The DNA content of the cells from human buccal smears, stained by the Feulgen method, was estimated by absorbtion microdensitometry using a Quantimet 720 D image analyser. It was concluded from measurements that most of the cells in buccal smears contained 2C DNA; however, among the cells from male donors a substantial proportion of cells (about 17%) contained less than 2C DNA. This difference between population of male cells versus female cells was statistically significant. The mean value of DNA content was estimated to be 7.7% lower for male cells than for female cells. The conclusions are preliminary because relatively small samples of cells have been measured.
采用福尔根染色法对人颊黏膜涂片细胞的DNA含量进行测定，使用Quantimet 720 D图像分析仪通过吸收式显微密度测定法进行评估。测量结果表明，颊黏膜涂片中的大多数细胞含有2C DNA；然而，在男性供体的细胞中，相当一部分细胞（约17%）的DNA含量低于2C。男性细胞群体与女性细胞群体之间的这种差异具有统计学意义。据估计，男性细胞的DNA含量平均值比女性细胞低7.7%。由于所测量的细胞样本相对较小，这些结论只是初步的。
