Dexmedetomidine to Help Nerve Regeneration in a Rat Sciatic Nerve Injury Model

Figure 5

H&E staining of sciatic nerves in different groups at 6 weeks post nerve injury. The number of axons (yellow marks) was counted in a representative high-power field of the transverse section (×1000). (a) Group 1: surgical incision without nerve injury. (b) Group 2: nerve injury with normal saline injection. (c–e) Group 3: nerve injury with 0.5, 6, and 20 μg·kg⁻¹ DXM injection (groups 3A, 3B, and 3C, resp.).
