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.

结果："长动"对小鼠移植瘤模型和人体肿瘤裸鼠异种移植均有明显抑制作用，量效关系明显："长动"与放疗和化疗分别联合应用有明显的增效作用：作用机制研究结果：细胞毒性试验研究表明"长动"在体外对10株肿瘤细胞有明显的细胞毒性作用，量效关系明显；免疫学试验表明"长动"可以诱导荷瘤小鼠的脾淋巴细胞增殖，增强NK细胞的活性，对IL-2的产生无明显影响；"长动"在体外可明显诱导人体肝癌QGY细胞凋亡，使细胞阻滞于G0-G1期。

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.

使用小鼠S180肉瘤、小鼠肝癌H22实体瘤和小鼠Lewis肺癌模型，以及人体肝癌QGY和人体肠癌LOVO裸鼠异种移植模型，进行"长动"的抗肿瘤药效学研究：用小鼠肝癌H22进行"长动"合并放疗和化疗的增效作用研究；用MTT法进行"长动"对肝癌QGY、肠癌LOVO、肺癌A549、乳腺癌MCF-7、小鼠白血病P388等10株人体和动物肿瘤细胞的体外细胞毒性作用研究；用淋巴细胞转化试验、小鼠NK细胞活性试验、小鼠胸腺细胞增殖法分别测定"长动"对荷Lewis肺癌小鼠的脾淋巴细胞增殖的影响、自然杀伤细胞活性的影响和对小鼠产生白介素-2(IL-2)的影响；用流式细胞仪PI单染色法进行"长动"对人体肝癌QGY细胞的体外诱导凋亡作用和对肿瘤细胞周期的影响的研究。

At the same time, his government has been responsible for serious encroachments on fundamental rights, a shift in the balance of power from individual liberty and towards state control; a similar shift as between the executive and the judiciary; entrenchment of xeno-racism and, in particular, erosion of the idea of universality of human rights.

在同一时间内，他的政府一直在应对严重侵犯基本权利，改变了权力平衡，由个人自由与对国家的控制；类似移之间，行政机关与司法机关；巩固异种种族主义和，尤其是侵蚀的思想，人权的普遍性。

The hEGcs can be used in heterotransplantation ,and the transplanted cells migrate from the epicardium to the myocardium and differentiate into cardiac myocytes gradually.

On the basis of observation on the denucleation process of mammalian erythroid cells in vito and in vitro, the present study was designed to investigate the regulatory effect and its mechanism of mammalian erythroblast cytoplasmic factor on malignant phenotype and gene expression of hybrid cells formed by cellular engineering fechnique of cell hybridization between the mouse plasmocytomas SP (2/0) cell line and rat erythroblasts.
