Thus it is presented an effective RNA extraction method based on the nuclease adsorbent macaloid, poly vinyl pyrrolidone, and high concentration of KAc and ethylene glycol monobutyl ether, which has successfully extracted high-quality RNA from many materials difficult to RNA isolation, such as RNase-rich rabbit liver, plant and microbial tissues rich in polysaccharides, lipids and polyphenol compounds.

现利用硅藻土对RNase的吸附性，结合PVP、高盐及乙二醇丁醚沉淀等处理，建立了一种广泛适用的RNA提取方法。在富含多糖的玉米胚乳，富含RNase的动物肝脏，多酚多油脂的银杏、麻疯树以及木霉、酵母等10多种RNA提取困难的动、植物与微生物材料中都提取出完整性好，得率高的RNA。

We adopted many forestry techniques, including scarifying, weeding, draining, fertilizing, digging far-between dyke, choosing and breeding eximious clone. We also took measures of excavating aperture and irragating root, directly watering root, daubing remedy, stubbing died trees and sterilizing soil in the aperture.We carried through integrated preventional measures of chemical prevention and biological prevention, by using 200×CuSO4, 70% mancozeb 800×5% Chlorothalonil 800×, and Suillus grevillei. All of the meaures got favorable results. The preventional effect exceeded 72%. The incidence of disease descended from 15.5% in 1998 to 2.8% in 2002.This kind of disease was controlled on the whole.

自1998年开始，经过5年的系统研究，通过松土除草、排水施肥、挖隔离沟，选育优良无性系等林业技术措施；采用挖穴灌根法、直接浇根法、涂药法、死树挖除并对穴内土壤消毒等方法，使用硫酸铜200倍液、70％代森锰锌800倍液、5％百菌清800倍液和厚环乳牛肝菌进行化学防治和生物防治等综合防治技术，均取得了很好的效果，防治效果达72％以上，发病率由1998年的15.5％，下降到2002年的2.8％，使该病基本得到了控制。

Therefore, the calli induced from endosperms can be another source for producing curcin, which is an effective way to solve the problem of poor natural resources, and have the advantages of simplicity, short production period and not limited by geographic area, season or climate conditions.

因此，利用麻疯树胚乳为外植体诱导出的愈伤组织可以作为种子毒蛋白curcin的另一个生产来源，是有效解决自然资源匾乏的途径之一，具有简便、快速、规模化、不受地区、季节与气候限制等优势。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
