 16 mmol/l extracellular K+, during the 5 s stimulation interval. The potassium-induced depolarization determined the rate of calcium leakage during rest from the intracellular store. The depolarization-induced decline of the early contraction component was equally well antagonized by Mg2+ or Ca2+ without influencing the measured transmembrane potential. Both divalent cations shifted the relation between potassium concentration or membrane potential and the strength of the early contraction component to less negative membrane potentials. In order to reduce the early contraction component by 25% in the presence of 9.6 instead of 1.2 mmol/l Mg2+, the potassium concentration had to be increased from 9.6 to 22.0 mmol/l, with a respective decrease in resting membrane potential from -72.6 to -51.1 mV. The antagonistic effect of both divalent cations is though to result from the neutralization of negative charges outside the sarcolemma with a respective decrease in the outside surface potential.

Abstract
Serum stimulates embryonic avian skeletal muscle growth in vitro and the growth-related processes of amino acid transport and protein synthesis. Serum also stimulates myotube Na pump activity (measured as ouabain-sensitive rubidium-86 uptake) for at least 2 h after serum addition. Serum-stimulated growth depends on this Na pump activity since ouabain added at the same time as serum totally inhibits the growth responses. The relationship of myotube growth, Na pump activity, and transmembrane potential was studied to determine whether serum-stimulated Na pump activation and growth are coupled by long-term membrane hyperpolarization. When myotube amino acid transport and protein synthesis are prestimulated by serum, ouabain was found to have little inhibitory effect, indicating that the already stimulated growth-related processes are not tightly coupled to continued Na pump activity. Serum-stimulated protein synthesis is tightly coupled to Na pump activity, but only during the first 5-10 min after serum addition. When myotube transmembrane potentials were measured using the lipophilic cation tetraphenylphosphonium, serum at concentrations that stimulate myotube growth and Na pump activity was found to have little effect on the cell's transmembrane potential. Furthermore, partial depolarization of the myotubes with 12- to 55-mM extracellular potassium does not prevent serum stimulation of myotube growth. Monensin was found to hyperpolarize the myotubes, but causes myotube atrophy. These results indicate that although Na pump activity is associated with initiation of serum-stimulated myotube growth, continued Na pump activity is not essential, and there is little relationship between myotube growth and the myotube's transmembrane potential.

Abstract
The pH difference across the cell membrane of frog sartorius muscle cells was measured with the distribution of 5,5-dimethyl-2,4-oxazolidine-dione (DMO) as the marker. Depolarization of the muscles to values at or below the contraction threshold caused by elevating external potassium up to approximately 20 mM resulted in an internal alkalinization. The change was smaller with superthreshold depolarization (20--30 mM [K+]). The alkalinization was blocked by agents that block calcium release from the sarcoplasmic reticulum (procaine and dantrolene sodium). Other agents that cause calcium release (caffeine, theophylline, and quinine) were found to give alkalinization when tested at concentrations just below the contracture threshold. Increased acidification of the extracellular medium was associated with the internal alkalinization. The data were interpreted as indicating the presence of a calcium-stimulated H+ and/or OH- ion transport system in the muscle membrane.

Abstract
Parallel measurements have been made of the oxygen consumption and efflux of radioactive sodium in pairs of frog sartorius muscles. Calculation of the amount of secretory work necessary for an active extrusion of sodium at the observed rate showed that it would involve the utilization of about one-tenth of the energy available from resting metabolism.This figure may reasonably be regarded as a lower limit to the efficiency of the secretory mechanism. Some of the measurements were made in a potassium-free Ringer’s solution, and others with an external potassium concentration of 10mM. In the potassium-rich medium, both the sodium efflux and the oxygen consumption were increased, the proportion of the energy production required for sodium extrusion remaining roughly constant. The action of dinitrophenol and other metabolic inhibitors on the sodium efflux in sartorius muscles was examined, but there were no very obvious effects.
