摘要:

Previous studies have shown that acute disruption of the cutaneous permeability barrier by acetone results in an initial rapid phase of repair followed by a later, slower phase. In the present study, we demonstrate that manipulations which disrupt the barrier by other mechanisms, such as tape stripping or detergent treatment, have a similar pattern of barrier repair. In all three models, the return of lipid to the stratum corneum parallels the normalization of barrier function, and occlusion immediately after disrupting the barrier blocks both the return of lipid and the normalization of function. Moreover, occlusion beginning 6-8 h following barrier disruption blocks the late, slower phase of repair, indicating that the late phase can be inhibited independently of the initial phase. Lastly, both severe and relatively minor perturbations of the barrier elicit a repair response with a similar kinetic pattern. In summary, the present study demonstrates that barrier repair responses are similar regardless of the etiology or extent of barrier disruption.
