Methods:Human CD80 cDNA was transfected into B16 melanoma cells by lipofectin-mediated gene transfer before the expansion of tumor cells were tested by MTT method in vitro;C57BL/6 mice were inculated subcutaneously either mock-transfected B16 cells (B16-neo)or CD80-transfected B16 cells (B16-CD80),then the latency,survival times and tumor mass growth were investigated.The lymphocytes were examined for both proliferation indices and specific cytotoxic activity by MTT method and improved LDH-releasing method,after syngenic Mixed Lymphocyte tumor cultures.

通过脂质体介导将CD80基因导入小鼠黑色素瘤B16细胞后，利用SABC法检测CD80的表达；MTT法测定肿瘤细胞体外增殖能力；将肿瘤细胞接种至同源小鼠皮下后观察成瘤期、荷瘤小鼠存活期及肿瘤结节生长速度；在同源淋巴细胞肿瘤细胞混合培养后，通过测定淋巴细胞增殖指数和CTL杀伤活性检测肿瘤细胞的免疫原性。

No tapetal cells were formed or tapetam collapsed at very early stage in some anther chamber during the microsporogenesis; Pollen mother cells in another chamber were not developed and microspore vacuolized; Tapetum cells developed abnormally, giantized and crammed the anther chamber; Some tapetum cells developed normally, but PMCs developed abnomally, which deformed at sporogeneous stage, and then were abhensive each other and finally degenerated. Nearly no PMCs could complete the process of meiosis, and form the tetrad, leading to the failure of normal microspore development.

药室的绒毡层细胞不形成或提前解体；药室内的花粉母细胞不发育或小孢子液泡化；绒毡层细胞发育异常，出现巨型化而挤满整个药室；绒毡层细胞虽发育正常，但花粉母细胞发育异常，在造孢细胞时期即开始出现变形现象，随后发生粘连退化；绝大部分花粉母细胞不能完成正常的减数分裂过程形成四分体，导致小孢子退化。

It is concluded that AD5/F35 vector infection has difinite selectivity to hematologic malignant cells of varions origin,the infection ability of AD5/F35 vector to cells of myeloid origin is stronger than that to cells of B cell origin,the cytotoxicity of AD5/F35 vector to infective targer cells is small.

AD5/F35载体对不同来源的血液恶性细胞的感染具有一定的选择性，对髓系来源细胞感染能力强，对B系来源细胞有一定感染能力，而且对感染靶细胞毒性小。

These results indiacated that tranferring macrophages combinedwith cytokines could be a new adoptive immunotherapy protocol foradvanced cancer,and rTNF used in vivo locally could induce andactivate macrophages to kill tumor cells.Monocytes when activatedunderwent a series of phenotypic and functional changes includingthe expression of IL-2R which may provide an important immunoregu-latory pathway.The presence of lectin-like molecules on thesurface of monocytes and tumor cells may bring theeffector/target cells together,thus facilitating the inductionof apoptosis in target cells by triggering the production ofcytolytic factors and the modification of target of targer cell surface anti-gens.(such as HLA-DR).

综合以上结果可以得出以下结论：转输巨噬细胞并结合细胞因子的联合应用是肿瘤继承性免疫中的又一新的、有潜力的方法；抗肿瘤细胞因子rTNF可通过激活巨噬细胞在体内抑制对其不敏感的肿瘤细胞的生长；人单核细胞在一定条件下激活后，可表达IL-2R，进而一方面增强其自身对IL-2的敏感性，另一方面在体内也具有调节T细胞功能的作用；单核细胞和肿瘤细胞上存在的凝集素类受体可促使两种细胞之间在凝集素介导下相互接近，并诱发单核细胞产生细胞毒因子，以及通过调节靶细胞上表面抗原的表达，促进诱导靶细胞的细胞凋亡。

Results: Cords could be found both in the left and right ventricles. The frequency of the ventricular cords in the left and right ventricles was respectively 88.89% and 85.19%. The false tendon were classified into four types: muscular, conductive, mixing and tendinous. The muscular cords were composed of cardiomyocytes. The conductive cords contained Purkinje cells, T cells and a few P cells. The mixing cords consisted of cardiomyocytes and a few P cells.

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.

我们的研究发现，后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的，PFC中dlg完全缺失型突变引起PFC的分化异常，导致卵子发生中期卵母细胞骨架重组异常，Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化，但是在一定程度上影响伸展细胞和向心细胞的分化，并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。
