Аннотация

The article discusses the physiological significance of the Na+/K+ ratio in blood serum as a criterion of a person’s functional state. Normally, in an adult, the ratio is 32.2 ± 0.5, it increases in a healthy person under the influence of extreme factors (space flight (cosmonauts, astronauts), long-term strict bedrest, etc.), with Covid-19 disease, and some orphan diseases in children. The issue of Na+/K+ in blood serum is being discussed, but not between the K+-rich cell and the Na+-dominated extracellular environment. The Na+/K+ ratio in blood serum is considered as an important parameter of a person’s physiological state and, depending on the numerical value, as an indicator of the functional state from normal to overload, severe complications to the prognosis of death.

2. Fig. 1. Dynamics of the Na+/K+ ratio in subjects in an experiment with prolonged bed rest (6 months). The abscissa axis shows the duration of the experiment in days. The ordinate axis shows the Na+/K+ ratio in the blood serum. The square is the initial value (light circles), the black line is bed rest, the transition to a normal motor regime is a double line. Arrow 1 is the beginning, arrow 2 is the end of bed rest [14].

3. Fig. 2. The Na+/K+ ratio in the blood serum of cosmonauts who completed a flight lasting from 18 to 241 days. Vertical axis – Na+/K+ ratio in the blood serum. Horizontal axis – flight duration. Legend: before the flight – black, after the flight – shading. The number of examined cosmonauts is in brackets: 18–30 (n = 8); 63–96 (n = 4); 140–175 (n = 18); 211–214 (n = 6). Reliability of differences after the flight to the data before the flight, * – p < 0.05, NS – not reliable [14].

4. Fig. 3. Na+/K+ ratio in the blood serum of American astronauts (n = 196) [15]. Vertical axis – Na+/K+ ratio in the blood serum. Horizontal axis – before and after the flight. Legend: before the flight – black, after the flight – shading. Reliability of differences after the flight to the data before the flight, ***– p < 0.001.
