  • This study was performed to investigate the effect of low power laser irradiation on epidermal growth factor(EGF) expression in the burned skin of the rats. Burns of about 3cm in diameter were created with 75'c water on the back of the rats, and the lesion of experimental group were irradiated on days 1, 2, and 3 postwounding. Control tensions were not irradiated. After burns, low power laser irradiation was applied by using 1000Hz, 830nm GaAlAs (Gallium-aluminum- arsenide) semiconductor diode laser. The expression of epidermal growth factor evaluated immunohistochemistry on mouse anti-EGF. The results of this study were as follows 1. In expression of EGF, the lesion of experimental group made EGF to more induce significantly than control tensions. 2. EGF immunoreactivity in burned skin were increased markedly 3 days after burns, and increased gradually from 1 day to 2 days in burns which is laser irradiation These data suggest that low power laser have wound healing effect in the burned skin of the rats.

  • In the theory of Korean medicine, Angelicae Dahuricae Radix (ADR) can expel wind and relieve exterior syndrome, and eliminate dampness. Recently, ADR has been reported to have possibilities as anti-inflammatory agent and cosmetics. The purpose of this study is to evaluate the efficacy of ADR on contact dermatitis (CD). In order to investigate the anti-inflammatory effects of ADR on CD, we investigated the effects of ADR on ear thickness, ear weight, skin lesion and histopathological changes in mice with CD induced by 1-fluoro-2,4-dinitrofluorobenzene (DNFB). In addition, the effect on spleen weight was also measured. In our results, topical application of ADR lowered ear thickness and weight respectively. ADR treatment also improved skin lesions such as erythema and scale. In the histopathological observation, ADR-treated group showed diminished epidermal hyperplasia and immune cell infiltration in inflammed tissues compared to those of non-treated control group. In conclusion, These data suggest that ADR has anti-inflammatory action in inflammed skin tissue, resulting in improving skin lesion and histopathological abnormalities of CD.

  • Background: Skin biopsy is the method to assist clinicians to make definite dermatological diagnosis which further helps in holistic management. Skin cancers are relatively rare clinical diagnosis in developing countries like Nepal, but the prevalence is on rise. Objectives: To investigate the profile of skin biopsies and frequencies and pattern of skin cancers in a tertiary care centre of Western Nepal. Materials and Methods: The materials consisted of 434 biopsies (1.37%) out of 31,450 OPD visits performed in the Department of Dermatology, Manipal Teaching Hospital, Pokhara, Nepal, during the period of Dec 2011-Nov 2014. Data were collected and analyzed using SPSS-16 with reference to incidence, age, sex, race and clinical and histopathological features. Results: The commonest disorders observed in biopsies were papulosquamous lesions, skin tuberculosis of different types, benign skin tumors, leprosy, collagen and fungal diseases. Viral diseases were rarely seen, probably due to straight forward clinical diagnosis. Dermatological malignancies accounted for 55/434 (12.67%) of biopsies. Skin disorders in general were commoner in females 280/434 (64%), including malignancies 32/55(58.2%). Mean age of patients with skin cancer was 54.5 years. Facilities for proper laboratory investigation of dermatological disorders will improve the quality of life. Conclusions: The most prevalent lesion in skin biopsies was papulosquamous disorders followed by skin tuberculosis of different types. Dermatological malignancy constituted 55/434 (12.67%) cases. The prevalence of skin malignancy is on rise in Nepalese society probably due to increase in life expectancy and better diagnostic services.

  • Staphylococcus intermedius (S. intermedius) has been rarely isolated from horse. In this study, we investigated the antimicrobial susceptibility patterns of S. intermedius isolated from skin lesions of Thoroughbred horse in Daegu Equestrian Association. The skin lesions were showed with dehairing and slight purulent inflammation. Bacteria were isolated from skin lesions and identified as S. intermedius by biochemical tests and MicroLog (BIOLOG, California, USA). Antimicrobial susceptibility test of S. intemedius isolates was performed with 33 antimicrobial agents (BBL, Maryland, USA) by using the agar disk diffusion method. It showed a high sensibility in the amikacin, amoxycillin/clavuramic acid, ampicillin, cefoxitin, cephalothin, chloramphenicol, ciprofloxacin, enrofloxacin, florfenicol, kanamycin, neomycin, nitrofurantoin, norfloxacin, ofloxacin, oxacillin, penicillin G, tetracycline and vancomycin. The horse was treated with penicillin, and cured completely after two weeks. The present results showed valuable information for treatment and prevention of skin disease in horse.

