HLA and antinuclear antibody incidence in asbestos workers.

The incidence of antinuclear antibodies (ANA) in asbestos textile workers was compared with the results of HLA typing. HLA B8 antigen was more frequent in the ANA-positive group as compared to the ANA-negative group. The relative risk of this associati-n is 2.

Preliminary testing of DRw antigens in a Polish population.

B lymphocyte subpopulations taken from 89 individuals were investigated with 180 sera from the seventh Histocompatibility Workshop. The results obtained served in determining the frequency of 8 DRw antigens in a tested population sample. Their incidence was comparable to the frequencies determined during the Workshop for the reference group of European Caucasoids.
