this study evaluated the different expressions of cherry tomato growth, yield and quality under bamboo and rice husk biochar applications to soil. The experiment was conducted under glasshouse conditions at Hakozaki campus, Kyushu University, Japan and consisted of 5 treatments, namely 1) no biochar application as a control;2) 2% (RH2) and 3) 5% (RH5) of rice husk biochar;4) 2% (BB2) and 5) 5% (BB5) of bamboo biochar. Bamboo biochar application significantly improved tomato growth, including number of leaves, fresh biomass yield of aboveground and underground parts for BB5;number of fruit;fresh yield from 24% - 25% for BB2 and BB5. In particular, both bamboo and rice husk biochar application at two rates 2% and 5% had positive effects on tomato quality, demonstrated by the increased total sugar content from 56% to 91%, and the enhancement of ascorbic acid content for BB2 and RH2 by 12% and 17%, respectively. Those improvements reflected the soil physiochemical property changes after biochar application, including the increase in plant available water for bamboo biochar amendment before and after cultivating by 25% - 38% and 9% - 18%, respectively, compared with those of control;and the increased total soil N for bamboo biochar treatments (11% - 14%). Generally, all data above support bamboo biochar utilization for the purpose of improving soil properties and developing crop production.

河流重金属污染由于其具有的潜在危害性而受到广泛的关注,重金属含量则常被用作判别河流水环境质量的重要指标。红河是越南第二大河流,但目前对红河沉积物的重金属污染研究仍很薄弱。论文以越南境内红河上游(老街)至河口、水下三角洲采集的50个表层沉积物为对象,对其进行了粒度、重金属、常量元素地球化学组成和磁性特征的表征,旨在评价重金属污染及其空间变化,分析其影响因素,并探讨磁性特征指示沉积物重金属污染的可行性及其内在关联机制。主要结论如下：1、自红河上游至三角洲平原地区,沉积物粒度呈现先变粗后变细的特征。水下三角洲中,水深5m以浅区域中沉积物以砂质组分占主导,而水深5 m以深区域则主要为粉砂和黏土主导。沉积物粒度特征变化反映了不同沉积环境的水动力强弱。2、根据聚类分析与主成分分析等结果,红河流域沉积物中重金属(Cr、 V、Cu、Cd、Pb、Ni和Zn)可分为两组。其中Cr、V与黏土、Al、Fe、Mn和有机碳(TOC)含量高度相关,表明这些重金属主要富集在富含Fe/Mn氧化物黏土矿物以及有机碳的细颗粒沉积物主要来自自然地风化过程。Cr和V从上游到河口地区逐渐增加,特别是自F39采样点(F39为三角洲河流分汉之处)向河口地区增加趋势尤为明显,反映了粒度对其含量的控制作用,这些因素主要来自自然的风化过程。而Cu、Cd、Pb、Ni和Zn与粒度的关系较弱,其含量自上游向下游无明显变化趋势,这些元素含量在红河上游局部地区呈现高值,说明存在人为污染的影响。3、根据富集因子(EF)计算结果,发现红河沉积物自上游至下游均存在一定程度的重金属污染,其中上游地区污染程度较高。红河沉积物中Cd、Cu和Pb是最主要的重金属污染元素,达到了中度和高度污染水平。4、红河沉积物磁化率x和饱和等温剩磁SIRM有相似的变化趋势,表明红河沉积物的磁性特征为亚铁磁性矿物所主导。磁铁矿和赤铁矿是主要的磁性矿物。粒度是影响沉积物磁性特征的重要因素。χfd%、χARM、χARM/χ、χARM/SIRM与<4μm(黏土)粒级含量之间呈显著正相关;S-ratio与黏土含量呈负相关,表明细晶粒磁铁矿(SP/SD)以及赤铁矿在黏土中富集。自红河上游至河口以及水下三角洲地区,随着黏土含量的增加,磁性颗粒变细,体现了沉积物磁性特征对粒度以及水动力变化的响应。磁性参数χfd%、χARM、χARM/χ、χARM/SIRM可以作为黏土含量的代用指标。5、红河沉积物中未发现磁化率x与重金属含量之间存在明显相关性,这可能指示了磁性矿物与重金属具有不同的来源。磁性参数xfd%与重金属Cr、V、Ni、Zn具有显著的相关性,尤其与Cr和V具有较强的相关性,但与Cu与Cd不具有明显相关性。Cr和V主要来自于自然风化过程,其含量受到粒度特征的控制。由于细粒级组分中较高含量的黏土矿物和铁氧化物对重金属元素具有较强的吸附能力,从而导致了xfd%与Cr、V含量的强相关性。相反,Cu与Cd主要来自于人类活动的污染物质排放,其含量受到粒度的控制作用相对较小,从而导致其与xfd%不具有相关性。Ni、Zn和Pb的含量受到自然风化过程和人类污染活动的双重影响,其与xfd%的相关性程度低于Cr和V,但高于Cu与Cd。因此,在红河沉积物中可将xfd%作为黏土含量的指示指标,并可应用于重金属含量的粒度校正。

