Objective : The purpose of this study is to expand our treatment field in oriental dermatology by understanding the patterns of outpatients who had visited the oriental hospitals located in Gangwon province. Methods : We studied 510 outpatients out of 2240 people from Sangji University Oriental Hospital(SUOH) and 333 outpatients out of 2030 people from Chuncheon Oriental Hospital(COH) from January 1, 2007 to December 31, 2009. We categorized the results by gender, age, disease types, residences, months and number of visiting times. Results : The results were as follows 1. Comparing the number of outpatients that had visited the hospital by gender in SUOH shows that female's visiting rate is 57% and male is 43%. In COH shows that female's visiting rate is 54% and male is 46%. 2. Most frequent visiting age group were 21-30 year-old group(30%) in SUOH and 11-20 year-old group(23%) in COH. 3. In regard to the monthly visiting period, January(13%) is the highest in SUOH and July(10%) is the highest in COH. 4. Regional distributions of the outpatients that had visited SUOH and COH show Wonju(73%) and Chuncheon(74%). 5. In terms of treatment methods, SUOH showed the external application(65%), herb medication(54%), and acupuncture(52%) while COH showed acupuncture(74%), the external application(69%), and herb medication(66%). 6. Visiting frequency of outpatients in SUOH showed that 1 time visiting cases were 51%. In COH case, 1 time visiting cases were 19%. 7. The most prevalent diseases were urticaria(15%), eczema(14%) acne(12%), and seborrheic dermatitis(11%) in SUOH and atopic dermatitis(27%), urticaria(20%), acne(16%), and psoriasis(10%) in COH. 8. Most outpatients had visited SUOH for 1 time(51%) and COH for over 11 times(32%) with the major 16 diseases. Conclusions : This study suggests that outpatients who had visited the department of oriental dermatology preferred to get a treatment for urticaria, eczema, atopic dermatitis and acne. Considering this aspect, it needs to improve current research to expand the oriental medical treatments further in dermatological field.

An about 5-month-old, female rabbit was presented with pruritus, alopecia and mucopurulent ocular discharge. On physical examination mild to moderate scales on whole body were observed. Dermatological lesions such as alopecia, erythema, papules, pustules and crusts were observed in the eyelids, nose, inner pinna, medial sites of four feet, metacarpal and metatarsal areas, and cranial site of left stifle joint. Also, mild conjunctivitis, blepharitis and keratitis were found. For extensive dermatologic diagnostic evaluation skin scraping, tape stripping, impression smear, combing, wood' light, bacterial culture and fungal culture were performed. Finally, Cheyletiella spp. was found by combing. Many heterophils and eosinophills were appeared in impression smear. The result of fungal culture was negative. Pasteurella spp was cultured. Definitive diagnosis of Cheyletiellosis and secondary Pasteurella spp infection were established. The rabbit was treated with 6 mg/kg of selamectin topically every two weeks and restricted in cage for one month. During one month of initial treatment, clinical signs such as pruritus, alopecia, scales, papules, pustules and crusts were remarkably improved. However, in spite of good therapeutic response of selamectin the rabbit was dead suddenly at 22 days after second administration of selamectin. This case showed that selamectin was possibly effective for cheyletiellosis in rabbit; safety of selamectin for rabbit was not identified.

A 6-month-old, male, American cocker spaniel was presented with severe pruritus, alopecia and head shaking. In physical examination generalized erythema, papules, scales and crust were observed. Otic discharge was dark-brown colored in both ear canals. After extensive dermatologic diagnostic evaluations, the infestation of scabies, ear mites, Malassezia spp, cocci were proved. Therefore, he was treated with selamectin 6 ㎎/㎏ which was applied to the skin in a single spot twice a week for 2 weeks in order to investigate the effect of selamectin on canine scabies and ear mites by this treatment protocol. When he was rechecked at 14th day after fourth being administered, scabies and ear mites wasn't seen. The dermatological signs, pruritus, papules were remarkably decreased and only slight scales were observed. After treatment of scabies and ear mites, the clavamox and koto-conazole was administered for cocci and Malassezia spp, respectively, for 1 week and topical therapy was initiated. with sebolytic and chlorhexidine shampoo once a week for 3 weeks. Two months later skin lesions were normal dermatologically and the hair was fully recovered. Despite of the expensiveness the selamectin is very effective in the dogs that infected by scabies and ear mites as this treatment protocol.

