title: Changes in stable metabolites of nitric oxide in children-residents of radioactively contaminated territories.
abstract: Objective. An evaluation of the changes in nitric oxide system by the level of its stable metabolites in the blood serum and their comparison with content of 137Сs in the body of children-residents of radioactively contaminated territories. Materials and methods. The children of school age, the residents of radioactively contaminated territories were examined. The levels of nitrogen compounds (NO2- and NO3-) were determined by the standard method using Grissreagent. 137Сs content was determined in the children body by whole-radioactive body counter. Results. Studies of nitric oxide metabolite content in the blood serum revealed the decrease in nitrite level under an absence of the significant changes in nitrate content and sum of NO metabolites in the children-residents of radioactively contaminated territories. An increase in 137Cs content in the body was accompanied by a decrease of nitrite level in the blood serum of a significant part of children.
