The interaction of 5-fluorouracil-1-acetic acid (5FuAA) and its Cu! complex (5FuAACu) with DNA was also investigated by using spectral, viscometric, electrochemical and agarose gel electrophoresis methods. The results of interaction with DNA suggest that both 5FuAA and 5FuAACu can bind to DNA in a static electricity attraction mode. But the attraction of 5FuAACu is greater than that of 5FuAA.展开更多
目的将传统的骨髓采集方法与改良的方法进行比较,明确两种方法在细胞数量、组织污染情况和涂片染色背景的差异,为以后微核试验的应用提供参考。方法将处死小鼠的胸骨取出,一部分,使用传统的骨髓采集方法,将小鼠的骨髓挤压于含胎牛血清...目的将传统的骨髓采集方法与改良的方法进行比较,明确两种方法在细胞数量、组织污染情况和涂片染色背景的差异,为以后微核试验的应用提供参考。方法将处死小鼠的胸骨取出,一部分,使用传统的骨髓采集方法,将小鼠的骨髓挤压于含胎牛血清的载玻片上,常规涂片;另一部分,用1 m L注射器抽取胎牛血清100μL刺入胸骨中,将骨髓冲出,涂环形薄片。结果两种方法均能达到实验要求,但是改良骨髓采集法,采集的细胞数量更多,组织污染细胞少,制片背景更加清晰。结论与传统的骨髓采集方法相比较,改良的骨髓采集法更具优势,使微核试验的细胞计数简易。展开更多
