Abstract
The main serum ions were determined in healthy, full-termborn infants having different plasma volumes. The serum sodium, potassium, and calcium concentrations were found to be constant, thus their circulating quantities were dependent on the actual plasma expansion. The serum inorganic phosphorus and magnesium concentrations were found to be inverselyrelated to the plasma volume and therefore the circulating total quantities of these ions remained constant in different expansion of the plasma volume. Biologisch wichtigste Ionen wurden im Serum von 24 ausgetragenen, gesunden Neugeborenen unter verschiedenen Plasmavolumina bestimmt. Die Natrium-, Kalium- und Calcium-Konzentrationen zeigen sich konstant, deshalb sind ihre zirkulierende Menge von der aktuellen Plasma-expansion abhängig. Die Konzentration des anorganischen Phosphors und des Magnesiums im Serum steht im umgekehrten Zusammenhang mit dem Plasma-volumen, demzufolge bleibt konstant die Gesamtmenge dieser Ionen im Kreislauf.This publication has 5 references indexed in Scilit:
