[Changes in the immunological reactivity of young children attending nursery schools with polymer floor covering].
The purpose of this study is to make investigations for establishing the unfavourable effect rate of some of the properties of the synthetic floorings on the immunological reactivity of the organism of children. The health status of 429 children, age 3-5 years from 3 kindergartens in Sofia is traced in dynamic: the control group of 226, attending kindergartens with wood floorings and 203--the test group--attending kindergartens with polymeric floorings. The serum levels of immunoglobulins IgG, IgA, IgM are determined after the radial immunodiffusion method of Maucini. Measures are performed on the microclimatic parameters and electrostatic field as well. The results points out that the morbidity if the test group children is about twice higher in comparison with that of the control group, which correlates with the raised concentrations of the immunoglobulin serum levels. The highest morbidity is from acute respiratory infections and tonsillitis, as a consequence from the deteriorated thermoprotective properties of the synthetic floorings, potentiated under the electrostatic field effect. The results will serve the carrying out of preventive measures for health state promotion of the rising generation.