  • Flavonoids are known as natural anti-inflammatory agents. In this investigation, an anti-inflammatory potential of new topical preparation (SK Ato $Formula^{\circledR}$) containing flavonoid mixtures from Scutellaria baicalensis Georgi roots and Ginkgo biloba L. leaves with an extract of Gentiana scabra Bunge roots was evaluated in an animal model of chronic skin inflammation. Multiple 12-O-tetradecanoylphorbol-13-acetate treatments for 7 consecutive days on ICR mouse ear provoked a chronic type of skin inflammation: dermal edema, epidermal hyperplasia and infiltration of inflammatory cells. When topically applied in this model, this row formulation $(5-20\;{\mu}L/ear/treatment)$ reduced these responses. Furthermore, it inhibited prostaglandin $E_2$ generation (17.1-33.3%) and suppressed the expression of proinflammatory genes, cyclooxygenase-2 and $interleulin-1{\beta}$ in the skin lesion. Although the potency of inhibition was lower than that of prednisolone, all these results suggest that Ato $Formula^{\circledR}$ may be beneficial for treating chronic skin inflammatory disorders such as atopic dermatitis.

  • Metastasis of lung cancer to the skin is uncommon, presenting in 0.22% to 12% of lung cancer patients, and it is extremely rare for skin metastasis to be the first clinical manifestation of lung cancer. In the few cases where skin metastasis has been reported as the first sign of lung cancer, the patients were typically heavy smokers or had preexisting respiratory diseases and symptoms. This prompted clinicians to consider skin metastasis of a pulmonary malignancy. Large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer that accounts for approximately 3% of lung cancers. LCNEC mainly metastasizes to visceral organs, such as the liver, bone, and brain, and it only shows metastasis to the skin in very rare cases. Herein, we report an unusual case of a metastatic skin lesion as the first sign of primary pulmonary LCNEC, in a 63-year-old woman with no pulmonary symptoms or personal history of smoking or pulmonary disease.

  • Angiolymphoid hyperplasia with eosinophilia(ALHE) is an uncommon, benign vascular proliferation with the background of a stroma which is heavily infiltrated by lymphocytes and eosinophils and includes lymphatic follicles with prominent germinal centers. ALHE primarily involves the skin and subcutis in head and neck as various forms of nodules. There has been considerable controversy about the relationship between ALHE and Kimura's disease. Kimura's disease, originally reported by Kimura et el., is an unusual granulation with proliferation of lymphoid tissue. Wells and Whimster published the first report describing a condition that resembled Kimura's disease and designated it as ALHE. For a time being two lesions are thought to be same lesion, but recently they are considered as two different entities, histopathologically. The cause of this disease remains unknown, and physicians have used a variety of treatment modalities including cryosurgery, steriod therapy, electrodesiccation, curettage, radiotherapy, laser therapy and surgical excision. But any treatment modality leaves problem of recurrence because the lesion is not well encapsulated. Being poorly encapsulated, the lesion's remnants are apt to be left and this markes some problems : recurrence and possible adjacent organ injury. In this case we misdiagnosed the lesion as well encapsulated benign mass. We performed excisional biopsy and experienced prolonged operation time and unwanted mentalis muscle injury. We think that the importance of poor encapsulation of ALHE should be stressed. So we report our experience with literature review.

  • Intraosseous hemangioma is a rare, slow-growing, benign tumor of blood vessels. Primary hemangioma of the skull is a benign lesion that may appear as a palpable mass or accidentally detected during image evaluation. Simple radiography is the most commonly used technique to localize a lesion and computed tomography (CT) may help determine the effect of a lesion. We report a case of multifocal intraosseous calvarial hemangioma developed in the subgaleal plane of an elderly male patient. Ultrasonography examination revealed hyperechoic striated septae parallel to the skin and discontinuity of the focal cortex, however, the underlying bone cortex appeared relatively intact. No significant flow is observed on Doppler ultrasonography. Based on these evaluations, the mass was interpreted by a radiologist as a subgaleal lipoma. This case highlights the importance of additional CT examination in a patient presenting with a scalloping sign of the underlying calvarium. Clinicians also should be aware of the possibility of intraosseous calvarial hemangiomas in lesion. Furthermore, the proper choice of congenital vascular malformation term is still quite confusing with misconception present in the literature.
