Objective : The water extract of Yukgunja-tang(YGJT) has been traditionally used in treatment of qi deficiency and phlegm in Oriental medicine. However, little is known about the mechanism by which YGJT protects neuronal cells from injury damages. Therefore, this study was designed to evaluate the protective effects of YGJT on C6 glial cells by glutamate-induced cell death. Methods : The present study describes glutamate, which is known as an excitatory neurotransmitter, related with oxidative damages, and YGJT, which shows protective effects against glutamate-induced C6 glial cell death. One of the main mediators of glutamate-induced cytotoxicity was known on the generation of reactive oxygen species(ROS) via activation of NADPH oxidase (NOX). The protective effects of antioxidant(NAC) and NOX inhibitor(apocynin) on the glutamate-induced C6 glial cells were determined by a MTT reduction assay. Result : YGJT inhibited glutamate-induced ROS generation via inhibition of NOX expression on glutamate-stimulated C6 glial cells. Furthermore, YGJT attenuated glutamate-induced caspase activation. These results suggest that YGJT could be a new potential candidate against glutamate-induced oxidative stress and cell death. Conclusion : These findings indicate that in C6 glial cells, ROS plays an important role of glutamate-induced cell death and that YGJT may prevent cell death from glutamate-induced cell death by inhibiting the ROS generation.
