Abstract

The authors studied 100 Koreans for sex determination using the sex chromatin of the epithelial cells from the oral mucosa according to Marberger's method. Turbid suspensions obtained by scraping the buccal mucosa were used; these were stained with a modified Feulgen technic for DNA.
Summarizing our observations, the percentage of the sex chromatin in the nuclei of the epithelial cells showed a remarkable difference between the male and feamle of 23.6%. The authors confirmed the fact that the method of oral smear which had already been introudced by Marberger and his associates (1955) might be applicable to the Korean, also.
