Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.
