In the present study, we evaluated the free radical scavenging and xanthine oxidase inhibitory activities exhibited by extracts obtained from the dried stems (and leaves) of Lespedeza bicolor We also assessed its potential irritation activities with regard to cosmetic use. When the DPPH radical scavenging activities of L. bicolor were assessed at six different concentrations (0, 50, 100, 250, 500 and 1000 ${\mu}g/ml$), the concentration of L. bicolor required to inhibit DPPH radical formation by $50\%$ was found to be $164.90{\mu}g/ml$. The effects of L. bicolor on the inhibition of xanthine oxidase were determined at seven different concentrations. The $50\%$ effective concentration was found to be $282.75{\mu}g/ml$. In the skin irritation test, all animals survived for the duration of the study, and all exhibited normal gains in body weight. The control sites exhibited no response to the control procedures. No edema, erythema, or eschar formation was observed in any of the tested rabbits. In the ocular irritation study, all of the rabbit eyes remained normal. In summary, L. bicolor extracts were considered to be non-irritating to the skin and eye.

To investigate the alleviative effects of jujube water extract (JWE) on the inflammation and skin barrier damage, both the irradiation of UVB and the application of squalene monohydroperoxide (Sq-OOH) were applied to the back skin of experimental animals for 4 weeks. And at the same time experimental materials were applied topically. Six weeks female SKH-1 hairless mice were divided into five groups (five animals for each group) including normal (N; saline), control (C; UVB+Sq-OOH+saline), vehicle control (VC; UVB+Sq-OOH+vehicle), positive control (PC; UVB+Sq-OOH+0.01% retinoic acid) and experimental (E; UVB+Sq-OOH+JWE) groups. The skin erythema index in the E group was significantly low compared to the C group (p<0.05). Lipid (p<0.05) and water (p<0.01) capacities in the E group were significantly high compared to the C group. In comparison with the C group, E group showed a relatively well preserved lipid lamellae in the epidermis and a relatively much less infiltration of mast cells in the dermis or hypodermis. As for the both absolute and relative weights of the spleen, PC group were significantly higher than the other groups. These results suggest that JWE have a considerably inhibitory effect on the inflammation and the skin barrier damage induced by UVB irradiation and Sq-OOH application.

Objectives : Atopic dermatitis(AD) assume an remarkable clinical aspect and it s diagnosis almost depends on clinical symptoms. Therefore, we aimed to study the clinical diagnostic standard of AD for more accurate treatment. We repert as follows; Methods : For 6 months from March to August in 2000 we selected fifty outpatients who were prognosis of AD in the department of dermatology, Oriental medical hospitol, Dong-eui University. Results and Conclusions : 1. We classified of the grade, the condition of AD patient was slight and severe, by the sum of total by the clinical index of AD (diagnostic features). 2. By consulting previous oriental medical theories, we divided symptom-complex of AD into two type ; one was damp-heat type and the other was deficiency of blood- wind-dryness type. 3. Male to female ratio was 17 : 33 and the third stage, more than half of the patients were adolescents. 4. According to the results of symptom-complex of AD patients, on the first examination damp-heat type was more than deficiency of blood-wind-dryness type and in progressing treatment, the condition has been change to deficiency of blood-wind-dryness type. 5. In the lesions of AD, arm and knee were most serious skin lesions and in symptoms of AD, pruritus was most complained, and in progressing treatment, erosion and erythema were greatly improved. 6. When we measured the levels of serum Total IgE, that of thirty eight patientswere higher than that of normal, but elevation of serum IgE levels was not correlated with the severity of AD.

Tea flavonoids and polyphenols are well known for their extraordinary antioxidant activity which is considered important for anti-aging processes in animals. This study evaluated the anti-wrinkle effects of three different kinds of tea (Camellia sinensis) water extracts (CSWEs) including green, white, and black teas using a photoaged hairless mouse model. Data showed that the CSWE-treatment greatly improved skin conditions of mice suffering from UVB-induced photoaging, based on the parameters including the skin erythema index, moisture capacity, and transepidermal water loss. In addition, the wrinkle measurement and image analysis of skin replicas indicated that CSWEs remarkably inhibited wrinkle formation. In histological examination, the CSWE-treated mice exhibited diminished epidermal thickness and increased collagen and elastic fiber content, key signatures for skin restoration. Furthermore, the reduced expression of MMP-3, a collagen-degradative enzyme, was observed in the skin of CSWE-treated animals. Interestingly, comparative data between green, white, and black tea indicated that the anti-wrinkle activity of white tea and black tea is equally greater than that of green tea. Taken together, these data clearly demonstrated that CSWEs could be used as an effective anti-wrinkle agent in photoaged animal skin, implying their extended uses in therapeutics.

