本文采用Feulgen-DNA含量细胞分光光度术动态地测量了林县不同胎龄人的食管上皮细胞DNA含量及其染色体倍性的精确变化,DNA含量及相关细胞频数关系用直方图显示吸收光度量。结论是:胎龄愈高,DNA含量愈集中分布,最大峰值的G_1的造型愈高,DNA值的标准差(s)和标准误(s_?)愈小。DNA含量在2～4C范围,符合一个增殖细胞群体的特征。食管上皮的增殖和分化情况由细胞分光光度计所测量的DNA含量的分级依据和细胞形态学特征所反映,同时探讨了在增殖与分化“失常”的微细形态学改变之前可能显示出精微的DNA含量的改变。
In this paper, Feulgen-DNA content cell spectrophotometry was used to dynamically measure DNA content and chromosome ploidy of Linxian different gestational age human. The relationship between DNA content and related cell frequency was shown by histogram to absorb light. The conclusion is that the higher the gestational age, the more concentrated the DNA content, the higher the peak shape of the G_1 shape, the smaller the standard deviation (s) and standard error (s_?) Of the DNA value. DNA content in the 2 ~ 4C range, in line with the characteristics of a proliferating cell population. Proliferation and differentiation of esophageal epithelium is reflected by the grading of DNA content measured by the cell spectrophotometer and morphological features of the cells as well as by the possibility of showing subtle DNA prior to fine morphological changes that “proliferate” and “differentiate” in differentiation Changes in content.
