在野外池塘中，利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响，结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应，在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上；根、茎、叶和石芽各构件都具有异速生长现象，并且表现规律不一样；菹草的根冠比随底质营养盐的不同而变化；随着营养条件对菹草生长胁迫加重，根、冠的异速生长愈明显，同时石芽的N∶P和C∶N比率显著受底质营养盐的影响，而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响，这些响应将改变石芽第2年的命运和影响种群的维持；在胁迫生境下，菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续，以回避策略应对底质营养盐胁迫。

生长激素是鱼体正常生长、发育必不可少的内分泌激素，外源生长激素的补偿可以加速鱼体生长，生长激素通过注射、浸泡、投喂作用于鱼体，显著促进了鱼体的生长，提高了饵料的转化效率。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.

结果表明，尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件，但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖，采用丙酮法进行细菌培养液多糖提取，发现细菌培养的第3天所提多糖含量最高；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖，且在细菌培养的第4天所提多糖含量最高；胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率，这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。

Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells. They were observed to inhibit hepatoma cells.

Maternal hypertension, low pre-pregnancy weight, and primiparae were the risk factors for both symmetric and asymmetric SGA infants. Those effects except primiparae were considerably greater on asymmetric than symmetric SGA infants. Low parental height and previous LBW or PTD history were also significantly associated with the risk of symmetric SGA infants.
