Título Changes in humoral immunologic parameters after exposure to volcanic ash
Información bibliográfica Mar. 1983, Vol. 11, No.3, p.395-404. 16 ref.
Resumen 464 loggers occupationally exposed to volcanic ash from the eruption of Mount St. Helens were studied shortly after and one year after the eruption, together with a control group of non-exposed loggers. Complement components C3 and C4 were significantly lower at both examinations in the exposed loggers. Immunoglobulin and antinuclear antibody showed no difference. There was a marked decrease in serum IgG and an increase in IgA levels in the exposed loggers after one year of exposure. Exposure to volcanic ash may affect humoral immunologic parameters. Some of the changes may be related to the presence of free silica.
