Abstract

Objective: To observe the effect of Qingkailing (QKL) on brain damage induced by glutamate, in order to seek for effective drugs for antagonizing neurotoxicity of glutamate.Methods:The number and morphological metrology of neurocytes in cerebral cortex and hippocampus were detected by MIAS-300 image analyser, electron microscope and immunohistochemical methods.Results: QKL could alleviate the glutamate induced accumulation of water and sodium in brain tissue, relieve the metrological and structural damage of cerebral cells in cortex and hippocampus, reduce the percentage of c-fos positive cell in brain.Conclusion: QKL could protect brain damage induced by glutamate, which might be related to the inhibition of QKL on the enhancement of cfos gene expression induced by glutamate.
