This study was performed to evaluate the anti-inflammatory activities of 70% ethanol extract from Ambrosia trifida L. (AT). The electron donating ability and ABTS+ radical scavenging ability of extract from AT was shown to be 84.1% and 92.5% at 1,000 ㎍/ml concentration. The astringent effect of extract from AT was shown to be 94.7% at 1,000 ㎍/ml. The anti- inflammatory activities of extract of AT were investigated using RAW 264.7 cells induced by lipopolysaccharide (LPS). The cell toxicity effect of AT extract on RAW 264.7 performed MTT assay. As a result of the measured cell toxicity effect, 90% or more was shown with cell viability at a 500 ㎍/ml concentration. In nitric oxide synthesis inhibition effect, it was shown that extract from AT concentration dependent inhibited nitric oxide production. The protein expression inhibitory effect of AT extract was measured by western blot at 25, 50, and 100 ㎍/ml concentration and the β-actin used as a positive control. Consequently, the inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 protein expression inhibitory effect was decreased by 8.6%, 25.1% at 100 ㎍/ml concentration. The phosphorylation of extracellular signal-regulated kinase 1/2, p38, c-Jun NH2-terminal kinase and Iκ-Bα protein expression inhibitory effect was a decreased dependent concentration. The mRNA expression inhibitory effect was measured by reverse transcription - polymerase chain reaction at 25, 50, and 100 ㎍/ml concentration and the glyceraldehyde-3-phosphate dehydrogenase used as a positive control. Consequently, the iNOS, COX-2, interleukin (IL)-1β, IL-6 and tumor necrosis factor-α mRNA expression inhibition effect was a decreased dependent concentration in an LPS-activated macrophage. In conclusion, AT extract may have some effects on inflammatory factors as potential anti-inflammatory agents and natural substance for cosmetics.

Background: Recently 980-nm diode laser endovenous treatment was introduced and used as a method of treatment for varicose vein in lower extremities. The advantages of endovenous laser treatment are good cosmetic effects without incision and avoidance of complications associated with surgery. Therefore, we performed an endovenous laser treatment using a 980-nm diode laser and observed the effects and the efficiency of treatment. Material and Method: From October, 2003 to March, 2004, 55 patients (84 limbs) underwent endovenous laser treatment with a 980-nm diode laser. The effects of treatment, complications and recurrences were reviewed. Result The mean age of patients was 47.2 years old and the number of men and women were 2f and 35. In a total of 84 limbs, postoperative complications were transient ecchymosis(84 cases), local paresthesia (24 cases), local skin discolorization (6 cases), minimal burn (3 cases), and post operative phlebitis (1 cases). Adjuvant sclerotherapy was performed in 27 limbs and it was performed in varicose veins missed at operation and varicose veins remaining after endovenous laser treatment. In a total of 56 patients, 2 patients $(3.57\%)$ had recurrences after endovenous laser treatment and were treated with phlebectomy. Conclusion: Our findings demonstrated that 980-nm endovenous laser treatment had good cosmetic results with acceptable complications. This study was based on short-term results and long term follow-up is necessary to evaluate the accurate effects of treatment and recurrence. We think that multimodality treatment with endovenous laser treatment including phlebectomy or transilluminated powered phlebectomy can help decreasing of recurrence especially in patients with tortuous varicose cluster.

