Vascular endothelial growth factor (VEGF or VEGF-A) is a hypoxia induced angiogenic growth factor that is potent in neurotrophy, neuroprotection, anti-apoptosis and cell proliferation.

VEGF是一种由缺氧诱导的血管生长相关肽，在脑内有比较丰富的表达。VEGF具有神经营养、神经保护、抗凋亡、细胞增殖、提高毛细血管渗透压等广泛的生物学作用。

Objective To gain stable genetic modification of neural stem cells that constitutively secrete brain-derived neurotropic factor and to explore the biological role on the survival and neurite outgrowth of cultured dorsal root ganglion neurons.

目的 建立稳定表达脑源性神经营养因子基因的神经干细胞并观察其对于体外培养的脊髓背根神经节细胞存活及突起生长的影响。

PR content of the mixed type was higher than that of the hyperplastic t ype; and the PR content of the hyperplastic type was higher than that of the atr ophic type. The relationship between ER and PR contents of the vulvar dystrophy and adjacent normal tissue was in positive correlation. The PR content of vulvar squamous cell carcinoma went down along with the drop of its dedifferentiation degree. The PR content of carcinoma was much lower than that of the adjacent nor mal tissue.

结果：ER的含量混合型高于萎缩型，PR的含量混合型高于增生型，增生型高于萎缩型（ P值均＜0.05）；外阴营养不良及其邻近正常组织的ER与PR的含量之间呈正相关关系（P ＜0 。01），外阴鳞状细胞癌PR的含量随分化程度的降低而逐渐降低，且癌组织PR含量明显低于其邻近的正常组织。

Regulation of follicular development and atresia is a complicated process,including the interaction of endocrine factors,ovarial regulatory factor and nutritional factors during the controlling of the ovocyte fate.

卵泡发育和闭锁的调节是一个复杂的过程，包括内分泌因素、卵巢内调节因子及营养因素在控制卵母细胞的命运中的相互作用。

These results can lead to the following conclusion:〤GRP synthesized by the motoneurons may be a self-serving neurotrophic factor after axotomy.(2) CGRP may serve as a "injury signal" activating both the central and peripherical gli

本研究结果提示，运动神经轴突损伤后，运动神经元合成分泌的CGRP对神经元自身具有直接的神经营养作用，CGRP还可以作为损伤神经元分泌的&损伤信号&激活中枢和外周胶质细胞，从而为运动神经元的存活和轴突再生创造有利的微环境。

The vascular changes interfere with diffusion of nutrients from plasma into adjacent perivascular tissue and cells.

这些血管变化干扰了营养物质从血浆中向血管周围邻接的组织和细胞扩散。

通过营养神经扩血管药物—碟脉灵，主要成分为腺苷和异黄酮，改善耳蜗微循环，促进耳蜗细胞自由基的清除，提高听阈。

CaMK was mainly accumulated in vascular bundle sheath cells of leaves and highly expressed in lateral root primordia and root tips. But the kinase was under detectable in other regions.

在营养器官中钙调素激酶主要分布于叶的维管束鞘细胞、侧根原基和根尖等部位，而其它部位没有检测到明显的分布。

To study furderly the activity of CNTF mutant designed by computer molecular modling,this study used the methods of dissociated cultures of chick dorsal root ganglion、TF-1 prolification and the normal mice′weight loss tests.

为了进一步研究我室应用计算机分子模拟设计并表达纯化的睫状神经营养因子突变体蛋白的生物学活性，分别采用鸡胚背根神经节无血清培养法、TF-1细胞增殖法、正常小鼠减重法对其活性进行研究。
