Background: Patients suffering with pectus carinatum complain of cosmetic problems when they stand and this in spite of wearing cloths. The standard surgical treatment of pectus carinatum is resection of the deformed cartilages, but the wide operative scar, post-operative pain and complications related with such an operation can occur. Therefore, we have peformed compressive brace therapy as a non-operative treatment for pectus carinatum and we observed the effects and the efficiency of this treatment. Material and Method: From January, 2001 to December, 2006, 109 patients wore the compressive brace for all day. The degree of satisfaction was evaluated after $6\sim9$ months of wearing the compressive brace. The degree of satisfaction was evaluated by a score of from $1\sim4$. A score of 1 was assigned when the status was worse, 2 when it was the same, 3 when there was partial improvement and 4 when remarkable improvement was observed. The degree of satisfaction was assessed subjectively by the parent if the patient was a child younger than middle school age, and the patients older than middle school age assessed the score themselves. Result: The mean score of the overall degree of satisfaction was $3.93{\pm}0.33$. Recurrence of pectus carinatum after removal of compressive brace occurred in 6 patients (5.5%) of the total 109 patients. But 4 patients of the total 6 recurred patients stopped wearing of compressive brace against our advice. The 6 recurred patients were re-corrected by re-wearing the compressive brace within 3 months after they originally removed the compressive brace. The complications were discomfort with initially wearing the compressive brace, which occurred in all patients, skin rash due to the compressive brace for 76 patients (69.7%) and skin discolorization with excessive compression for f6 patients (5.5%). The skin rash and discolorization returned to normal within a few months after removal of the compressive brace. Conclusion: This study demonstrated that non-surgical treatment with using the compressive brace for patients with pectus carinatum was effective, and especially for children and teenagers. Non-surgical treatment with using a compressive brace would be helpful for the patients suffering with pectus carinatum and who dislike surgical operations because of their fear about general anesthesia and operation-related complications. Yet long-term follow up is necessary to accurately evaluate the effectiveness of this compressive brace and the recurrences after removal of the compressive brace.
Selenium was initially considered toxic to humans, but it was then discovered that selenium is essential for normal life processes. Selenium plays important roles in antioxidants. It is expected that chitosan microcapsules containing nano-selenium will be able to be used as a key material in bio-medical and cosmetic applications. The high concentration of chitosan derivatives guarantees increased antioxidative activity. Both inorganic and organic forms of selenium can be nutritional sources. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals. The objective of this experiment was to study the antioxidative activity of chitosan nano-selenium. Our experiments were divided into five groups, in the presence of various concentrations(0.1%, 0.3%, 0.5%, 0.7%, and 0.9%) of chitosan. We performed an assessment of the antioxidant properties and cytotoxicity of respective concentrations of chitosan nano-selenium. The antioxidant activity was examined by the free radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl(DPPH) assay. The cytotoxicity effect was measured by means of 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay. As a result, the electron donating abilities of 0.1%, 0.3%, 0.5%, 0.7%, and 0.9% of chitosan nano-selenium exhibited effective andioxidant scavenging activity at 12.5 ${\mu}g/m{\ell}$ against DPPH radicals. 0.3% chitosan nano-selenium did not show cytotoxicity on human keratinocytes. In general, the cytotoxicity of 0.1% and 0.9% chitosan nano-selenium showed the lowest effects. Though low cytotoxicity of 0.5% and 0.7% chitosan nano-selenium exhibited 29.67% and 38.4% against human keratinocytes on adding 100 ${\mu}g/m{\ell}$ and 50 ${\mu}g/m{\ell}$, respectively, cell vitality was recovered with 200 ${\mu}g/m{\ell}$. These findings support the notion that chitosan nano-selenium may be useful as a new active ingredient source for bioactive compounds.

