  • Objective: To investigate the incidence of malignant transformation and P53 and P16 expression in teratomatous skin of ovarian mature cystic teratoma. Materials and Methods: Data on ovarian teratoma specimens in nearly 10 years were reviewed. P53 and P16 expression were detected by immunohistochemistry in 25 cases of teratomatous skin of ovarian mature cystic teratoma, 20 cases of squamous cell carcinoma and 2 cases of squamous cell carcinoma originated from teratomatous skin. Results: Of 1913 cases of ovarian mature cystic teratoma in nearly 10 years, only two cases of squamous cell carcinoma were found in teratomatous skin, with malignant transformation rate of 0.1045%. P53 expression was detected in 2 cases squamous cell carcinoma originated from teratomatous skin and P16 overexpression in one. There were no expressions of P53 and P16 in 25 cases of teratomatous skin of ovarian mature cystic teratoma. Of 20 cases of squamous cell carcinoma P53 overexpression (positive rate of 55%) was detected in 11 cases, P16 overexpression (positive rate of 35%) in 7 cases. The positive rates of P53 and P16 expression in squamous cell carcinomas were significantly higher than that in the teratomatous skins (p< 0.001, p= 0.002). Conclusions: There was low risk of malignant transformation in teratomatous skin of ovarian mature cystic teratoma which can be explained by lower P53 and P16 expressionin teratomas than that in squamous cell carcinoma.

  • In order to establish the diagnostic indices of skin diseases, some physiological and pathological concepts of interstices(腠理) were researched based on , and western dermatology with etymological analysis. As physiological indices for diagnosis of skin diseases, measurement of epidermis and dermis using ultrasonogram in the zhongwan and dachui's location. And for grading looseness and fineness of interstices with 3 unsound groups, measuring numbers and sizes of sweat pores in each point's 1 cm diameter circular area using comparative method and palpation assessment. Another index is superficial temperature. As pathological indices for diagnosis, validating volumes of dead skin cells and grading degrees of atrophy and degeneration of skin lesion. And as supplementary measures, absorptive degrees of cosmetics on face should be recorded according to 3 grades. These diagnostic indices can contribute to establishment of standard pattern identification and prescription of skin diseases through converting anatomical cognizance into classical concepts of interstices objectively.

  • The skin(皮膚) separates epidermis(皮) and dermis(膚) in Oriental medicine. epidermis and hair come from ectoderm as dermis comes from mesoderm in embryology. Epidermis and hair belong to the Metal(金) and dermis belongs to the Earth(土) in Oriental medicine. The lung is related to the skin and hair. The skin surface is nourished by the essence from the lung, and the. lung has the function of sending wei-qi(衛氣.: defensive Energy) to the skin surface to guarantee body resistance. The skin takes nourishment from blood(血) and express by qi(氣). The supply of nutrients to the lung and skin relies on the function of the spleen, pancreas and subcutis. Flaming of the heart fire may scorch the essence of the lung-metal, inducing dermatosis.

  • We reviewed 93 cases of fine needle aspiration of skin/subcutaneous and soft tissue lesions with histologic confirmation. On the basis of the most prominent cytologic features, morphologic classification of the aspirates was done. Skin and subcutaneous lesions included endometriosis, epidermal inclusion cyst, fat necrosis, pilomatrixoma and nodular fasciitis. Neoplastic lesions of soft tissue were categorized as ; round cell, spindle cell, polygonal cell, well-differentiated and myxoid tumor. This classification is convenient to recognize and categorize most soft tissue tumors.

  • Jaeum-Dan was reported new anti-aging effect formula previously. We investigated the physiological effects on human skin with Jaeum-Dan essence (JED). We made a skin application product as essence form contained oriental herbs, and measured various physiological effects such as skin moisture contents, red blood cell flow rates, skin surface temperature, corneocyte exfoliation and skin intensity when volunteers(female, n=40) used the application product for 4 weeks. The results were as follows: The skin moisture contents were not only increased in human face skin through using the product, but also red blood cell flow :rates in face skin were increased. After using the essence, the face skin temperature rose and corneocyte exfoliation was decreased. Furthermore the upper dermis intensity of skin in female face was subsequently increased 4 weeks later. The results indicate that the application product containing JED was improved the physiological effects of human facial skin..

