CYTOECOLOGY

From Big Medical Encyclopedia

CYTOECOLOGY (Greek kytos a receptacle, here — a cell + ecology) — the section of cytology studying adaptive reactions of organisms at the cellular level.

The term «cytoecology» was applied by G. Tischler in 1937.

For identification of mechanisms of adaptation at the cellular level special value has studying of cells of the organisms which adapted to dwelling in extreme conditions: thermophiles, psikhrofil, a drimophilus, barofil, inhabitants of waters with unusual chemical structure. In the presence of toxicants in the environment of a cell can or chemically neutralize these substances, or interfere with their penetration in a cell, changing the physical parameters. At impossibility to protect protoplasm from action of a disturbing factor the cell adapts for it the metabolism. At substantial increase or fall of temperature of the environment, change of humidity, a lack of cell nutrition can temporarily pass into a condition of hypoactivity (hypobiosis) that increases their resistance to action of irritants. The role of cellular adaptation in adaptation of the person and other mammals to various living conditions is still insufficiently studied.
