[A methodological scheme for examination of the urban population, by making multilevel assessments of exposure to ambient air pollutants].

A novel methodological design comprising multilevel assessments of exposures of examinees to controlled ambient air pollution according to the data of route stations was developed to examine the population of large towns. The design was tested in 4 surveys of Moscow residents (apparently healthy and outpatients with a number of chronic diseases). The findings indicate the fundamental possibility of altering the traditional differential design of biomedical surveys of the population, by introducing more evidence-based regression analyses and dividing the contributions of individual chemicals to the observed changes in health indices.

[An automated method of detecting bacteriuria]. / Avtomatizirovannyi metod vyiavleniia bakteriurii.

A screening test for bacteriuria was developed, based on the use of the Bioscreen microbiological system (Labsystem, Finland) and nutrient media manufactured in the USSR. The diagnostic characteristics of the new test were assessed in screening of inpatients; the test has proved to be not inferior to similar methods realized in the microbiological systems manufactured in Western Europe and USA.

[A method of determining Campylobacter pylori in the gastric mucosa in peptic ulcer and chronic gastritis]. / Metod opredeleniia Campylobacter pylori v slizistoi obolochke zheludka pri iazvennoi bolezni i khronicheskom gastrite.

An original method is described for the detection of Campylobacter pylori in gastric mucosa biopsy specimens in chronic gastritis and gastroduodenal ulcers. The method is based on the detection (by a special test) of extremely high urease activity of C. pylori. The method has been employed in examinations of 211 patients. The results and prospects for the use of this technique for the detection of C. pylori in patients with gastroduodenal diseases are discussed.