  • The development of skin metastasis is usually a morbid prognostic feature although they occur infrequently. Adenocarcinomas account for up to about 70% of all metastatic skin cancer. In general, adenocarcinomas are the most difficult metastatic tumor to accurately identify the primary site because they don't have distinctive histological features. For this reason, immunohistochemistry have been used to help identify the origin of metastatic adenocarcinomas. This study performed immunohistochemical staining with metastatic adenocarcinomas of the skin using a variety of antisera to find out characteristic immunohistochemical findings of them. This study was made upon the 29 cases of metastatic adenocarcinomas of the skin, which had been confirmed histopathologically in Chonbuk National University Hospital from January, 1986 to April, 2006, Paraffin blocks were colledted and homemade tissue arrays were made. We performed immunohistochemical staning using 12 antibodies (MUC1, 2, 5AC, 6, cytokeratin (CK) 7, 20, thyroid transcription factor-1 (TTF-1), estrogen receptor (ER), progesterone receptor (PR), beta-catenin, cox-2, claudin-1). The mean age at the time of diagnosis was 60.7 years and the male to female ratio was 1.2:1.0. The most common primary site was lung, followed by stomach and colorectum. MUC1 was expressed by most colorectal, breast and lung adenocarcinoma. MUC2 was expressed infrequently. MUCSAC was expressed by most gastric and colorectal cancer MUC6 was not specific of any primary site in this series. CK7+/CK20+immunophenotype was observed in gastric, lung, colorectal adenocarcinoma. CK7+/CK20- immunophenotype was observed in breast, lung, endometrial, uterine cervical, bile duct adenocarcinoma, while CK7-/CK20+ immunophenotype was observed only in colorectal adenocarcinoma. This results show the utility of TTF-1 to confirm the pulmonary origin. On the other hand ER and PR were not useful markers to assess the origin of primary tumor in this series.

  • Scutellaria baicalensis Georgi is one of major herbs used to treat patients with skin diseases diagnosed by wind-heat syndrome. This study was designed to investigate the effects of Scutellaria baicalensis Extract (SBE) on skin lesion of Contact dermatitis (CD) in mice. We investigated the effects of SBE on skin thickness, skin lesions, erythema index and melanin index in vivo. The effects on body weights and spleen/body weight ratio were also investigated in mice with CD induced by topical application of 1-Fluoro-2,4-dinitrofluorobenzene (DNFB). In our results, topical application of SBE lowered skin thickness significantly. In addition, SBE ameliorated skin lesions such as erythema, exudate and petechia in mice with CD. SBE also inhibited erythema index elevated by DNFB significantly. finally, SBE did not affect body weight and spleen/body weight ratio. In conclusion, these data imply that SBE can ameliorate skin lesion of CD such as erythema, exudate and petechia, and be used to treat CD patients with relative safety.

  • In traditional medicines, Dansam-samul-tang and Samwhang-sasim-tang extracts were known to effects of antioxidant and antimicrobial activity. To investigate the safety evaluation of skin, these extracts were measured to skin safety testing such as primary skin irritation test, eye irritation test and skin sensitization test. The results of the primary skin irritation test and eye irritation test in vitro showed that these extracts included in the nonirritating area. Skin sensitization test results by Guinea Pig Maximization (GPMA) indicated that there was no allergy reaction. Therefore, Dansam-samul-tang and Samwhang-sasim-tang extracts were very safe in every safety test of skin. These results suggests that Dansam-samul-tang and Samwhang- sasim-tang extracts in 1 % concentration can be useful cosmetic ingredients.

  • Background: Numerous studies have explored the influence of XPD Lys751Gln and/or Asp312Asn polymorphisms on skin cancer susceptibility. However, the results remain inconclusive. To derive a more precise estimation, we conducted a comprehensive search to identify all available published studies and performed a meta-analysis. Materials and Methods: Electronic literature searches of the PubMed, CBM and CNKI databases were performed up to March 2014. Odds ratios (ORs) with 95% confidence intervals (CIs) were applied to assess the strength of associations. Results: Seventeen case-control studies were included with a total sample size of 6, 113 cases and 11, 074 controls for the XPD Lys751Gln polymorphism, and 10 studies (3, 840cases and 7, 637 controls) for the XPD Asp312Asn polymorphism were pooled for analysis. Overall, no significant associations were found between the XPD Lys751Gln polymorphism and skin cancer risk in any genetic model. On stratified analysis by tumor type, XPD Lys751Gln polymorphism was not associated with increased risk of non-melanoma skin cancer, but was significantly related with increased risk of cutaneous melanoma (Gln/Gln vs Lys/Lys: OR=1.15, 95%CI=1.02-1.29, p=0.023; dominant model: OR=1.09, 95%CI=1.01-1.18, p=0.036). For the XPD Asp312Asn polymorphism, no significant association with skin cancer risk was observed in overall or subgroup analyses. Conclusions: The present meta-analysis suggests that the XPD Lys751Gln polymorphism may contribute to the risk of cutaneous melanoma from currently available evidence. Further investigations are needed to obtain more insight into possible roles of these two polymorphisms in skin carcinogenesis.
