[Evaluation of human skin function in a sealed room by a chromatographic method].

Gas-liquid chromatogrophy was used to study the skin and sebum cutaneum of 6 male test subjects (aged 45-55) before and after 30-day enclosure. The greatest changes were seen in the composition of free fatty acids of lipids of the facial skin (increase of palmito-oleic acid). The lipid composition of the sebum cutaneum of the healthy subjects differed from that of the acne-bearing subjects. It is recommended to use the ratio of palmitic acid to palmito-oleic acid as a measure of changes of fatty acids in the sebum cutaneum of healthy people in an unusual environment.
