Summary
After the removal of collagen and ground substance by autoclaving tissue samples and subsequently applying the SEM technique, a dense meshwork of elastic fibres could be demonstrated in the dermis of the pig (wild boar, domestic pig, miniature pig).
The abdominal body region showed relatively large amounts of elastic fibres compared to the back and the lateral body wall. In comparison with the papillary layer and the mid-dermis, thicker elastic fibres predominated in the deeper dermis; thinner fibres were attaching to the epidermis and the pilosebaceous units. The results are discussed in relation to corresponding investigations on the human dermis.
Zusammenfassung
Nachdem durch Autoclavierung kollagene Fasern und Grundsubstanz entfernt worden waren, konnte in Hautproben mit Hilfe der SEM-Technik ein dichtes Netzwerk von elastischen Fasern in der Dermis des Schweines nachgewiesen werden. Das Hautmaterial stammte vom Wildschwein, vom Hausschwein sowie vom Miniaturschwein.
Im Vergleich mit Rücken und Flanke zeigte die Bauchregion den relativ größten Anteil an elastischen Fasern. Dickere elastische Fasern fanden sich vorwiegend in der tieferen Dermis, während dünnere Fasern mehr im Stratum papillare und in der mittleren Dermis anzutreffen waren. Dünne Fasern waren besonders in Anheftung an die Unterseite der Epidermis und die Außenseite der Haarfollikel zu beobachten.
Die Ergebnisse werden im Zusammenhang mit Beobachtungen aus entsprechenden Untersuchungen an der Dermis des Menschen diskutiert.
