摘要
应用多功能图像分析仪，检测了鼠Ｗ２５６移植性肿瘤细胞ＤＮＡ含量，并同时测定细胞ＡｇＮＯＲｓ计数，探讨紫外光血液辐照疗法（ＵＢＩ）对放射治疗的增敏作用。结果表明；光量＋放疗组肿瘤细胞ＤＮＡ含量为５．３４±１．０９Ｃ，ＡｇＮＯＲｓ计数为２．２４±０．４３；单纯放疗组肿瘤细胞ＤＮＡ含量为７．８３±０．８６Ｃ，ＡｇＮＯＲｓ计数为５．３５±０．８４；前者ＤＮＡ含量及ＡｇＮＯＲｓ计数显著小于后者（Ｐ＜０．０５）。表明ＵＢＩ对放疗恶性肿瘤有明显的增敏作用。
bstrct To study the enhanced effect of ultraviolet blood irradition (UBI)on therapy,DNA contents and AgNORs of w256 mice transplating neoplasm were tested.the results showed that DNA contents of UBI and radiotherapy group was 5 34±1 09C. AgNORs of That was 2 24±0 43;DNA content of simple radiothereapy group was 7 83±0 68C, AgNORs of that was 5 35±0 84;DNA contents and AgNORs of the front were significantly lower than those of the latter.It suggested that UBI has significantly enhanced effect on radiotheraby.
