Methods RG21 was extracted from Radix Gentianae by hot water extraction, dichloromethane extract and centrifugalization. The CPE inhibition assay was used to test the antiviral activity of RG21 on RSV in Hela cells while ribavirin was used as a positive control.

长期以来，由于RSV的免疫及病理基础等研究还不完全清楚，临床上并无安全、有效的抗RSV感染的药物及疫苗，因此，开发研制有效防治RSV感染的新药已成为近年来国际医药学界研究的热点。

Now, Flavonoids and ginkgolides were mainly extracted from the leaves of Ginkgo biloba., but the leaves often contain high content of corious and cereous, and the effective constituent is very different under the various conditions. In addition, the constituent of ginkgolides is very low in the leaves, and thus the quality of extraction is difficult to reach the international standards.

目前人们主要从银杏叶中提取银杏黄酮和萜内酯，但由于银杏黄酮和银杏内酯的含量很低，尤其银杏叶中最主要的有效成分银杏内酯B主要存在于根中，在银杏叶中含量极低(＜0.1％)，且是在生长状态的叶中含量最高，采叶影响树的生长；又因银杏叶中主要的有效成分受多种因素的影响又有很大差别，银杏叶革质化、蜡质化程度高，使得国内银杏叶提取物的质量很难达到国际标准。

We developed the spatial information, which included DTM, topography, slope, aspect, altitude, temperature, precipitation, light soil types, soil texture, administrative zoning, forestry zoing, stream transportation network. The colored aerophotos were scanned and corrected to be orthogonal images. Then, land cover were interpretated and land-use mapping. Ecological site quality of Chamaecyparis formosensis were evaluated for productivity. Habitat suitability index of warbers and guid were evaluated for biodiversity of landscape. The restoration strategies of collapsed area after Chi-Chi earthquake were developed by land evaluation.

本研究以中兴大学实验惠荪场为，进空间资讯之建构，其内容包括DTM、地形、坡、坡向、海拔高、气温、雨、湿、光、土壤种、土壤质地、政区划、业区划、溪、交通线等分布，并用彩色航空摄影照片扫描化且校正成正射投影之影像、地覆判释、郁闭、分高分布图与土地用型图制作；由空间资库进分层取样设计，以供有效之地面调查，而进生产的生态地位评估、地景多样性的野生动物栖息地适宜评估、以及集集921 地震后崩塌地分析、评估与回策之拟定应用，结果显示空间资讯在生态系经营的政策性与策性规划应用上，相当有效。

The available component can fast penetrate into interior of skin , and it removes the aging skin , recruit nutrient element , especially be good to protect skin from dryness , desquamation , and chapping etc.

通过透皮吸收，有效成份快速渗入肌肤内层，有效去除死皮，补充养分，尤其针对皮肤干燥、脱皮、皲裂、干涩等症状，理疗效果明显。

ResultsThe AB-8 resin was founded to be suitable for separation and purification of chromone glycoside.

大孔树脂吸附分离技术可有效富集中药活性部位，是提高中药制剂水平的一种有效方法［2～4］。

objective to investigate law of development of chrysomyia megacephala in natural condition,and to probe its application in forensic medicine.methods rate of development and total effective temperature of chrysomyia megacephala were observed,recording the result and statistical analysis.results two equation of linear regression（y1=0.430 8+0.237 1x,y2=75.684 6-1.444 7x） were established between the total effective temperature and the length or weight of chrysomyia megacephala.conclusion it can be used to estimate the time of death in forensic medicine practice depending on the mathematical model from the effective temperature.

目的 研究大头金蝇在自然条件下的发育规律，探讨其在法医学中的应用。方法对大头金蝇在自然条件下的发育速度及有效积温进行观察、记录和统计学处理。结果确立了y1=0.430 8+0.237 1x，y2=75.684 6-1.444 7x 2个有效积温与蛆长和蛹体质量的线性回归方程。结论在自然条件下用积温法建立起的大头金蝇发育数学模型可应用在法医学死亡时间推断中。

After the classific mapping, this dissertation uses the Standard Deviation and maximum Value of the comgfort pencentege that different passive methods could reach within 12 months to define the real capacity of each passive methods.

此外本文还利用各被动式设计策略在一年中12个月的有效时间值的标准方差和最大值结合的办法来判断各项策略的实际有效程度。

It is an efficient measure to prevent patients from AAD for using antibiotics reasonably and utilizing the gastrointestinal tract actively.Patients with AAD should be isolated and used antibiotics for the lower-induced-AAD as possible as we can,clysis with feces solution of healthy person is good for curing AAD.

结论合理使用抗生素，积极使用胃肠道途径是预防SICU患者发生AAD的有力措施；发生AAD后，应采取有效的隔离措施，尽可能改用诱发AAD率低的抗生素，正常人大便混悬液保留灌肠是治疗AAD的有效方法。

Vascular hyperpermeability is one of the important causein hypovole-mia and organs disfunction after various kinds of shock,and its treatment is still one of the problems in the medical field. For example,the operative methods of preventing hyperpermeability and plasm bleeding is still unreliable after severity burn,and traditional treatment just passively transfuses according to the burn clysis formula instead of inhibiting permeability by injecting drugs. The principal reason is that pathogenesis of vascular endothelial cell permeabilty has not been entirely revealed at the level of molecular biology.

血管通透性增高是休克时有效血容量减少和器官功能损害的重要原因之一，它的防治一直是医学界的一个难题，如在大面积烧伤时，至今未能找到一个简单有效的防治血管通透性升高和血浆渗出丢失的方法，传统的方法只是根据烧伤补液公式测算进行被动的补液来纠正，而不能依靠注射化学制剂来终止其渗出，主要原因是未能从分子生物学水平揭示血管内皮细胞渗出的机制。

Colostrum Microfiltrate is supported by a number of process patents that cover the production of concentrated colostral wheyfractions using minimal heat. This process uses microfiltration instead of pasteurization, which can destroy beneficial components.

初乳精华Colostrum Microfiltrate 拥有许多专利制程，能以最低温度，有效保护浓缩的初乳，这项制程以专利低温萃取技术取代传统的巴斯德杀菌法，而能有效保护初乳中的有益成分不受破坏。

The split between the two groups can hardly be papered over.
