Our prospective nonrandomized controlled study enrolled 165 children with acute pneumonia (AP) from 2 to 18 years of age, which included 51 (30.9 %) children with ANP. There were 91 (55.2 %) boys and 73 (44.8 %) girls. Dynamic complex determination of BPI and CRP concentrations in blood serum from children with AP was a sensitive indicator to predict the development of complications and ANP. High levels of BPI and CRP in children with AP were prognostic signs for good outcomes of the disease. In the presence of an initially low BPI level (<10 ng/ml) and high CRP (>100 mg/L), disease progression was noted, which included the development of bronchopleural complications.
Heterogeneity of glass components in slag after nickel acquisition process from Kola Peninsula (Russia)Niejednorodność składników zeszklonego żużla pochodzącego z procesu hutniczego rud niklu z Półwyspu Kolskiego (Rosja)
AbstractThe problem of the disposal of metallurgical slags in the copper-nickel industry also remains open in the Kola Peninsula area, where this kind of exploitation and processing of sulphide Cu-Ni deposits is conducted. The urgent need is to reuse the waste slag heaps through the effective manner of their use based on our available technologies. The slag obtained after processing sulphide copper-nickel ores in the Kola Peninsula contains about 4 wt.% of the ore. The chemical and mineral composition of the slag plays a key role when considering the possibility of its re-use in the context of environmental nuisance. The line of processing Cu-Ni sulfide deposits from the slag proposed by the authors is based on the ability to change the slag phase composition by its oxidation and reduction processes for the enrichment of ore mineralization for reuse.

StreszczenieKwestia utylizacji żużli hutniczych przemysłu miedziowo-niklowego pozostaje otwarta rów-nież na Półwyspie Kolskim, gdzie jest prowadzona eksploatacja i obróbka siarczkowych złóż Cu-Ni. Pilną potrzebą jest ponowne wykorzystanie hałd. W tym celu, przy zastosowaniu dostęp-nych technologii, poddaje się je efektywnemu przetworzeniu. Podczas przetwarzania siarczkowych rud miedzi z niklem w żużlu pozostaje około 4% wag. minerałów rudy. O ponownym wykorzystaniu żużla decyduje jego chemiczny i mineralny skład, który nie może zagrażać naturalnemu środowisku. Zaproponowany przez autorów projekt linii przetwarzania osadów siarczków Cu-Ni z żuż-la zakłada uzyskanie zmiany składu fazowego żużla w wyniku utleniania i redukcji w trakcie obróbki cieplnej, koniecznej do wzbogacenia mineralizacji rudnej, a tym samym do jej ponownego użycia. Słowa kluczowe: metaliczne szkło, żużel, metalurgia niklowa, odsiarczenie

Основным этиологическим возбудителем ГВЗ у детей являлись штаммы Staphylococcus aureus (88,4 % случаев). Встречаемость множественно резистентных штаммов стафилококков и энтеробактерий заставляет обеспечить проведение бактериологического мониторинга отделяемого из ран для своевременной коррекции антибактериальной терапии. Ключевые слова: гнойно-воспалительные заболевания, микробиологический спектр, Staphylococcus aureus, дети Epidemiological study of pyoinflammatory pathogens was conducted among 552 children at the Department of Purulent Surgery of the Regional Children's Clinical Hospital. The main etiologic causative agent of inflammatory lesion in children was Staphylococcus aureus (88.4 % of cases). The occurrence of multiple resistant strains of staphylococci and enterobacteria makes it necessary to ensure the conduct of bacteriological monitoring of the wound fluid for timely correction of antibacterial therapy.
The study determined the etiological structure and sensitivity to antibacterial agents of pathogens of uncomplicated and complicated forms of pneumonia in children treated in a multidisciplinary hospital. According to the study, that timely bacteriological diagnosis in the treatment of pneumonia in childhood with an adequate selection of effective antibacterial agents helps reduce hospitalizations and the development of complicated forms of pneumonia.
