The aim of this study was to investigate whether intracisternal administrations of triptolide and N-nitro-L-arginine Methyl Ester (L-NAME) are involved in the regulation of temporomandibular joint (TMJ) pain. The TMJ pain was induced by the injection of 5% formalin (30 ¥ìl) into TMJ capsule of rats. The pain behavioral responses was recorded the number of grooming or scratching on the left TMJ area for 9 successive 5 minutes intervals. Triptolide and L-NAME were administrated intracisternally 10 minutes before formalin injection. The intra-articular injection of formalin produced a biphasic pattern of pain response (first phase: 0¡­10 minutes and second phase: 11¡­45 minutes). The intracisternal administration of triptolide (1 ¥ìg/10 ¥ìl) and L-NAME (0.1 ¥ìg/10 ¥ìl) suppressed the TMJ pain behavior in each experiment. Co-administration of two drugs was shown the enhanced effect than the analgesic effect by single-administration of triptolide (1 ¥ìg/10 ¥ìl). The triptolide could be a useful analgesic agent for the treatment of TMJ pain, and it is expected to reduce the substantial amount of it via co-administration of synthetic chemical compound and natural products.
