The purpose of this study was to identify the effect of auriculotherapy on menstrual cramps, dysmenorrhea and skin resistance variability(SRV) of the female nursing students. This study was a pre-test and post-test with non-equivalent groups design. The subjects were 64 female university students experiencing dysmenorrhea in Cheonan and Gyeongju; 31 for the treatment group and 33 for the sham treatment group. The subjects of the treatment group received auriculotherapy twice a week for 5 weeks and sham treatment group received sham auriculotherapy using tape. The obtained data were analyzed by SPSS/WIN12.0 program. The menstrual cramps, negative emotions about the menstruation and skin resistance in the treatment group was significantly less than in the sham treatment group. However, there were no statistical differences in autonomic nervous system reactions. Based on these results, auriculotherapy could improve the quality of life for dysmenorrhea of female university students. However, further studies are necessary to support the effect of auriculotherapy and the scientific validity of skin resistance variability(SRV).

Chitinase-3-like-1 (CHI3L1) is known to induce inflammation in the progression of allergic diseases. Previous our studies revealed that 2-({3-[2-(1-cyclohexen-1-yl)ethyl]-6,7-dimethoxy-4-oxo-3,4-dihydro-2-quinazolinyl}sulfanyl)-N-(4-ethylphenyl)butanamide (K284-6111; K284), the CHI3L1 inhibiting compound, has the anti-inflammatory effect on neuroinflammation. In this study, we investigated that K284 treatment could inhibit the development of atopic dermatitis (AD). To identify the effect of K284, we used phthalic anhydride (5% PA)-induced AD animal model and in vitro reconstructed human skin model. We analyzed the expression of AD-related cytokine mediators and NF-κB signaling by Western blotting, ELISA and quantitative real-time PCR. Histological analysis showed that K284 treatment suppressed PA-induced epidermal thickening and infiltration of mast cells. K284 treatment also reduced PA-induced release of inflammatory cytokines. In addition, K284 treatment inhibited the expression of NF-κB activity in PA-treated skin tissues and TNF-α and IFN-γ-treated HaCaT cells. Protein-association network analysis indicated that CHI3L1 is associated with lactoferrin (LTF). LTF was elevated in PA-treated skin tissues and TNF-α and IFN-γ-induced HaCaT cells. However, this expression was reduced by K284 treatment. Knockdown of LTF decreased the expression of inflammatory cytokines in TNF-α and IFN-γ-induced HaCaT cells. Moreover, anti-LTF antibody treatment alleviated AD development in PA-induced AD model. Our data demonstrate that CHI3L1 targeting K284 reduces AD-like skin inflammation and K284 could be a promising therapeutic agent for AD by inhibition of LTF expression.

Wogonin(5,7-dihydroxy-8-methoxyflavone), an anti-inflammatory plant flavonoid, was previously demonstrated to modulate the several parameters of animal skin inflammation. This compound inhibited edematic response as well as proinflammatory gene expression. In this investigation, the histopathological changes of the lesions from different types of experimental skin inflammation were compared and the potential therapeutic effect of topically applied wogonin was evaluated. From the results, it was found that multiple TPA treatment drastically increased ear edema accompanied with epidermal hyperplasia and inflammatory cell infiltration, while phenol treatment provoked only edematic response in the dermal area. Wogonin somewhat differently inhibited these animal models of skin inflammation.

Background and Objectives The ultimate goal in current skin rejuvenation practice is to achieve a good result with minimal pain and downtime. Nonablative skin rejuvenation (NSR) is one technique. The efficacy of the long-pulsed 1064 nm Nd:YAG laser (LPNDY) has not been assessed in NSR. Materials and Methods Three target areas were selected (bilateral cheeks and glabellar region) in six volunteer subjects. A LPNDY with an integral skin temperature monitor delivered three stacked shots to each target area (1064 nm, 12 mm spot, 13 J/cm², 1 Hz) without any skin cooling or anesthesia. The skin temperature was recorded before, during, and after each set of shots using the system monitor and in real-time using a high-sensitivity (±0.001℃) near-infrared video camera. The skin reaction was observed with the naked eye, and pain and discomfort were assessed by the subjects during and after treatment. Results The subjects reported a mild feeling of heat with no discomfort during or after the test treatments. Mild erythema was observed around the treatment areas, without noticeable edema. A series of three ascending skin temperature stepwise peaks, with a decrease in skin temperature towards the baseline after the third shot, was observed consistently. The mean temperatures for shots 1, 2, and 3 for the cheeks were 39.5℃, 42.0℃, and 44.4℃, respectively, and for the glabella, 40.8℃, 43.9℃, and 46.2℃, respectively. Similar ranges were indicated on the system integral temperature monitor. Conclusion A set of three stacked pulses with the LPNDY at a low fluence achieved ideal dermal temperatures to achieve some dermal remodeling but without any downtime or adverse events. The temperature data from the integral thermal sensor matched the video camera measurements with practical accuracy for skin rejuvenation requirements. These data suggest that LPNDY would satisfy the necessary criteria to achieve effective NSR, but further studies will be needed to assess the actual results in clinical practice.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book(Dong-ui-bo-gam). Oriental herbs(Angelica daurica, Arctium lappa, Coptidis rhizoma, and Glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay; P. acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acnes. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation or $C^{14}$-acetate in culture media. The $C^{14}$-labeled lipids were extracted and determined by liquid scintilation counting. Coptidis rhizoma markedly inhibited sebum production. 3. Anti-bacterial assay for P. acnes(MIC test); Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis, Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica, Coptidis rhizoma. and Glycyrrhiza glabra is expected to provide effective acne treatment.

