Mice were fed soy isoflavones (IF; 0, 126 or 504 mg aglycone equivalents of IF/kg diet) for 14-days prior to and during a 30-day exposure to LPS (1.33 μg/d). TNF-α expression was determined immunhistochemically. Chi-square analysis was performed on the % of cells expressing TNF-α and the intensity of expression. The overall score was calculated. Results for the overall score are expressed as means ± standard error. Values for a given parameter that share the same superscript letter are not statistically different (P > 0.05) from each other. P-value for LPS*Diet on overall scores is < 0.0001.
