The site refers EurekAlert Said that high blood pressure is the leading cause of cardiovascular disease and death due to stroke and myocardial infarction in the world, where about 40% of the population of the Earth and 25 years and older suffer from hypertension.
Eating salt on the table helps to increase blood pressure: the more salt people consume, the more sodium ions accumulate in the blood plasma and cerebrospinal fluid. This in turn stimulates the sympathetic nervous system that regulates the blood circulation.
The special sodium channels, the structure of the cell membrane proteins through which sodium ions enter the cell, consist of glial cells, including astrocytes and neural cells, which provide communication between the nervous system and the cells. blood vessels. Scientists have shown that sodium channels are a sensor and monitor the high concentration of sodium ions in the blood and cerebrospinal fluid.
In mice whose limbs do not have sodium channels, the sympathetic nerve is not activated by heavy salt consumption. In wild mice, their glial cells receive biochemical reactions. The extracellular sodium ion stimulates the opening of sodium channels, which causes lactate formation (LDH), Which activates the cells of the thalamus and spinal cord as it exits with hydrogen ion cells, which stimulates the sympathetic nerve.
