Effect of short exposure of C57Bl/6 and F1/NZB x C57Bl/6/ mice to i.p. injected chrysotile A on YAC-1 cytolytic potential (NK cell function) of spleen cells was investigated. It was found that 3 days after injection, cytolytic activity of spleen cells was significantly abrogated and this was paralleled with an increase of alpha-naphtyl acetate esterase positive cells/macrophages in spleen cell population. In addition, effect of exposure of mice to i.p. injected chrysotile A coated with benzo(a)pyrene (BaP) was investigated. BaP did not modify the abrogative effect of chrysotile A on NK cell function. Asbestos fibres themselves were sufficient for depletion of NK cell function of spleen cells.
