DNA content of cells in human buccal smears. A preliminary study. 1978

J Rowiński, and C Souchier, and J C Czyba

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.

D009061	Mouth Mucosa	Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.

D002610	Cheek	The part of the face that is below the eye and to the side of the nose and mouth.	Bucca,Buccas,Cheeks
D003720	Densitometry	The measurement of the density of a material by measuring the amount of light or radiation passing through (or absorbed by) the material.	Densitometries
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D012737	Sex Factors	Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from SEX CHARACTERISTICS, anatomical or physiological manifestations of sex, and from SEX DISTRIBUTION, the number of males and females in given circumstances.
