Changdong" showed a noticeable enhancive effect when it was co-administrated with other anti-tumor agents or when it was co-applied with radiotherapy. The action mechanism study showed that an apparent cytotoxic effect of "Changdong" on ten tumor strains in vitro with a quantity-effect relationship was observed. Immunity experiment showed that "Changdong" could induce proliferation of spleen lymphocyte in mice bearing tumor and could improve NK cell" s activity, whereas has no impact on IL-2" s reproduction. It was also noticed that "Changdong" could induce human liver cancer QGY" s apoptosis in vitro, and it happened mainly on G0-G1 phase.

Five models were used to investigate the "Changdong"" s anti-tumor effect: mice S180 sarcoma solid model, mice liver cancer H22 solid model, mice Lewis lung cancer model, as well as human liver cancer QGY and colon cancer LOVO implanted in naked mice; mice liver cancer H22 was also used to evaluate the enhancive effect of "Changdong" when it was co-applied with other anti-tumor agent or with radiotherapy; The "Changdong"" s cytotoxic effect in vitro on such tumors as QGY, LOVO, lung cancer A549, breast cancer MCF-7, as well as mice leukemia P388 was observed through MTT method. And investigate the effect of "Changdong" on proliferation of spleen lymphocyte, on activity of NK cell and on synthesis of IL-2 in mice bearing Lewis lung cancer, respectively. With propidium iodide straining, cell aigptosis and cell circle were analyzed by flow cytometry. Result:"Changdong" has an evident tumor inhibitive effect on mice tumor model as well as human tumor implanted in naked mice with a quantity-effect relationship.

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。
