Sodium And Potassium

We have shown that the sodium concentration in whole blood measured by direct potentiometry is higher than in plasma. The ‘erythrocyte-effect’, already described by Siggaard Andersen, is most pronounced for instruments equipped with a reference electrode with an open static liquid junction and is thus a general phenomenon. Instruments with a modified liquid junction show less interference. The same phenomenon appears for the determination of the potassium concentration, although the difference between whole blood and plasma, when measured with instruments equipped with a modified liquid junction, can be neglected in practice.

Abstract Several methods are available for determination of glucose in whole blood and serum. When comparing the results of these methods on a single blood sample, one may find significantly different values. Here, equations are provided for converting values for whole blood glucose to values for serum glucose, obtained by different methods.

1. The presence of a large intracellular pool of free amino acids in the haemocytes of Carcinus maenas (L.) is described. It was found that 58 % of the total free amino acid concentration of a whole-blood sample was present in the cell fraction. 2. The blood-cell count for Carcinus was found to be around 33,000 cells/µl which corresponded to 1 % by volume of the whole-blood sample. Thus 58 % of the total free amino acid concentration of the blood sample is sequestered into 1 % of the total volume. 3. The pattern of the amino acid pool of the haemocytes is shown to differ from that of muscle and nervous tissue from Carcinus. In particular, the taurine molecule accounted for 50 % of the pool in the haemocytes. 4. Possible functions for the amino acids of the haemocyte pool are suggested and the results are discussed in relation to other studies on free amino acids in crustacean blood.
