NMDA excitotoxicity and free radical generation in rat brain homogenates: application of a chemiluminescence assay.

abstract：:Despite immense advances in the treatment strategies, the effective treatment of patients suffering from neuropathic pain remains challenging. Saikosaponin a possesses anti-inflammatory activity. However, the role of saikosaponin a in neuropathic pain is still unclear. Therefore, the objective of this study was to inv...