This study focuses on the differences in general self-concept, academic self-concept, significant others self-concept and emotional-physical self-concept in relation to appearance management behavior. It goes on to show that appearance management behaviors such as styles in clothing, makeup, skin care, hair care, cosmetic surgery and body shaping, weight control management are strongly influenced by self-concept. Therefore, this study was carried out with the aim of providing basic understanding and information on the appearance management behavior of middle school students. It was also done in an effort to find ways of improving the self-concept of students through education as a part of the domestic science curriculum. The results obtained in this study are as follows: On average, the middle school students who took part in this study showed low self-concept and appearance management behavior which indicates a negative image of themselves. This suggests that efforts need to be made so that students can see themselves in a positive way and improve their self-concept through appearance management behavior. Middle school students with a positive self-concept try to present themselves by keeping their skin clean and their hair attractive. They express their self-esteem and personality through fashion and by keeping and maintaining their clothing, shoes and bags. They also tend to show a positive attitude towards their studies and are more likely to understand and get along with others. The students who showed positive attitudes towards their bodies and emotions have a higher interest in clothing and try to express the image that they want for themselves. They are also less likely to change their bodies unnaturally through cosmetic surgery and body shaping. Appropriate appearance management behavior can help middle school students see themselves in a more positive way.
Purpose: To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. Materials and Methods: One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10~16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13~179 months, with a median of 92.5 months. Results: The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ($\leq$6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conclusion: Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.
The skin of human is constantly being exposed to environmental irritants such as ultraviolet, smoke and chemicals. These irritants cause free radicals and reactive oxygen species which leave serious damages on the cells of skin. The water and ethanol extracts of Cambodian Phellinus linteus were investigated for the activities of anti-lipid peroxidation and anti-wrinkle effects to apply as a functional ingredient for cosmetic products. As the result of evaluation of liquid oxidation rate by add $Fe^{2+}$ and $Cu^{2+}$ to Cambodian Phellinus linteus extracts, Cambodian Phellinus linteus ethanol extracts were higher than Cambodian Phellinus linteus water extracts in the chealting ability of $Fe^{2+}$ and $Cu^{2+}$. The Cambodian Phellinus linteus ethanol extracts exhibited that anti-lipid peroxidation higher than butylated hydroxytoluene (BHT) at the concentration of 0.1 mg/ml, 0.5 mg/ml and 1 mg/ml. Cambodian Phellinus linteus water and ethanol extracts showed a higher inhibitory effect on $Fe^{2+}$-induced lipid peroxidation compared to $Cu^{2+}$-induced lipid peroxidation. In the case of anti-wrinkle effect, the elastase inhibition activity of Cambodian Phellinus linteus ethanol extracts was 50.7%, and it is higher than urosolic acid at the concentration of 0.01 mg/ml. Also, in collagenase inhibition activity, Cambodian Phellinus linteus water extract showed low effect, but Cambodian Phellinus linteus ethanol extract was about 50% at a 0.1 mg/ml. concentration. These results proved that Cambodian Phellinus linteus had anti-lipid peroxidation and anti-wrinkle effect. Therefore, Cambodian Phellinus linteus could be useful as an anti-wrinkle cosmetic ingredient.

The phenolic compounds of walnut extracts by various solvents were shown to be 24.3 mg/g in hot water, 34.4 mg/g in ethanol, 32.5 mg/g in methanol and 15.1 mg/g in acetone. In a comparison of phenolic compounds from hot water and different concentrations of ethanol, which are harmless, 60% ethanol extract and hot water extract were 34.7 mg/g, 24.6 mg/g. The electron donating ability (EDA) of walnut extracts in hot water and 60% ethanol were 78.1% and 80.6%. According to ABTS radical cation decolorization for antioxidant activity, hot water and 60% ethanol extract showed high antioxidant activities of 98.1% and 98.3%. Antioxidant protection factor (PF) were $1.1{\pm}0.2$ PF and $1.1{\pm}0.4$ PF in hot water and 60% ethanol extract. In TBARs inhibitory activity, each extract showed high antioxidant activities at 60% and 75%. Anti-inflammation effects of walnut extract were tested, and inhibition of NO was 50% in 100 ${\mu}g/ml$ phenolics. Inhibitory activity against iNOS and COX-2 were shown, through Western blot, to be 10% in 100 ${\mu}g/ml$ phenolics. Tyrosine inhibitory activity of 60% ethanol extract was 43%, and astringent effect of 60% ethanol extract was 55%. These results suggest that walnut extracts are suitable for functional cosmetics requiring skin-whitening and anti-wrinkle activity.
Psoriasis is an autoimmune skin disease that is accompanied by hyper proliferation of the epidermis, erythema of various sizes, and ulceration. However, the mechanism of the development of psoriasis dermatitis is unclear. Recently, it is known that the inflammatory cytokines and Th17 cells as well as chemokine (CC motif) ligand 20 (CCL20) are involved in the process of keratinocytes hyper-differentiation, which is common in psoriasis dermatitis. Therefore, we studied the effects of yakuchinone-A, an active ingredient of Alpinia oxyphylla Miquel known for its anti-inflammatory activity, to improve psoriasis dermatitis. First, cytotoxicity of yakuchinone-A was observed in cell counting kit-8 assay and not observed in 10 ㎍/mL concentration on the human keratinocyte HaCaT cells. Yakuchinone-A in the presence of tumor necrosis factor-alpha (TNF-α) on HaCaT cells inhibited mRNA expression of IL-6, IL-8, and TNF-α by up to 61.4±7.5, 23.6±1.5, 46.0±4.8%. CCL20, a chemokine that attracts immune cells such Th17 cells to the inflammation location, was also significantly suppressed by yakuchinone-A. In addition, IκB and STAT3 phosphorylation involved in the CCL20 expression was inhibited by yakuchinone-A in a concentration-dependent manner up to the level of 79.1±5.0, 80.8±2.3%. Furthermore, yakuchinone-A downregulated CCL20 mRNA expression level on IL-17A-activated HaCaT cells as a concentration-dependent manner. Based on these results, yakuchinone-A is expected to be developed as a new material for improving psoriasis dermatitis in the future.

