Research Abstract

We measured the expression of eight kinds of voltage-dependent sodium channel receptor subtypes (Nav) of the sciatic nerve by the real-time PCR method in sepsis induced critical illness polyneuropathy rat model (L-group) and compared to the control group (C-group). We achieved the results shown the significant reductions of gene expression in three subtypes of Nav and increases in three different kinds of Nav in L-group compared to C-group. These data implied the different types of sodium channel gene expression plays an important role in the mechanisms of pathogenesis of critical illness polyneuropathy as channelopathy.
Since the administration of Drug-X and/or Drug-Y did not improve the alteration in Nav gene expression, other actions of Drug-X and Drug-Y might be involved in the improvement of nerve function during sepsis.
