The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.

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.

The results show that the rare earth element Ce can codeposit with cobalt-base alloy, and with increase of mass added of Ce in solution, the content of Co, Ni, Ce in alloy increases and the content of B decreases. Ce can increase plating rate of alloy in some range of content. The rare earth makes deposition potential mve in positive direction and polarizability decrease.

结果表明，在水溶液中稀土元素Ce可以与钴基合金实现共沉积，且随着镀液中Ce的浓度的增大，合金镀层中Ce、Co和Ni的含量逐渐升高，B含量降低；且Ce在一定范围内能够明显提高合金的沉积速度；稀土还使Co-Ni-B合金的析出电位发生了正移，减小了极化度。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.