This study introduces a flexible approach to enhance skin permeation by using ethosomes with deformable lipid membranes as well as controllable sizes. To demonstrate this, a set of ethosomes encapsulating an anti-hair loss ingredient, Triaminodil$^{TM}$, as a model drug, were fabricated with varying their size, which was achieved by solely applying the different level of mechanical energy, while maintaining their chemical composition. After characterization of the ethosomes with dynamic light scattering, transmission electron microscopy, and deformability measurements, it was found that their membrane deformability depended on the particle size. Moreover, studies on in vitro skin permeation and murine anagen induction allowed us to figure out that the membrane deformability of ethosomes essentially affects delivery efficiency of Triaminodil$^{TM}$ through the skin. It was noticeable in our study that there existed an optimum particle size that can not only maximize the delivery of the drug through the skin, but also increase its actual dermatological activity. These findings offer a useful basis for understanding how ethosomes should be designed to improve delivery efficiency of encapsulated drugs therein in the aspects of changing their length scales and membrane properties.

A placebo-controlled double-blind ingestion study of a beauty supplement containing rice-derived ceramide was performed. Thirty three subjects who always tended to have rough skin due to dryness participated in the study. Dermatological diagnosis by physicians showed that the supplement significantly improved dryness and itching of the skin. On measurement of water content in the skin, the supplement was shown to significantly increase water content in the skin. On microscopic three-dimensional analysis of the epidermis, the supplement was shown to improve smoothness, exfoliation, and short-term ingestion of the supplement containing rice derived ceramide, which is very effective as skin beautifying food.

Background: Korean Red Ginseng (KRG) is a representative traditional herbal medicine with many different pharmacological properties including anticancer, anti-atherosclerosis, anti-diabetes, and anti-inflammatory activities. Only a few studies have explored the molecular mechanism of KRG-mediated anti-inflammatory activity. Methods: We investigated the anti-inflammatory mechanisms of the protopanaxadiol saponin fraction (PPD-SF) of KRG using in vitro and in vivo inflammatory models. Results: PPD-SF dose-dependently diminished the release of inflammatory mediators [nitric oxide (NO), tumor necrosis factor-${\alpha}$, and prostaglandin $E_2$], and downregulated the mRNA expression of their corresponding genes (inducible NO synthase, tumor necrosis factor-${\alpha}$, and cyclooxygenase-2), without altering cell viability. The PPD-SF-mediated suppression of these events appeared to be regulated by a blockade of p38, c-Jun N-terminal kinase (JNK), and TANK (TRAF family member-associated NF-kappa-B activator)-binding kinase 1 (TBK1), which are linked to the activation of activating transcription factor 2 (ATF2) and interferon regulatory transcription factor 3 (IRF3). Moreover, this fraction also ameliorated HCl/ethanol/-induced gastritis via suppression of phospho-JNK2 levels. Conclusion: These results strongly suggest that the anti-inflammatory action of PPD-SF could be mediated by a reduction in the activation of p38-, JNK2-, and TANK-binding-kinase-1-linked pathways and their corresponding transcription factors (ATF2 and IRF3).

