The wrinkle is a typical sign showing aging. These days lots of people want to have a young and healthy appearance and many medical doctors are studying about wrinkle cure. In fact a young face without wrinkle looks more healthy and energetic. Therefore the wrinkle cure is important at the point of medical view. This research is an investigation of several studies about wrinkle cure using acupuncture needle. We have to consider the problem of the whole body which is related 12 meridians and meridian muscles as well as topical skin and tissues. There are three parts affecting wrinkle formation and cure. The first is a meridian and meridian muscle, the second is a local muscle and fascia on the head and neck, the third is a local skin structure. There are three kinds of method to cure the wrinkle locally. The first one is the perpendicular treatment of acupuncture, called the microneedle therapy, the process of this method is that lots of microneedles stab in the skin to dermis. The second one is the transverse treatment of acupuncture. The process of this method is that an acupuncture needle inserts just under the wrinkle skin. The third one is the incision treatment of acupuncture, called subcision, the process of this method is to cut the fibrous band which connect from the facial muscle to SMS(superficial musculoaponeurotic system) using cuttable needle. The hematoma after treatment let a collagen increase.

Background: Postherpetic neuralgia (PHN) is a serious complication resulting from herpes zoster infections, and it can impair the quality of life. In order to relieve pain from PHN, various treatments, including pharmacological and interventional methods have been used. However, little information on the recommendations for the interventional treatment of PHN, along with a lack of nation-wide surveys on the current status of PHN treatment exists. This multicenter study is the first survey on the treatment status of PHN in Korea. Methods: Retrospective chart reviews were conducted on the entire patients who visited the pain clinics of 11 teaching hospitals from January to December of 2011. Co-morbid disease, affected site of PHN, routes to pain clinic visits, parenteral/topical medications for treatment, drugs used for nerve block, types and frequency of nerve blocks were investigated. Results: A total of 1,414 patients' medical records were reviewed. The most commonly affected site was the thoracic area. The anticonvulsants and interlaminar epidural blocks were the most frequently used pharmacological and interventional methods for PHN treatment. For the interval of epidural block, intervals of 5 or more-weeks were the most popular. The proportion of PHN patients who get information from the mass media or the internet was only 0.8%.The incidence of suspected zoster sine herpete was only 0.1%. Conclusions: The treatment methods for PHN vary among hospitals. The establishment of treatment recommendation for PHN treatment is necessary. In addition, public relations activities are required in order to inform the patients of PHN treatments by pain clinicians.

External lyogels containing prostaglandin $E_1$ ethyl ester $(PGE_1-EE)$, a prodrug of prostaglandin $E_1\;(PGE_1)$ as a therapeutic agent for erectile dysfunction, were formulated to overcome the aqueous instability and enhance the percutaneous absorption. Lyogels of $PGE_1-EE$ were prepared with ethanol (EtOH)/proplyene glycol (PG) cosolvent system as a vehicle, cineol as an enhancer, and hydroxypropylcellusose as a gelling agent. In vitro percutaneous absorption studies were performed to determine the rate of $PGE_1$ absorption through rat or hairless mouse skin. The permeability of $PGE_1-EE$ lyogel with enhancer was 16-fold greater than that of lyogel without enhancer. Cosolvent produced 9-fold increase in percutaneous absorption. Pharmacodynamic effects of lyogels were evaluated in mature male cats in terms of intracavernosal pressure (ICP). Lyogels containing 0.1 % of $PGE_1-EE$ showed higher ICP compared to intraurethral preparation of $PGE_1$ (1 %) and enhancer-free control lyogel. The shelf-life $(t_{10%})$ of lyogel at refrigerated condition $(4^{\circ}C)$ was calculated as 928 days, which is 4.2 times longer than that of control hydrogel. As a result, $PGE_1-EE$ was formulated successfully to a lyogel system with a selective enhancer and cosolvent system for the topical delivery of $PGE_1$.

The objective of the present study was to establish the method of measurement of hydrogen peroxide and to estimate the anti-oxidative effect of genistein in the skin. UVB induced skin oxidation and anti-oxidative effect of genistein formulations were evaluated by determining levels of hydrogen peroxide. The mechanism involved in the determination of hydrogen peroxide is based on a color reaction between ferric ion ($Fe^{3+}$) and xylenol orange, often called FOX assay and subsequent monitoring of absorbance values of the reactant at 540 nm. The reaction was to some extent pH-dependent and detection sensitivity was greatest at pH 1.75. Genistein liposomal gel demonstrated better anti-oxidative effect with regard to lowering hydrogen peroxide levels elevated by UVB irradiation compared to genistein-suspended gel. A linear relationship has been observed between anti-oxidative effect of genistein and drug deposition in the skin tissue. Genistein liposomal gel resulting in the localization of the drug in the deeper skin led to improved anti-oxidative effect compared to genistein gel. The suggested method for evaluation of oxidation of the skin can be used as a tool to screen effective anti-oxidative agents and their delivery systems acting on the skin.

