Basal cell carcinoma is a malignant epithelial neoplasm of the skin and the most common human skin cancer. It is generally associated with a good prognosis. In this case report, a giant basal cell carcinoma of the nodulo-ulcerative type showing wide ulceration with marginal multiple small nodules, is presented. It was trapezoidal in shape, having dimensions of 7 cm at the greatest basal width, 6 cm vertically with different anterior and posterior margin dimensions, and 5 cm horizontally at the top margin. After wide excision of the lesion including 5-10 mm safety margins, the wound was reconstructed with a local skin flap and split-thickness skin graft. The reconstructed wound healed well without recurrence for 1 year.

This study was conducted to obtain hydrolysates with potent antioxidative activity from rockfish skin gelatin. Gelatin was extracted under high temperature/high pressure using a two-step enzymatic hydrolysis with commercial enzymes such as Alcalase, Flavourzyme, Neutrase, and Protamex. The second rockfish-skin gelatin hydrolysate (SRSGH) was prepared by further incubating the first gelatin hydrolysate (FRSGH), which had been hydrolyzed with Alcalase for 1-h (FRSGH-A1), with Flavourzyme for 2-h (SRSGH-F2). The second gelatin hydrolysate showed higher antioxidative activity of 3.72 as measured by a Metrohm Rancimat and superior angiotensin I-converting enzyme (ACE) inhibiting activity of 0.82 mg/mL. Compared with the gelatin, the relative proportion in SRSGH-F2 was markedly decreased in the 100-kDa peak, whereas it was increased in that less than 100-kDa. The amino acid composition of SRSGH-F2 was rich in glycine (25.9%), proline (10.8%), alanine (9.1%), and glutamic acid (9.1%). In contrast, it was poor in cystine (not detected), methionine (1.6%), tyrosine (0.4%), hydroxylysine (0.9%), and histidine (0.9%). In recent years, demand for natural functional foods has been increasing, and SRSGH-F2 can be used as a functional food ingredient in the food industries. However, further detailed studies on SRSGH-F2 with regard to its antioxidant activity in vivo and the various antioxidant mechanisms are needed.

Introduction: Qūbā (Tinea Corporis) is a very common disease widely prevalent worldwide. 20 - 25 % individuals suffer for this stubborn disease. Unani System of Medicine offers its treatment. There are many pharmacopoeial formulations indicated for various types of dermatophytic infections. In this study clinical efficacy and safety of the topical Unani formulation Marham Kharish Jadeed (a compound drug in the dosage form of an ointment) was assessed and compared with a standard conventional medicine. Materials and methods: A clinical study was conducted on 60 participants of qūbā randomized into test and control groups (n=30 in each group). The participants were clinically diagnosed and confirmed by microscopy of skin scrapings. The efficacy of the Unani formulation was assessed in terms of TSS score and elimination of fungal elements from the skin lesions. The data collected were analyzed statistically. Results and discussion: The study showed that the Unani formulation had comparatively better efficacy clinically than conventional medicine Terbinafine hydrochloride 1% cream in terms of reduction of itching, erythema, scaling, peripheral raised margins of the lesion comparing to baseline. In this study, 27 participants in test group and 18 participants in control group were completely cured (≥75% reduction in TSS Score with Mycological Cure) after 4 weeks of treatment. The efficacy of the Unani formulation was found significant statistically. The individual drugs of the formulations having analgesic (Musakkin), blood purifier (Muṣaffi-i-Dam), demulcent (Mulaṭṭif), antifungal (Qātil-i-fafūndῑ), detergent (Jālῑ), refrigerant (Mubarrid) and antiseptic (Dāfi'-i-'Ufūnat) properties might be responsible for the efficacy of Unani formulation. Conclusion: The findings of the study suggested that the Unani formulation was found effective and safe in the management of qūbā. No local and systemic adverse effect was reported during the study.

