利用光学显微镜和扫描电子显微镜观察了6种杜鹃属植物的叶片结构，结果表明，它们具有共同形态结构特征：典型的异面叶，上表皮由2~3层细胞组成，内大外小或内、外等大，有较厚的角质膜，无气孔器分布；下表皮均由1层细胞组成，排列紧密；栅栏组织由2层以上长柱形细胞组成，排列紧密；海绵组织细胞较短，排列较疏松，细胞间隙较大；均有表皮附属物。

It is well-known that for eucaryotic cells, DNA is located in the karyon and can not penetrate to the cytochylema and the tissue fluid because the cell membrane can act as barriers for DNA transportation. Therefore, the appearance of DNA in cell matrix and the serum can indicate that some diseases have taken place. A main reason for cancer occurrence is the mutation of DNA. It may cause the change of the sequence and expression of cancer suppressor genes.

真核细胞的DNA广泛的存在于细胞核内的染色体上，由于核膜的选择性通透作用，使DNA无法分散到其它细胞的亚器官，加之细胞膜的隔离效果，DNA更难扩散到细胞外基质中，因此细胞外基质中DNA含量的增加往往也会预示某些疾病的发生。

Conbining previous results with our results, we conclude that the soluble gp130 mutant containing CBD can antagonize the biological activities of IL-6 by competitively binding IL-6/IL-6Rα with wild-type gp130, and the membraneanchored mutant could transduce IL-6 signal, but its efficiancy was much lower than that of wild-type gp130, therefore, we thought the Ig-like module also played an important role in IL-6 signal transduction by involving in the formation of a hexameric IL-6 receptor complex.

结合以前的研究结果，我们认为只含胞外CBD区的gp130突变体通过与膜结合型gp130竟争结合IL-6／IL-6Rα复合物而具有拮抗IL-6功能的作用；而只含胞外CBD区的gp130突变体，尽管仍能传导IL-6信号，但其效率远低于野生型gp130，因此，我们认为gp130的Ig样区在IL-6转导中也起着十分重要的作用。

When they are released into the extracellular environment, or when they are membrane-bound and in contact with the pericellular zone, these enzymes degrade a broad range of connective tissue proteins and are important during the development of healthy tissue as well as in remodeling damaged tissue.

当它们被释放入细胞外环境，或者是与膜结合后与细胞外环境保持接触时，这些酶能够使大范围面积的结缔组织蛋白酶降级，这样对健康组织的发育以及对受损组织的重塑相当重要。

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.

For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.
