Results: Tyroserleutide can significantly increase the life span of H22 tumor-bearing mice by 50-70% in dosages of 20ug/kg/d-80ug/kg/d,specially the high dosage of 80ug/ml can significantly increase the life span by 69.24%; Tyroserleutide can inhibit the growth of transplanted hepatocellular tumor BEL-7402 in nude mice,the rate of tumor inhibition was25-50% in dosages of 40-320ug/ml ,the inhibition rate of 160ng/ml was 44.03%; Tyroserleutide could inhibit the growth of H22 and BEL-7402 tumor in a dose-dependent manner. Simultaneously, tumoricidal activity of tyroserleutide against BEL-7402 cell line in vitro was observed hinger when compared with the control group(P.05).The inhibition effect of 72hrs was higher than 24hrs,48hrs,96hrs.And specially the high dosage of 160ug/ml can significantly inhibit growth of tumor cell by 19.36%. Tyroserleutide can activated PEM and marked enhance cytotoxicity andphagocytosis functions in vitro and in vivo. The OD values of cytotoxicity were observed hinger when compared with the control group(P.05).The cytotoxicity of macrophages activated by tyroserleutide against BEL-7402 and B16-F10 was 35.58%,61.2% in vitro and21.39%,47.63% in vivo. The cytotoxicity rate of nude mice PEM was 32.86%,73.07% in vivo. Furthermore, tyroserleutide alone could stimulated the production of IL-1B TNF- a and NO by M . Tyroserleutide and LPS could synergistically activated M producing more cytotoxicity effectors. Conclusion: Tyroserleutide had inhibition functions against hepatoma carcinoma .Its possible mechanisms were related to the affect that Tyroserleutide could inhibit tumor cell directively and induce tumor cells apoptosis or death effectively.

The Food and Drug Administration of USA hasapproved the use of this topical medicine for treatment of different malignant andpremalignant tumors such as actinic keratoses and basal cell carcinoma. Althoughimiquimods exact mechanisms of action in neoplastic diseases has not yet been fullyelucidated, animal and human studies have shown its ability to enhance the productionof cytokines such as interferon-, interleukin-12, and tumor necrosis factor- though conjugations with Toll like receptors on the surface of dendriticcells of the monocyte-macrophage lineage.

有关咪喹莫特抗癌作用的具体机制仍不十分明了，一般认为，咪喹莫特主要是通过与免疫相关细胞表面的Toll样受体结合、促进IFN-α、TNF-α、IL-12等多种前炎症细胞因子的分泌，进而激活天然与获得性免疫反应的方式发挥抗癌作用；进一步的研究发现，咪喹莫特尚能选择性的抑制某些皮肤肿瘤细胞的增殖并诱导其凋亡，提示增殖抑制和诱导凋亡可能是评价咪喹莫特抗肿瘤作用的重要指标和机制。

However, an efficient expression system is not limited to secreting protein, keeping the ability of genetic and replication, it also has high expressive element.

当然，一套好的表达系统不仅要能分泌蛋白质，保持遗传和分裂的稳定性，还应该有一些高效表达的元件。

I concluded that these proteins found in the tea must consist of various enzymes secreted by the yeast and bacteria to break down the large molecules of different nutrients in the tea which usually cannot enter cells directly, for example sucrose and caffein.

我得出结论，在茶中发现的这些蛋白必须包括酵母和细菌分泌的各种酶去破坏茶中的不同营养素大分子，通常它们是不能直接进入细胞的，例如蔗糖和茶精。

In this article, the effect of different water pH (pH 5, 6, 7, 8, 9)on the secretion of nacre of freshwater pearl mussel Hyriopsis cumingii were studied with histochemical methods and transmission electron microscopy.

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。

However, the nodule could be induced by germfree liquid that filtered from the rhizobia, cultural medium. It is proposed that the some soluble substances excreted by the cultured rhizobia, can stimulate the plant to form the root nodules. Nevertheless, the nodules formed by this way can't produce haemachrome. So the nodules show light green or white. And there are starch in them.

但根瘤的形成还可由培养根瘤菌的无菌滤液诱导形成，这充分说明根瘤菌生长过程中分泌的某种可溶性物质具有刺激植物形成根瘤的作用，但这种根瘤由于不能形成豆血红蛋白而呈淡绿色或白色，且根瘤中有大量淀粉积累。
