Methods The logarithmically growing CEM cells cultured in vitro ( cell density 2 × 105/mL) were exposed to 0.1, 0.5, 1, 5, and 10 μM Dex, then were collected 24, 48 and 72 hrs later. Untreated CEM cells were used as Controls. The cell viability was determined by trypan blue dye exclusion.

方法将在体外培养的对数生长期的CEM细胞浓度调至2×105个/mL，接种于24孔培养板中，用终浓度分别为0.1，0.5，1，5，10 μM地塞米松处理，以不加任何药物的CEM细胞作为对照组，培养后24，48，72 h取样。

The colour of most detected bands became light in the five media with the order of mannosan, mannose, xylan, glucose and pectin.(4)The pectinase in the supernatant was purified by centrifuge , acetone precipitation and sephadex G-75 cloumngel filtration. The specific activity was increased 9.8-fold with an activity recovery of 32.98%.The molecular weight of pectinase was 42.2KD estimated by SDS-PAGE.

确立了以葡萄糖培养基6h的发酵液为提取果胶酶的最初取样点，发酵液经离心，丙酮沉淀，Sephadex G-75葡聚糖凝胶柱层析后获得了凝胶电泳均一的样品，比活力较原酶液提高了9.8倍，回收率达到了32.98%，用SDS-PAGE凝胶电泳测的纯化后的果胶酶分子量为42.2KD。

The results also suggested that both sampling effect and niche complementarity effect may operate mechanistically in the diversity effect, and this show that the species with particular traits, such as higher productivity and competitive ability, and the species with resource partitioning are likely to have large impacts on ecosystem functioning.

分析结果还表明，在多样性-生态系统功能关系中，取样效应和生态位互补效应共同发生作用，说明物种的特性及物种在资源利用方面表现出的异质性对生态系统功能可能都有重要影响。