Arthrospira platensis is one of the oldest algae in the world and has been reported to have anti-aging properties, including phycocyanin, tocopherol and beta-carotene. In this study, we tried to search protective activities against UVB-induced reactive oxygen species(ROS) of Arthrospira platensis under indoor cultivation ethanol extracts(ICAE) and outdoor cultivation ethanol extracts(OCAE). The anti-oxidative capacities were evaluated by DPPH radical scavenging activity and SOD-like activities at various concentrations(0.1, 0.5, $1mg/m{\ell}$) of ICAE and OCAE. Zebrafish embryos and HaCaT cells were exposed to UVB radiation and treated with various concentrations(0, 0.01, 0.05, 0.1, 0.5, $1mg/m{\ell}$) of ICAE and OCAE. ROS levels of zebrafish and HaCaT cells were generated by UVB radiation. ROS levels were detected using a fluorescent microscope after DCFH-DA staining. The DPPH radical scavenging activity of ascorbic acid was 73% and SOD-like activity was 86% in the positive control group. ICAE and OCAE at $1mg/m{\ell}$ concentration showed 43, 57% DPPH radical scavenging activity and 20, 19% SOD-like activity. Anti-oxidative of ICAE and OCAE had lower effects than the positive control ascorbic acid but significant results. ROS of UVB-induced zebrafish embryos and HaCaT cells were higher than negative control. ICAE and OCAE treated group decreased ROS concentration dependently than UVB-induced positive control group. These results suggest that Arthrospira platensis ethanol extract may have usability value as a cosmetic material for skin protection.

In this study, we report the results of a study on the clinical evaluation of wrinkle improvement by developing a method for liposome of high-purity Centella asiatica extract used in pharmaceuticals and cosmetics, and a cream using the same. In order to make Centellasome-10EX stabilizing centella asiatica extract in liposome lamella vesicle, it could be completed using 5% hydrogenated lecithin and 2% sucrose distearate. The appearance of Centellasome-10EX was a creamy form of low viscosity, the color was pale yellow, and the odor had the inherent odor of the raw material. The pH was about 6.12, the specific gravity was 1.09, and the acid value was about 0.35. The content of the main constituents of centella asiatica extract contained in the liposome vesicle contains 10,800 ppm of asiatic acid, 10,900 ppm of asiaticoside, 6,000 ppm of madecasic acid, and 1,600 ppm of madecassoside, and long-term storage. There was no discoloration even at the time, and it was found that the main component remained stable thermodynamically. To mechanistically analyze the structure of the liposome vesicle of Centellasome-10EX, as a result of observation with a transmission electron microscope (Cryo-TEM), the multilayer vesicles are formed and filled with moisture, and there are 10 to 60 multilayers around it. It was confirmed that the liposome lamella vesicle was formed. As a clinical trial (in-vivo) test, the moisturizing effect of centellasome cream after application for 5 weeks was 28.3%, which was significantly increased compared to placebo. The skin elasticity effect was 13.6%, which significantly increased the moisturizing power than the placebo. The effect of improving fine wrinkles around the eyes was improved by 23.52% compared to placebo cream. Through the results of this study, it was possible to study the formulation and manufacturing method for encapsulation and stabilization of the developed Centellasome-10EX in the liposome vesicle. It is expected that the results obtained through clinical research on the wrinkle improvement effect of the cream using this can be widely used to study skin science in the cosmetic industry and to develop high-quality cosmetics with high efficacy.

A mechanically pressed juice of Bokbunja (Rubus coreanus Miq.) extract was prepared using 70% ethanol solution. The extract was subjected to gamma-irradiation treatment (20 kGy) and investigated for its change of color and biological activities. Hunter $L^*$ values of the irradiated Bokbunja extract were increased in comparison with the non-irradiated extracts, and the $a^*\;and\;b^*$values decreased by the irradiation treatment. The content of the total phenolic compounds in the non-irradiated and irradiated extracts were 58.4 and 56.5 mg/g, respectively. The 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activities of non-irradiated and irradiated extracts at a 250 ppm level were 80% and 79%, respectively. Lipid oxidation was retarded by addition of Bokbunja powder. Nitrite scavenging activity was the highest in the Bokbunja powder at pH 1.2 and the effect was not changed by irradiation. The Bokbunja powder showed antimicrobial activity against Salmonella Typhimurium and Bacillus cereus. However, irradiation of Bokbunja did not affect any physiological functions (p>0.05). A Salmonella mutagenicity assay indicated that the irradiated Bokbunja extract did not show any mutagenicity. Therefore, Bokbunja extract could be used in various applications as a functional material, such as ingredients of food and cosmetic, compositions with functions.
Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.
