ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Injection Stauntoniae (IS) on voltage-gated sodium currents in dorsal root ganglion neurons and analyze its pharmacological mechanism of blocking the nerve conduction and anal gesic action.</p><p><b>METHODS</b>Whole-cell patch-clamp recordings were performed in acutely isolated rat dorsal root ganglion neurons and the effects of 10% , 25% and 50 % IS on voltage-gated sodium currents were observed.</p><p><b>RESULTS</b>IS inhibited the peak sodium currents in dorsal root ganglion neurons in a dose-dependent way and affected the activation and inactivation process of the channels.</p><p><b>CONCLUSION</b>The analgesic effect of IS was presumably caused by modulation of voltage-gated sodium channels in primary sensory neurons besides structure destruction of myelin sheath and axon membrane.</p>
