Figure 2. Macrophages in the trigeminal ganglion (TG) on day 5 after inferior alveolar nerve transection (IANX). (A) Photomicrographs of FGlabelled Iba1-immunoreactive (IR) cells on day 5 after IANX. The arrows indicate Iba1-IR cells. Scale bars: 30 μm. (B) The relative area of Iba1-IR cells. Data represent mean±SD. (n=7 each for IANX-treated SAMP8, IANX-treated SAMR1, sham-operated SAMP8, and sham-operated SAMR1 mice; one-way ANOVA with repeated measures followed by Sidak’s multiple-comparison tests, *p<0.05).
