From: Distinct degree of radiculopathy at different levels of peripheral nerve injury
A. Iba1 positive microglia in laminas I–II of the injured L5 segmental level: Activated microglia in the nerve injury groups (C, D, E) were observed, compared with the normal (A) and sham group (B). B. The total number of microglia in laminas I–II of the injured L5 segmental level : There was no significant difference in the number of activated microglia between groups A and B. The nerve injury groups (C, D, E) were more sensitive than the sham group (*P < 0.001), with significant differences between C, D and E (**P < 0.001).
