Immunological alterations inducible by mercury compounds. II. HgCl2 and gold sodium thiomalate enhance serum IgE and IgG concentrations in susceptible mouse strains.

We determined the levels of total IgE, IgG and IgM in the sera of HgCl2 and gold sodium thiomalate (GST) treated A.SW, C57Bl/6, and DBA/2 mice. In HgCl2 treated A.SW mice, IgE and IgG levels increased up to 30 times above normal. In C57Bl/6 mice HgCl2 induced a slight IgE increase, but no change in IgG. Strain DBA/2, by contrast, did not show significant increases in either IgE or IgG. A.SW mice also proved susceptible to the immunostimulatory effects of GST in that they responded by significant increases in IgE, IgG, and IgM. C57Bl/6 mice responded to GST by an increase in IgM alone, and DBA/2 mice again, were resistant. The same strain-specific responses have been reported with respect to the autoimmunizing effects inducible by HgCl2 and GST.
