Nuclear area and sex chromatin frequency in oral mucosa and hair root sheats of human females.

In 36 oral mucosa and in 25 hair root sheath slides nuclear area was measured in about 100 nuclei per slide. Within one slide no differences were found in nuclear area between nuclei with or without sex chromatin, or with a non-peripheral sex chromatin. No correlation was found between nuclear area and sex chromatin frequency, except for a weakly significant negative correlation between nuclear area and those nuclei without either peripheral or non-peripheral sex chromatin.
