Toxicity Selective

Selective toxicity

Selective toxicity (S) is a form of toxicity in which only certain biological structures of the body are affected. It differs from ordinary toxicity in that it affects only certain organs or tissues without affecting others. Selective toxicity can be caused by various factors such as chemicals, viruses, bacteria, toxins, etc.

Selective toxicity can occur in different forms. For example, some chemicals may only affect certain tissues or organs, such as the lungs, liver, or kidneys. In other cases, the virus or bacteria may only infect a specific type of cell, such as lymphocytes or red blood cells.

One of the best known examples of selective toxicity is the effect of antibiotics on bacteria. Some antibiotics may only work on certain types of bacteria, while other antibiotics may be effective against a wide range of bacteria. This is due to the fact that each type of bacteria has its own structural and metabolic characteristics that make it vulnerable to certain antibiotics.

Additionally, selective toxicity can also be caused by natural processes in the body. For example, certain hormones or neurotransmitters may act only on a certain type of cell or tissue, regulating their function.

While selective toxicity has its benefits, it can also cause serious problems if not properly managed. For example, if an antibiotic only works on a certain type of bacteria, other bacteria may become resistant to that antibiotic, causing treatment to fail. In addition, the selective action of some toxins can lead to damage to certain organs or tissues, which can cause serious complications.

Overall, selective toxicity is an important factor to consider when treating diseases. However, to effectively combat it requires a deep understanding of the mechanisms of its action and the characteristics of various organisms.

**Selective toxicity (TS) is a toxic effect on biological structures, manifested by damage only to certain organs and tissues (cells and their structures, animal tissues, organs or organs of an intact organism).

Definition of the term "toxicity"

The term toxicity, as defined by D. S. Sarkisov and E. A. Kolesnikov, denotes “a complex of interactions between organisms - producers, consumers, including humans, and their environment.”

The interaction between an organism and its environment consists of many factors that determine these relationships at all levels of the structure and functioning of the organism. Most of them are a manifestation of the harmful effects on the body of a number of substances found in the biosphere, causing negative changes in it, called pathological adaptive reactions or actions. These phenomena are the result of an adaptive process that adapts the body to
