Zusammenfassung Haut von Kindern verschiedenen Alters wurde chemisch untersucht. Es wurde der Gehalt an Wasser, fettfreier Trockensubstanz, Gesamtstickstoff, Oxyprolin, Hexosamin, Asche, Calcium, Magnesium, Phosphorsäure, Eisen und Kupfer bestimmt. Es zeigte sich, daß sich der Gehalt an einigen dieser Komponenten mit dem Heranwachsen der Kinder auf charakteristische Weise ändert. Die Ergebnisse dieser Untersuchungen werden mit von anderen Autoren veröffentlichten Resultaten verglichen.
Notizen:
Summary Samples of skin from children of different age were analysed by chemical methods. The content of water, fatfree dry residue, total nitrogen, hydroxyproline, hexosamine, total minerals, calcium, magnesium, phosphate, iron and copper were determined. It was found that the degree of hydratisation is highest in the skin of babies; it diminishes quickly during the first year of life and much more slowly till the age of about five years. Nitrogen content increases slowly with age and in the skin of young children a quickly increasing percentage of the total nitrogen is collagen nitrogen. Mineral content, particularly phosphorus and magnesium content, are much higher in the skin of babies than in that of older children. Results of our analyses differ in several respects from those of other authors. They seem to indicate that the chemical composition of children's skin undergoes changes which to the greatest part take place during the first year, but continue for several years.