Background: In principle, cervical tuberculous lymphadenitis (CTBL) is a medical disease that may require surgical treatment, particularly in young women who complain of psychosocial and cosmetic problems. We encountered 13 cases of aggravated CTBL treated surgically despite the appropriate course of antituberculous chemotherapy. We report the clinical characteristis of these cases. Methods: The clinical data of 13 patients with aggravated CTBL requiring surgical treatment from January 2000 to December 2006 at the Department of Chest Medicine, Internal Medicine and Plastic Surgery, National Medical Center was reviewed retrospectively. Results: Twelve of the 13 cases (92%) were female. The most common age was 21~30 years (69%). Multiple nodes were palpated in 11 cases (85%). The supraclavicular lymph nodes were sites the most commonly involved (54%). The other involved sites in the order of decreasing frequency were the jugular chain, posterior cervical, submandibular and infraauricular lymph nodes. A palpable mass was the most commonsymptom. Neck pain was reported in 3 cases (23%). General symptoms such as weight loss, fatigue, anorexia and night sweats were noted in 5 cases (38%). Respiratory symptoms such as cough, sputum, hemoptysis, dyspnea and chest pain were observed in 4 cases (31%). Pulmonary tuberculosis was noted in 11 cases (85%). Other extrapulmonary tuberculosis coexisted in 4 cases (31%). This suggests that surgical CTBLs may be manifestations of a systemic disease and might be difficult to treat. Most cases (92%) were stages 2 and 3 at the initial diagnostic period but all cases fell into stage 4 and 5 when reassesed before surgery. The average duration of anti-TB chemotherapy before and after surgery was 10.2 and 15.2 months, respectively. The 13 patients were followed up until June. 2008. Among them, 2 cases had newly developed CTBL and the other 11cases showed no recurrence. Conclusion: In principle, CTBL is the medical disease. However, despite the appropriate course of anti-TB chemotherapy, CTBL can progress to a more advanced stages and grow rapidly to a large-sized or fistulous mass with a persistent abscess. Surgical treatment may be inevitable for patients with psychosocial and cosmetic problems caused by these masses, particularly in young women.

In this study, the cellular protective effect and antioxidative property of peanut sprout root extracts were investigated. Cellular protective effects of peanut sprout root extracts on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The ethyl acetate fraction of extracts exhibited a cellular protective effect in a concentration dependent manner. Particularly, the aglycone fraction of extracts showed prominent cellular protective effects in a concentration range (5~50 ${\mu}g/mL$). They are more effective than that of (+)-${\alpha}$-tocopherol, known as a lipid peroxidation chain blocker. Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of peanut sprout root extracts on ROS generated in $Fe^{3+}$-EDTA/$H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction of extracts ($OSC_{50}$; 1.59 ${\mu}g/mL$) showed a similar ROS scavenging activity compare with that of L-ascorbic acid (1.50 ${\mu}g/mL$), known as a strong antioxidant. On the other hand, the order of free radical (1,1-diphenyl-2-picrylhydraxyl, DPPH) scavenging activity ($FSC_{50}$) was (+)-${\alpha}$-tocopherol > 80% MeOH extract > aglycone fraction > ethyl acetate fraction. These results indicate that peanut sprout root extracts can function as an antioxidant in biological systems, particularly skin exposed to solar UV radiation by scavenging $^1O_2$ and other ROS, and to protect cellular membranes against ROS.

Acne vulgaris is a chronic inflammatory condition characterized by comedo, papule, cyst, nodule and postinflammatory hyperpigmentation. Meanwhile, it is also induced by adverse event of drugs. Among them, acneiform folliculitis is a side effect of epidermal growth factor receptor (EGFR) inhibitor, which is an anticancer agent, and its incidence may occur in upward of 75 ~ 100% of cases. The main method of acne vulgaris treatment is oral antibiotics, retinoids, topical medication and so on. However, it is limitation that teratogenicity caused by retinoids and antibiotic resistance increased by using antibiotics. In this study, we aimed to evaluate the clinical efficacy and safety of topical recombinant human (rh) EGF in treating facial acne vulgaris. Twenty three Koreans (age: 10 ~ 29 years) with mild to moderate acne vulgar participated in the study and applied topical rhEGF cream (trouble control EGF) with 3 products (trouble control clarifying cleansing foam, trouble control all-clear filling toner, redroll calming moisture) on their face twice daily for four weeks. Several assessment methods were applied: Acne lesion counts score by investigator's global assessment, efficacy and satisfaction score by subjects. Skin sebum output level, hydration level and redness level were also measured at each visit. At the final visit, skin sebum level, transepidermal water loss, skin redness statistically decreased and acne lesions (comedone, papule) were statistically reduced. No severe side effects were observed during the study. In conclusion, topical rhEGF seems to be an effective and safe adjuvant treatment option for mild acne vulgaris.
