Based on these results and inferred to related reports from other labratories, it was possible to make some analyses and conclusions or inferrences:(1) CD〓AK with tumoricidal activity were induced and expanded in number througth costimulation of PBMC with anti-CD〓 McAb . and r IL-2 ;(2) CD〓AK induced and expanded in such manner did exibit more potent proliferation·ability and cytotoxicity which maintained for lonser time than those of LAK cells, thus CD〓AK was a new variety of antitumor effector cells worth to be explored;(3) CD〓AK could mediate MHC nonrestricted cytotoxicity and kill tumor target cells through inducing necrosis and apoptosis;(4) Normal mature lymphocytes of PBMC could be induced to proliferate and /or to die from apoptosis when they were costimulated by anti-CD〓McAb and rIL-2. Both proliferation and apoptosis were existing in the same cultivation system sugsesting that the presence of rIL- 2 might provide some accessary signals for apoptosis.

以这些结果为基础并参考其它有关文献可能做出如下分析与结论或推论：(1)用抗CD〓单抗和rIL-2共刺激外周血单个核细胞能诱生扩增出具有杀瘤活性的CD〓AK细胞，(2)与LAK相比，用这种方法诱生扩增的CD〓AK增殖能力强、细胞毒活性强而且维持时间长；CD〓AK是一类值得开发的抗瘤效应细胞；(3)CD〓AK能够介导MHC非限制性细胞毒活性，可以通过诱导靶细胞坏死和/或凋亡杀伤肿瘤细胞；(4)正常外周血单个核细胞中的成熟淋巴细胞在受到抗CD〓单抗和rIL-2共同刺激后既可诱导增殖也可诱导凋亡，两者并存于同一体系，推测rIL-2的存在可能为细胞凋亡提供一些辅助信号。

Result The cultured DC from mouse bone marrow displayed the typical morphological characteristics of DC. Immature DC, which had high expression in CD11c and low expression in MHCⅡ and CD86, could phagocytize antigen. Mature DC, which had high expression in CD11c, MHCⅡ and CD86, could stimulate allogenic mixed lymphocyte proliferation.

未成熟DC的细胞表型为CD11c、MHCⅡ、CD86，具有极强的抗原吞噬能力；未成熟DC经LPS刺激培养后可转变为成熟DC，细胞表型为CD11c、MHCⅡ、CD86，可显著刺激同种异体混合淋巴细胞增殖。

ALA had obviously toxic effect on O. chinensis. Moreover, ALA caused the photoinactivation of AChE and GPx, which induced nerve transmission blocking and the capabilities to defend oxidation damage declining. Meanwhile, high-dose ALA could activate GSTs, which caused a feedback inhibition of insect to the phototoxic substance.

ALA对雌、雄中华稻蝗均有明显的毒性效应；ALA可引起AChE和GPx光失活，从而导致中华稻蝗神经传导受阻同时抵御氧化损伤的能力下降；高剂量ALA激活GSTs，可引发昆虫对光毒性物质的自身反馈抵御反应。
