In the rice leaves infected by RDV Yunnan isolate, the distribution of cells full of virus particles formed a belt which was a center of infection and multiplication of virus, around the cells fall of virus particles were some cells with the different extent of lesion as follows: disappearance of membrane system of chloroplasts, there were virus particles in some chloroplasts, and some sine or assembled virions in the mitochodria or cytoplasma but not in nuclei ,and intact subcellular structure in the cell far away from the infected center; In the rice leaves cell infected by Zhejiang isolate, some cells were full of virions, but the distribution of cells didn't form the belt, other cytopathological characters were similar to the cells infected by Yunnan isolate.

RDV云南分离株浸染的水稻叶片中，充满病毒粒体的细胞呈条带状分布，呈现出明显的侵染和增殖中心，在充满病毒粒体的细胞周围，相邻细胞有不同程度的病变，叶绿体膜系统消失，部分叶绿体中含有病毒颖粒，线粒体残体及细胞质中有分散或聚集的病毒粒体，细胞核中未见病毒粒体，离侵染中心较远的细胞中亚细胞结构较完整；RDV浙江分离株侵染的水稻叶片中，部分细胞充满病毒粒体，无明显的条带状分布，其他细胞病理特征与RDV云南分离株侵染的水稻叶片相似。

In group 35mg/kg, the karyopyknosis of the tubular epithelial cells of cortical increased. The structure of epithelium disappeared, that of glomcrulus disorganized and medulla were involved. In group 25 mg/kg and 30 mg/kg, severity of pathological changes were between that of group 20 mg/kg and group 35 mg/kg.

35mg/kg染毒组皮质部小管上皮细胞细胞核固缩增多，上皮细胞结构消失，少数肾小球结构紊乱，髓质部小管细胞核固缩，管腔消失。25mg/kg和30mg/kg染毒组病理损伤程度介于上述两组之间。

Grass leaf with Kranz anatomy --- C4 plant 有花环结构的禾草 Two bundle sheathsOuter one is parenchymatous; inner is a mestome sheath ??

用C4植物来表示。其维管束鞘只有1层细胞，有花环形结构，是高效光合作用植物，如玉米、高梁、甘蔗以及桑科的一些种类。C4植物能把叶肉细胞中所放出的CO2能被再次利用。

Furthermore, flow cytometry showed that the number of cells in G1 phase increased and the number of cells in S phase decreased, the number of cells in G2/M phases relatively increased. The changes of subcell structure could be seen, such as cavernous cells, cytoplasm agglutination, increasing apoptosis.

结果：0、10、20和40mgL^(-1)，姜黄素对Hela细胞增殖的抑制率分别为3.0%、21.4%、32.8%和49.2%，且呈剂量依赖性；流式细胞术显示，G1期细胞增多，S期细胞减少，G2/M期细胞相对增多；细胞结构显示，细胞空化、染色质凝集、凋亡小体增多。

Results Curcuma （0,10,20 and 40 mg·L-1）had obvious inhibitory effects on the Hela cell proliferation in a dose-dependant manner,the inhibitory rates were 3.0%,21.4%,32.8% and 49.2%,respectively. Furthermore, flow cytometry showed that the number of cells in G1 phase increased and the number of cells in S phase decreased, the number of cells in G2／M phases relatively increased. The changes of subcell structure could be seen, such as cavernous cells, cytoplasm agglutination, increasing apoptosis.

结果：0、10、20和40 mg·L-1姜黄素对Hela细胞增殖的抑制率分别为3.0%、21.4%、32.8%和49.2%，且呈剂量依赖性；流式细胞术显示，G1期细胞增多，S期细胞减少，G 2／M期细胞相对增多；细胞结构显示，细胞空化、染色质凝集、凋亡小体增多。

Different cells,cell density and cell shape lead to comparatively great difference in wood properties and physical mechanical properties, change of wood cells affects change of wood properties including wood quality,wood property and all other aspects,and wood properties decide economic value and directly affect manufacturing and utilization of wood,therefore,the research and analysis on wood cell structure become especially important.

由于树木生长不均匀，使各种树木的木材构造具有多样性，不同细胞体、细胞密度和细胞形状导致了木材材性和物理力学性能存在较大差异，木材细胞的变化影响着木材性质的变化，木材的性质又决定木材经济价值，并直接影响木材的加工和利用，由此对木材细胞结构分析研究就变得尤为重要。

Based on setting up mathematical model of wood fiber cell structure, this paper studied on the variation description method of wood fiber cell structure, at the same time, this item set up the judging rule of the smallest cutting thickness of micrometer wood fiber cell splitting, gaining the high strength MFB of poplar whose modulus reach above 5171MPa.