Today satellite system provides a main instrument supplying regular data on land inventory and monitoring of land use/land cover changes, in a timely manner. These data are keys to many applications in different sectors: environment, forestry, hydrology, irrigation, agriculture, geology, resource management and planning. Using Landsat image and change detection, this paper presents a method to extract changes of agricultural land, as the basis for the assessment and development of irrigation systems, which enhance production and protect land resources. During the period 1996-2014, the agricultural land in Binh thuan decreased from 43.5% (in 1996) to 40.1% (February, 2014) of the total land surface in the province. However, the land area under cultivation tends to decrease rapidly, from 25.7% in 1996 to 14.0% in 2014. Combining the results of land use change and assessing the capacity of the irrigation systems show which areas are frequently irrigated versus those are not. this allows proposing irrigation development needs contributing to more production while protecting land resources.

Eight strains of nervous necrosis virus （NNV） isolated in Vietnam were used to detect the pathogenicity and immune response in sea bass （SB）. All strains induced cytopathic effect in SB cell line, complete destruction of monolayer of cells appeared after seven days post infection （dpi）. Virus titer was different for each strain, TCIDso ranged from 102.7 to 1069, and LDs0 from 1015 to 1075. Five NNV strains named QN 02, QN 05, QN 07, ND 11 and KH 05 had higher virulence than the other three, the first causing 100% mortality in experimental fish 3-5 dpi. NNV KH 05 had the highest antigenic similarity, and it was inactivated completely by 0.2% formalin, 0.002 mol/L binary ethylenimine （BEI） and 0.1% beta-propiolactone. The neutralization antibody titer obtained in fish of groups immunized by BEI 0.002 M and beta-propiolactone 0.1% inactivated virus was four to eight times higher than that of the group treated with the formalin inactivated virus. The antibody titer in fish immunized with beta-propiolactone inactivated virus was more persistent. The efficacy of vaccines developed from beta-propiolactone inactivated virus and aluminium hydroxide （AH） or aluminum phosphate （AP） was observed by intramuscularly immunizing Epinephelusfuscoguttatus size 1.5 cm. Neutralizing antibodies appeared in vaccinated fish on 10th day post-immunization （dpi） at a dilution of 1：16; 1：32 and highest levels were reached on 30-45 dpi, at dilutions of 1：256 and 1：512, after treatment with AH and AP vaccine, respectively. The relative percent of survival （RPS） of vaccine at 30 dpi was highest with challenge doses 0.2-1 × 10^6.8 TCIDs0, the RPS varied from 80%-83.3% in both groups of AH and AP immunization. this result provides the basis for developing a vaccine against NNA disease.

