Role of Estrogens in the Size of Neuronal Somata of Paravaginal Ganglia in Ovariectomized Rabbits

Figure 3

Expression of estrogen receptors (ERα and ERβ) in paravaginal neurons of C (a, d), OVX (b, e), and OVX + EB (c, f) groups. Representative photomicrographs showing the nuclear ERα-ir (a–c) and ERβ-ir neurons (d–f). The percentages of ERα-ir (g) and ERβ-ir neurons (h) were similar between groups. Data are means ± SEM (n = 6 per group). One-way ANOVA followed by Newman–Keuls post hoc tests were carried out to determine significant differences between groups. +nf, positive neural fiber; +nn, positive neuronal nucleus; −nn, negative neuronal nucleus; +SGCn, positive satellite glial cell nucleus; −SGCn, negative satellite glial cell nucleus. Bar, 20 µm.