The purpose of this study is to investigate science consumers' perceptions of the National Science Museum and suggest effective management strategies for the museum. Research questions were established and the analyses were conducted to achieve the research goals. The collection and analysis of the data were conducted through a new approach to image analysis that combines qualitative and quantitative methods. First, the image of the concept of science was derived from science consumers (adults, undergraduate and graduate students) through a qualitative research method (group-interviewing), and then text analysis was conducted. Second, quantitative research was conducted through LDA (Latent Dirichlet Allocation)-based topical modeling of 63,987 words extracted from 12,920 titles of blog postings from one of the most heavily-trafficked portal sites in Korea. The results of this study indicate that the perception of science differs according to the characteristics of the respondents. Further, topic-modeling extracted 20 topics from the blog posting titles and the topics were condensed into seven factors. Detailed discussions and managerial implications are provided in the conclusion section.

Royal jelly composes of many components, especially protein. Protein is a major factor which cause allergy. We focused on water soluble royal jelly (WSRJ) that was removed allergy - inducing protein. 10-hyroxy-2-decenoic acid content of WSRJ is 2.42 g/100 g, which is double compared to that of lypophilized RJ. To further access WSRJ as a cosmetic ingredient and potential external treatment for topical use, we investigated its ability to inhibit tyrosinase activity and melanin biosynthesis on melanogenesis in B16F1 melanoma cells. We found that WSRJ increased the cell viability in B16F1 melanoma cell and WSRJ (1~10 mg/ml) inhibited melanin synthesis in with 10 nM ${\alpha}$-melanocyte-stimulating hormone (${\alpha}$-MSH) for 48 h. WSRJ inhibited direct tyrosinase activity, which decreased melanin synthesis in ${\alpha}$-MSH stimulated B16F1 melanoma cells. Thease findings suggest that WSRJ induces the down regulation of melanogenesis by inhibiting tyrosinase activation.

Essential oils (EOs) have gained a renewed interest in many disciplines such as plant disease control and medicine. This review discusses the components of ginger EOs, their mode of action, and their potential nanotechnology applications in controlling tropical plant diseases. Gas chromatography-mass spectroscopy (GC-MS), high-performance liquid chromatography, and headspace procedures are commonly used to detect and profile their chemical compositions EOs in ginger. The ginger EOs are composed of monoterpenes (transcaryophyllene, camphene, geranial, eucalyptol, and neral) and sesquiterpene hydrocarbons (α-zingiberene, ar-curcumene, β-bisabolene, and β-sesquiphellandrene). GC-MS analysis of the EOs revealed many compounds but few compounds were revealed using the headspace approach. The EOs have a wide range of activities against many phytopathogens. EOs mode of action affects both the pathogen cell's external envelope and internal structures. The problems associated with solubility and stability of EOs had prompted the use nanotechnology such as nanoemulsions. The use of nanoemulsion to increase efficiency and supply of EOs to control plant diseases control was discussed in this present paper. The findings of this review paper may accelerate the effective use of ginger EOs in controlling tropical plant diseases.

Fourteen Infants with congenital cardiac anomalies underwent primary surgical Intervention within the first 12 months of life. There were eight patients with ventricular septal defect, two with total anomalous pulmonary venous return [TAPVR], and the remainders with tetralogy of Fallot, transposition of great arteries [d-TGA], Taussing-Bing malformation, and coronary A-V fistula. The age of the patients ranged from 5 to 12 months, with a mean age of 9.9 months. The mean weight was 6.7 Kg [3.8 to 9.5 KS]. Congestive heart failure persisting despite intensive medical treatment was present In 8 patients [56%], and was the most common indication for operation. Early operation was necessary in 5 of these patients [35%], because of failure to thrive and recurrent pulmonary infection. In one patient with TOF, frequent hypoxic spell prompted the necessity for early operation. In cases of VSD, TAP. VR, TOF, and coronary A-V fistula, Intracardiac repair was done with conventional cardiopulmonary bypass, chemical cold cardioplegia, and topical myocardial cooling. Deep hypothermic circulatory arrest with surface induced cooling, followed by core cooling and core rewarming, was employed .for better exposure in the cases of d-TGA and Taussing-Bing malformation. The results were however, not satisfactory. The overall mortality was 28 per cent. There were no deaths in the eight patients with VSD. The one with coronary A-V fistula survived. The other 5 cases all expired either on the table or immediately after operation. The non-fatal post-operative complications included low cardiac output, respiratory insufficiency, bleeding, and temporary A-V block. The causes of death were prolonged circulatory arrest time in d-TGA, complete A-V block and low cardiac output in TOF and Taussing-Bing malformation and prolonged bypass time and Inadequate correction in TAPVR.
