The PKC family is subdivided into three groups; the classical PKC members are Ca〓 and diacylglycerol dependent, the novel PKCn are Ca〓-independent but diacylglycerol dependent and the atypical PKCs are not activated by Ca〓and diacylglycerol in vitro.

丝裂素活化蛋白激酶是一族在脊椎类动物体内广泛存在的蛋白质丝氨酸/苏氨酸激酶，是目前发现的最主要的一个生长信号调节蛋白，是细胞内多种促细胞增殖信息传递的共同通路或称会聚点，是细胞表型变化和增殖的蛋白激酶。

The SGC-7901GA cells and control cells SGC-7901Neo were cultured in vitro,and then were respectively injected into the endermic tissue of 6-weeks-old BALB/C node mice to create the animal models of tumor. The neoplasia and growth of tumor were observed. Use MTT method to detect the difference of growth capability of two kinds of cells in vitro.

The results showed YYSXF could raise survival rate of the mice after irradition, increase activity of superoxide dismutose and reduce quantity of the lipid peroxide in liver and red blood cell, extenuate micronucleus formating in V79 4 cell, promote unscheduled DNA synthesis and induce production of interleukin 2 in spleen cells and protect bone marrow cells in mice.

结果表明养阴生血饮能提高致死剂量照射动物30d和小剂量多次照射60d及荷瘤小鼠1次照射后20d的存活率；能增加超氧化物岐化酶的活性；降低过氧化脂质的水平；减少细胞的微核形成；促进脾细胞DNA修复；诱导脾细胞产生白细胞介素－2；保护骨髓造血功能

The NK cytotoxicity was inhibited in RD-10 cells with high expression of MHC class Ⅰ molecules, but the γδT cells cytotoxicity was same among the three groups. Then the tumorgenicity of these tumor cells were determined in nude mice heterograft model in vivo.

动物接种肿瘤的实验结果表明，Balb/c裸鼠在接种野生型RD细胞、RD-neo细胞及RD-10细胞(低表达IL-15)后，各组小鼠肿瘤生长在体积和瘤重方面并无显著性差异。

In currence, se- GSH- PX activity have been been used as a standard of Selenium nourishment, GSH- PX is an extremely important protection enzyme in anti oxida- tive defend system of organize and cell of animal.It clear hydroxy radical and hyperoxide in cell respir- ation metabolism reaction ,thereby, mai- ntain cell's normal physiological function, prote- ct biomembrane and biomacromolecule from oxidative damage.If the activity is high or not, effect the ab- ility that the organize clears hyperoxize lipi- d ,directly.

目前，含se-GSH-PX活性已被作为se营养状况可一个指标，该酶是动物组织细胞抗氧化防御系统中一个极为重要的保护性酶，它是以还原型GSH为底物的谷胱甘肽参与的过氧化反应，清除细胞呼吸代谢反应过程产生的羟自由基和过氧化物，从而使细胞能维持正常的生理功能，保护生物膜和生物大分子结构免受氧化损伤。
