In four areas with different types of atmospheric pollution 534 children of school age were examined for serum immunoglobulins (IgG, IgA, IgM and IgE), saliva IgA (sIgA), lysozymes (LYS) and acute phase reactants (alfa-l-antitrypsin - A1AT, alfa-2-macroglobulin -A2M, ceruloplasmin -CPL, transferrin - TRF). The children were divided into two groups: those with altered resistance (AR) comprising allergoses of all types and recurrent or persistent infections and those without the above health problems, i.e. healthy (H). There were more children with AR in areas with higher atmospheric pollution than in control areas. The frequency of AR was higher among boys than among girls. In the control area BN, a number of parameters in the AR group differed significantly from those in the H group. In areas with substantial atmospheric pollution these differences were generally less pronounced. Significant differences were found between the control and polluted areas in many indicators. In the area KO characterized by an intermediate degree of industrial pollution the means of the tested parameters were habitually elevated, whereas in the heavily polluted areas they were decreased. The most sensitive tests for evaluating differences between the areas were the levels of A1AT, LYS, and IgE, while the variations of sIgA, sLYS and CPL were less pronounced.

In autumn and spring a group of 132 ten-year-old school children (54.5% from families of smokers) were examined for blood content of immunoglobulins (IgG, IgA, (gM, in autumn including also IgE), lysozyme (LYS) and the so called acute reactants (alpha-1-antitrypsin = A1AT; alpha-2-macroglobulin = A2M; transferrin = TRF; ceruloplasmin = CPL); and for saliva sIgA and sLYS. Autumn examination detected significantly higher mean values of IgE in children from families of smokers, while other mean differences remained insignificant. Spring examination revealed significant differences in the means of IgA levels children from families of smokers (FS) had significantly lower levels of IgA while their saliva sIgA values were significantly higher. Mean spring CPL levels in FS were significantly higher. Analysis of distribution curves of autumn examination showed a significant shift of A1AT towards higher values in boys from FS. Girls from FS exhibited a shift of LYS towards lower values. Spring examination in boys FS evidenced a shift of CPL and sIgA values towards higher values; the curve of serum IgA levels split distinctly into two subgroups. In girls from FS the only change observed during the spring examination was a shift of A2M levels towards higher values with an indication of a split. To conclude, passive smoking in school children is responsible for a number of significant changes, the latter being more frequent and marked in spring when the children's organism is weakened by many other unfavourable circumstances. More significant changes were seen in boys.

The prevalence of respiratory diseases was followed in a group of 80 children (39 boys and 41 girls) of mean age 12.4 +/- 0.9 years during the part of school year (November - May incl.). The specimen of blood was taken from all studied children before the study started and the values of nine serum proteins were measured (IgG, IgA, IgM, IgE, alfa 1-antitrypsin = A 1-AT, transferrin = TRF, ceruloplasmin = CPL, alpha 2-macroglobulin = A 2M, lysozyme = LYS), as well as levels of two secretory proteins in saliva (sIgA and sLYS). The difference between the subgroup of boys, who fall into some respiratory illness during the observation time, and those who remain healthy, did not reach the level of significance. In contrast, the girls subgroup revealed significantly higher respiratory morbidity. With those girls, who remained healthy, the levels of serum IgE were highly increased and A 1-AT level weakly increased compared to ill girls. The level of TRF and CPL were significantly decreased with the healthy girls.

All organisms are protected from harmful reactive oxygen which is produced also under physiological conditions by a complex antioxidative system. Our work was aimed at the ascertainment of the level of reduced and oxidated glutathione in erythrocytes of healthy people, the concentrations of ceruloplasmin (GSH) and transferrin (GSSG) in the serum, as well as the investigation of the relationship to antioxidative enzymes ---Cu, Zn-superoxide dismutase (SOD), catalase (CAT) and Se-glutathione-peroxidase (GPx) in erythrocytes. We discovered a mutual direct linear correlation between the levels of GSH, GSSG, CPL and TRF, indirect linear relation between the concentrations of TRF, GSH, GSSG and activities of SOD and GPx, between the concentrations of CPL and GPx activities, and a direct linear relation between concentrations of GSH and TRF with CAT activity. The results indicate to a mutual dependence of investigated nonenzymatic antioxidative factors and antioxidative enzymes. (Tab2, Fig. 4, Ref.13.).

The accumulation of damage to cellular biomolecules, including DNA, over time may play a significant role in the aetiology of the ageing process. We have previously quantified DNA damage and mutation within cultured lymphocytes from healthy human male subjects in three different age groups (35-39, 50-54 and 65-69 years). The results of that study showed an age-related increase in DNA damage and mutations in lymphocytes. In addition, an age-related decrease in the capacity of the lymphocytes to repair H2O2-induced DNA damage was found. In this article, we report the findings of an extension to the earlier study. Thirty-one generally healthy male and female subjects between the ages of 75 and 80 years were recruited. Using a number of bioassays, we were able to determine; basal levels of DNA damage (for 18 subjects) and mutant frequency at the hypoxanthine phosphoribosyltransferase (hprt) gene locus (for 16 subjects) within cultured lymphocytes. In addition, in vivo antioxidant status (for all study subjects) and the capacity of lymphocytes to repair H2O2-induced DNA damage (for 18 subjects) were also assessed. The results obtained showed: that the mean basal level of DNA damage in lymphocytes from subjects in the 75- to 80-year age group (12.6 +/- 4.7%) was similar to that of the 35- to 39-year age group (13.3 +/- 3.3%), p = 0.42 (Mann-Whitney); there was no significant difference between log mean mutant frequency at the hprt gene locus in lymphocytes from the 75- to 80-year age group (0.31 +/- 0.33) compared to that observed in the 35- to 39-year age group (0.24 +/- 0.21; Student's t-test, t = 0.68, p > 0.05). Levels of the antioxidants glutathione peroxidase (GPx EC 1.11.1.9), catalase (CAT; EC 1.11.1.6) and caeruloplasmin (CPL; EC 1.16.3.1) were significantly elevated in the 75- to 80-year age group, compared to the 35- to 39-, 50- to 54- and 65- to 69-year age groups. Levels of bilirubin (BR) were reduced in the 75- to 80-year age group, the decrease being contributed by the female subjects. No differences in levels of superoxide dismutase (SOD; EC 1.15.1.1) or uric acid (UA) were found between the 4 age groups. Following treatment of lymphocytes with H2O2, we did not find any difference in the susceptibility of lymphocytes to DNA damage in the 75- to 80-year age group, compared to the other age groups. The DNA repair capacity in lymphocytes from individuals in the 75- to 80-year age group was similar to that of the 35- to 39-year age group, for all time points assessed. These results highlight the importance of DNA repair processes and antioxidant defence systems for maintaining genomic stability in vivo.
