[Inhomogeneity of control samples as the reason for additional variations in the spontaneous level of chromosome aberrations in a human lymphocyte culture].

The results of population cytogenetic studies performed by a standard technique in one laboratory during 1987-1992 are summarized. Variations in the rate of spontaneous chromosomal aberrations were found in lymphocyte culture derived from individuals employed in the nonindustrial sphere and in the administrative sector of the chemical industry. The proportion of cells with chromosomal aberrations is 1.

[Cytogenetic screening of workers of rubber manufacturing industry].

Cytogenetic analysis of lymphocytes was performed in 36 preparatory workers engaged into rubber shoes and general mechanical rubber goods production. Preparatory workers and management staff had the same chromosomal aberrations frequency. Although chromosomal aberrations frequency in employees of the enterprise appeared to be twice as much as that for general population, which proves hazardous factors of rubber production to afflict genofond of employees.

[Cytogenetic analysis of the peripheral blood lymphocytes in people residing in regions of the Kaluga Oblast polluted with radionuclides].

In order to reveal possible genetic effects of the Chernobyl accident for human populations, a cytogenetic survey of 33 agricultural workers from 2 areas of the Kaluga Region with different radiation backgrounds (villages of Mladensk and Ogor) was conducted in 1989. At the time of investigation a dose of 137Ce for Mladensk was 3.7 ci/km2, that for Ogor--1.

[Cytogenetic examination of workers engaged in manufacturing of asbestos technical products].

The article contains data on a cytogenetic monitoring of workers engaged in asbestos production, depending on duration of professional service and degrees of dust contamination of the air. The results of the cytogenetic analysis of the peripheral blood lymphocytes in 31 workers revealed the average rate of aberrant cells 1.78% in workers with professional service below 1.
