先前的工作发现，眼镜蛇孟加拉种的神经毒分布存在明显的地理差异，但是导致这种现象的原因还不是很清楚。

Were comparativey studied using immunocytochemical tech niques-peroxidase antiperoxidasemethod.These positive immunoreactive systems were compared with the neuroanatomical data on neuropile organization and single nerve cell type in the bee's brain.

通过免疫细胞化学方法－PAP法，研究了中华峰和意大利峰脑和视叶中乙酰胆碱、5－羟色胺（5－HT）、γ－氨基丁酸免疫反应阳性神经元胞体和纤维的形态、染色强度、分布和各种神经丛之间的联系。

Results There were three morphological types of BM metastasis of NB, microinvasive, moderately invasive and diffusely invasive pattern. CgA/NSE immunohistochemical staining was needed fur confirming the metastatic neuroblastic cells in microinvasion.

结果 神经母细胞瘤骨髓转移表现为微小浸润、中度浸润和弥漫浸润三种形式，主要根据骨髓造血组织与肿瘤成分的比例和分布而定，其中微小浸润常需行CgA/NSE免疫组化染色辅助诊断。

Results The uplift of retinal neuroepithelium, separation or abnormal band of retinal pigment epithelial were found in all eyes.

神经上皮脱离腔内有细小尘状反光点36只眼，占39.14%。其中簇状分布17只眼（17.61%），柱状8只眼（8.69%），环形6只眼（6.52%），团块状5只眼（5.43%）。

We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。

Moutains of evidences from laboratary and clinical data show that gene abnormality is the major etiological factor of over 40% patients affected with epilepsy.There were also 6 epilepsy genes been cloned successfully, and mutations of over 1000 genes maybe related to epilepsy. These abnormal genes influence many aspects from molecular level to the neuronal plasticity, such as the development of brain,neuronic degeneration, remodeling of neural circuits, energy metabolism, ion channel and so on.These factors would at last affect the formation of epilepsy focus, propagations of epileptic potentials, vulnerability of epilepsy cells.

大量的实验和临床资料提示基因异常是40%以上癫痫患者的病因，有6种常见全身癫痫的基因已被成功克隆，1000种以上的基因突变可能与癫痫的发作有关，这些表达异常的基因分布在脑发育、神经元变性及神经环路重组、能量代谢、离子通道等多个环节，从分子、细胞、神经元可塑性等多个方面影响着癫痫灶的形成、痫性放电的扩布及癫痫细胞的损伤，构成了癫痫的基因机制。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
