    “…Data from analyses of serum and skeletal muscle showed (a) a fall in serum chloride concentration and an increase in serum carbon dioxide concentration and pH in the potassium-deficient rats; (b) increases of sodium, magnesium, and calcium and a decrease of potassium in the muscle of the potassium-deficient rats; (c) no change of muscle chloride or carbon dioxide concentrations in the potassium-deficient rats. (2) Application of the Wallace-Hastings calculations to these data revealed (a) intracellular pH of the skeletal muscle of the normal rat to be 6.98 ± 0.08; (b) an increase in serum partial pressure of carbon dioxide (pCO(2)) in potassium deficiency, together with increases in concentrations of [H(2)CO(2)] and [HCO(3) (-)] per kg. extracellular water and [H(2)CO(3)] per kg. cell water; (c) a decrease in values for [CO(2)] and [HCO(3) (-)] per kg. intracellular water; (d) a fall of intracellular pH in potassium deficiency to 6.42 ± 0.05. (3) Analyses of sacrospinalis muscle from five men undergoing operation for ruptured intervertebral disc showed a mean value of 9.46 ± 1.31 mM carbon dioxide per kg. blood-free tissue. …”
