The fatty acids and waxes of Myrica rubra kernel were analyzed through GC-MS, The results showed that the yield of kernel oil was 31.10%, and there were eight fatty acids and three long-chain alkanes in the extracted composition. The main composition were Palmitic acid 28.22%, Linoleic acid 14.4%, Oleic acid 25.74%, Erucic acid 15.68%, Heptadecane 5.2%, Octadecane 5.87%, Nonadecane 4.71%. The total content of unsaturated fatty acid was 55.91% with the Linoleic acid and Oleic acid of 40.19%, these supplied a reference to its comprehensive utilization.

Eleven subcloned DNA fragments from the 5′- upstream region of lipA, lipC and lipF of Phanerochaete chrysosporium were assayed by using the gel mobility shift assay. The total proteins extracted from P.chrysosporium mycelia grown in Kirk medium and natural fir wood chip were used to identify the segments in these 11 DNA fragments which are controlled by some regulatory proteins.

Results The metamorphotic cells were de creased in 9-cisRA group. THP-1 cell adhesion rate was inhibited by 50%(P.01), and the cell surface markers (CD11b, CD36) were decreased by 50% and 28%(P.01) in 9-cisRk treated group.

结果 9-顺式维甲酸干预后梭形、分支状细胞明显减少，与佛波酯单独作用组相比细胞贴壁率减少50%(P.01)，细胞表面标志物CD11b和CD36分别减少50%和28%(P.01)。

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.

BmNPV hr3已被证明具有增强子功能，将hr3与hel510启动子顺式连接的质粒pBmhel510luc-hr3down转染Sf-21、Bm-N和Hi-5细胞后，再用上述三种病毒分别感染每一种细胞，hel510启动子的转录活性得到显著提高，表明病毒因子能够识别hr3，二者通过相互作用，共同增强解旋酶基因启动子的转录水平。

The possibility of 1,4-asymmetric induction in some nucleophilic addition reactions of chiralγ-amino Z-enals 7 with organolithium compounds was investigated.
