Objective Ketogenic diet is a high fat, low protein, low carbohydrate diet.

目的 生酮饮食是一种高脂肪、低蛋白、低糖饮食，它对癫癎特别是难治性癫癎的临床疗效早已明确，但其抗癎作用机制尚不清楚，长期应用生酮饮食对发育期脑认知功能的影响目前也无定论。

There was not significant difference in patients with epilepsy, cerebral palsy, febrile convulsion or Tourette syndrome.

极度纺锤波是一种非特异性的异常脑电现象，无病因学方面的差异。

The multi-channel VEPs curves and topography with"average reference"transformed data could accurately discribe the brain activity polarity and strenth in different space without significant effect on the configuration of the topography.

用&平均参考&处理后的数据所绘多导VEPs及地形图，能准确地表达不同空间位置的脑电活动极性及强度，对地形图构型无显著影响。7。

Improvement: the pain reduced by 1 grade, the cervical vertebral physiological curvature restored by 3°- 5° and rheoencephalogram showed that the vertebroarterial blood supply restored to 40％- 80％ of the normal range.

无效：疼痛无变化；颈椎的生理弯曲恢复3°以下；脑血流图椎动脉收缩峰速度在正常范围的40％以下。

METHODS: Eleven specimens of medulloblastoma were acutely dissociated and triturated into single cells without trypsin digestion.

本研究旨在利用简化的无血清培养基和悬浮培养方法，从人髓母细胞瘤中分离培养脑肿瘤干细胞，观察其在体外的增殖、分化。

According to the image manifest of DSA to analyze the size 、distributing、shape、aneurismal neck、having thrombus or not 、crevasse and blood stream conditi...

根据DSA的影像表现对脑动脉瘤的大小、分布、形态、瘤颈、有无血栓、破口及血流情况等进行分析。

MethodsThe external carotid artery of rat was ligated to observe the effect of PAMD on cerebral blood flow、cerebral vascular resistance、blood pressure and heart rate.

方法采用结扎颈外动脉的方法，观察PAMD对大鼠脑血流量、脑血管阻力、血压、心率等的影响。结果PAMD可增加脑血流量，降低脑血管阻力，对心脏功能无明显影响。

Results 371 bp DNA fragment was amplified from 24 different species. The sensitivity could be improved to 10-12 g. No signal was observed when human DNA,funguses and viruses were used as templates. 22 blood samples and 4 cerebrospinal fluid samples, being positive with culture, were positive by using PCR. The gramnegative and grampositive probes hybridized to clinic samples and different species, as predicted by Gram stain characteristics.

结果 对24株不同标准菌株进行PCR扩增，均出现371 bp长度的DNA片段，敏感性试验可检测出10-12 g的细菌DNA，与人类基因组DNA、真菌及病毒无交叉反应；22例血培养阳性标本及4例脑脊液培养阳性标本均扩增出371 bp长度DNA条带，反相杂交法区分革兰阳性/阴性细菌与培养结果相符。

Following intracarotid injection of capsaicin (10μmol, 0.1 ml), the ELI neurons were markedly increased in nucleus paragigantocellularis lateralis, locus coeruleus, area postrema and nucleus tractus solitarius, as compared with the results of vehicle-control rats, while the FLI neurons of raphe nuclei and periaqueductal gray were not affected.

与对照组相比，颈总动脉注射辣椒素(10μmol， 0.1 ml)时，脑干内巨细胞旁外侧核、蓝斑、最后区和孤束核等部位的FLI神经元显著增加，而中脑中央灰质和中缝核群的FLI神经元则无明显改变。

But in the 18 dead cases, there are 13 whose blood fiow velocity of end systolic stage are lower than those of end diastolic stage. Conclusion The blood flow velocity of patients with subtentorial brain injury or metabolic or diffused brain disease have no obvious change.

结果 浅昏迷患者的TCD表现无特征性改变，当出现中度昏迷或深昏迷时，颅内幕上结构损害患者TCD表现与文献报告相似，颅内幕下结构损害、代谢及弥漫性脑病患者大脑中动脉血流速度改变不明显，但死亡的18例病人中有13例出现了收缩期末血流速低于舒张期末血流速。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
