HpD在诊治癌症过程中的光敏机理

本文就目前提出的几种HpD的光敏机制,通过离体培养的癌细胞,在HpD的浓度接近诊治癌症的临床条件下进行了比较.初步推断在HpD-光敏诊治癌症过程中起主导作用的机制仍是单态氧.     

SOFT X-RAY IMAGES OF CHROMOSOMES WITHIN INTACT TUMOR CELLS TREATED WITH COLCHICINE

In order to avoid any possible effect of separating procedures from intact cell on morphologic structure of the chromosomes, cultivated Hep-2 tumor cells were treated with colchicine and observed by soft X-ray contact microscopy for the first time. The fine structures of chromosomes are more clear with stereo features. The thread-like and coarse granular structures twine and tangle up together within chromosome masses which can not easily be revealed in Wright's stained sample by light microscope or osmium stained sample by transmission electron microscope     

细胞样品的高分辨率软X射线接触显微术图像的研究

在建立适于软Ｘ射线接触显微术（ＳＸＣＭ）观察细胞样品制备方法的基础上，以培养的肿瘤细胞为生物样品，应用细聚焦软Ｘ射线光源进行ＳＸＣＭ研究，获得了分辨率优于２８ｎｍ的高质量肿瘤细胞ＳＸＣＭ图像。
