采用透明胶带粘贴法获取蠕形螨，镜下观察不同中药挥发油对毛囊蠕形螨和皮脂蠕形螨的抑杀作用，并设立新肤螨灵软膏为阳性对照、生理盐水为阴性对照，进行体外抗螨活性筛选。

Shigella spp is a kind of Gram-negative bacteria that belong to Enterobacteriaceae family. They cause shigellosis, or bacillary dysentery, an invasive infection of the human colon that affects a spectrum of clinical presentations, from short-lasting watery diarrhea to acute inflammatory bowel disease, the classic expression of shigellosis characterized by the triad of fever, intestinal cramps, and bloody diarrhea with mucopurulent feces.

Sleep-deprivation EEG was performed individually. Results The sleep deprivation EEG showed slow background electric activity in all 3 groups. In addition, the rates of EEG abnormality for nonepileptic seizures group were zero, no statistics were computed because F was a constant. Fifty-seven cases showed spindle/sharp-slow wave complex in suspected epileptic children.

结果 所有病例脑电图的背景电活动频率均明显变慢，非癫癎发作组38例睡眠EEG诱发试验均为阴性，因其诱发试验前后数据一致，故该组无统计意义；拟诊癫癎组脑电图有棘／尖慢复合波等癫癎样放电者57例(559%)；对照组诱发后脑电图异常出现2例(1.9%)癫癎样放电者，3组比较有非常显著差异(x^2=97.3 P0.01)。
