This project studied the mechanism of a newfound phytotoxin from Alternaria alternata Keissler that infects Crofton weed. According with the result from experiment, the project group drew a conclusion that the toxin did not inhibit respiration in mitochondrion, so the key problem was whether the toxin inhibited photosynthesis in chloroplast.

As results, TEM showed characteristic ultrastructure morphology of apoptosis cell with chromatin marginal condense, nucleus pycnosis, mitochondrion vacuoles and cell shrinkage in IR injury group and no apoptosis cells in control group. Increased TUNEL-positive cell and typical DNA laddering were found and cells apoptotic rate were approximately 20% by flow cytometry assay in experimental groups.

值得探讨。本试验通过流式细胞仪、生物电镜、TUNEL法、RT-PCR以及DNA电泳等试验方法研究了带血供同种异体骨移植过程的细胞凋亡现象，并检测了Fas、FasL、Caspase-1、Caspase-3、Bcl-2等凋亡相关基因在IR损伤时的表达及变化情况，初步探讨了骨移植时IR损伤中细胞凋亡的发生机制及其在IR损伤中的生物学意义，希望为今后更深入的研究打下一定基础。

实验Ⅱ组肾小球毛细血管可见内皮细胞孔，局部轻度增生呈连拱状，系膜细胞少量核不规则或轻度固缩状，胞质内线粒体轻度肿胀，部分嵴断裂。

Results:Sorbaria sorbifolia extract significantly increased the activity of SOD in brain tissue, decreased the content MDA, inhibit the MAO activity. It was observed under microscope that Sorbaria sorbifolia could retrieve the degeneration of mitochondrion.

结果：珍珠梅提取物可提高D半乳糖所致大鼠脑组织SOD活性、降低MDA含量，抑制MAO活性；电子显微镜观察到珍珠梅提取物可以减轻D半乳糖导致的线粒体等超微结构的改变。

This suggested that AIF and Endo G translocate from mitochondrion to nucleus in OGD/R.

说明OGD/R过程中AIF和EndoG可能由线粒体转位到核。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.

对过氧化物酶的细胞定位研究发现，无论抗病杨树还是感病杨树，接种后均发现细胞中有过氧化物酶反应产物，通过分析发现，毛白杨过氧化物酶的活性不仅明显高于未接种的对照，也明显高于接种处理后的北京杨，并且定位更广泛，在细胞壁、细胞间隙、叶绿体膜、线粒体膜及液泡膜上均有大量定位，而北京杨酶反应产物主要分布于细胞壁上，在细胞膜、核膜局部有少量定位，定位范围及强度均小于毛白杨。

The size of follicle begin primordial follicle to tertiary follicle(1.5～3mm).The number of mitochondrion increased,and the cristae increased.Gogi body change to type,cortical granule increased,and moved behind cytolemma.The proportion of small,middle and large follicles on ovary were 92.51%(92.51±5.87),4.60%(4.60±4.91) and 2.88%(2.88±2.22) respectively.

卵泡在发育过程中，卵泡细胞形成的突起与卵母细胞始终保持密切的联系：卵母细胞从原始卵泡到直径1.5～3mm的三级卵泡，细胞质中线粒体数量由少到多，线粒体内的嵴不断增加，高尔基体由不典型到变成典型，皮质颗粒由开始形成到形成较多的皮质颗粒，并逐渐地迁移到卵母细胞膜下。

In this paper, the stable Au complexes are classified according to the coordination atoms and their characteristic structure. The recent development of the researches on the antitumor activity of Au complexes including the structure-activity relationship, biological targets and the mechanisms of action are reviewed. The structure of the coordination ligand and the leaving group have great impact on the in vitro cytotoxicity of the Au complex. Many physical and biological methods are introduced to study the interaction between the Au complexes and the suspected bio-target, such as DNA, protein, mitochondrion, thio-containing biomolecules, etc. The interaction modes (intercalating, electrostatic interaction, covalent bonding, etc.) are focused to illustrate the reason for the antitumor activity of Au complexes.
