The report expresses serious concern over the estimated national undernourishment rate of 42 percent, with undernourishment rates in hill and mountain areas as high as 50 percent. Stunting rates in children are estimated to be as high as 60 percent in the Mid- and Far-Western Regions, and acute malnutrition rates of children at nearly 18 percent in the Terai.

报道对全国4营养不良人口达42%的评估表示出了极大的关注，尤其是那些位于山区的居民，营养不良人口比例达到了50%，评估显示60%的儿童发育不良，其中在Terai有18%的儿童严重的营养不良。

The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.

基本营养物质的初步筛选试验证明：大米粉、豆饼粉、麦麸、酵母粉和CaCO3及KH2PO4是发酵培养基中最佳的营养物质，可满足抗菌物质产生对碳、氮和矿物质的营养需求。B-903的发酵过程可分为两个阶段：在30℃下，24小时内，细菌数量达最大值，pH值由低向高变化，但此阶段检测不出抗菌物质的活性；第二阶段，培养41小时后，抗菌物质活性开始显露，至112小时后达最大值，pH值也逐渐由高变低。

In this study the natural growth of milkvetch, Caragana, Amorpha fruticosa, ride a Long, flower sticks and alfalfa, collected in September, the nutritional content of each were measured, the nutritional content of each species compared with alfalfa, and then determine The five kinds of integrated plant nutrition.

本研究选用自然生长的沙打旺、柠条、紫穗槐、踏朗、花棒和苜蓿，在9月份采集，分别测定各自的营养成分，将每种植物的营养成分与苜蓿比较，进而确定上述5种植物的综合营养价值。

This paper analyzed the nutrient content of Andrias davidianus, including protein, fat, calcium and phosphorus; compared the nutrient content of 17 amino acids in protein and the main trace elements in muscle of Andrias davidianus with other high-quality aquatic products (fish, shellfish, shrimp, turtle class, frogs, and snakes); and concluded that Andrias davidianus is a new kind of aquaculture with high nutritional value and significant economic benefits.

张红星1，王启军1，赵虎3，张驰2（1陕西省动物研究所，西安，710032；2 汉中天成生物工程有限公司陕西汉中，723200；3河北农业大学动物科技学院，河北保定 071001）摘要：本文分析了大鲵常规营养成分(蛋白质、脂肪、水分、灰分、钙和磷)的含量，同时对其蛋白质的17种氨基酸和肌肉中的主要微量元素铁、铜、锰、锌进行了与其它优质水产品：鱼类，贝类，虾类，龟、鳖类，蛙、蛇类的营养成分的比较，表明大鲵是一种营养价值极高的经济效益显著的水产养殖新品系。

In this trial, which began in March 2006, researchers injected a dystrophin gene compound called Biostrophin, which was developed with MDA support at Asklepios Biopharmaceutical in Chapel Hill, N.C., into the biceps muscles of boys with DMD.Biostrophin is a combination of miniaturized dystrophin genes and adeno-associated viral shells that home to muscle fibers.

这次试验始于2006年3月，研究人员将名为biostrophin的抗肌营养不良蛋白基因化合物（在俄亥俄州哥伦比亚儿童医院同肌肉营养失调协会的支持下，由Asklepios生物医药公司制造）注入了到DMD男孩们的二头肌中。biostrophin是由微型肌营养不良蛋白基因和来自肌纤维的腺相关病毒壳合成的。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

Canavalia ensiformis protein has relatively high nutritional value,but the unprocessed Canavalia ensiformis protein contains a number of anti nutritional factors such as hemagglutinin ,trypsin inhibitors that limit its used as human food and animal feed.

洋刀豆蛋白是一种具有较高营养价值的植物蛋白质，但是其中含有的一些抗营养因子，如血球凝集素(ConcanavalinA ，简称ConA)、胰蛋白酶抑制剂等，限制了它在人类食用植物蛋白和动物饲料中的应用，其中ConA是最主要的抗营养因子。
