[Role of cockroaches Blatella germanica in the development of atopic bronchial asthma]. / Rol' tarakanov Blatella germanica v razvitii atopicheskoi bronkhial'noi astmy.

The results of the development of manufacturing technology for the preparation of allergen from the bodies of cockroaches and the physico-chemical characteristics of this allergen are presented. The complex allergological examination of patients with atopic bronchial asthma revealed that 69.3% of such patients were sensitized to house dust, and in 68.4% of them IgE antibodies to cockroach allergens were detected. Patients with atopic bronchial asthma, not sensitized to house dust, were found to have sensitization to Blatella germanica in 12.2% of cases.

[On sanitary and epidemic situation in the Republic of Ingushetia]. / O sanitarno-épidemiologicheskoi obstanovke v Respublike Ingushetiia.

Information on the recent sanitary and epidemiological situation in the Republic of Ingushetia is presented. In some years an almost twofold growth in the number of population was registered in the republic due to the mass influx of temporarily displaced persons. Such factors as excessive population density, the absence of conditions for the observation of elementary sanitary and hygienic norms, malnutrition, complications with the supply of drinking water meeting sanitary norms contribute to the possibility of epidemic complications. The data on the state of water supply and sewage in populated localities and on the state of morbidity in infectious diseases are presented. By the year 2000 the aggravation of the epidemiological situation in viral hepatitis A and tuberculosis took place. Morbidity in acute enteric infections somewhat increased. There is the danger of the appearance of some infections from the natural foci.

[The guanine content in specimens of house dust collected in the living quarters of healthy persons and of patients with atopic bronchial asthma]. / Soderzhanie guanina v obraztsakh domashnei pyli, sobrannoi v zhilishchakh zdorovykh i bol'nykh atopicheskoi bronkhial'noi astmoi.

The content of insoluble guanine fractions originating from micromites in specimens of house dust, collected in the dwellings of 15 healthy persons with no signs of allergy and 64 patients with atopic bronchial asthma (ABA), was studied. The content of these fractions in house dust in the dwellings of ABA patients was significantly higher than that in house dust in the dwellings of healthy persons (0.76 +/- 0.119 in comparison 0.31 +/- 0.040, p < 0.05). A high content of guanine was detected in house dust of the dwellings of 74.1% of ABA patients and 33.3% of healthy persons, which was indicative of the importance of mite contamination in the formation of ABA.
