Atopic dermatitis induced NC/Nga mice were used to investigate the efficacy of HYT on the recovery of dermatitic symptoms by how HYT influenced the immune related factors. The results are as below: 1. Compared to the control, HYT treated group showed recovery of atopic dermatitis by the naked eye observation, and significant reduction of dermatits index was observed after 14 weeks. 2. HYT treated group showed significant decrease of the ratio of CCR3+, B220+/IgE+, and Gr-1+/CD11b+ immune cells in dorsal skin by 40.5%, 34.2%, and 48.1%, respectively. 3. HYT treated group showed increase in the ratio of CD19+ immune cells within PBMC by 10.8%, as well as decrease in CD3+, CD3+/CD69+, NKT+ ratios by 5.3%, 35.2%, and 44.9%, respectively. 4. HYT treated group showed increase in the expression of IFN-$\gamma$ in serum by 589.3%, whereas the expression of IL-4, IL-5, IL-6, IL-13, TNF-$\alpha$, MCP-1 and RANTES were decreased by 31.4%, 82.1%, 97.1%, 39.5%, 83.7%, 26.1%, 48.6%, respectively. A 47.2% decrease in IgE expression was also observed. The results above strongly supported the improvement of atopic dermatitis by HYT treatment through immune modulation. Further studies on the synergistic effect of each ingredients of HYT and therapeutic effects according to the dosage of each ingredient should be followed for clinical applications. This work was (partly) supported by the RIC program of MKE(Ministry of Knowledge Economy) in Daejeon University.

Pyomysitis is a primary acute bacterial infection of large skeletal muscule, usually occuring in the absence of specific cause of infection. Pyomyositis has been reported mainly in tropical countries and was rare in temperate climates. but it has been recognized with increasing frequency. Toxic shock syndrome(TSS) is an acute mutisystemic disease characterized by high fever, hypotension, multisystem dysfunction and erythematous rash followed by skin desquamation 8-12 days after onset. Especially, TSS and pyomyositis are rare conditions in the pediatric population. We experienced one case in a healthy 13-year-girl who developed pyomyositis of the right ileac and gluteal muscles associated with TSS caused by methicillin resistant Staphylococcus aureus. We reports a case of acute pyomyositis with TSS, in which the diagnosis was difficult because of the relative rare incidence in temperate climates and its vague symptoms. To our knowledge, this is the first reported case of pyomyositis with TSS in Korean pediatric population.

Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis that can affect multiple organs predominantly the skin, joints, gastrointestinal tract and kidney. Although the specific pathogenesis of HSP is not known, there are several hypotheses. Although the importance of the complement activation in glomerular injury in HSP has been suggested, the complement levels and the blood pressure in those patients are usually normal and massive proteinuria is not common. And pathologic renal changes also have been reported to show a large variety of glomerular changes. However, to our knowledge, a membranoproliferative glomerulo-nephritis (MPGN) is a rare renal clinicopathologic manifestation of HSP. We report a 6-year-old boy with HSP who developed MPGN with hypertension, massive proteinuria, and hypo-complementemia revealed activation of the classical complement pathway, although we could not exclude the possibility of other hypocomplementemic glomerulonephritis including post-streptococcal acute glomerulonephritis.

Background: Little is known about the news coverage of cancer risk factors in Korea. This study aimed to examine how the news media encompasses a wide array of content regarding cancer risk factors and related cancer sites, and investigate whether news coverage of cancer risk factors is congruent with the actual prevalence of the disease. Materials and Methods: A content analysis was conducted on 1,138 news stories covered during a 5-year period between 2008 and 2012. The news stories were selected from nationally representative media in Korea. Information was collected about cancer risk factors and cancer sites. Results: Of various cancer risk factors, occupational and environmental exposures appeared most frequently in the news. Breast cancer was mentioned the most in relation to cancer sites. Breast, cervical, prostate, and skin cancer were overrepresented in the media in comparison to incidence and mortality cases, whereas lung, thyroid, liver, and stomach cancer were underrepresented. Conclusions: To our knowledge, this research is the first investigation dealing with news coverage about cancer risk factors in Korea. The study findings show occupational and environmental exposures are emphasized more than personal lifestyle factors; further, more prevalent cancers in developed countries have greater media coverage, not reflecting the realities of the disease. The findings may help health journalists and other health storytellers to develop effective ways to communicate cancer risk factors.

Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a $4cm\times2.5cm$ growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier. The nodule was diagnosed as 3 different types of tumors: trichilemmoma, desmoplastic trichilemmoma, and basal cell carcinoma. To our knowledge, this is the first report of the coexistence of three different tumors arising from nevus sebaceous. It contain malignant neoplasm also. Surgeons should be aware of the need for close monitoring and early complete surgical excision of sebaceous nevus in order to improve patient outcomes.

