Objective To study the morphological and functional effect of pinealectomy on CRH neurons in paraventricular nucleus of rat hypothalamus as well as thefunction of melatonin supplementation, enrich the research of the effect of pinealbody and melatonin on hypothalamic-pituitary-adrenal axis,provide theoreticalevidence of the effect of pineal body and melatonin on immune function andimmune-associated disease such as tumor and autoimmune disease.

目的： 研究松果体及其褪黑素对大鼠下丘脑室旁核CRH 神经元形态和功能的影响以及补充褪黑素的作用，丰富松果体及褪黑素对下丘脑——垂体——肾上腺轴影响的形态及功能方面的研究，为进一步揭示松果体及褪黑素对免疫功能以及免疫相关性疾病如肿瘤、自身免疫性疾病等的影响机制提供理论依据。

It is generally believed that Venus originated with the typical fast and direct rotation. But in the late evolution process, as a result of atmospheric tides and core-mantle friction inside the planet, the rotation is changed gradually. While some others considered that the change of Venus'rotation perhaps due to the early giant planetesimal's collisions.

一般认为，金星原来具有典型的快速正转的状态，在后来的演化过程中，由于潮汐作用或行星内部流体核与幔间的摩擦作用，使得自转逐渐发生变化；也有研究认为可能是早期受到大星子的偶然碰撞所致。

The plastid transformation of plant has become an alternative to genetic engineering besides nuclear genome.

植物质体转化开辟了除核基因组之外的另一条遗传转化途径，10几年来取得了很大的进展。

The results from the digestion by restriction enzymes showed that there were less EcoR I sites in genomic DNA than in that of Bombyx mori nuclear polyhedrosis virus. It suggested that there might be a different viral replication mechanism in ApNPV life cycle.

结果表明，在ApNPV基因组中只含少量的EcoR I位点，与家蚕核型多角体病毒差别很大，并提示这两种病毒的复制机制可能不同。

The density of [3H]citalopram-labeled 5-HT transporters was determined in forebrain regions and in midbrain raphe nuclei of prepubescent and adult male offspring.

在青春期前和成年期的雄性后代大鼠的前脑和中脑缝核区域检测〔H3〕西酞普兰标记的5-羟色胺转运体。

The immatured and dividing erythrocyte were found. The small lymphocytes with pseudopod and large lymphocytes with the villus were observed also. In addition, the monocyte, neutrophil and thrombu cells were recognized by different shapes of nucleolus.

实验还观察到处于分裂状态的红细胞、细胞表面有伪足样胞突的小淋巴细胞和细胞表面有许多微绒毛突起的大淋巴细胞、核呈多种形态的单核细胞和中性粒细胞及不同形态的血栓细胞等。

However, the cell wall cultured at high concentration of Cu2+(10～200 mg/L) was clearly thickened and became multiple layers, and the pigment decreased and the pyrenoid became one or disappeared. Low concentration of Cu2+(0.01 mg/L, 0.1 mg/L) did not affect the growth of Chlorococcum sp., but the growth became slow and even negative beyond the concentration of 0.1 mg/L.

与对照BG11培养的绿球藻比较，0.01～1 mg/L Cu2+浓度下培养的绿球藻，细胞壁无明显增厚，色素没有多大变化，但蛋白核由一个变为多个；而在高浓度(10～200 mg/L Cu2+)下，细胞壁明显增厚为多层，色素减少，蛋白核减少并回复到1个或消失。

The kernel quantification theory IV provides an effective theoretical tool for processing large-scale sampling data in geosciences.

核数量化理论IV模型为大样本地学观测数据的分析处理提供了一种新的理论工具。

It is already known that the fine fly ash produced when coal is burned contains concentrated levels of uranium and a new report published by Russia's leading nuclear research institution warns of an increased radiation hazard to people living near coal-fired thermal power stations .

人们已经知道，煤炭燃烧时产生的"飞灰"中含有高浓度的铀；同时俄罗斯最顶尖的核研究机构的一项新报告指出，燃煤热电厂对附近居民的辐射威胁越来越大。

However, 5-HT transporter density in the dorsal and median raphe was unaltered in this same group of offspring.

但是，同一组大鼠的背侧和内侧核的5-羟色胺转运体密度没有改变。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
