80) Mobility of ions. Electrophoresis its kinds.

Phases of heterogeneous system will come in movement owing to interaction with an electric field if to system to put a constant potential difference. Movement of particles of a disperse phase in an electric field on a direction to opposite charged electrode is called electrophoresis. Electrophoresis has been opened F. Rejssom in 1807.

Electrophoresis is movement of the weighed particles (phials of gas, colloidal particles and macromolecules) in a liquid under action of an electric field. The method combining influence on an organism of a constant current and introduction of medicinal substances, is called medical electrophoresis or iontophoresis.

Electrophoresis has received wide application in clinical researches of blood, gastric juice, urine, spinal fluid in modern medicine. Electrophoresis is applied in physiotherapy. Usually two basic methods are applied - macroscopic and microscopic electrophoresis.

Macroscopicelectrophoresis is used for division of the substances which are being a mix, and their subsequent allocation.

Microscopic electrophoresis is used for determination of mobility of ions, cells, particles in an electric field, e electrokinetic potential, and also electrochemical properties of a surface of investigated substances.

81) Medicinal electrophoresis.

Medicinal electrophoresis - a combination of influence on an organism of a constant electric current and the medicinal substance entered with its help. Thus medical effects of entered medicinal substance are added to mechanisms of action of a direct current. They depend on mobility, a way of introduction, quantity of medicine acting in an organism and area of its introduction. Medicinal substances in a solution break up to ions and charged hydrophilic complexes.

82) Galvanizing.

The medical method, at which action on an organism of a direct current of insignificant force is used, is called galvanizing. It is connected with the old name of a direct current - a galvanic current. Primary action of a current on tissues of an organism is connected with movement in tissues of ions of electrolytes and other charged particles. Division of ions and accordingly, change of concentration of ions in various elements of tissue structures occurs owing to different mobility of ions, and as delays and their accumulation at semipermeable membranes, in tissue elements, outside and inside of cells.

Galvanizing is combined with a high-frequency magnetotherapy (inductothermy), and acupuncture.

Galvanizing is used at treatment

- traumas and diseases of peripheral nervous system;

- traumas of spinal, frustration of brain and spinal blood circulation;

- a vegetative dystonia, neurasthenias and other neurotic conditions;

- diseases of bodies of the digestion, proceeding with infringement motor and secretory functions ;

- hypertonic and hypotonic illness, a stenocardia, an atherosclerosis in initial stages;

- chronicarthritises and periarthritis a traumatic, rheumatic and exchange origin.
