[Role of oxygen-nitrogen stress in neonatal sepsis]

Reference data indicate on the important role of free radicals of nitrogen and oxygen in the mechanisms of the damage of cells and tissues during neonatal sepsis. Meanwhile these connections play an important role in protecting of the host organism from intervention of microorganisms. The aim of the study was the evaluation of peculiarities of oxidizing metabolism and containing of nitrogen oxide. Low consistence of nitrogen oxide and the disturbance of the intracellular oxidative-resorting balance during neonatal sepsis, especially in premature children, induces insufficiency of immune and antioxidant system, which changes the homeostasis and develops the oxidative stress of the host organism. As it was shown by the results of our study, antibacterial and supportive therapy doesn't provide the important reduction of processes of free radical oxidizing. The last circumstance makes a barrier for improving a clinical condition of the newborns.
