About a rheology

4

Rheology (from Greek. Ρέος, "within the flow" and -logy) studies peculiarities of non-Newtonian fluid. Blood is a suspension hanging from its formed elements (platelets, red blood cells, white blood cells). The subject of study is the set of characteristics of blood flow, blood flow velocity, and hardness / elasticity of blood vessels.


The rheological laboratory research is assessing the status of hemorheological blood in various diseases (hypertension, diabetes, neuralgia, ischemic heart disease, stenos, defects, varicose veins, Reynaud's phenomenon, reconstructive surgery, pre- and postoperative periods, and many others). Also during pregnancy and childbirth blood rheology changes form.


For therapeutic purposes, the normalization of rheological parameters is very important. Rheological blood tests make it possible to select an optimal treatment strategy. It is the most informative method of modern medicine, which helps rapid healing of the patient and makes it almost impossible for the diagnostic doctor to mistake.

Enumeration Rheological Analyzes:

1. RBC agregability – "Georgian method";
2. RBC deformability – "Filtration method";
3. Plasma viscosity – "Capillary method";
4. Blood "apparent" viscosity – "Viscosity";
5. Platelet aggregability;
6. Platelet adhesion;
7. Resistance arteries vasodilatation;
8. The index of microcirculation;
9. Placental rheological analysis;
10. The distribution of RBC;
etc.

On the basis of rheological blood tests the doctor will recommend rheology and prescribe treatment in case of rheological disorders.

Centers of researches on rheology:
National Institute of Physiology (Okazaki, Japan); Central Physiological Clinic (Montpellier, France); Biomedical University of California (USA); Los Angeles School of Medicine (USA); Institute of Hydrodynamics (Sofia, Bulgaria); Institute of Gerontology and Cardiology (Kyiv, Ukraine); Institute of Mechanics (Perm, Russia); Children's Cancer Center (Moscow, Russia); Hematology Center (Moscow, Russia); Institute of Transfusion and Hematology (Moscow, Russia); University of Lisabon (Portugal).
 
Modern problems of rheology.
This is a study of the movement of blood in vessels, expression of the role of rheology in disease etiology and pathogenesis, pathological effects on blood flow mechanism and creation of the protocol based on the rheological status. Current issues of modern rheology can only be determined by close contacts with biology, physics, chemistry, cybernetics, and other fields of science and technology.

Problems related to modern rheology as a multidisciplinary science are the following:

1. Study of functions and construction of cells.
2. Study of regulatory functions of cells (intracellular, tissue, regulation of inner organic processes).
3. Rational organization of human life and the problem of life prolonging.
4. Study of the mechanisms of brain activity.
5. The innovative technical design is a study of biological processes in living organisms in order of searching new possibilities for solving problems of a scientific-technical origin (technical or industrial biochemistry, industrial microbiology and biotechnology type). Reproduction of biological processes and organism certain functions, modeling and constructing new technical systems and equipment based on prototypes (Bionic).
6. Rheology astronautics (study of the effects and immediate impact of cosmic space on a living organism, determination of adaptation mechanisms towards cosmic factors, determination of participation of rheology in stress caused by zero gravity).
7. Rheology in pharmacology.
