In studying a 2-dimensional symplectic map, the exponential law and algebraic law are observed in the diffusion of orbits in the phase space. The diffusion time
目的 通过噬菌体随机七肽文库筛选出与体内肺癌组织特异结合的七肽,并制备肽类肺癌早期诊断试剂.方法 通过噬菌体展示体内筛选技术获得与肺癌特异结合的噬菌体,进行序列测定,合成特异结合的多肽,125I标记后经静脉注射入小鼠体内,观察其在小鼠Lewis肺癌模型中的分布.结果 通过4轮筛选获得了QYGQFAY七肽,该七肽经125I标记后可以很好地与肺癌组织特异结合,在体内2 h左右与肿瘤结合得最充分,而且体
