摘 要:目的研究褪黑素(melatonin,MLT)对庆大霉素(gentamicin,GM)耳毒性的拮抗作用.方法实验分为GM组、MTL+GM组及生理盐水对照组,采用豚鼠畸变产物耳声发射(distortion product otoacoustic emission,DPOAE),观察用药后DPOAE幅值及I/O曲线斜率的变化.结果 GM组用药后3、4、6、8 kHz DPOAE幅值同对照组相比有显著性差异(P<0.01);I/O曲线斜率变小,在4、6、8 kHz与对照组相比有显著性差异(P<0.01).GM+MLT组用药后各频率段DPOAE幅值,与对照组相比无显著性差异;I/O曲线斜率无明显改变,同对照组相比无显著性差异(P>0.05).结论 MLT能有效拮抗庆大霉素的耳毒性作用.