The skin is colonized by a large number of microorganisms with a stable composition of species. However, disease states of skin such as acne vulgaris, psoriasis, and atopic dermatitis have specific microbiome compositions that are different from those of healthy skin. The target modulation of the skin microbiome can be a potential treatment for these skin diseases. Quorum sensing (QS), a bacterial cell-cell communication system, can control the survival of bacteria and increase cell density. Also, QS affects the pathogenicity of bacteria such as biofilm formation and protease production. In this study, we confirmed anti-QS activity of Amorepacific patented ingredients, which are Lactobacillus ferment lysate (using Lactobacillus plantarum APsulloc 331261, KCCM 11179P) through bio-reporter bacterial strain Chromobacterium violaceum. The purple pigment production of C. violaceum controlled by QS was reduced 27.3% by adding 10 ㎍/mL of Lactobacillus ferment lysate (freeze dried). In addition, the Lactobacillus ferment lysate increased growth of Staphylococcus epidermidis 12% and decreased growth of Pseudomonas aeruginosa 38.5% and its biofilm formation 17.7% at a concentration of 10 ㎍/mL compared to the untreated control group. Moreover, S. epidermidis was co-cultured with the representative dermatological bacterium Staphylococcus aureus in the same genus, the growth of S. epidermidis was increased 134 % and the growth of S. aureus was decreased 13%. These results suggest that fermented lysate using Lactobacillus plantarum APsulloc 331261 may be useful as a cosmetic ingredient that can control the balance of skin microbiome.

Objectives : Somatic symptoms after the exposure of psychological trauma frequently developed. However, the somatic symptoms are not covered under the diagnostic criteria of posttraumatic stress disorder(PTSD) in detail, although they are often associated with social and occupational functioning and patient-doctor relationships. The aim of this article is to highlight the potential mechanisms, the common manifestations, and the treatment of the somatic symptoms. Methods : This article studied the somatic symptoms searched using academic search engines like PubMed, Scopus, Google Scholar, KoreaMed and KISS from the earliest available date of indexing to March 31, 2016. Results : The mechanism of somatic symptoms after the exposure was described as psychological and physiological aspects. Psychological mechanism consisted of psychodynamic theory, cognitive behavioral theory, and others. Physiological mechanism involved changes in neuroendocrine and immune system, autonomic nervous system and central nervous system. Somatization associated with psychological trauma manifested various health conditions on head and neck, chest, abdominal, musculoskeletal, and dermatological and immune system. Few studies described the standardization of treatment for the somatic symptoms. Conclusions : Clinicians and disaster behavioral health providers should think of the accompanying somatic symptoms during intervention of psychological trauma and PTSD. Further studies are needed on the somatic symptoms seen in psychological trauma and PTSD.

Background: It is well known that skin cancer and precancerous disease develop more frequently in patients undergoing solid organ transplantation than normal populations in the normal population in Western countries. However, to date, the clinical and demographic features of skin cancer and precancerous disease after solid organ transplantation are not established in Asian countries. We evaluated the clinical and demographic features of primary skin cancer and precancerous lesions after solid organ transplantation and compared these with the trends observed in Western countries. Methods: We retrospectively reviewed the medical records of patients who underwent kidney, liver, heart, and lung transplantation between January 1995 and April 2017 and who developed skin cancer or precancerous lesions after transplantation. The various lesions observed were squamous and basal cell carcinoma, malignant melanoma, Kaposi sarcoma, Bowen's disease, and actinic keratosis. Results: We identified 4604 patients who received organ transplant. The mean age of patients was 44.8 years (male, 64.6%; female, 35.4%), and the sum of the person-year of observation time was 31,024 person-years. The incidence rate per 100,000 person-years was 29.01 for squamous cell carcinoma, 19.34 for basal cell carcinoma, 6.45 for malignant melanoma 3.22 for Kaposi sarcoma, and 74.17 for Bowen's disease and actinic keratosis. The incidence rate per 100,000 person-years was the highest in patients undergoing heart transplantation (610.50), followed by those who underwent kidney transplantation (136.54) and liver transplantation (90.15). Koreans showed lower incidence rates than those observed in Westerners. Conclusion: The incidence of primary skin cancer and precancerous lesions after solid organ transplantation in Koreans was lower than that in Westerners. Squamous cell carcinoma was the most common skin cancer in patients undergoing solid organ transplantation and the incidence rate of skin cancer and precancerous lesions was the highest in patients undergoing heart transplantation.
