Fig. 4. Quantitative summary of glial fibrillary acidic protein staining results from experiments as shown in figure 3. N = 3–4 animals per group; individual values for each animal are shown along with the mean and SEM. Each individual animal value is the average of 20–30 observations. * Relative intensity of zymosan-inflamed dorsal root ganglia (on postoperative day 1, Zym) significantly different from normal dorsal root ganglia and from zymosan-inflamed dorsal root ganglia treated with local eplerenone (Zym + Epl). (ANOVA with Holm-Sidak posttest.)
