Spitzoid melanocytic lesions may be broadly categorized into Spitz nevi, atypical Spitz tumor (AST), and spitzoid melanomas. Atypical Spitz nevi, also known as AST is rare spitzoid melanocytic proliferations with an uncertain malignant potential and described as conventional Spitz nevi with 1 or more atypical features with indeterminate biological potential. It has clinical features of larger size (>6 mm), irregular borders, irregular topography, or ulceration. Threre are no definite histologic diagnostic criterias among spitzoid melanocytic proliferations, but asymmetry, ulceration, pagetoid melanocytosis, lack of maturation, deep mitoses, and atypia are distinct findings of atypical Spitz nevi. A 2-year-old man presented with several months of pigmented nodule on right knee. Skin biopsy from right knee showed spitzoid melanocytic proliferation from the epidermis to the reticular dermis. Melanocytes arranged in nests were epithelioid with abundant eosinophilic cytoplasm. Each cells showed uniform pleomorphism and mitosis, but there were no atypical mitosis. Few kamino bodies in epidermis and outlier cells in reticular dermis were also detected. Immunohistochemical study revealed positive of HMB-45, S-100, P16 and Ki-67 over 30 percent. We report a case of atypical spitz nevi and distinguishing features of spitzoid melanocytic proliferations through literature review.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

Objective: To evaluate hyperlipidemia, a msjor tisk factor of coronary artery disease, frequently asscoiated with gout patients, we compared the mean lipid level of gout patient with that of non-gout male and accessed statistical significance for treatment of gout patient. Method: This study ws performed in the 266 male gout outpatients of the CAU medical center, who had serum lipid level test from Apr. 1996 to Aug. 2000. Serum uric acid, total cholesterol, triglyceride, HDL -cholesterol, and LDL-cholesterol level were measured after 12 hours of fasting. The patients with high lipid level were further evaluated into each type of the hyperlipidemia through electrophoresis study, and the test results were compared with that of the non-gout male adults(40∼60yr), and the statistical significance was examined. Results : The gout patients showed high levels of total cholesterol, triglyceride, and LDL-cholesterol. Especially they showed high level of triglyceride and LDL-cholesterol which suggested as the risk factors of atherosclerosis and coronary heart disease, but shoewed low level of HDL -cholesterol. But there were no definite relations between lipid level and other factors auch as age of patient, initial uric acid ;eve; and duration od gout. Conclusion: To evaluate the risk factors of atherosclerotic change of cadriac vascular system in gout patient, screening tests of serum lipid level of the patient seem mandatory.

Peroxidase has been partially purified from earthworm, Lumbricus rubellus, using ammonium sulfate fractionation, Sephacryl S-200 gel filtration, CM-cellulose cation exchange chromatography and native-PAGE elution. Some of its enzymatic characteristics were examined. Earthworm peroxidase showed the characteristics of heat-sensitivity, and the enzyme activity was stimulated in the presence of various cations. The most available booster was CoCl₂, followed by ZnCl₂and KCl among cations used. The optimum pH for guaiacol oxidation of earthworm peroxidase was determined to be 6.0, and the Km values against guaiacol and H₂O₂were 1.25mM and 3.4 mM, respectively. When various compounds were tested as the possible substrates of the enzyme, o-dianisidine was used as the substrate. However, earthworm peroxidase could not oxidize esculetin and ferulic acid as substrates, suggesting the different characteristics of the enzyme from plant peroxidases. The opimum pH for veratryl alcohol and H₂O₂oxidation was determined to be 2.5 when lignin peroxidation activity was examined. The Km values for veratryl alcohol and H₂O₂were 0.02 mM and 0.13 mM, respectively.
