[Estimation of adaptive capacities in Magnitogorsk children from the activity of some detoxification enzymes].
The paper provides the first fragment of a multiparameter study analyzing the influence of environmental pollution, the social and psychological features of a family, and some endogenous factors on genome stability and sensitivity in a developed ferrous metallurgy town. It also gives data on the urine and serum activity of the lysosomal enzyme N-acetyl-b-D-glucosaminidase (NAG) and the serum activity of catalase in an organized contingent of apparently healthy children (n = 178; 6 kindergartens) aged 5-7 years, who live permanently in Magnitogorsk at different distances from the metallurgical works. More than 70% of children selected for examination were found to have average normal levels of activity of the enzymes studied. According to the average levels of enzyme activity, there were only 2 kindergartens (both from the left-bank region). In the children from the left-bank area, enzyme activities varied more greatly, which suggests the higher prevalence of tense adaptation. Correlation analysis revealed association between the children's serum activity of enzymes and some components of snow pollution. It is anticipated that the found changes in serum activities of N-acetyl-beta-D-glucosaminidase and catalase may be determined by individual differences in a child's response to ambient air pollutants.
