The present study was undertaken to explore the role of gamma-aminobutyric acid transporters in the neuropathic pain. On the chronic constriction injury (CCI) rats 4 doses (5, 10, 20, 40 microg in group N5, N10, N20, N40, respectively) of specific gamma-aminobutyric acid transporter-1 inhibitor NO-711 or normal saline (in group NS) were intrathecally administered before sciatic nerve ligation (pre-treatment) or at the third day after ligation (post-treatment). The paw withdrawl latency (PWL) from a noxious thermal stimulus and paw withdrawl mechanical threshold (PWMT) of von Frey filament was used as measure of thermal hyperalgesia and tactile allodynia respectively. The results demonstrated that post-treatment of NO-711 significantly suppressed thermal hyperalgesia and allodynia in CCI rats (P<0.05, P<0.01), the inhibitory effect lasted for 2 h (N40 group) and 4 h (N20 group) respectively. NO-711 inhibited thermal hyperalgesia induced by CCI in a dose-dependent manner. Intrathecal pretreatment with different doses of NO-711 delayed the occurrence of thermal hyperalgesia, but could not delay the emergence of allodynia induced by CCI. This study indicates that gamma-aminobutyric acid transporter inhibitor has anti-thermal hyperalgesia and anti-tactile allodynia effects in neuropathic rats.
