Abstract

Objectives: This study was designed to investigate effects of Gwibitang on the glutamate-induced toxicity of primary rat neonatal astrocytes. Methods and Results: Gwibitang significantly recovered the glutamate-induced apoptosis and inhibited the generation of H2O2 in astrocytes. In addition, both Gwibitang and antioxidants such as GSH protected the glutamate-induced cytotoxicity in astrocytes, indicating that Gwibitang possibly had a antioxidative effect. Moreover, Gwibitang also inhibited the glutamate-induced degradation of Bcl-2 protein and poly(ADP)-ribose polymerase (PARP) in astrocytes. Conclusions: we suggest that Gwibitang has protective effects on glutamate-induced cytotoxicity via an antioxidative mechanism.
