Abstract

Kada određena supstacija uđe u organizam, njeno toksično delovanje se klinički može manifestovati na razne načine, zavisno od vrste poremećaja prouzrokovanog na nivou ćelije. Vezivanjem za određene endogene molekule, toksična jedinjenja mogu prouzrokovati poremećaj genske ekspresije (neoplazija, teratogeneza), poremećaj tekućih ili trenutnih aktivnosti ćelije (tremor, konvulzije, spazam, aritmija), poremećaj integriteta ćelije (poremećaj sinteze proteina, poremećaj funkcije ćelijske membrane, smrt ćelije) i poremećaj odnosa sa drugim ćelijama (poremećaj u hemostazi – krvarenje). Najteži poremećaji, koji nastaju usled vezivanja hemijskih supstancija sa takozvanim „kritičnim proteinima” (DNK, RNK), klinički se mogu manifestovati kao: mutageneza, karcinogeneza, teratogeneza i imunotoksičnost. When chemical compound enter the body, its toxic effect may clinical to demonstrate in different way, depend from kind of disturbance, what that substance induced in the cell. Binding for endogenous molecules toxic substances can induced disturbance of gens expression (neoplasia, teratogenesis), disturbance of curently activities of cell (tremor, convulsions, spasm, aritmia), disturbance of integrity of cell (disturbance of sinthesis of proteins, disturbance of function of cell membrane, death of cell) and disturbance of relation with other cells (disorders of hemostasis – bleeding). The most serious disturbances which may to begin because of binding chemical substances for so-called “critical proteins” (DNA, RNA) clinical may to demonstrate as: mutagenesis, carcinogenesis, teratogenesis and as immunotoxicity.
