CELL PULSATION AND PERFORMANCE OF CARDIOVASCULAR SYSTEM

Cell pulsation is the life itself. It plays the leading role in provision of cell by oxygen, nutritive matter, in elimination of metabolism products, in maintenance of homeostasis and in cell division. Pulsation mechanism is spontaneous interturn hydration of cytoskeletal protein and change of hydration to dehydration, when the heat of ATP hydrolysis raises the temperature up to 44 ºC. The necessity of continuous ATP requires continuous oxygen supply in cell. At the same time, cell shrinkage at cytoskeleton dehydration is the mechanism of thermal energy transfer into mechanical one. Hydration and dehydration are important for muscle work and neurotransmission. The pulsation character is determined by the content of cytoplasm, the character of tissues (the content of tissue fluid) and also the environment. Technogenic pollution of the environment affects cell pulsation, which is associated with various pathologies.
