But recent survey reported that Panicum maximum, a perennial grass in the family of Poaceae and listed as one of the twenty most noxious invasive plants in Taiwan has replaced the role of M sinensis in those areas. As a result of recurrent burning, A. confuse forest has been gradually replaced by the grassland of P. maximum. In this study, I compared morphological, photosynthetic, growth and life history characters of field growing P.

早期的研究指出：在大肚山与铁砧山区的本地植物芒草为当地相思树林反覆火烧后的最优势种；但近年来同一地区的研究显示：大黍已取代芒草的角色，而且发现大黍在火烧后植群覆盖度显著的增加，但芒草却没有相同的现象；反覆火烧使得大肚山地区的相思树林逐渐转变成以大黍为主的草生地。

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

Objective:To study the relationship of morphological changes of kidney and renal parenchyma thickness and clinical significances in the cases with essential hypertension.

Recently It has been found that both recombinant human growth hormone and Glutamine are closely related to the growth and metabolism of the small intestine. So it is our purpose in this research that through studying the morphological and molecular changes, we will understand the effect and the underling mechanism of rhGH and Gln on the adaptation of the remnant small intestine in the parenterally fed, SBS rats, and we will find whether there is an interaction between these two agents and whether they could improve the efficacy of PN synergistically.

目前已发现人重组生长激素及谷氨酰胺均与小肠的生长代谢密切相关，本研究即是通过PN时联用rhGH及Gln，从形态学改变及小肠粘膜上皮细胞分子水平变化上探讨短肠大鼠残留小肠对辅助添加剂治疗的反应，从而评价联用rhGH及Gln对残留小肠代偿的作用及作用机制，了解二药联用的协同治疗效果，为临床治疗提供理论依据。

According to BLAST results in GenBank, molecular phylogenetic tree (Paup 4.0), and the morphological, physiological and biochemical characters, the strain was preliminarily identified as a Streptomyces.

在GenBank中进行BLAST 相似性分析，利用Paup 4.0 构建系统发育树，并结合形态特征、培养特征及生理生化特征，确定此菌可以划分为链霉菌属，且与嗜热淀粉酶链霉菌S。

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明：优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动，而对于碱基替代情况来讲，优茧蜂亚科各个成员间序列变异位点上颠换大于转换；不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群，而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群；在优茧蜂亚科内部，悬茧蜂族Meterorini和食甲茧蜂族Microctonini（排除猎户茧蜂属Orionis）为单系群，而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群；悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持，同时食甲茧蜂族Microctonini被判定为相对进化的类群。
