[Metabolic alkalosis. Relation between bicarbonate load and the behavior of blood lactic acid in the light of the intra-erythrocyte indices of the acid-base balance].
The plasma an intra-erythrocyte acid-base balance in man was studied, along with blood pyruvate and lactate levels, in acute metabolic alkalosis induced by i.v. infusion of bicarbonate. It was found that the red cell offers a satisfactory expression of the phenomena that occur in the intracellular space. The bicarbonate ion has difficulty in crossing the red cell membrane, while the production of lactate is seen as a fundamental compensation mechanism for rapid buffering of the extra base.