This study aims at applying Photoshop functions to digital make-up(DM) for aging effect based upon the knowledge of phrenology, comparing the result with that of the real or off-line make-up(OM) and identifying any possible difference between two methods: which contributes to understanding the potential and problems of DM at application level. This study aims at suggesting a method to apply computer graphics(CGs) to special effect make-up for aging effect through a case, contributing to attracting academic concerns and building theoretical frameworks for DM. It used 'Aging Process' in Adobe Photoshop CS4 Extended(CS4E) to change a young girl into a senior lady. In the process of DM, the study applies various tools and methods to making face wrinkled, finds the most effective way among them for each area of face, suggests a method to integrate the ways and shows the result of the method. Compared with OM, DM using CS4E is the less constrained work regarding procedure and time. Specifically, it can save the time tremendously because the reiterative operation of work can be omitted, when the same work is repeated, using 'Action' function which memorizes the history of the work. Once a DM work is produced, since it is durable, reusable and convertible to various images with additional operations, it seems very economical as well as highly promising to market the work through on-line sales. Regarding face features and skin, it reviewed literature in make-up and phrenology while it used Photoshop CS4 Extended tools to demonstrate a case of aging effect by combining and painting pictures of a young lady and a senior citizen.

A 12-year-old spayed female mixed-bred dog presented with nasal bleeding of 2 days duration and a skin nodule in the left flank. No abnormalities were found in coagulation profiles and blood pressure. Cytological evaluation of the nodule revealed numerous characteristic round organisms having a nucleus and a bar within macrophages and in the background, consistent with leishmaniasis. In vitro culture was unsuccessful but PCR of the nodular aspirate identified the organisms as Leishmania infantum, and the final diagnosis was canine leishmaniasis. No history of travel to endemic countries was noted. Because the dog had received a blood transfusion 2 years before the illness, serological screening tests were performed in all donor dogs of the commercial blood bank using the commercial Leishmania ELISA test kit, and there were no positive results. Additional 113 dogs with hyperglobulinemia from Seoul were also screened with the same kits but no positive results were obtained. To the best of the author's knowledge this is the first autochthonous case of canine leishmaniasis in Korea.

Quantum Dot (QD) nanoparticles are used in various industrial applications, such as diagnostic, drug delivery, and imaging agents of biomedicine. Although QDs are extensively used in many medical science, several studies have been demonstrated the potential toxicity of nanoparticles. The first objective of this study was to investigate the nanotoxicity of QDs in the HaCaT human keratinocyte cell line by focusing on gene expression pattern. In order to evaluate the effect of QDs on gene expression profile in HaCaT cells, we analyzed the differential genes which related to oxidative stress and antioxidant defense mechanisms by using human cDNA microarray and PCR array. A human cDNA microarray was clone set, which was sorted for a list of genes correlated with cell mechanisms. We tried to confirm results of cDNA microarray by using PCR array, which is pathway-focused gene expression profiling technology using Real-Time PCR. Although we could not find the exactly same genes in both methods, we have screened the effects of QDs on global gene expression profiles in human skin cells. In addition, our results show that QD treatment somehow regulates cellular pathways of oxidative stress and antioxidant defense mechanisms. Therefore, we suggest that this study can enlarge our knowledge of the transcriptional profile and identify new candidate biomarker genes to evaluate the toxicity of nanotoxicology.

Purpose: An extensive knowledge of the arterial anatomy of the upper extremity and its variations is indispensable to the hand surgeon. We report a patient with anomalous radial artery, superficial course of two radial arteries, encountered during the excision of volar wrist ganglion. Methods: The patient was a 53-year-old man who had a painful mass on the left volar wrist for 1 year. Under general anesthesia, a curved incision was made around the mass. With the skin flaps retracted, the dome of the cyst was identified. Particular care was taken to identify and protect the radial artery, which was intimately attached to the wall of the ganglion. Two radial arteries completely encircled the ganglion. The pedicle was traced to the volar joint capsule, radiocarpal ligament. The joint was open and the capsular attachments were excised. Results: The patient made an uneventful recovery. There were two arterial pulsations at the volar side of the wrist joint. Compressing this site revealed that the major arterial contributor to blood supply in the hand was the ulnar artery. At angioCT, an anomaly of the radial artery was found with a duplication. The pathway of this aberrant artery was superficial to the original radial artery. It changed its course subcutaneously at the level of the tendon of the brachioradialis muscle, and crossing the wrist lateral to the original radial artery and ending in the deep palmar arch. Conclusion: Authors experienced a case of bifurcating radial artery encountered during the excision of ganglion on the volar of the wrist. Because these duplicated radial arteries make strong contributions to the thumb and index finger as well as to the deep palmar arch, when they are present there may be probably less blood supply to the hand from the ulnar artery. If the radial artery is palpated superficially on the brachioradialis muscle, it is important to remember the kind of anomaly.
