عنوان انگلیسی The Effect of Ethanolic Extract of Lippia Citriodora on Rats with Chronic Constriction Injury of Neuropathic pain
چکیده انگلیسی مقاله Objective: We examined the protective effects of ethanolic extract of Lippia citriodora in rats subjected to chronic constriction injury (CCI) of sciatic nerve and possible mechanisms of actions. Materials and methods: This study is an original research study. The extract was administered (50, 100 and 200 mg/kg, i.p.) from the day of surgery for 14 consecutive days. The changes in the spinal cord levels of apoptotic factors, microglia and astroglia markers during the time course of study were assessed by western blotting on days 3, 7 and 14 post-CCI. Results: CCI rats developed neuropathy evident from a marked mechanical allodynia, cold allodynia and thermal hyperalgesia on days 3, 5, 7, 10 and 14 post-CCI. A significant increase in the levels of Iba (a marker of microglia activation) and Bax (a proapoptotic factor) was observed 3 days after nerve injury. The levels of Iba remained high on day 7. In contrast, there were no differences in GFAP contents between sham and CCI animals. Treatment with the extract significantly attenuated behavioral changes associated with neuropathy. Bax/Bcl-2 and Iba1 decreased in CCI animals treated with the extract. Conclusion: The results support evidence that microglial activation and apoptosis are correlated with pain behaviors. It is suggested that anti-allodynic and anti-hyperalgesic effects elicited by L. citriodora might have some degrees of association with the inhibition of microglia activation and apoptotic pathways.
