Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

The progress of the cell cycle of Spodoptera frgiperda IPLB-Sf21-AE clonal isolate 9 (Sf9) cells was directed by Flow cytometry analysis.The results showed that the whole time of the cell cycle was about 18 hours and the gapes between every two phases were about 6 hours.At 12-18 hours post AcNPV infection,Sf9 cells were arrested in G\-2/M phase.When the cells in G\-1/S phase synchronized by druge were infected by AcNPV,2/3 of the cells was in G\-2/M phase and 1/3 of the cells in S phase.

Objective The origin and the nature of the Hodgkin and Reed-Sternberg cell of Hodgkins lymphoma has been attracting a lot of medical researchers engaged in studying it,for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells.Great improvement has been made since a new method of isolation of single H/RS cells from a frozen section had been set up by KUppers in 1994,and many studies have approved of the B-cell derivation of H/RS cell.lt has been reported that H/R-S cells might partly be originated from B-cell in our research before,but at the same time,we also found that only 18.8% of H/RS cells express CD20,31.3% of immunoglobulin heavy chain rearrangement have been revealed.

目的 霍奇金淋巴瘤(Hodgkins lymphoma，HL)由于它的恶性肿瘤细胞—H／RS细胞一般只占肿瘤组织的极少部分(不到1％)，且散在分布在背景细胞间，因此对于H／RS细胞的来源和性质研究一直是人们探索的目标。1994年德国科隆大学Kūppers等发展了一种从冰冻组织切片上用显微操作仪挑取单个H／RS细胞的显微切割方法进行H／RS细胞基因分析后，人们对H／RS细胞来源的研究有了突破性的进展，多数支持B细胞来源。

The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色：(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞；(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞；(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性，仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长；具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。

The results indicated that the content of cytosolic CaM in cells treated with exogenous Ca2+ has increased indistinctively, while fluorescence intensity in cells treated with TFP decreased. So we believed that exogenous Ca2+ has little effect on the expression of CaM. High concentration of TFP can enter yeast cells and combine to CaM to make it inactive, which is the reason that TFP restrain the growth of yeast cells. 5mmol/L EGTA could completely arrest the cell proliferation of MFP7 after 28h, when the fluorescence intensity in cells wasobviously increased with flow cytometry and LSCM.

被较高浓度TFP处理过的MFP7胞内荧光强度则相对较弱，推测是因为TFP进入胞内与CaM结合从而使其失活，这也是高浓度TFP抑制酵母细胞增殖的原因。5mmol／L EGTA处理28h左右后，酵母细胞的生长被抑制在G1晚期，此时通过细胞流式法和在激光扫描共聚焦显微镜下观察到胞内荧光强度显著高于对照，说明CaM的表达水平在G1后期开始上升；回加10mmol／L Ca~(2+)处理24h后，细胞开始恢复生长，细胞流式法测定胞内荧光强度有所下降，表明多数细胞完成G1／S转换，进入生长对数期。

Rat glioma cell C6 was infected by the deficiency recombinant retrovirus (named C6TK). The sensitivity of C6TK cells to GCV or ACV increased 450 or 10 times than that of C6 cells respectively. Rat C6 glioma model was successfully built, and SD rats inoculated intracerebrally C6TK cells had normal gliomas. The average survival periods of the rats were about 15 days. However, after treated with ACV, the growth of C6TK tumors obviously regressed, and the survival periods extended to 57.8±8.1 days, especially in rats injected with mixed PA317TK and C6 cells or in situ PA317TK cells, which the tumors nearly disappeared after ACV administration and the survival periods extended to over 120 or 71.4±36.1 days respectively, P＜0.001.

RESULTS: The microscopic observation showed chondrocytes in the transducted group proliferated stably, and triangle, and spindle cells were predominant in the seventh passage, accompanied by few long-spindle and root cells. In addition, the cells were of clear appearance and large lucency. However, in the non-transducted group, long-spindle cells were observed in the fourth passage, and almost all cells exhibited long-spindle shape in the fifth passage.
