Abstract: HgCl2, added in vitro to human granulocytes in whole blood, caused a marked inhibitory effect on the luminol-dependent chemiluminescence induced by BaS04 crystals in suspension of these cells. The effect was both dose- and time-dependent when BaS04 was used to stimulate the oxidative burst in granulocytes. Incubation with the highest concentration of HgCl2 used [10 mmol/L], however, did not cause disruption of the membranes of granulocytes. The effect of HgCl2 on the granulocytes was irreversible following washing of the HgCl2-treated cells with phosphate buffered saline. HgCl2 did not affect chemiluminescence produced when luminol was excited by oxidative hydrogen peroxide in a cell-free medium. These results suggest that some of the toxicity of HgCl2 may be greater than mediated by an action on the phagocytic immune system