Psoriasis is an auto-immune skin disease, which is characterized by the excessive generation of plaques on the skin with typically a long-lasting red, itchy and scaly symptoms. Imiquimod, which has been used for the treatment of external genital warts, actinic keratosis, and superficial basal cell carcinoma, induced of psoriasis-like skin disorders with skin erythema and thickness in mice. In the present study, we tried to find the bioactive herbal extract against imiquimod-induced psoriasis-like skin disorder in mice. During the searching of the herbal extract with anti-psoriatic effect, the ethanolic extract of Cnidium officinale ameliorated imiquimod-induced psoriasis-like skin disorder in mice. The morphological evaluation, H&E staining and Psoriasis Area and Severity Index (PASI) score showed that ear and back thickness, and erythema induced by imiquimod were significantly reversed after the treatment of the cream of the ethanolic extract of C. officinale. The overexpressed myeloperoxidase (MPO) and keratin 6A levels were decreased by the treatment of C. officinale cream. Also, $IFN-{\gamma}$, c-fos and $I{\kappa}B-{\alpha}$ mRNA levels, which are related to the progression of psoriasis, were reduced by C. officinale cream. Thus, the ethanolic extract of C. officinale ameliorated psoriasis-like skin disorder induced by imiquimod and might be the therapeutic agent for psoriasis.

Objectives : Atopic dermatitis is a skin problem that causes dry skin, intense itching, and then a red, raised rash. It may be a long-lasting (chronic) skin problem that requires more than one treatment. The cause of atopic dermatitis isn't clear, but it affects the skin's ability to hold moisture. The skin becomes dry, itchy, and easily irritated. The purpose of this study was to report the clinical effects of herbal medicine on atopic dermatitis. Methods : We employed oriental medical treatments; herbal-medication (Cheonggisanbyeonbang), acupuncture, moxibustion and cupping therapy. At the same time, the patient sweated out the skin poison. We treated him two times a week with oriental therapy method. He took medicine three times a day after a meal. During taking medicine, we let him avoid fatty food, flour based food, and alcohol. We took a picture the patient's body parts and compared the symptom with previous symptom. With the picture, we evaluated the patient's condition. Results : After taking treatment - 17 times' acupuncture, moxibustion and cupping therapy during 4 months- and taking herbal-medicine, the skin condition of the patient was much improved. At first, he was troubled with itching and hot feeling at reddish area, time after time the itching and hot feeling was weakened. The reddish area was changed to dry condition and changed to normal state. In advance, the symptom of arms was improved, and later the symptom of legs was started to improve. Conclusion : Herbal medicine (Cheonggisanbyeonbang) was an effective in the treatment of atopic dermatitis and it helped to improve regenerating the skin in the body.

Increasing frequency of skin cancer, mycosis fungoides, Kaposi's sarcoma etc, it need to treatment dose planning for total skin electron beam (TSEB) therapy. Appropriate treatment planning for TSEB therapy is needed to give homogeneous dose distribution throughout the entire skin surface. The energy of 6 MeV electron from the 18 MeV medical linear accelerator was adapted for superficial total skin electron beam therapy. The energy of the electron beam was reduced to 4.2 MeV by a $0.5\;cm\times90\;cm{\times}180\;cm$ acryl screen placed in a feet front of the patient. Six dual field beam was adapted for total skin irradiation to encompass the entire body surface from head to toe simultaneously. The patients were treated behind the acryl screen plate acted as a beam scatterer and contained a parallel-plate shallow ion chamber for dosimetry and beam monitoring. During treatment, the patient was placed in six different positions due to be homogeneous dose distribution for whole skin around the body. One treatment session delivered 400 cGy to the entire skin surface and patients were treated twice a week for eight consecutive weeks, which is equivalent to TDF value 57. instrumentation and techniques developed in determining the depth dose, dose distribution and bremsstrahlung dose are discussed.

Rheumatoid arthritis is a long lasting autoimmune disorder that primarily affects joints, and patients with rheumatoid arthritis are predisposed to development of chronic skin ulcers. In addition, skin ulcers with rheumatoid arthritis tend to persist despite treatment because of sustained inflammation and poor healing capacity. Treatment of skin ulcers involves medications, wound coating agents, and surgical procedures including skin grafting, however, wound dressing or skin grafts are generally excluded because of excessive cost and time and poor intake rate. The dorsal metacarpal artery perforator (DMAP) flap, a vascular island flap for coverage of soft tissue defects on the fingers, provides promising results including matched quality and color. We experienced a case of DMAP flap for reconstruction of a rheumatoid ulcer, and a DMAP flap may be considered as a good faithful option for treatment of patients with rheumatoid ulcer.

The present study was conducted to determine whether skin spread of Myrrha and Tending Diancibo Pu (TDP) irradiation have a remarkable effect on the cell regeneration as well as wound healing following dermal scald burn injury. Burn injury was induced on dorsal surface $(TBSA\;15\~20\%)$ by scald burn in rats. Postburn concentration of serum protein was significantly decreased compared with sham-treated, double treatment with Myrrha and TDP was significantly increased the protein concentration compared with that of burn control. The content of keratinocyte growth factor (KGF) at 48 h is higher than that of at 24 h, and double treatment with Myrrha and TDP was the most effective to increase the production of KGF in all experimental groups. Morphologically, epithelial regeneration and dermal collagen synthesis by fibroblasts were accelerated in Myrrha and TDP treated group compared with bum control at same time postburn. At 48 h after burn, all dermal connective tissues are recovered to new collagen fibers in case of Myrrha and TDP double treated group. The data suggest that double treatment with skin spread of Myrrha and TDP radiation have a remarkable effect of to accelerate cell regeneration and wound healing in case of scald burn skin.
