马传贫驴白细胞弱毒疫苗株跨膜蛋白主要免疫决定区基因的克隆与表达

从感染驴白细胞的马传贫驴白细胞弱毒疫苗株前病毒DNA中克隆了编码跨膜蛋白主要免疫决定区(TMIR)的基因，并在大肠杆菌中进行了表达。所表达的融合蛋白有一部分是可溶的，其氨基端带有6个组氨酸的标签，因此可以用固定化金属离子亲和层析法在非变性条件下进行纯化。在间接酶联免疫吸附试验(ELISA)和免疫印迹试验中，重组的TMIR蛋白可与马传贫阳性血清样品发生反应，而与健康马血清无任何反应。这表明该重组蛋白具有良好的抗原性和特异性，可用于马传贫弱毒疫苗株在体内外复制、接种马体内免疫应答及马传贫诊断的研究。     

羔羊全营养代乳粉对羔羊增重影响的试验

为了研究羔羊出生后采取人工饲喂代乳粉溶液的效果，对10日龄羔羊称重，以平均日增重与母乳组比较，用t检验方法检验差异显著性。研究结果显示羔羊平均日增重试验组为0.097-0.126kg，母乳组为0.071-0.113kg，二者没有显著差异。在生产中，代乳粉能替代绵羊母乳饲喂羔羊，对多胎品系羊的推广应用以及解决绵羊缺乳、少乳或无乳问题具有重要意义。     

从矿难报道看转型期媒体的社会功能——以《南方周末》的矿难报道为例

处于社会转型期的中国，媒体有其特殊性：多元化的社会转型需要媒体发挥较为多元化的社会功能。一方面要继续保持党和政府的喉舌功能，另一方面叉要通过舆论监督来建立媒介信任，从而达到建立社会公信力，抢占市场的目的。笔者以《南方周末》的矿难事故报道为对象，分析目前中国媒体所担负的具体社会功能。

Validation of the accuracy of household reporting of subsistence fishing catch and effort: a Fijian case study

Abstract  The accuracy of household reporting of subsistence fishing catch and effort and seafood consumption on the Fijian island of Ono-i-Lau was studied. A creel survey was carried out concurrently to validate the household survey data. Reported estimates of fishing participation, effort, and fish consumption were not significantly different to the creel survey estimates. Householder's appeared to overestimate the number of fish from the most abundant family Lethrinidae, and underestimate rarer fish. However, there was no significant difference between the reported and observed contribution of the majority of finfish families and invertebrate taxa. The reported and observed catch rate estimates were not significantly different, indicating that Ono-i-Lau villagers are relatively accurate in their estimation of the number and size of fish from recalled catches.

Growth of triploid oyster, Crassostrea madrasensis (Preston)

The performance of I and II meiotic triploids and control oysters (Crassostrea madrasensis) reared at Tuticorin Bay was compared to determine if the improvements in the growth of edible oysters were additive to faster growth in triploids. After a grow‐out period of 12 months, both mean whole weights and shell heights were in order I meiotic triploid>II meiotic triploid>control. Mean whole weights and shell height of different oyster lines were all significantly different (P<0.05). On an average, larger morphological traits indicated that growth improvements from triploids were additive, and throughout the study triploid oysters maintained faster growth rate than their diploid siblings. Condition index and adductor muscle diameter of both triploids were higher than those of control.
