In vivo efficacy of Ca-EE in an atopic dermatitis (AD) mouse model. (a) Schematic diagram of the AD mouse disease model. Ca-EE was topically applied to skin once a day for 7 days before DNCB treatment. AD was induced by DNCB treatment for an additional 21 days. (b) Ears of AD-induced mice. Photographs were taken at day 28. (c) The dermatitis score was determined by changes of itching, erythema, and dryness of lesion (Criteria 0: no change, 2: slight, 4: moderate, 8: severe change). (d) The ear thickness of mice was measured by dial thickness gauges. (e) The body weight of mice was measured every 3 days. (f) The water content (%) of skin was evaluated using an SK-IV digital moisture monitor. ##
