Two occlusive, adhesive dressings--one hydrocolloid (absorptive) and one zinc-medicated (non-absorptive)--were studied regarding their occlusivity and effects when applied to normal human skin for 48 h. Both dressings reduced normal transepidermal water loss by about 70%. As documented by a 7-fold increase in the water loss beneath the dressings compared to untreated skin, water was retained in the stratum corneum by both dressings. No appreciable influence of either dressing on skin temperature was found. The skin surface pH decreased beneath the hydrocolloid while it increased beneath the zinc dressing.
研究了两种封闭性粘性敷料——一种水胶体（吸收性）敷料和一种含锌（非吸收性）敷料，观察它们应用于正常人皮肤48小时后的封闭性及效果。两种敷料均使正常经表皮水分流失减少了约70%。与未处理皮肤相比，敷料下方的水分流失增加了7倍，这表明两种敷料均能使角质层保留水分。未发现两种敷料对皮肤温度有明显影响。水胶体敷料下方的皮肤表面pH值降低，而含锌敷料下方的皮肤表面pH值升高。
