ABSTRACT
OBJECTIVE@#To investigate the mechanism of hearing pathway NMDAR regulating the changes of phosphorylated c-Jun expression in spiral ganglion after exposed Kunming mice to neural injury noise stimulation to induce permanent or temporary threshold shift.@*METHOD@#To compare the different expressions of the key components (phosphorylated C-Jun) of NMDAR signal pathway during neural injury stimulation by Immunohistochemistry in CG.@*RESULT@#The levels of phosphorylated c-Jun remarkably, increased in the spiral ganglion after 8 h, 48 h, 7 d and 14 d following noise trauma induced permanent threshold shift (PTS), and the numbers of positive cells reduced gradually. The similar changes occur in mice treated with MK-801 30 minutes before and after 3 h trauma induced PTS. After 48 h of noise induced TTS, the expression of Phosphorylated c-Jun return the level of normal control.@*CONCLUSION@#The expressions of phosphorylated c-Jun are time-related and uniform in the time and position in CG after noise trauma. MK-801 can alleviate the damage of noise trauma by altered the NMDA receptor-mediated calcium influx. Therefore, the NMDA receptors may involved in the damage of inner ear in common.
