Conclusions］There is a significant difference at protein level between untreated and ethambutol treated mc2155 cells. It suggests that the differential expression analysis of proteomes may be useful for further study on microbiostatic mechanism of ethambutol and search for new targets toward anti-TB drug development.

结论］乙胺丁醇处理前后耻垢分枝杆菌mc2155细胞的蛋白质组具有差异，这种蛋白质组的差异分析有助于进一步研究乙胺丁醇抑制分枝杆菌生长的作用机制并为寻找新的抗结核药物作用靶标奠定基础。

［Objective］To investigate the microbiostatic mechanism of ethambutol, proteomic methods were used to find differential expression proteins in Mycobacterium smegmatis mc2155 cells treated with ethambutol.

［目的］利用蛋白质组学方法，识别乙胺丁醇处理前后耻垢分枝杆菌mc2155细胞后差异表达的蛋白质，为进一步探讨乙胺丁醇抑制分枝杆菌生长的作用机制及寻找新的抗结核药物作用靶标奠定基础。

Based on the result of PSI-BLAST search against GenBank Database, 38 microbial rhodopsin sequences were collected from archaea, eubacteria and eucarya. Two different phylogenetic methods were used to analyze their sequence alignment based on 7 transmembrane a-helice. The result of phylogenetic analysis shows that these microbial rhodopsins were divided into three clades.

对美国基因数据库进行PSI-BLAST搜索后，筛选了38条来自古细菌、细菌和真核生物的视紫红质蛋白质序列并进行了蛋白质结构和序列比对，并对比对结果用了邻接法和贝叶斯法进行了基于7个a螺旋跨膜结构的系统发生分析。

Recombinant wild type PrP purified from E. coli was used to form amyloid fibrils.

Amyloid fibrils formed from different proteins, each associated with a particular disease, contain a common cross-beta spine.

淀粉样原纤维由不同蛋白质（这些蛋白质都与一种特殊的疾病有关）形成，包含常见的β交联核心。

The changes of biochemical properties were studied by extractability and ATPase activity measurement, SDS-PAGE analysis, and ultrastructure observation of fish meat from grass carp treated with different concentration TP and stored at 4℃.

研究方法及结果如下：1、通过测定盐溶性蛋白质的提取性、ATP酶活性、SDS-PAGE凝胶电泳、扫描电镜，分析4℃贮藏条件下的不同浓度TP处理的草鱼鱼肉蛋白质的生化特性的变化。

Chrome in fodders, eggs, livers and lungs of hens that fed by common fodders is tested.

铬革渣主要由65%的蛋白质、%的Cr2O3和中性盐组成，是丰富的蛋白质资源。

Sativa meal and both weight gain rate and relative growth rate also increased significantly. The above indexes of fish fed 4% and 12% M. sativa meal were higher than those of fish fed 16% M. sativa meal and were lower for fish fed fresh M. sativa than that of the control group. 2 With increased levels of M. sativa meal in the diets, crude protein content in the muscle of fish fed M. sativa meal increased significantly, while EE and cholesterol were significantly decreased and moisture showed a quadric curve variation. Fish fed fresh M. sativa had no improvement in comparison to the control group. 3 Protease and amylase in foregut, midgut, hindgut and hepatopancreas of C. carpio increased with increased M. sativa meal but the variation was not linear.

试验Ⅰ、Ⅲ组的上述2项指标高于对照组，试验Ⅳ组低于对照组，苜蓿鲜草组低于对照组，但差异均不显著。2和对照组相比，添加苜蓿草粉显著或极显著提高了禾花鲤肌肉中粗蛋白质含量，随着苜蓿草粉添加水平的增加，肌肉中粗脂肪和胆固醇水平显著下降，肌肉中水分含量呈先降后升的二次变化趋势，苜蓿鲜草组的肌肉中粗蛋白质、粗脂肪含量和胆固醇水平无显著变化。3添加苜蓿草粉后对消化道各部位蛋白酶活性及淀粉酶活性有促进作用，均呈先升后降的变化趋势，其中试验Ⅱ组的酶活性最高。

And the vitro protein digestive ability of each digestive organ is in the sequence of stomach＞ foregut＞pylorus cecum＞midgut＞hindgut. The mean vitro digestive coefficient of feedstuff dry matter is in the sequence of Peru fish meal＞homemade fish meal＞ shrimp meal＞meat meal＞feed yeast＞soybean meal＞earthnut meal＞cottonseed meal＞wheat bran＞middling, and the mean vitro digestive coefficient of feedstuff protein is in the sequence of Peru fish meal＞shrimp meal＞homemade fish meal＞meat meal＞feed yeast＞soybean meal＞earthnut meal＞middling＞cottonseed meal＞wheat bran.

十种饲料原料的干物质体外消化率依次为进口秘鲁鱼粉＞国产鱼粉＞虾粉＞肉粉＞饲料酵母＞豆粕＞花生粕＞棉粕＞麦麸＞次粉，蛋白质体外消化率依次为进口秘鲁鱼粉＞虾粉＞国产鱼粉＞肉粉＞饲料酵母＞豆粕＞花生粕＞次粉＞棉粕＞麦麸，动物性饲料原料的干物质、蛋白质体外消化率明显高于植物性饲料的相应体外消化率。
