采用DNA和蛋白质吸收带的Kubelka-Munk光谱函数对离体的人正常胃、未分化胃腺癌、胃鳞状细胞癌和低分化胃腺癌的上皮组织进行鉴别诊断。实验采用带积分球附件的分光光度计获取组织的漫反射光谱。结果表明：在250～650 nm，人胃的上皮组织的癌变导致未分化胃腺癌、胃鳞状细胞癌和低分化胃腺癌等的上皮组织的Kubelka-Munk光谱函数f(r∞)及其对数log[f(r∞)]的平均值在DNA吸收带(...
DNase γ-dependent and -independent apoptotic DNA fragmentations in Ramos Burkitt's lymphoma cell line
DNase γ-dependent -independent apoptotic DNA

DNA fragmentation is a biochemical hallmark of apoptosis. Several endonucleases, including CAD/DFF40 and endonuclease G, are implicated in DNA fragmentation. DNase γ has also been considered to be one...
FCM在横纹肌肉瘤细胞周期和DNA倍体分析研究中的应用
流式细胞术 横纹肌肉瘤 DNA倍体
2009/3/25
目的：以20年来的病理资料存档完整的90例横纹肌肉瘤石蜡标本为研究对象，研究横纹肌肉瘤细胞的细胞周期和DNA倍体变化与临床病理分型之间的相关性。方法：荧光染料使用碘化丙啶（PI），PI可以和DNA双链结合，细胞中PI染料的含量与DNA的含量成正比，因此PI的含量就间接反映出细胞中DNA的含量和周期分布情况。结果：二倍体8例（8/90 8.89%），次二倍体4例（4/90 4.44%），超二倍体38...
