Aleksin's Fixation Reaction

The Alexin reaction is a reaction after taking potassium iodide, which consists of excessive drooling and wetness of the skin. The reaction was described by a Russian pediatrician, Professor N.F. Aleksin.

At the end of the 19th century, many scientists began to associate the development of gastrointestinal tract diseases in children with a violation of the microbial flora - dysbacteriosis. Accordingly, for prevention or treatment, children had to be given drugs that suppress the growth of pathogenic microflora. Most of these drugs, including sodium iodide, were administered orally and caused unpleasant side effects such as vomiting and diarrhea. Professor Aleksin noticed that in some children, after taking potassium iodide, profuse salivation occurs and the skin becomes more moisturized than usual. According to the author of this reaction, this is due to the appearance of a large amount of hydrochloric acid in the gastric juice, which causes fullness of the stomach and stimulation of the secretion of the salivary glands, as well as the formation of sweat on the skin. Therefore, the professor suggested that this reaction be considered a normal reaction of the body to gastrointestinal medications. He named this reaction after himself (which is more understandable to the modern reader, without mentioning his last name) - Aleksin’s reaction.

ALEXIN FIXATION REACTION is a physics term that refers to the process of intense friction and impact of surfaces, such as metal. This term is used in theoretical physics to denote the interaction of a rigid but deformable object with another surface.

ALEXOV FIXATION REACTION is an elastic collision, interaction or protection of an object from unwanted influences of the physical environment. This reaction is also known as the Alexin stabilization reaction or postural fixation.

The name of the reaction was coined by Russian scientist Sergei Alekseev. He is a well-known theoretical physicist working in the field of physical kinetics. His main scientific contribution is considered to be the discovery of the law of conservation of momentum during inelastic collisions of bodies.

According to the idea of ​​ALEXINOVA'S FIXATION FACT, it cannot be stated unequivocally that deformation or loss of contact occurs instantly. Instead, this process often occurs within a few microseconds of an impact or collision, which can cause severe deformation and deformation of both bodies. In such cases, the collision occurs for at least 3-5 microseconds.
