[The effect of benzene derivatives on the body sensitization of children].

The health of children from different districts of the town of Kstov, Nizhegorod [correction of Nizhni Novgorod] Province, that has developed petrochemical industry, was studied. The study demonstrated that the children living in a ecologically poor area had high sensitization to benzene derivatives and a high incidence of allergic diseases. Benzene derivatives, such as trimethylbenzene and tetramethylbenzene), have not only a property of sensitizing, but also nonspecific toxic effects on the children.

[Automated micromethod in the assessment of lysozyme activity].

An automated micromethod for assessment of the lysozyme activity in the blood serum and saliva using a special program is presented. The test is carried out in 96-well polystyrene plates, this helping to save the reagents and spare the test samples without making the assessment less sensitive. The method intensifies the process of measurement, which is particularly evident in prophylactic screening for the detection of groups at risk of body reactivity reduction, local immunity disorders in children and adults, this latter fact being especially valuable.
