From: Delayed sympathetic dependence in the spared nerve injury (SNI) model of neuropathic pain
Effect of chemical sympathectomy on the development of neuropathic pain-related behavior induced by SNI. A. Paw withdrawal thresholds to mechanical stimuli using a calibrated series of von Frey hairs were not different between chemically sympathectomized group (sympX, n = 6) and vehicle treated group (control, n = 6) before and after SNI. B. Response to cold using an acetone drop was similar before SNI in both groups. No overall effect was demonstrated, except at the latest time point studied (* p < 0.01). C. Mechanical hyperalgesia evoked by pin prick showed no difference between groups.
