ABSTRACT
During the treatment of children with impaired nasal breathing (INB) cooperation of medical specialists is needed in order to reveal risk factors. The objective of the study was to prove the necessity of complex approach to the treatment of children with risk factors for INB. Multi-variant analysis of somatic and dental health of 170 children aged 4-6 was performed. The dental health was examined gradually in several steps, including physical examination. The following risk factors of antenatal and postnatal development of a child were revealed: genetic predisposition, complication of pregnancy, birth defects, somatic pathology, mastication dyspraxia, respiratory impairment, and various speech impediments. The following dentofacial anomalies prevailed: disorder of abrasion of primary dentition tubercle, development discord of cranio-facial area. The necessity of doctors' cooperation was proved during the treatment of children with impaired nasal breathing. Accurate execution of proposed treatment schemes allows eliminating risk factors promptly and decreasing the pathology severity.

The elemental compositions of cells of representatives of five bacterial genera (Hyphomonas vulgare NP-160, Caulobacter bacteroides NP-105, Flectobacillus major Mm, Escherichia coli, and Spirulina platensis) was studied by electron microscopic x-ray microanalysis. The contents of P, S, Cl, K, and Ca were determined. The bacterial species studied in this work substantially differ by the contents of these elements. A high content of K is typical of S. platensis, whereas F. major, an aquatic form, is rich in Cl. The other bacterial species were had the levels of K, Ca, and the K/Ca index, which correlated with the stability of their cell membranes and resistance to stress. In E. coli, the spectrum of the elemental composition and the values of P/S and K/Ca are indicative of high energy potential and low tolerance of membranes.
