RESUMEN
AIM: To estimate the prevalence of bronchial asthma (BA) basing on the complex of the disease symptoms within the last year associated with bronchial obstruction (BO) and bronchial hyperreactivity (BHR). MATERIALS AND METHODS: A questionnaire survey (IUATLD) has covered 1572 individuals (mean age 40.1 +/- 0.3 years, 837 females). The responders were divided into 3 age groups. BO and BHR were examined, concentration of air pollutants NO2, SO2, CO were measured. RESULTS: The most typical BA symptoms were defined in males and females in different age groups. The relationship between frequency of BA symptoms on concentration of air pollutants was determined. BO and BHR were found in 13.3% of the respondents. CONCLUSION: Prevalence of BA in a large industrial region is 16.4% (17.5% in males and 14.0% in females).

A combination of laboratory tests, providing the most valuable quantitative assessment of hepatic function at large was selected with the aid of an EC-1020 computer on the basis of the investigation of 124 hepatic patients and 15 normal subjects. This combination was termed the hepatic functional index (HFI); it was determined by the PTI (prothrombin index) to RETk (blood Bengal rose retention) ratio, expressed as a percentage. Quantitative criteria of normal and abnormal hepatic activity, with subdivisions by severity, have been proposed on the basis of HFI estimations in patients with varying degrees of hepatic failure and in normal subjects.

An account of the findings resulting from the study of experimental poliomyelitis in M. rhesus after several immunizations with Sabin live vaccine is given. The challenge of the vaccinated monkeys with the virulent strain of poliomyelitis virus, type I, was shown to result in the development of a disease with clinical and morphological characteristics typical of poliomyelitis in some of these monkeys. The incidence of the infection was found to decrease with the growth of antibody level in the blood of the monkeys. The virus was isolated from the tissues of the vaccinated animals showing the symptoms of the disease less frequently than from the tissues of the control animals.
