ABSTRACT

Objective:

To study the role of tetrodotoxin-resistant(TTX-R)human sodium channel of hNa v1.8 mRNA in trigeminal neuralgia (TN).

Methods:

The samples of affected trigeminal division(inferior alveolar nerve) and non-affected division(lingual nerve) were surgically obtained from six idiopathic TN patients to whom the drug therapy was not effective.The expression of hNa v1.8 mRNA was assessed by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) with ?-actin as an internal control. A sample of great auricular nerve (from a patient who had to accept the combined radical neck dissection with glossectomy and hemimandibulectomy) and a sample of infraorbital nerve (from a patient who had to accept subtotal resection of maxilla) were used as the negative controls. ResoultsThe relative amount of hNa v1.8 mRNA in the affected trigeminal divisions(1.233?0.324) was higher than that in the non-affected divisions(1.018?0.249), t=3.919,P=0.011.

Conclusion:

The higher expression of hNa v1.8 mRNA in the affected nerves of TN patients may play an important role in TN.
