利用超微结构和细胞化学的方法研究庆大霉素中毒的豚鼠前庭暗细胞区,发现黑素体数量增加,暗细胞仍有调节内淋巴作用,对三磷酸腺甙钠、钾酶的活性影响不大。取9只400～450克豚鼠,分为A、B组和对照组。A组按每天100mg/kg庆大霉素肌注,持续15天;B组按每天150mg/kg,持续5天;对照组不用药。 Using ultrastructural and cytochemical methods to study gentamicin poisoning guinea pig vestibular dark cell area, found that the number of melanosomes increased, dark cells still regulate endolymphatic, the impact of adenosine triphosphate sodium, potassium activity Not big. Take 9 400 ~ 450 g guinea pigs, divided into A, B group and control group. Group A was treated with 100 mg / kg gentamicin intramuscularly every day for 15 days. Group B received 150 mg / kg daily for 5 days. In control group, no drug was used.
