Abstract Subject headings

Using a combination of induced skin blistering and collection chambers permits dynamic studies of the aseptic inflammatory reaction in humans. Blisters filled with interstitial fluid can be generated by applying negative pressure to normal skin for up to 2 h. The blisters are subsequently denuded to form superficial "skin windows" that are well defined with regard to area and depth. The denuded areas are covered with a separate collection chamber filled with a suitable medium and left for 18-24 h. During this period, neutrophils and inflammatory agents accumulate in the chamber medium, and sequential events in the inflammatory process can be studied by repeated sampling. Inactive medium or isolated peripheral blood cells from the same individual can be used as controls for both cellular functions and the pro-/anti-inflammatory mediators that are generated or released.
