objective to study the anti-tumor activity and enhancing immune effect of phellinus linteus.methods the anti-tumor activity of phellinus linteus was estimated by the longevity of eac mice,the immune effect of tumorous mice was tested by the experiment of carbon particle expurgation and the il-2 concentration in serum of tumorous mice was determined by elisa.results phellinus linteus can prolong eac mouse's life and can increase the il-2 concentration in serum of tumorous mouse but can't affect the immune effect of tumorous mouse.conclusion chinese hurb phellinus linteus possess some antitumor power for tumor-loaded mice,but further research is needed.

目的 观察桑黄对肿瘤的抑制作用及对机体免疫功能的影响。方法以小鼠艾氏腹水癌的生命延长率评价桑黄的抗肿瘤作用，以炭末廓清实验观察荷瘤小鼠非特异性免疫功能，以elisa法测定荷瘤小鼠血清il-2浓度。结果桑黄对eac荷瘤小鼠的生存时间有延长作用，对荷瘤小鼠血清il-2浓度有提高作用，对荷瘤小鼠非特异性免疫功能无明显影响。结论中药桑黄对荷瘤小鼠具有一定的抗肿瘤能力，作用的强度和作用机制的深度还有待进一步研究。

And the repression of NO-induced cell death with Ppbi-1 overexpression in transgenic lines was apparent even at SNP concentrations up to 1mM.In addition work,we found that most of suspension cells treated with 0.5mM SNP can be stained by Sytox green,some PCD morphologic characteristics such as chromatin condensation and margination can be observed.DNA Ladder was also detected with these cells.As to the control and the cell treated with 0.5mMSNP+20μM Est,the above-mentioned characteristics can\'t be detected.

对0.5mM SNP和0.5mM SNP+20μM Est处理的飞廉转基因细胞培养三天后用特异性核染料sytox染色，0.5mMSNP单独处理的细胞大部分核被染色，而且细胞核出现了核凝聚、以及染色质边集等凋亡细胞的特征；提取细胞DNA电泳分析，观察到了DNA LADDER，这说明，该细胞可能已经发生凋亡，而Est诱导Ppbi-1基因表达的细胞均未出现这些凋亡特征。