This study was conducted to determine the antioxidant, nitrite scavenging, melanin tyrosinase inhibitory, and melanogenesis inhibitory activities of fermented Coix lacryma-jobi L. var. mayuen Stapf. by Hericium erinaceum (Bull.: Fr.) mycelial hot water extract (FCLHE). Additionally, we analyzed β-glucan and ergosterol contents in FCLHE and C. lacryma-jobi hot water extract (CLHE). The ergosterol and β-glucan contents in FCLHE were 740.2 mg% and 245.3 mg%, respectively, whereas these components were not detected in CLHE. FCLHE showed higher cell viability than CLHE. When B16F10 cells were treated with 500 ㎍/mL each of CLHE and FCLHE, the FCLHE treated cells produced 8.9 uM nitric oxide (NO), which was lower than that produced by CLHE treated cells (10.6 uM). The FCLHE treated cells showed significantly greater tyrosinase inhibition and melanin production at all tested concentrations than when compared to the CLHE treated group. Antioxidant parameters such as DPPH and ABTS radical scavenging activities were higher in FCLHE than in CLHE. These results suggest that FCLHE can be used as a raw material for functional foods, for food additives, and in the cosmetic industry.
For many years, 10mm videothoracoscope has been widely used in bullectomy of primary spontaneous pneumothorax. However we used a 2mm videothoracoscope to minimize operative wound. Thus, we compared the clinical results of bulllectomy using 2mm videothoracoscope with bullectomy using 10mm videothoracoscope. Material and method: We analyzed 118 patients who underwent VATS for primary spontaneous pneumothorax from April, 1998 to December, 2000. 2mm videothoracoscope was used in 53 patients(Group A) and 10mm videothoracoscope was used in 65 patients(Group B). The mean age was 20.2$\pm$6.9 years old in group A and 20.1$\pm$6.1 years old in group B. The mean follow up was 10.9$\pm$3.8 months in group A and 11.4$\pm$4.3 months in group B. Result: The operation time was shorter in group A than group B(55.7$\pm$22.9 minutes, 71.2$\pm$21.4 minutes, p<0.05). The duration of postoperative hospital stay was shorter in group A than group B(7.2$\pm$3.2 days, 9.2$\pm$3.6 days, p<0.05). The duration of postoperative chest tube indwelling was shorter in group A than group B(4.7$\pm$3.1 days, 6.3$\pm$2.8 days, p<0.05). The duration of postoperative air leakage(0.6$\pm$2.1 days, 1.0$\pm$2.4 days, p>0.05), the amount of analgesics(1.38$\pm$1.0 ampules, 1.7$\pm$1.4 ampules, p>0.05), the amount of analgesics(1.38$\pm$1.0 ampules, 1.7$\pm$1.4 ampules, p>0.05), postperative complications(2 cases, 7cases, p>0.05) and recurrences(1 case, 1 case, p>0.05) were not statistically different between two groups. Operative wound was smaller in group A than B. Conclusion: There were non adverse results in group A than group B. Furthermore, bullectomy using 2mm videothoracoscope brought us minimized operative wound and good cosmetic results. Thus, we could recommend bullectomy using 2mm videothoracoscope in primary spontaneous penumothorax.

In this study, we investigated the anti-oxidant activities [electron-donating ability (EDA), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging ability, and reactive oxygen species (ROS) inhibitory activity], anti-wrinkle activities [collagenase inhibitory activity, suppression and/or phosphorylation of matrix metalloproteinases (MMPs), and mitogen-activated protein (MAP) kinase activity], and mRNA expression levels using reverse transcription-polymerase chain reaction (RT-PCR) assay in ultraviolet (UV) B ray ($50mJ/cm^2$)-irradiated human keratinocyte HaCaT cells. Josaengheugchal, Sinneungheugchal (SE), Shintoheug rice, Heugjinju rice, and Heugseol (HE) among colored rice varieties were reported to have excellent antioxidant properties. In the EDA and ABTS radical scavenging assays, extracts of the five colored rice varieties had scavenging activities of 72% at concentrations higher $50{\mu}g/mL$. In the collagenase inhibition assay, ethanol extracts of the five colored rice varieties showed high inhibitory effects of about 60% at concentrations higher $25{\mu}g/mL$. In the ROS inhibition assay, ethanol extracts of HE and SE showed very excellent inhibition efficacies at all concentrations. We determined molecular biological mechanisms of MMPs (MMP-1, -3, -8, and -13) and mitogen-activated protein kinase (MAPK) with HE, and the results show that HE suppressed expression of MMPs and phosphorylation of MAPK and increased expression of pro-collagen type I in UVB-irradiated cells. It was also confirmed by RT-PCR that HE reduced expression of MMPs mRNA. Therefore, these results suggest that HE has anti-wrinkle and collagen production effects and may be used as a material in the development of functional food and cosmetic industries.