H-pile can be more easily driven than pipe pile by pile driver and shows high skin friction and plugging effect. And lately It is well grown that the high strength H-pile has been widely used f3r pile foundations. To compare the skin frictions of H piles under different density soil conditions, this paper presents results of a series of model tests on vertically loaded group piles. Model piles made of steel embedded in weathered granite soil were used in this study. Pile arrangements $(2\times2,\;3\tunes3)$, pile space(2D, 4D, 6D), and soil density$(D_r=40\%,\;80\%)$ were tested. The main results obtained from the model tests can be summarized as follows. The series of tests found that compression load for group piles increases as number of piles increase and piles space ratic decrease to $D_r=40\%$ of soil density. The analysis also found that the theoretical value of skin friction for group piles is greater than practical value as piles space ratio increases to $D_r=40\%$ of soil density. Piles showed the greatest difference of the skin friction in case that the pile space ratio(S/D) is 6. The theoretical value by Meyerhof and DM-7 showed 1.83 times and 1.32 times respectively as great as practical value in case of S/D=6 and $2\times2$.

Objectives: This study was carried out to identify relation of health care utilization due to skin disease(ICD-10, L00-L99) and characteristics(sex, age, exposure status, type of industry, size of enterprise) of workers. Methods: We made new database composed of 30,536 workers' health examination results in one specific health examination institute in Inchon and data of medical insurance utilization due to skin disease in 4 medical insurance associations for enterprise from January, 1995 to December, 1997 And we analyzed determinants of health care utilization due to skin disease of workers. Results: Among 30,536 study subjects, 8,837(28.9%) workers and 4,181 (13.7%) workers utilized medical insurance due to total skin disease(ICD-10, L00-L99) and contact dermatitis(ICD-10, L23-L25), respectively. Female workers(p<.001), workers exposed to organic solvents(p<.05), workers if manufacturing industries(p<.05, p<.01, respectively) and in large scale enterprises(p<.001) utilized more medical insurance due to total skin disease and contact dermatitis than male workers, workers not exposed to organic solvents, workers in non-manufacturing industries and small scale enterprises. With multiple logistic regression analysis, significant explanatory variables affecting workers' medical utilization due to total skin disease and dermatitis and eczema(ICD-10, L20-L30) in total workers were sex, age, specific chemicals and size of enterprises. And age, type of industries, organic solvents, specific chemicals and size of enterprises were significant explanatory variables related to medical insurance utilization due to dermatitis and eczema and contact dermatitis in male workers. Conclusion: From the above results, we found that workers exposed to organic solvents utilized more medical insurance due to skin disease than workers not exposed to. And, comparing to workers in large scale enterprises, workers in small scale enterprises may have unmet medical care utilization due to skin disease. Therefore we have to establish counterplan to manage occupational skin disease of high risk group(organic solvent exposure group) and to satisfy unmet medical care utilization of workers in small scale enterprises.

The toxicity of five species of puffer fish, Arothron firmamentum (Byeolbok), Lagocephalus gloveri (Heukmilbok), L. wheeleri (Eunmilbok), L. inermis (Minmilbok) and L. lunaris (Milbok), collected from fish markets in Korea, was determined using a mouse bioassay. In A. firmamentum, the proportion of toxic specimens containing >10 MU/g was 87.5% in the ovaries, and 10.0% in the skin; no toxicity was detected in the muscle, fin, liver, intestine and gallbladder using the mouse bioassay. The highest toxin levels were found to be 87 MU/g in the ovaries, and 13 MU/g in the skin. Toxic specimens containing >10 MU/g were not detected from samples taken from any of the organs in L. wheeleri and L. inermis. In L. gloveri, most specimens were found to be non-toxic, but toxin levels of 11-72 MU/g were detected from within the skin, fins, and intestines in one specimen. In L. lunaris, the proportion of toxic specimens was 50.0% in the ovaries, and 7.1% in the gallbladder; no toxicity was detected in the other organs by the mouse bioassay. The highest toxin levels were 75 MU/g in the ovaries, and 14 MU/g in the gallbladder. Therefore, the toxicities of edible muscle and skin in the five species of puffer fish marketed in Korea were found to be within acceptable levels for human consumption.
