作者(即上文的第二作者)又利用上文试验的动物(只有35只)进行了不同剂量庆大霉素对前庭毒性的研究。检查了试验动物的椭圆囊斑及其中枢微纹的感觉细胞密度。在对照组末梢与中枢相差不多(22482～23805细胞/mm~2:21370～21963细胞/mm~2),但试验组细胞密度有所下降,且随剂量的增大而加重,中枢损害更明显,如100mg/kg组的动物,椭圆囊斑中枢部的细胞 The authors (ie, the second author above) also conducted studies of vestibular toxicity with different doses of gentamicin using the animals tested above (only 35). The density of sensory cells in the oval plaque and its central line of the test animals was examined. At the end of the control group, it was similar to the central (22482 ~ 23805 cells / mm ~ 2: 21370 ~ 21963 cells / mm ~ 2), but the cell density of the experimental group decreased and increased with the increase of the dose, , Such as the 100 mg / kg group of animals, the cells of the central part of the oval vesicle
