OBJECTIVETo study the content of mineral elements and the principal components in Gastrodia elata.

METHODMineral elements were determined by ICP and the data was analyzed by SPSS.

RESULTK element has the highest content-and the average content was 15.31 g x kg(-1). The average content of N element was 8.99 g x kg(-1), followed by K element. The coefficient of variation of K and N was small, but the Mn was the biggest with 51.39%. The highly significant positive correlation was found among N, P and K . Three principal components were selected by principal components analysis to evaluate the quality of G. elata. P, B, N, K, Cu, Mn, Fe and Mg were the characteristic elements of G. elata.

CONCLUSIONThe content of K and N elements was higher and relatively stable. The variation of Mn content was biggest. The quality of G. elata in Guizhou and Yunnan was better from the perspective of mineral elements.

OBJECTIVETo investigate the effect of ganoderma lucidum polysaccharides on blood lipid and lipoperoxidation from the experimental hyperlipidemic rats.

METHOD50 rats were randomly divided into normal group, hyperlipidemia control group, experimental group 1, 2 and 3 in which the rats were treated with ganoderma lucidum polysaccharides at dosages of 200 mg x kg(-1) and 400 mg x kg(-1) and 800 mg x kg(-1) respectively. Apart from the rats in control group, all the rats in other groups were fed with high fat forage for 30 days. The blood was collected from the tails of rats for measuring the serum TC, TG, HDL-C, LDL-C, GSH-Px, SOD and LPO.

RESULTGanoderma lucidum polysaccharides could significantly decrease the serum contents of TC, TG, LDL-c in the experimental hyperlipidemic rats (P < 0.01), and markedly increase the level of serum HDL-C (P < 0.05), Mean Level of blood LPO in the experimental groups treated by ganoderma lacidum polysaccharides at different dosages were much lower than that in hyper lipidema group, and the GSH-Px and SOD activities of blood in the group of ganoderma were much higher than those in hyperlipidema group.

CONCLUSIONGanoderma can regulate lipid metabolism, enhance the antioxidation and reduce the lipid peroxidation in the rats with hyperlipidemia.

The strain of DG7 isolated from the oilwater sample in DAGANG oilfield could produce surfactant ?acids and gas in the culture medium in which the diesel was sole carbon source .The strain was Gram-negative, motive, rod and growed facultatively in the 0 to 18.5% NaCl. Based on its characters, the strain was identified as a member of the genus Aeromonas, but there were some differences between this strain and the described species of this genus in some biochemical features, suggesting that it could be a new species of the genus.

HBeAg is an ungranular secretory protein,which encoded by C gene of HBV DNA and it increases with the replication of HBV. So it is one of the markers of active replication of HBV in clinical diagnosis. HBeAg is important biologic raw materials which is widely used in preparation of related diagnostic articles with HBV infection serological detection. The technology of expression and purification of recombinant HBeAg is quite mature,which had successfully expressed the target protein in various expression systems. The key factors on HBeAg expression include important site mutation in precore region ,the choice of vectors,effects of RNA interference(RNAi)and so on. Therefore,in order to meet requirements of related diagnostic products,it need to improve expression level and purity of recombinant HBeAg and avoid cross-reaction with HBcAg. In a word,it showed that acquisition of high quality recombinant HBeAg could lay substantial foundation for improving diagnostic products,provide a reliable evidence for exploiting new type of therapeutic and preventive HBV vaccine and offer possibility of HBeAb detection methodological optimization.