Objective: To investigated the protective potential of ethanol extracts of Scutellaria baicalensis(S. baicalensis) against lipopolysaccharide(LPS)-induced liver injury. Methods: Dried roots of S. baicalensis were extracted with ethanol and concentrated to yield a dry residue. Mice were administered 200 mg/kg of the ethanol extracts orally once daily for one week. Animals were subsequently administered a single dose of LPS(5 mg/kg of body weight, intraperitoneal injection). Both protein and m RNA levels of cytokines, such as tumor necrosis factor alpha, interleukin-1β, and interleukin-6 in liver tissues were evaluated by ELISA assay and quantitative PCR. C yclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB protein levels in liver tissues were analyzed by western blotting. Results: Liver injury induced by LPS signifi cantly increased necrosis factor alpha, interleukin-1β, interleukin-6, cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB in liver tissues. Treatment with ethanol extracts of S. baicalensis prevented all of these observed changes associated with LPS-induced injury in liver ***: Our study showed that S. baicalensis is potentially protective against LPS-induced liver injury in mice.

The bacterial pathogen Helicobacter pylori (H. pylori) colonizes in over half of the world’s population. H. pylori that establishes life-long infection in the stomach is definitely associated with gastro-duodenal diseases and a wide variety of non-gastrointestinal tract conditions such as immune thrombocytopenia. Triple therapy which consists of a proton pump inhibitor and combinations of two antibiotics (amoxicillin, clarithromycin or amoxicillin, metronidazol) is commonly used for H. pylori eradication. Recently, the occurrence of drug-resistant H. pylori and the adverse effect of antibiotics have severely weakened eradication therapy. Generally antibiotics induce the disturbance of human gastrointestinal microflora. Furthermore, there are inappropriate cases of triple therapy such as allergy to antibiotics, severe complications (liver and/or kidney dysfunction), the aged and people who reject the triple therapy. These prompt us to seek alterative agents instead of antibiotics and to develop more effective and safe therapy with these agents. The combination of these agents actually may result in lower a dose of antibiotics. There are many reports world-wide that non-antibiotic substances from natural products potentially have an anti-H. pylori agent. We briefly review the constituents derived from nature that fight against H. pylori in the literature with our studies.

土地利用总体规划是在一定区域内,根据国家社会经济可持续发展的要求和当地自然、经济、社会条件,对土地的开发、利用、治理、保护在空间上、时间上所作的总体安排和布局。近几年来,越南较快的经济增长速度已经向土地资源及水资源施压、从而引起了重新调整符合于经济快速发展的土地利用规划的需求。同时、气候变化也成为越南发展过程当中的一个新挑战。这些挑战主要包括影响到生活的挑战、生计、自然资源和社会结构等挑战。越南被视为承受气候变化和海平面上升最大影响的两个国家之一。“越南应对气候变化国家目标”的具体目标之一是在经济社会发展计划及全国各地各部门规划战略里集成了气候变化因素;加入世界贸易组织(wTO)也需要对符合于发展水平的土地利用规划及符合于全球化趋势的土地利用规划近性重新调整。因此我们需要扩大土地利用规划的作用范围、包括环境因素、气候变化、经济社会。同时也要为承受土地使用改革的影响的人或集体参加规划过程创造便利条件。这样,将以前不灵活和偏于描述的规划方法转为偏于分析和具有战略性的规划方法已成为土地利用规划过程当中的急需方法。越南土地利用规划的建设在土地法及有关法律文件都有规定。土地利用规划的任务就是划分土地以满足经济、社会发展及环保的要求;同时确保合理、节省、有效地使用土地。目前越南土地管理的法律法规指出、每个土地规划方案都要考虑到与经济、社会及环境相关的关系,同时也要支持各级基层的直接承受影响的对象对每个规划方案积极提出意见。然而在越南,这样的实际参考性的例子还不多,对省级和区级关于实际应用上如何展开的引导还缺乏。中国人多地少、耕地资源缺乏、水土流失、土地退化等生态环境问题日趋严重。走中国特色农业现代化道路全面建设小康社会、随着经济社会的快速发展、对土地的需求量日益矿大、土地供需之间的矛盾也随之加剧。面对人地矛盾十分尖锐的基本国情、必须对有限的土地资源精打细算、严格控制建设用地供应总量、坚决遏制盲目投资和低水平重复建设等行为。为实现土地资源的可特续利用和经济社会可特续发展、必须节约与集约利用土地资源、实行更为严格的耕地保护制度。2005年中国开展好规划实施评价、基础调查、资料搜集和课题研究等规划修编前期工作、为规划修编打下良好基础。2010年、各级土地利用规划编制主要工作基本完成。这些因素和背景条件为发展带来了机遇、必将加强土地规划理论、方法和技术手段研究、借鉴国内外土地利用先进经验和方式、促进土地利用规划学科发展。本课题选取“中国与越南县级土地利用规划体系对比研究”,从加强合作交流,借鉴国内外土地利用先进经验的目的。论文研究的目的： 1、针对目前越南和中国土地利用规划体系对比研究,初步结构分明,功能清晰的土地利用规划体系,分析研究县级土地利用规划的任务和内容。 2、针对目前土地利用规划的目标单一问题,深刻分析土地利用目标的内涵,揭示土地利用规划目标的实质,提出越南和中国县级土地利用规划预期目标。 3、根据规划目标和规划内容的层次性,中国与越南县级规划的控制指标体系对比研究。 4、拟对中国与越南县级土地利用规划的内容和方法进行初步探讨。

