Summary

The effect of long-term ultraviolet irradiation on the connective tissue of the skin was investigated in 25 naked (Ng/-) mice which received a total daily radiant dose of 40±2 J/cm2 for a period of 8.5 months. The produced alterations were very similar to those found in actinic elastosis of humans, as assessed by histologic and electron-microscopic criteria.

Zusammenfassung

Der Einfluß chronischer UV-Lichteinwirkung auf das dermale Bindegewebe der Nacktmaus (Ng/-) wurde licht- und elektronenmikroskopisch untersucht (25 Tiere; Dauer der Bestrahlung 8,5 Monate; tägliche Strahlendosis 40±2 J/cm2). Die induzierten Bindegewebsveränderungen entsprechen weitgehend dem Bild, wie es bei der menschlichen aktinischen Elastose angetroffen wird.
