Abstract

Susceptibility to murine cytomegalovirus (MCMV) was enhanced by treating B6C3F1 and CD-1 mice subcutaneously with 100 mg 7,12-dimethyl-benz[a]anthracene (DMBA)/kg fractionated over a 2 week period prior to sub-lethal infection. Virus-augmented natural killer cell (NKC) activity was depressed in B6C3F1 mice treated with 100 mg DMBA/kg, while serum interferon (IFN) levels were unaffected. Treatment with 50 mg DMBA/kg had no effect on susceptibility to virus or virus-augmented NKC activity. Susceptibility to MCMV was not affected by treating mice with 400 mg benzo[a]pyrene (B[a]P)/kg using the same exposure regimen. Virus-augmented NKC activity was suppressed in B[a]P-treated mice, but the magnitude of the suppression (18%) was much less than that for DMBA-treated mice (39%). Susceptibility to MCMV, virus-augmented NKC and IFN induction were not affected in mice treated intraperitoneally with 50 mg cyclosporin A (CSA)/kg/day for 5 days and infected on the 5th day of treatment. In contrast, enhanced susceptibility to MCMV and depressed NKC activity were observed in mice treated by the same exposure regimen on days 1-5 post infection. Susceptibility was not affected by CSA given on days 5-9 post infection. The data are useful not on...Continue Reading
