ABSTRACT Aim and Methods: Using fast cyclic voltammetry and carbon fibre mi croelectrode, we monitored dopamine release from caudate putamen ,nucleus accumbens and central amygdaloid nucleus of normal rats in v ivo, in order to find out the suitable parameters to evoke DA release of certa in area. DA release was evoked by electrical stimulation of medial forebrain bundl e or ventral tegmental area.

Results: 1 The analysis revealed that GAP-43 immunopositive neurons in rats were localized in all the layers of lateral geniculate nucleus and the layers II -VI of visual cortex area 17,and GAP-43 is stained by a ring and dot figure and brown-yellow colour in cytomembrane ; 2, In the critical period, gene expression concentration and number of GAP-43 immunopositive neurons, in both the lateral geniculate nucleus and the visual cortex area 17, received from the deprived eyes, are reduced.

结果：1、GAP-43在正常大鼠视觉系统表达主要见于外侧膝状体全层和视皮质17区Ⅱ—Ⅵ层神经元胞膜中，呈环状或点状棕黄色免疫阳性反应；2、在敏感期内剥夺眼对侧外侧膝状体和视皮质17区GAP-43表达的免疫阳性神经元染色变淡(P＜0.05)，且免疫阳性神经元数目减少(P＜0.05)。

Some exudation and bleedings happen in the pulmonary alveoli, some inflammatory cells infiltrate into lung tissues; in the serum AMY, ALP, TNF-α, IL-6 increases obviously high, COX-2 expression increase; The expression of NF-κB in big rat lung of SAP increase, and the nucleus is thick dyed, it explain that the NF-κ moved into the nucleus; Stimulate the inflamatory reaction.

我们的实验中见到SAP组的大鼠肺脏组织细胞腔扩大、肺泡壁断裂，有的出现肺大泡，肺泡内伴有渗出及少量非出血，肺组织可见咽细胞浸润；血清中AMY、ALP、TNF-α、IL-6明显增高；在SAP组大鼠肝细胞、肾小管上皮细胞、肺脏小气管及肺泡上皮上COX-2表达增加；NF-κB在SAP大鼠肺脏中表达增加，并且出现核浓染，说明NF-κB前移入核；启动炎症反应等一系列反应SAP大鼠受损伤的肺组织中AQP-1无论在mRNA水平上、蛋白水平上还是免疫组化染色病理学检测上都明显下降。

The classical mechanism of E2 involves estrogen binding to receptors in the nucleus, after which the receptors dimerize and bind to specific response elements known as estrogen response elements located in the promoters of target genes. However, ERs can also regulate gene expression through protein-protein interactions with other DNA-binding transcription factors in the nucleus, or through regulation with production and activity of other genes.

除了与经典的雌激素反应元件结合引起基因转录外，也可通过蛋白质-蛋白质之间的相互作用而调节其他转录因子的转录激活作用，或者对其他转录因子生成或活性的影响而调节基因转录。

Based on thermodynamic relations, the initial values of the quark gluon system from relativistic nucleus nucleus collisions are obtained.

从热力学关系，得到来自相对论核碰撞形成的夸克胶子系统的初始值。

In high energy heavy ion collisions, the suppression of the yield of final state high transverse momentum hadrons is considered to be a important signal of exiting Quark-Gluon Plasma. In the process of Nucleus-Nucleus collisions, hard scattering is on the initial stage.

这种相变的发生是由于以相对论速度飞行的高能重离子在相互发生碰撞的过程中，巨大的粒子动能被沉积在核-核碰撞的有限区域内，并转化为热能，形成极端高温高密环境，迫使强子体系解禁闭，形成QGP新物质形态，并最终转化为末态粒子的产生。