Objectives : The aim of this study is to review the effect of acupuncture/moxibustion on vitiligo. Methods : Using 5 databases(Pubmed, EMBASE, Cochrane Library, RISS, OASIS) clinical studies about effect of acupuncture/moxibustion on vitiligo were searched. Only randomized controlled trials(RCTs) were selected to analyze. Results : Total 235 studies were searched. After screening those studies 5 studies were selected from china and Iran. 3 studies used effective rate to measure the effect of acupuncture for vitiligo. 1 study used Vitiligo Area Scoring Index(VASI) and 1 study assessed 4 grade of repigmentation to prove acupuncture's effect on vitiligo. All studies showed repigmentation in acupuncture/moxibustion group. Adverse effects reported in the five studies were temporary erythema, itching, and dryness. Conclusions : These findings suggest that acupuncture and moxibustion can be considered a safe treatment for vitiligo. However, due to the small number of RCTs conducted on acupuncture and moxibustion for vitiligo, more RCTs should be conducted to confirm the effectiveness of acupuncture and moxibustion for vitiligo.

Objective : An adequate measurement for Atopic Dermatitis(AD) is essential for studies about the treatment of AD. To establish a new and adequate scoring system for AD in Korean medicine, we reviewed existing studies on AD outcome measurement in Korean medicine. Method : We searched for reviews on measurements of AD or studies which used an AD outcome measurement at the Korean Traditional Knowledge Portal from 1995 to June, 2008. And then we reviewed the pattern identification in AD patients and the outcome measurements for AD in each study. Results : 1. Among 25 studies, the most common measurement for AD was SCORAD(the severity SCORing of Atopic Dermatitis index), there were 16 studies. There was one study which used the Jakob T scoring system, one study which used ADSI(the Atopic Dermatitis Severity Index), and there were 7 studies which established or used a new severity scoring system for AD. 2. In Korean medicine, AD caused by Damp-Heat is accompanied by erythema, papulation, oozing and crust, Damp-Heat accompanied by Spleen-Gi deficiency is frequently found in pediatric patients, and in adults who have indigestion. Symptoms of AD caused by blood deficiency and Wind-Dryness include lichenification, dryness, scale and pigmentation. AD caused by toxic Heat in the blood system has symptoms similar to some Damp-Heat pattern along with symptoms of blood deficiency and Wind-Dryness. Conclusion : We need to establish a new severity scoring system which reflects pattern identifications and treatments with Korean medicine, and we should assess the validity, reliability, and sensitivity of the new scoring system.

Objectives: Pityriasis rubra pilaris (PRP) is a rare papulosquamous disorder with unknown etiology. Studies on adults have not been conducted yet in Korean medicine. We report the progress of Korean medicine treatment for adult-type pityriasis rubra pilaris. Methods: A 62-year-old female patient was diagnosed with PRP in June 2019. After the diagnosis of PRP, retinoid treatment was continued for about 6 months, and then the drug was switched to an oral immunosuppressant. However, the patient's symptoms did not improve, but instead worsened. The patient was treated with Mihudeungsikjang-tang and acupuncture therapy. We evaluated her treatment progress based on the Dermatology Life Quality Index (DLQI), a visual analogue scale (VAS), and the changes in the patient's subjective symptoms. Results: After Korean medicine treatment, the DLQI and VAS scores improved from 18 points to 16 points and from 6 points to 4 points, respectively. The whole-body itching and scaling were reduced by 30% compared to pretreatment. The itching and pain in the neck, which had been severely symptomatic, decreased by 50%. The pain and dysesthesia in the upper and lower extremities disappeared, but the erythema still remained. Conclusions: Conventional treatments for PRP have limitations due to adverse effects and difficulty in treating refractory forms. Korean medicine treatment is worth considering as it can complement the limitations of conventional treatments, although more studies will be needed.

Objectives : The aim of this study is to develop the system and evaluate the optical analytical technique that reflects acupoint pigmentation and extravasated blood by cupping. Methods : We designed the system able to express XYZ coordinate on local skin color. To evaluate measurement-accuracy, we compared with 24 Color Checker Chart by standardized Commission Internationale de l'Eclairage. After confirming the performance of system, we experimented with cupping which was 80 kPa negative pressure for 1 minute on left/right BL13. The X, Y and Z values were converted to R, G and B, $L^*$, $a^*$ and $b^*$, Erythema Index (E.I.), and Melanin Index (M.I). We compared and analyzed two cases on before/after cupping. Results : The R, G and B values which were converted by X, Y and Z values had high linearity as a high level of R-square (R: 0.969, G: 0.996, and B: 0.992). Moreover, we confirmed that it was possible to quantitatively analyzed the change in skin color by cupping using R, G, B, $L^*$, $a^*$, $b^*$, E.I., and M.I. Conclusions : Therefore, we proposed the new analytical technique for objectifying the oriental medical diagnostic method using cupping and optical sensing technique.
