The botanical characteristics and biological characteristics of DeHong Elephant grass and King grass were observed and compared.

通过对德宏象草和王草的植物学特征、生物学特性进行观测比较，结果表明：德宏象草种子实生苗生长速度快，其自然扩展蔓延途径主要依靠种子繁殖进行；德宏象草的干物质产量、主要营养成分均极显著高于王草P。

Results Stable drug-resistant SW1990/GZ cell strain was established by culturing with gemcitabine for 9 months. The morphology and growth characteristics of the cell strain changed remarkably. The cells shrinked and became rounder; its endoplasm expanded; granular substances increased; and the doubling-time was prolonged. Resistance of the cell line to gemcitabine, fluorouracil, adriamycin, and mitomycin significantly increased. The TrxR activity of the drug-resistant cells was increased markedly.

结果 药物培养9个月后，得到稳定传代的SW1990/GZ耐药细胞株；其形态学、生长特征等均发生了明显变化，细胞变圆、体积缩小、内质网扩张、颗粒样物质增多及细胞倍增时间延长；对吉西他滨、5-氟尿嘧啶、阿霉素和丝裂霉素的耐药性均显著增加；耐药细胞的TrxR活性也明显增高。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。
