两株新分离的APMV-I毒株感染SPF鸡的超微病理变化

将APMV-I鹅源分离株YG97鸡源分离株Y98和NDV强毒株F48E8感染SPF鸡，运用透射电镜观察该2株病毒分离株对机体细胞的影响，结果显示3株禽副黏病毒均引起机体肝、胰、脾、肾、心、胃、十二指肠和直肠等实质器官组织细胞的超微病变，如黏膜上皮细胞多处受损，表面微绒毛脱落；实质细胞核固缩、凝聚、凹陷、核多形性，线粒体嵴断裂、空泡样变、膜溶解，粗面内质网扩张、囊泡变，细胞浆的囊泡内及细胞浆内存在有囊膜的成熟病毒粒子等，但YG97和Y98对不同实质器官的组织细胞超微病变程度不一：胃、肝、胰、脾、肾超微病变比心脏的超微病变严重。电镜观察结果还表明：3株禽副黏病毒引起宿主细胞的超微病变有2种形式：坏死性病变和凋亡性病变。     

The Brief Introduction to the Sino-US Joint Centers for Soil and Water Conservation and Environmental Protection

Erosion and transport of soil has worldwide implications for agriculture, landscape stability, climate, natural hazards, and clean, renewable resources of water and air. Assured access to clean water and a healthy and safe environment requires an ethic of conservation and protection. The minimum scale in which these principles apply successfully is basin wide. These are the fundamental concerns of the Sino-US Centers for Soil and Water Conservation and Environmental Protection.     

槟榔红色素的抗氧化活性

测定槟榔红色素(areca red pigment,AP)对 DPPH·和·OH的清除能力、对脂质体过氧化的抑制能力、对Fe2+的络合能力,并测定其还原能力.结果表明:槟榔色素对DPPH·、·OH的清除能力较强:对脂质体过氧化的抑制能力很强,抑制率高达79.84%;与VE、没食子酸(gallic acid,GA)、BHT相比,槟榔色素的还原力、对Fe2+的络合能力较弱.说明槟榔红色素是较好的抗氧化剂.     

Effect of bFGF on glucose regulated protein 78 expression and apoptosis in human ovarian cancer CAOV3 cells

AIM: To evaluate the effect of bFGF on the apoptosis and the expression of glucose regulated protein 78 (GRP78) in ovarian cancer CAOV3 cells.METHODS: Starvation induced cell apoptosis was conducted. After treatment with bFGF, the cell cycle and apoptosis were determined by FACS analysis and Annexin V/PI staining, respectively. The expression of protein kinase B (PKB) and GRP78 were detected by Western blotting and RT-PCR. RESULTS: Compared to starvation group, the cells treated with bFGF were still viable and increased activation of PKB and high expression of GRP78 were observed, which were prevented by PKB inhibitor wortmannin effectively (P<0.01). CONCLUSION: bFGF plays a critical role in anti-apoptosis and proliferation in human ovarian cancer through PKB signal transduction pathway, partly by upregulating the expression of GRP78.

弘扬茶文化 促进社会主义和谐社会建设

中国是茶的故乡,是世界上茶历史最悠久、茶资源最丰富、茶文化最深厚的国家.茶在中国始终扮演着社会交往的最佳礼物和媒介,是人与人之间友谊的桥梁.茶文化的本质是"和谐文化",它引导人们与自然和谐相处,启示人们在人与人的关系上,要彼此尊重,加强交流,启发人们感悟身心的统一.大力弘扬茶文化精神,是建设和谐文化的一笔重要资源,是构建和谐社会的重要载体.     

不同弱光环境下番茄幼苗生长的变化

对10个基因型不同的番茄品系幼苗进行了不同弱光下株高和茎粗变化的研究。结果表明:一层遮光处理期间各番茄品系株高增加,但在处理的初期和末期增加幅度较大。二层遮光处理初期,株高比对照增加,但随着处理时间的延长,株高逐渐下降。各品系的茎粗则随着遮光程度的加重和遮光时间的延长呈现出比对照逐渐减小的趋势。各品系的株高/茎粗比在一层遮光处理期间和二层遮光处理初期比对照增加,在二层处理中、后期则下降,不同品系变化幅度不同。
