It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.

We report a case of multiple Bowen's disease associated with leprosy. A 68-year-old man was seen because of slightly pruritic multiple erythematous scaly patches and plaques on the trunk and the both extremities for 5 years. He has been treated for leprosy with many kinds of drugs consisting of the herb medications for over 40 years. He also showed decreased cell-mediated immunity in skin tests. It is considered that depressed cellular immunity may be an important predisposing factor in the development of mutiple Bowen's disease in this case, .although arsenics can not be completetly excluded.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.

BACKGROUND: thermotherapy has been shown to be effective in the treatment of some fungal infections. Dermatophyte are well grown at 25degrees C rather than 37degrees C or high temperature. OBJECTIVE: An vitro test was done to assess the complemental effect and optimal conditions of local heating on the susceptability of t. rubrum to systemic antifungal agents. METHODS: Microdilution susceptability test to ketoconazole and itraconazole was done using 96 well microplate. Eight strains of T. rubrum were isolated from patients withtinea pedis and were cultured at 25degrees C, 37degrees C and 42degrees C for 1, 8 or 24 hours per day. MIC were checked at 4th, 7th, 9th day after inoculution. RESULTS: The growth without antifungal agents at 37degrees C and 42degrees C were decreased by 805 and 50% of the growth at 25degrees C respectively. Seven day after inoculation was the proper time to check the MIC. MIC50 of ketoconazole was the lowest at 42degrees C for 24hours per day in value of 0.006microgram/ml, and 0.09microgram/ml at 37degrees C for 24hours per day, 0.37microgram/mlat 42degrees C, for 8hours per day and 37degrees C for 8hours per day. MIC at 42degrees C for 1 hours er day, 37degrees C for 1 hyours and 25degrees C for 24hours per ady MIC were the same in value of 0.05microgram/ml. MIC50 of itraconazole was the lowest at 42degrees C for 24hours per day in value of 0.006microgram/ml, 0.01microgram/ml at 37degrees C for 24hours per day, 0.02microgram/ml at 37degrees C for 8hours per day. MIC at 42degrees C for 8hours per day, 42degrees C for 1hours per day, 37degrees C for 24hours per day MIC were the same in value of 0.05microgram/ml. CONCLUSION: Incubation at 37degrees C for 24 hours per day or 42degrees C for 24 hours per day increased the susceptability of T. rubrum to ketoconazole and itraconazole.

The cryopathic hemolytic anemia is an autoimmune hemolytic anemia induced by cold antibody. Authors report a case of cryopathic hemolytic anemia confirmed by immunohematologic examination. A 22-year-old man was admitted at Kyung Hee Medical Center in March, 1994, with a past history of Kleinerfelter's syndrome and complained jaundice as well as dizziness. Direct antiglobulin test using polyvalent and anti-C3d monovalent antisera was positive, but was negative against anti-IgG, anti-IgA, and anti-IgM monovalent antisera. Cold agglutinin titer was as high as 1:1024 at 4 degrees C and anti-I specificity was confirmed by using cord bloods. The patient was not improved despite transfusion of washed red cells and administration of prednisolone, and on 16th day of hospitalization he manifested sudden episode of headache and loss of conscioussness, soon followed by death.
