Features of disturbance of oxidative stress markers and venous blood cells apoptosis in the early stage of acute poisoning by corrosive substances

The character of disturbance of oxidative stress markers and venous blood cells apoptosis in patients with corrosive substances poisoning in early stage was studied. In the first 5 days for the estimation of the oxidative stress severity the lipid peroxidation (LPO) products, antioxidant system (AOS) state and value of the platinum electrode open circuit potential (OCP) were determined. Apoptosis was studied by measuring of apoptotic lymphocytes and dead leukocytes concentration. It was found that in patients younger than 60 years in response to the intake of corrosive substance, peroxidation processes are the first to activate, as evidenced by the oxidative stress development and its increase in dynamics. The apoptosis processes are activated only as oxidative stress severity increase which indicates the development of an adequate reaction to the acute chemical trauma in persons of working age. Contrariwise, in patients older than 60 years apoptosis of venous blood lymphocytes is first activated followed by peroxidation processes activation. Moreover, the low activity of LPO/AOS system is noted in the whole. This fact indicates the absence of an adequate reaction to the intake of corrosive substance in this category of patients.
