  • Atopic dermatitis is characterized by chronically pruritic and inflammatory dermatitis. In this study, we investigated the effect of Platycodon grandiflorum including platycodin D (PG-Platycodin D) in an atopic dermatitis-like mouse model. An atopic dermatitis-like skin lesion was induced by repeated treatment of 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin of ICR mice. The efficacy of PG-Platycodin D was tested by observing scratching behavior, the skin severity score, and histopathologic analysis. PG-Platycodin D reduced the DNCB-induced increase in scratching behavior and the skin severity score. In addition, histopathologic analysis revealed a reduction in the thickening of the epidermis in the PG-Platycodin D group. These results may contribute to the development of a therapeutic drug for the treatment of atopic dermatitis.

  • The efficacies of anti-atopic preparations were investigated in hairless mice suffering from 2,4-dinitro-chlorobenzene (DNCB)-induced atopic dermatitis-like lesion. Solid lipid nanoparticle (SLN) containing ceramide and astaxanthin was prepared by a melt-homogenization method using Aminsoft-CT 12 (Cocoyl glutamate) as an emulsifier. And then, the SLNs were coated with silk fibroin (SF) by taking advantage of an electrostatic interaction between the surface of SLNs and SF. SLNs were included in lotion (FL) and cream (FC) types of preparations. Anti-atopic efficacies of the preparations were investigated in terms of appearance of skin surface, spleen index, serum IgE level, and serum cytokine level. SLN-containing preparations suppressed IgE production and IL-4 expression, but promoted $IFN-{\gamma}$ expression.

  • Atopic dermatitis, also called congenital fever, is a allergic eczema of chronic itching disease. It is a recurrent and familial disease and appears on a wide age group from infant to adult. It is very common, and the ratio of occurrence is about $9{\~}l2\%$ of a child. However. it is showing trend of continuous increase by social and natural environment, food culture, and life style, recently. The human skin plays a barrier role against a physical and chemical stimulus from external environment. According to the latest study, the decreased amount of ceramide in horny layer impairs the bier function and moisture-maintaining function of skin in atopic dematitis patient. Ceramide is a kind of the sphingolipid in which a fatty acid is connected to sphingosin. Ceramide constitutes about $40\%$ of total lipid between keratinocytes and has the function of defense wall and building regular structure to suppress moisture vaporization in horny layer. In horny layer of skin a comified cell is composed of multi-layer structure of a brick shape, and, as for this cornified cell, it is strongly connected by ceramide, cholesterol, and free fatty acid. Here, we described the effects of a cream containing ceramide on the recovery of skin harrier function of atopic dermatitis patient. The safety and efficacy of latex and liquid formula were evaluated as cosmetics for atopic dermatitis. The latex products was composed of intercellular lipid components-ceramide, cholesterol, and free fatty acid-to restore skin barrier function in atopic dermatitis patients. The liquid one contained beta-glucan, magnolia extracts, and licolice extracts, which have skin immunomodulatory and anti-inflammatory effects. It is also confirmed that their possibility on new cosmetic market of atopic dermatitis.

  • With the advent of 'The Forth Industrial Revolution' and the growing demand for quality of life due to economic growth, needs for the quality of medical services are increasing. Artificial intelligence has been introduced in the medical field, but it is rarely used in chronic skin diseases that directly affect the quality of life. Also, atopic dermatitis, a representative disease among chronic skin diseases, has a disadvantage in that it is difficult to make an objective diagnosis of the severity of lesions. The aim of this study is to establish an intelligent severity recognition model of atopic dermatitis for improving the quality of patient's life. For this, the following steps were performed. First, image data of patients with atopic dermatitis were collected from the Catholic University of Korea Seoul Saint Mary's Hospital. Refinement and labeling were performed on the collected image data to obtain training and verification data that suitable for the objective intelligent atopic dermatitis severity recognition model. Second, learning and verification of various CNN algorithms are performed to select an image recognition algorithm that suitable for the objective intelligent atopic dermatitis severity recognition model. Experimental results showed that 'ResNet V1 101' and 'ResNet V2 50' were measured the highest performance with Erythema and Excoriation over 90% accuracy, and 'VGG-NET' was measured 89% accuracy lower than the two lesions due to lack of training data. The proposed methodology demonstrates that the image recognition algorithm has high performance not only in the field of object recognition but also in the medical field requiring expert knowledge. In addition, this study is expected to be highly applicable in the field of atopic dermatitis due to it uses image data of actual atopic dermatitis patients.

  • Atopic dermatitis (AD) is a chronically relapsing inflammatory skin disease that often has asthma and allergic rhinitis. Magnesium salts, the important component of minerals in Dead Sea water, are known to exhibit beneficial effects in inflammatory disease. Favorable effects of magnesium ions and sea water treated to the skin of patients with contact dermatitis have been reported. But histological and immunological investigations are insufficient. This study was performed to examine the inhibitory effect of magnesium-rich sea mineral water on the development of AD-like skin lesions in hairless mice. AD-like skin lesions are induced by the repeated application of 2,4-dinitrochlorobenzene (DNCB). Local application of magnesium-rich sea mineral water on hairless mice skin applied with DNCB inhibited the development of AD-like skin lesions as exemplified by a significant increase in skin hydration (p<0.01), and a decrease in epidermal water loss (p<0.01). Serum IgE level was also significantly decreased (p<0.01). These results suggest that magnesium-rich sea mineral water inhibits the development of DNCB-induced AD-like skin lesions in hairless mice. These observations indicate that magnesium-rich sea mineral water may be alternative and assistant substances for the management of AD.

  • Objective : It is well known that patients with atopic dermatitis are prone to cutaneous infections. Especially Staphylococcus aureus has been regarded as having an influence on atopic dermatitis. We observed and treated a case of an adult atopic dermatitis patient with sepsis by cooperation of east-west medicine. We present this case because there were no former reports of atopic dermatitis with sepsis treated by cooperation of east-west medicine. Method : We used herbal medication, acupuncture, herbal wet dressing combined with antibiotics and analgesics for 19 days. Atopic dermatitis grade was determined using SCORAD index. Result : The SCORAD index was lowered 32.3 at discharge than before of which the SCORAD index was 62.5 at admission. Other systemic inflammatory response such as fever, pus was also resolved. Conclusion : From this result, we suggest that herbal therapy associated with antibiotic therapy were shown to treat atopic dermatitis with secondary infection effectively.

  • Malassezia spp. was isolated from the skin lesion of a South American Sea Lion (Otaria byronia) in South Korea. Colonies were cream to yellowish with smooth margin on Sabouraud dextrose agar without lipid supplements. Yeast cells were ovoid to cylindrical in shape and budding daughter cells from broad base. We conducted 26s rRNA sequencing to specify the strain of the yeast and found out this isolate highly matched with Malassezia pachydermatis isolated from canine otitis. The pulse therapy of oral itraconazole was very effective in this case. M. pachydermatis has a wide range of host animals but this is the first report in a sea lion in South Korea.

  • Patients with atopic dermatitis, an intractable disease, suffer uncontrollable psychological distress as well as various symptoms in their skin. Recent findings showed that mental factors such as stress may play a role in the disease and that some techniques for alleviating psychological problems were efficacious in the atopic dermatitis. Therefore, we proposed the mind-body medicine that has been used to decrease the negative influences of stress and to cure psychosomatic disorders as an additional remedy for the atopic dermatitis. A model on the therapeutic effect of mind-body medicine and some qualities of practician also were discussed.
