Effect of cleansing of keratin plugs on nostril and cheek by hydrogen warm water.

Note: (A) Stereoscopic images of cleansed and transferred keratin plugs on cheek by hydrogen warm water bathing with compared to normal warm water bathing. Representative plugs are shown by arrows. This experiment was performed on female at the age of 36 years and male at the age of 40 years. Scale bars: 1 mm. (B) Scanning electron microscopic images of cleansed and transferred keratin plugs (indicated by arrowheads) on cheek by hydrogen warm water bathing with compared to normal warm water bathing. This experiment was performed on female at the age of 36 years and male at the age of 40 years. Scale bars: 200 μm. (C, D) Cleansing of keratin plugs on nostril and cheek by hydrogen warm water bathing with compared to normal warm water bathing. Cleansing effects were assessed as the area (C) and number (D) of cleansed keratin plugs by stereoscopic microscopy shown in A and scanning electron microscopy shown in B. These experiments were performed in female at the age of 36 years and male at the age of 40 years. Date are expressed as the mean ± SD, n = 4. *P < 0.05, vs. hydrogen warm water.