湿地植物根表铁膜对包括重金属在内的物质迁移转化具有重要作用,其氧化铁组成研究备受重视,但利用环境磁学方法进行表征的研究还未见报道.本文对长江口潮滩植物芦苇根系及周边沉积物进行了磁学分析,并结合沉积物粒度、漫反射光谱等测试,对芦苇根表铁膜的磁性矿物组成进行了系统研究.结果表明,芦苇根表铁膜磁性矿物主要包括磁铁矿和赤铁矿.由于沉积物不同深度氧化还原环境的不同,铁膜磁性矿物组成存在垂向差异.研究柱样24 cm深度以上,由于相对氧化的环境,铁膜磁性矿物除磁铁矿外,还有较多的赤铁矿贡献;24 cm深度以下,因根系处于相对还原的环境,磁性矿物以磁铁矿为主.与沉积物相比,24 cm以上深度铁膜中亚铁磁性矿物含量较低,24 cm深度以下则相反,反映铁膜和沉积物磁性矿物来源不同.本项研究表明,磁性测量方法有助于认识湿地植物根表铁膜的矿物组成,对湿地生物地球化学过程研究具有重要价值.

Background: During the nutrition transition period which began in the early 1990s in Vietnam, dietary intake had been changed significantly because of changes in lifestyle and living standard. Objectives: this paper aims to describe the trend for food expenditure and the frequency of meat consumption in households in Ba Vi district, Hanoi, Vietnam from 1999 to 2013. Methods: this is a longitudinal study conducted in Ba Vi district, Hanoi. Semi-annual, face-to face interviews were conducted by well-trained interviewers with 11,922 households to collect data of the household’s income, spending for food and meat consumption. Chi-square test for trend was performed to evaluate the changes of food expenditure over the years. P-value under 0.05 was considered statistically significant. Results: There were ten times increase in household’s mean income and five times increase in mean food expenditure from 1999 to 2013. The percentage of household food expenditure per total family expenditure was really high (55% in 2013). The percentage of rice expenditure per total food expenditure decreased dramatically from 59.9% in 1999 to 33.1% in 2013 while spending for other animal-based, high-protein food was an upward trend, particularly meat (10.7% in 1999 to 24.2% in 2013). The percentage of rice expenditure in well-off households was lower than poor households (55% vs. 61.8% in 1999 and 31.4% vs. 36.5% in 2013). However, the percentage of spending for meat in well-off households were much higher than that of poor households (>10%). Conclusion: Our finding indicated that mean income and food expenditure, particularly meat intake, of households had increased dramatically from 1999 to 2013. The increase of meat intake requires reallocation and direction of Vietnam public health funding and strategy.
