[The water-electrolyte-change and the age (author's transl)].
In 403 healthy probands between 20 and 103 years old the ionogram of the erythrocytes and of the plasma was analysed. In the one part of the test persons (75 probands) also the water spaces of the organism was examinated. It was established, that the electrolyte composing of the blood is changing with increasing age. In the erythrocytes the content of potassium, magnesium decreases, the content of sodium and chloride increases; in the blood plasma the content of potassium, calcium, magnesium and acid carbonates decreases, the content of acid radical groups--sulphates, phosphates, chlorides and organic acid increases. In an examination of the water spaces was an age depended decreasing of the quantity of total and of the intracellular fluid remarked. The changes probably show the state of the metabolic processes in the age, which is characterized by decreasing of the total metabolism and decreasing of insufficient oxydised products.
