The impact of magnetic techniques negatively and positively on the cells and tissues of the body (between fact and fiction)

Recent decades have witnessed rapid progress in the various electrical engineering tracks, especially in the field of communications and computers, so that the general environment has become a sea of ??electric and magnetic signals and frequencies, and these signals are frequencies emanating from television, radio, mobile and fixed communication devices. The researchers proved that the decrease in the intensity of the Earth's MF magnetic field caused by environmental electronic pollution is related to the negative effects arising from the internal electronic environment that breaks down the cellular structure inside the body. Also, some studies have proven that the level of magnetic fields MFs resulting from some devices is somewhat high to a degree that may affect public health. The number of those exposed to these fields increased with the increase in technological development. The percentage of those exposed in 1991 was 15%, and it has increased to about 40% at the present time.

In recent years, many studies have shown the possibility of determining the effects on the biological systems of animals and humans as a result of continuous exposure to those magnetic fields. The biological response to exposure to these fixed fields and from all negative and positive directions was discussed, despite the failure of some epidemiological studies in the existence of a relationship between continuous exposure to these fields and components.

Every cell of the body contains negative and positive magnetic charges, so these cells are in a state of neutrality when these charges are equal and when any imbalance in those charges may lead to harmful effects on the cellular balance, and general limits have been set for the amount of magnetic intensity that must be exposed daily. It is allowed to maintain that balance, and there is a belief that the magnetic charge fades when the cells perform their function inside the body, and thus the body converts those cells that lose the magnetic charge by sending pulses of electromagnetic energy to the brain and this energy is called biomagnetic.

Biomagnet works on the flow of ions across the cell membrane through the tendency of ion concentration between inside cells (cytoplasm) and outside cells (environment). Also, the chemical reactions that occur inside the cells of the body of the organism make it produce a magnetic field and through ionic waves transmitted within those fields to the nervous system, and the exposure of those chemical and physical reactions that occur inside the cells to dangerous levels of magnetic fields may lead to a state of deterioration in the cellular balance .

The magnetic force works to regenerate the nervous tissue, as it stimulates the regeneration of the spinal cord through its effect on the flow of calcium ions through the membrane of the nerve cell, which in turn affects cellular functions. These magnetic fields were also used to relieve pain from the neck to the knee by helping it in the process of vascular perfusion. Some studies have proven the role of magnetic fields (MFs) in treating tissue infections. Research conducted on humans has shown that magnetic fields and technology have a clear effect on blood flow in the tissues of the extremities and were used in the treatment and healing of bones and in the process of fusion of fractures

The magnetic technology and its fields have a clear effect on the permeability of cell membranes, as these fields increase the production of ATP energy, and thus lead to an increase in the supply of oxygen and nutrients through the vascular system. It also works to balance the distribution of ions across cell membranes. Many studies have been conducted in the world at the cellular level to know the mechanism of interaction between magnetic fields and cellular activities, where studies were conducted outside the body of the organism by exposing natural cells or tissues raised from the body of the organism or different carcinogenic cells due to their ability to divide or grow rapidly, and that Such studies are important to determine the factors that play an important role in the occurrence of the cellular effect when humans or animals are exposed to magnetic fields for long periods of time

Exposing the bull’s sperm to a magnetic field of intensity 1.7 Tesla and in a direction perpendicular to the magnetic field led to an increase in the number of sperm and also indicated an increase in red blood cells and platelets. New cells, that is, the division of these cells and their addition around the collagen fibers added to the medium and in a direction perpendicular to the magnetic field. Exposure to static magnetic fields has recently proven that it plays a clear role in causing many changes in various biological systems, especially changes that occur in the ion channels of cell membranes.

One study confirmed that exposing cultured GH3 cells to a magnetic field of 0.5/Tesla intensity for three weeks leads to an increase in the diameter of these cells. Exposing cells to constant magnetic fields affects the early stages of human blood vessel lining development. In addition, the magnetically treated water works to charge the cells correctly, thus performing the cellular function correctly, such as the metabolism of nutrients and not allowing chemical poisoning. The plasma membrane is the component that separates the cellular components on the one hand and the external environment on the other side, as well as regulating Carrier proteins such as Na-k-ATP ases, exposing human neurons to a fixed magnetic field (SMF) of (0.1, 0.5, 5, and 7.5) milli Tesla affects the resting potential of these cells within five seconds of exposure. The use of an intensity higher than (7.5 mT) did not notice any effect on the potentiometric efficiency of those cultured cells. There are many studies conducted on different cells of different organs in the mammary glands to know the effect of fixed magnetic fields SMFs on the rate of cell division, proliferation and death. her death. As confirmed by many studies

Magnetic fields have a clear effect on the production of free radicals as superoxide ions in various cells and tissues. In a study conducted in 2002 on the effect of constant magnetic fields on increasing the flow of calcium ions strongly to the cells of the microvilli, which in turn allows the entry of these ions into the cytoplasm, and that the interaction of weak magnetic fields is of great importance for the survival of cells.
