Results Stable drug-resistant SW1990/GZ cell strain was established by culturing with gemcitabine for 9 months. The morphology and growth characteristics of the cell strain changed remarkably. The cells shrinked and became rounder; its endoplasm expanded; granular substances increased; and the doubling-time was prolonged. Resistance of the cell line to gemcitabine, fluorouracil, adriamycin, and mitomycin significantly increased. The TrxR activity of the drug-resistant cells was increased markedly.

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.

Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.
