作者用100dB SPL频率4kHz的脉冲噪声刺激24只豚鼠6小时。噪声发自MA-31测听器,给声和间歇时间均为200ms。动物均分成四组,前三组受声刺激,第四组做对照。第二组在接受声刺激前腹腔注入磷酸肌酸50mg/kg,第三组同法注入苯妥英钠5mg/kg。所有动物在麻醉下被取下颞骨,脱钙后制成连续切片,染色 The authors stimulated 24 guinea pigs for 6 hours with 4 kHz impulsive noise at 100 dB SPL frequency. Noise from the MA-31 hearing aids, to the sound and intermittent time is 200ms. Animals were divided into four groups, the first three groups by acoustic stimulation, the fourth group as a control. The second group received intraperitoneal injection of phosphorylated creatine 50 mg / kg before receiving acoustic stimulation and the third group received phenytoin 5 mg / kg. All animals were removed under anesthesia temporal bone, decalcified into serial sections, stained
