The cytomorphological changes of K562 cells were observed in the electron microscope.Results RRTJ at the concentration of 1μL/mL expressed obviously inhibitory effect on the growth of K562 cells.The inhibitory effect at the concentration of 2μl/ml went up to its highest at 83.4%.RRTJ showed virulence to K562 cells.The karyon changed because of RRTJ attending.

结果 每mL培养液含1μL刺梨汁即对肿瘤细胞增殖有明显的抑制作用，每mL培养液含2μL刺梨汁抑制作用达到最大，为83.4%，再加大剂量抑制作用无明显升高，各种剂量的刺梨汁对细胞均无毒性，刺梨汁的加入使得细胞体积明显变小，细胞核形态发生改变，异染色质增多。

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

本研究选择不同起源地的葡萄品种－－包括西欧品种群的赤霞珠和葡萄园皇后、东方品种群的里扎马特、欧美杂种红双味、美洲种砧木1103Paulsen，以及近年来发展较快的品种群间杂交新品种红地球和皇家秋天等七个品种盆栽苗，在进行不同程度的干旱胁迫处理后，利用气体交换参数和叶绿素荧光参数同步测定的方法，研究干旱对其光抑制程度的影响，以及光呼吸和叶黄素循环组分在其光保护中的作用；并在分别抑制光呼吸和叶黄素循环的基础上，探讨了赤霞珠葡萄两种光保护机制的互补效应；同时选择不同的酿酒葡萄品种赤霞珠、品丽珠、梅鹿辄和砧木1103Paulsen的叶片，研究其离体干旱条件下光抑制程度、光呼吸活性及其光保护作用，结果发现： 1。

The results showed that Lactarius camphorates, which could inhibit HIV-1 PR by 80.9%, was the only sample exhibited over 80% inhibition on PR at 0.5mg/ml.

在已测的22种食用菌多糖复合物对HIV-1 PR的抑制活性实验中，反应浓度为0.5mg／ml下对蛋白酶抑制活性最高的是香乳菇，其抑制率达80.9％。

In addition, the inhibition of flesh leatheriness development of loquat fruit by hypobaric pressure storage was correlated to the reduced POD and PAL activities.

结果表明，减压处理可明显抑制冷藏枇杷果实的呼吸强度、乙烯产生和果实褐变，并保持较高的果实可溶性固形物、可滴定酸度和维生素C含量，抑制贮藏21 d后果实硬度的增加，减轻出汁率的下降，降低POD和PAL酶活性的上升趋势，抑制木质素含量的增加。

The results showed aqueous shoot extracts of Euphorbia maculata could inhibit seed germination speed in all the four species, reduce seed germination rate in Lycopersicon esculentum, Schizonepeta tenuifolia and Capsicum frutescents, and its effects increased with the increase of extracts concentration, while having no effects on seed germination of Edible umaranth.

结果表明，斑地锦浸提液可降低四种蔬菜种子的发芽速率，抑制番茄、辣椒和荆芥的发芽率，并且这种抑制作用随处理浓度的提高而加强，而对苋菜种子的发芽率无显著影响；0.4 g/ml的斑地锦浸提液强烈抑制了四种蔬菜根的生长，却不同程度地促进了辣椒、荆芥和苋菜茎的生长，对根/茎比的影响与对种子发芽率的影响类似。

To sum up, both experiments in vivo and in vitro show that activating blood circulation to dissipate blood stasis has effects of inhibiting proliferation of malignant cell, inducing differentiations and impelling apoptosis. These perhaps were the machinisms of clinical effects. Considering the effects on DNA content, we dares inferred that YDQ inhibited proliferation by restraining the synthesis of DNA. It asks for our doing more work to research the underlying machinism with immunology, cytobiology, molecularbiology and so on.

总之，体内、体外实验均表明活血化瘀为主的疗法对恶性细胞有一定的增殖抑制、分化诱导和凋亡促进作用，这也许正是临床治疗MDS取效的原因所在，分析瘀毒清对细胞DNA含量的影响，我们推测认为瘀毒清可能通过抑制细胞DNA的合成进而抑制恶性细胞的增殖，其更深的机制尚待我们从免疫学、细胞和分子生物学等角度进一步研究揭示。
