ABSTRACT
Aim To investigate effects of tetramethylpyrazine (TMP) on neuropathic pain induced by P2X_3 receptor. Methods Chronic constriction injury (CCI) model was adopted. Mechanical withdrawal threshold and thermal withdrawal latency were measured and P2X_3 immunoreactivity in L_4/L_5 spinal cord was detected by immunohistochemistry. Results At day 14 after operation, the mechanical withdrawal threshold and thermal withdrawal latency in group Ⅴ(CCI group) were lower than those in groupⅠ(NS group),Ⅱ(TMP group),Ⅲ(sham group) and Ⅳ (CCI+ TMP group)(P0.05). The expression of P2X_3 receptor in L_4/L_5 spinal cord of group Ⅳ was lower than that of group Ⅴ (P
