Figure 4.

Effect of microglia inhibitors administered 3 h earlier on B₁R binding sites in the thoracic spinal cord of control and 4-day STZ-diabetic rats. Shown in (A) are autoradiograms of Control (I), Non-specific (II), STZ (III) and STZ + fluorocitrate (IV), and in (B) are the quantification of specific densities of B₁R binding sites in spinal dorsal horn (Laminae I-III). Data are the mean ± S.E.M. of 5 to 6 rats in each group. Statistical comparison to control rats is indicated by **P < 0.01.
