Abstract

Ganoderma lucidum has been used as a traditional medicinal herb for centuries in China, and its acid extract (ganoderic acid extract, GAE) has shown some antiepileptic effects in the animal models. This was the study of the effects of GAE on the superoxide dismutase (SOD) and mitochondria in cultured primary hippocampal neurons, treated by the Mg2+ free medium, in order to aid our understanding of interactions involving GAE with the epileptiform discharge hippocampal neurons and warrant the experimental aspects for the novel anti-epilepsy agents. The SOD vigour was determined by the xanthine oxidase assay, the variations of mitochondrial membrane potential and cell apoptosis were measured by the JC-1 fluorescent staining and flow cytometry. Our results revealed that the SOD activity and mitochondrial membrane potential (117.68 U/mg pro and 244.08) of the epileptiform discharge hippocampal neurons were significantly lower than the normal ones (135.95 U/mg pro and 409.81), associated with the obvious increase of cell apoptosis (61.39 vs. 28.84). These circumstances can be reversed, with the treatment of GAE (123.86 U/mg pro, 386.92 and 14.37). It indicated that GAE can significantly improve the SOD activity and mitochondrial dysfunction, stabilize the mitochondrial membrane potential, and thereby protect the hippocampal neurons by inhibiting the apoptosis.
