Neuropathic pain is an intractable disease with few definitive therapeutic options. Anethole (AN) has been confirmed to possess potent anti-inflammatory and neuroprotective properties, but its effect on neuropathic pain has not been reported. The present study was designed to investigate the antinociceptive effect of AN on chronic constriction injury (CCI)-induced neuropathic pain in mice. AN (125, 250, and 500 mg/kg) and pregabalin (40 mg/kg) were intragastric administered for 8 consecutive days from the 7th day post-surgery. Behavioral parameters were measured on different days, namely, 0, 7, 8, 10, 12, and 14, from CCI operation. Additionally, electrophysiological and histopathological changes were analyzed on the 14th day. Afterward, immunofluorescence and Western blot were utilized to examine the activation of glial cells and the expression of inflammatory cytokines, respectively. AN treatment of CCI mice considerably alleviated hyperalgesia and allodynia, ameliorated abnormal sciatic nerve conduction, and restored injured sciatic nerves in a dose-dependent manner. Furthermore, AN suppressed the activation of glial cells, down-regulated pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin (IL-6, and IL-1β), and up-regulated the anti-inflammatory cytokine (IL-10). These assays first indicated that AN exerted an antinociceptive effect on CCI-induced neuropathic pain, and might be attributed to the anti-inflammatory and neuroprotective activities of AN.

D020426 Sciatic Neuropathy Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions.
