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.

The study of the biological role of chemical elements in farm animals is one of the issues that scientists continue to investigate. A comprehensive study of the gene pool and phenofund of breeds and species of farm animals is being carried out in Siberia. An important issue is the search for vital markers of macronutrient accumulation, including sodium in organs and tissues of animals. The article presents data on the content of sodium in the blood serum of offspring obtained from bulls-producers of the Holstein breed. The experiment was carried out at OAO Vaganovo, Kemerovo region. The sodium concentration was determined by the atomic emission method on an ICP AES IRIS spectrometer at the V. S. Sobolev Analytical Center for Collective Use of the Institute of Geology and Mineralogy SB RAS. In the area of Holstein cattle breeding, there is no excess of LOC for heavy metals in soil, water, feed, organs and tissues of animals. The influence of the genotype of the fathers of the Holstein breed on the sodium content in the blood serum of sons was established. The sodium concentration in Fabio’s offspring was 1.9 times higher (240.4 mg/ l) than in Brio’s sons (P ˂ 0.001). By the level of sodium in the serum of offspring, bulls-producers were arranged in the following order: Brio ˂ Bonaire ˂ Malstrom ˂ Fabio in a proportion of 1: 1.3: 1.5: 1.9. The phenotypic variability of this element between the offspring of different producers differed by 3 times or more. Interbreed differentiation, the influence of the genotype of producers, differences between lines and families sign the hereditary determination of resistance and susceptibility to the accumulation of macro- and microelements in organs and tissues of animals.
