In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.

本研究采用高效液相色谱-质谱联用法测定了三种棘豆植物的苦马豆素含量；通过ISSR分子标记技术对三种棘豆种群遗传多样性及其苦马豆素相关标记进行了研究；将小花棘豆植物单株进行体外真菌培养，研究了菌落和分生孢子的微生物形态学特性，从植物总DNA和相同植株培养的真菌总DNA扩增真菌的5.8SrDNA/ITS区，进行了DNA序列分析与排序；联系单株小花棘豆的苦马豆素含量测定和内生真菌ITS序列分析结果，与从美国分布的二种棘豆(O.lambertii、O.sericea)和一种黄芪(A.mollisimus)中分离的内生真菌埃里砖格孢属Embellisia sp.L12株得到的结果进行了比较。

This phenomenon can be explain or supposed from two aspects: First, endophyte induced the activities of CAT to increase under drought stress, and the activities of CAT increased inhibited the activities of POD: Second. endophyte or its metabolite inhibited the activities of POD.

这种反常现象可从以下两个方面解释或假设，即：内生真菌在干旱胁迫诱导了CAT酶活性的上升，而上升的CAT酶活性又抑制了POD酶的活性；或者是内生真菌的存在或其代谢产物抑制了POD酶的活性。

To investigate the fluorescence dynamic change of protoporphyrin IX in bladder carcinoma cell induced by 5-ALA and the influence of 5-ALA concentration and pH on fluorescence of PpIX. 2. To discuss the biodistribution and express of PpIX in bladder wall of different lesions by method of instilling of 5-ALA into bladder cavity. 3. To discuss the clinical value of the fluorescence diagnosis in early detection of bladder cancer and the radicality of bladder tumor resection under fluorescence cystoscopy.

本研究目的：1了解5-ALA诱导膀胱癌细胞内生原卟啉IX荧光随时间的动力学变化及5-ALA的浓度、pH值对产生PpIX荧光的影响。2通过膀胱灌注5-ALA探讨其所诱导内生PpIX荧光在膀胱上皮中分布及不同病变表达上的差异。3探讨5-ALA诱导荧光膀胱镜检对发现早期膀胱癌的临床应用价值及在荧光膀胱镜下膀胱肿瘤电切治疗的彻底性。

Among them, strains of Bacillaceae occupied the predominance with 59.1% in various wheat organs. Oxytetracycline resistant strains of Bacillus licheniformis were isolated from wheat rhizosphere, root and stem indicating their high abilities of spreading. Opportunistic human pathogenic bacterial strains with oxytetracycline resistance such as Bacillus cereus and Stenotrophomonas sp. were also isolated from various wheat organs. No oxytetracycline resistant bacterium could be detected from wheat seeds.

土霉素抗性的Bacillus licheniformis在小麦根际土壤、根、茎等器官中都分离得到表明该抗性菌种在小麦内生系统中具有较高的传播性；具有土霉素抗性的人类机会致病菌Bacillus cereus和Stenotrophomonas属的细菌在小麦的根际土壤、根以及叶子中也均分离到，但是在小麦种子中没有分离到任何土霉素抗性的内生菌。

In Chapter five, we discuss the endogenetic institutional evolution explanation of Chinese economic transformation with analysis of such a mode.

第五章中，通过内生演进机制下的中国经济转型模式的研究，我们讨论了中国经济转型的内生制度演进解释，说明了渐进式改革的内在合理性，并探讨了渐进式改革策略与休克疗法之间的差异。

In Chapter five, we discuss the endogenetic institutional evolution explanation of Chinese economic transformation with analysis of such a mode. We argue that there is reasonable reason of the regular reform. At the same time, we discuss the difference of the regular reform and the radical reform.

第五章中，通过内生演进机制下的中国经济转型模式的研究，我们讨论了中国经济转型的内生制度演进解释，说明了渐进式改革的内在合理性，并探讨了渐进式改革策略与休克疗法之间的差异。

The theoretical innovation is that endogenous uncertaintytheory is first introduced to explain the abnormal volatility of Chinese stock markethence making the analysis of abnormal volatility more reasonable. The econometricalinnovation is that state space model is introduced to improve the classical test modelmaking the econometric test more practical and more convictive.

在中国股市异常波动性成因的理论分析中，首次将内生不确定性作为其中的一个重要因素，使得对中国股市异常波动成因的分析更为合理；在内生不确性的实证研究中，根据股市的实际情况，引入状态空间模型，对经典的检验模型进行改进，使得实证检验结果更具说服力。

Endophytes remain relatively unstudied by scientists, however their potential value was illustrated more than a decade ago when the blockbuster cancer drug taxol was isolated from a fungal endophyte collected from a Pacific Yew tree.

内生真菌保持相对自发的科学家，但他们的潜在价值体现在十多年前当畅销的抗癌药物紫杉醇的分离内生真菌收集到太平洋紫杉。

Diversity of endophytic fungi in leaves of Ginkgo biloba was studied in order to understand diversity state and succession change of endophytic fungal communities in this endemic plant. Healthy leaf samples were collected from five main planting locations of G. biloba in Jiangsu and Shandong provinces separately in spring, summer and autumn.

为了解我国特有植物银杏的叶部组织中内生真菌菌群的多样性和演替变化，分别于春、夏、秋季从江苏和山东两省的五个主要银杏栽培地采集健康叶片进行了内生真菌的研究。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
