The purpose of this study was to investigate the effect of different doses o f dietary fiber of Tremella fuciformis Berk on lipid metabolism and inte stinal physiology in rats fed diets containing 1% cholesterol and 0.2% cholica cid. Forty-two male Wistar rats were randomly divided into six groups in a 2× 3 factorial design and were fed diets containing different doses (0%、5% or 10 %) of dietary fiber of TFB, with and without antibiotics 0.7g/100g of Nebaci tin (bacitracin: neomycin sulfate = 2:1,w/w) for 4 weeks. The parameters analyz ed included liver and serum lipid concentration , serum and caecal content of short chain fatty acids ,fecal neutral steroids and total bile acids content.T he results showed that rats fed the diet with antibiotics had lower levels ofs hort chain fatty acids in serum and caecal content than rats fed diet withouta ntibiotics.

Various mole ratios of acrylonitrile and methyl methacrylate were used to copolymerize in aqueous solution by Redox and the copolymers were obtained. The copolymers containing MOCT were synthesized by adding MOCT before copolymerization. The copolymer were derived from the copolymerization of AN and MMA in 30L kettle and then were mixed with various contents of MOCT, the copolymer films were cast by solution of the copolymer containing MOCT.

Accordingly, a new plasmid Cm1301 was constructed containing osGP fragment (-197～-56) from the osRACD promoter with the minimal promoter,-90 region of CaMV 35S which confers Gus activity detectably only in roots. In the transgenic plants containing Cm1301, GUS activity was detected mostly in the anther.

由于35S基本启动子是一个根特异表达的启动子，因此将包含osDP5区段的osGP片段（-197～-56）与35S基本启动子连接，构成植物表达载体Cm-1301并转化烟草，研究发现，osGP区段使gus基因在雄蕊中表达水平显著提高。

From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.
