Endophytic fungus strain As was isolated from the phloem of the root of Celastrus angulatus.

从新鲜苦皮藤根皮中分离并筛选到1株内生真菌，编号为As菌株，对其代谢产物进行了生物活性研究。

The primary studies on insecticidical and fungicidical components of endophytic fungus in Celastrus angulatus have been carried out from September, 2000 to June, 2002.The results are as follows: Taking PDA and Czapek as separating culture medium, 39 strains of endophytic fungus were separated from the bark, phloem and xylem of the root and twig of Celastrus angulatus.

作者于2000年9月至2002年6月对杀虫植物苦皮藤中内生真菌的杀虫杀菌活性物质进行了初步的研究，取得了以下结果：采用常规的内生真菌分离方法，以马铃薯葡萄糖培养基、Czapek培养基为分离用培养基，从苦皮藤根和侧枝的表皮、韧皮部和木质部中分离得到39株内生真菌。

The best culture medium for root induction of Celastrus angulatus was that containing: 1/2 MS+MET3.0 mg.L-1+IBA 0.8 mg.L-1 or 1/2 MS+ MET3.0 mg.L-1 + IBA 0.5mg.L-1 for 12 days, in dark.

诱导苦皮藤组培苗生根的最佳因素配比为：1/2 MS+MET 3.0 mg.L-1 + IBA 0.8 mg.L-1和1/2 MS +MET 3.0 mg.L-1 + IBA0.5 mg.L-1，暗培养12 d效果最好。

The active compound Celangulin-V, which is the main active compound against insect pest from Celastrus angulatus Max, was modified at its 6-OH and the core structure β-dihydroagarofuran polyol of Celangulins from the basic hydrolysis of the extract of the root bark of Celastrus angulatus Max was modified by combinatorial chemical method.

主要结果如下： 1、合成了苦皮藤素V6-乙酯、6-烯丙基醚和6-酮等衍生物，通过NMR方法鉴定了化合物的结构，经文献检索均为新化合物，生测结果表明酮衍生物丧失了杀虫活性，乙酯衍生物与苦皮藤素V活性相当，醚衍生物较苦皮藤素V活性提高11倍。

The apical bud of Celosia cristata was immersed in 0.05%, 0.1%, 0.15% and 0.2% colchicine solutions for 12 h, 24 h, 36 h, 48 h respectively and the chromosome numbers of the root tip cells in the regenerated plantlets were examined, which showed that the treatment with 0.15% colchicine solution for 36 h would be the best combination that the polyploid rate could reached 23.3%.

采用浸泡法将鸡冠花营养芽在0.05%、0.1%、0.15%和0.2%不同秋水仙溶液浓度下分别处理12h、24h、36h和48h，并对诱导处理后获得的再生植株进行鉴定，得出以0.15%秋水仙素溶液浸泡36h为诱导多倍体的最佳处理组合，诱导率达23.3%。

The extract of cemental matrix can enhance the initial attachment of HGF and HPC on the root surface.

牙骨质基质提取物能够促进牙周膜细胞在牙根表面上的附着。

Results: The extract of cemental matrix could enhance the initial attachment of human gingival fibroblasts and human periodontal cells to the surface of root, and such effects were strengthened with increasing density and time.

且牙骨质基质提取物促牙周膜成纤维细胞附着的作用高于对牙龈成纤维细胞的作用。

RESULTS: During tooth root patterning, expression of MSX1 was found not only in dental papilla of the apical area, dental sac and odontoblasts, but also in dental attachment apparatus such as cementoblast, periodontal supporting tissues and alveolar bone.

结果：在牙根发育不同时期内，MSX1mRNA不仅在牙乳头、牙囊组织及成牙本质细胞中有阳性表达，而且在牙附着组织，如成牙骨质细胞、上皮根鞘、牙周组织及根周牙槽骨组织中也有表达。

Effects of boron on the growth, nutrition quality and nitrogen-fixing ability were studied in Chamaecrista rotundifolia. Compared with the control, the branch numbers, root and shoot biomass of C.

设立田间小区试验，探讨在红壤中施用不同浓度的硼肥对圆叶决明植株生长、牧草品质和根瘤固氮能力的影响。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
