[Influence of oxidative stress on tissue regeneration].

The redox reactions involving oxidants and antioxidants play a key role in many biochemical pathways and cellular biosynthesis and regulation processes at the molecular level. Normally, there is the balance between oxidative and reductive processes in the organism. If oxidative processes are prevalent, it will result in oxidative stress. It leads to damage of many biological structures, resulting in impairment of many processes at the molecular level. Lipids and proteins are most sensitive to oxidative stress structures. Lipid oxidation can result in degradation of the cell membrane, whereas the oxidation of proteins can result in a change of their properties. It is suggested that oxidative processes accompany inflammation and affect their growth. This situation can lead to a number of serious diseases such as tumors. Many scientists claim that oxidative stress causes many pathological conditions. Enzymes and antioxidants, which are one of the body's defenses, can prevent oxidative processes.
