Mice were injected subcutaneously with anti-MIP-2 MAb at 10 μg/day (group 2) and at 100 μg/day (group 3) on days 0 to 5. Subsets of mice were killed on days 7 and 14. The BW and HW/BW ratio were calculated. The percentages of positively stained mononuclear cells were calculated as previously described (16, 17). Myocardial virus titers were determined by a plaque assay. Values are means ± standard deviations. ∗ and ∗∗, P < 0.05 and P < 0.01, respectively, versus control.
