| Research Abstract |
I detected up-regulations of many gene expressions in trigeminal ganglion of inferior alveolar nerve (IAN) transaction model rat, one of many neuropathic pain model. The allodynia was inhibited by an anticonvulsant, gabapentin, which was infused to medullary through an indwelling catheter. Although many genes were up-regulated in the trigeminal ganglion of the IAN transacted rats, only the up-regulated expression of CACNA2D1, a subunit of voltage-dependent calcium channel, was reversed by gabapentin, along with inhibition of allodynia.
