对以头颈部和五官症状为首发症状而到我科初诊的16例重症肌无力患者进行纯音测听和声导抗检测，并在肌肉注射甲基硫酸新斯的明0.5～1.0？mg，30？min后复查声反射。检测用0.5、1.0、2.0和4.0？kHz的纯音作同侧和对侧刺激，比较用药前后有无声反射及其阈值、振幅变化、有无衰减等。

After mixing benzonitrile with anhydrous ethanol, we have also measured their vibrational dephasing time.

The resistance the isolated strains to chloromycetin and erythromycin were significantly increased, and that to vancomycin, penicillin, ampicillin, gentamicin, nitrofurantoin and levofloxacin were not varied markedly.

而对万古霉素、青霉素、氨苄西林、庆大霉素、呋喃妥因、左氧氟沙星的耐药性无明显改变。结论 10年后肠球菌的耐药性发生了变化，对一些抗生素的耐药率均有增升。

The results indicate that the vertical component of wind velocity variance remains unchanged but the hori- zontal component increases as the sampling length increases.

结果表明：在进行湍流统计特征量计算过程中，采样长度增加时，垂直分量风速方差无明显变化，水平分量风速方差增大；随着风速的减小以及稳定度参数 z/L的增加，采样长度对计算结果的影响变得更为突出。

They found that the degree of corrugation in the lead layer changes with temperature in precisely the way expected for an ideal system with no defects.

他们发现铅层的褶皱程度正如一个理想的无缺陷系统一样随着温度改变而精确的变化着。

In autumn,there were GTH1 cells and GTH2 cells in GTH cells. A large number of secretory granules in GTH1 cells were circumnuclear; In GTH; cells cytoplast,there were two types of secretory granules,small circle and large circle, in small number.Structure of STH cells had no obvious changes.

秋季，在GTH细胞中发现GTH_1和GTH_2两种细胞，GTH_1细胞具有大量的分泌颗粒，并呈围核分布，GTH_2细胞胞质中具有数量较少的小圆形分泌颗粒和大圆形颗粒；STH细胞的结构无明显变化。

In addition, the mitochondria showed no signs of swelling and the nuclear membrane remains intact. Multiple membrane-bound apoptotic bodies and engulfment of cell debris and corpses by phagocytes were observed at 24h, while extensive cell loss appeared at 48h. These results demonstrated the occurrence of high level of apoptosis by 24h postdosing.

相应的超薄切片在电子显微镜下得到结果与光镜下一致，24h前线粒体形态结构无明显变化，主要有染色质浓缩、边集及分割，以及内质网空泡化和凋亡小体的形成；24h后可观察到线粒体的肿胀和扩张，细胞发生崩解和死亡。
