Figure 1

Peripheral nerve injury (PNI) increases BSCB permeability. A: Increased permeability to Evans Blue of spinal cord from naïve rats, sham operated rats or rats with chronic constriction injury (CCI, left) or spared nerve injury (SNI, right). Inset: Standard curve of Evans blue and the representative reading of naïve rats or CCI rats. B: Increased permeability to horseradish peroxidase (HRP) following PNI. Left, representative spinal cord sections of HRP extravasation 24 hours after SNI, CCI or naïve rats. Right, histogram showing the integrated pixel density of HRP signaling. Data are presented as mean ± SEM; *p < 0.05 compared to naïve; n = 4-6 per group. All measurements are from lumbar spinal cord ipsilateral to PNI stimulation.
