OBJECTIVES: This research was intended to investigate the relationship between manganese and malodndialdehyde concentration in tissues of rats exposed to maganese chloride. METHODS: The study groups were 12 manganese treated rats and 9 control rats. Manganese treated rats were given intraperitoneally manganese chloride (Mn, 4 mg/kg) daily for a period of 30 days except Sunday. Control rats were injected 1ml of saline. The plasma manganese concentrations of rats were determined by graphite furnace atomic absorption spectrometry. The tissue manganese concentration was determined by flame atomic absorption spectrometry. Malondialdehyde, the product of lipid peroxidation was determined by ultraviolet-visible spectrophotometry. The plasma malondialdehyde was determined by gas chromatography with mass-detector. Protein concentration was quantified by ultraviolet-visible spectrometry and was used for the compensation of tissue malondialdehyde and manganese concentration. RESULTS: Manganese concentrations of plasma, brain, liver, and pancreas were very significantly higher in the manganese-treated rats than in the control rats. Malondialdehyde concentration of plasma, brain, and pacrease were significantly higher in the manganese-treated rats than in the control rats. The concentration of malondialdehyde was correlated with manganese levels in plasma, brain and pancreas. Conclusion: Based on the results obtained as above, it was concluded that the malondialdehyde, product of lipid peroxidation was related to the cell death due to dosing excess manganese.

Fracture of capitellum humeri, so called Kocher fracture, was first described by Haln in 1853. It is rare and has been occured 0.5% to 1% of incidence of all elbow fracture. The mechanism of this fracture mostly results when one tries to break a fall and lands on the hand with the elbow in some degree of flexing or falls directly on the elbow in a position of full flexion. This case had been occured in a secondary motion

A 26-year-old man presented with a bluish speckled patch on the dorsum of the left hand. It had apperaed at birth as a bluish spot. Since adolescence the lesion extended and at the time of visiting hospital it covered the most part of the dorsum of the left hand and even some palmar aspect. The histopathological and ultrastructural examination revealed numerous dermal melanocytes, mainly in the upper dermis. Clinically and pathologically, the patient was diagnosed as having dermal melanocyte hamartoma, a distinct type of dermal melanocytosis.

l6-year-old male and 48-year-old female with systemic lupus erythematosus (SLE) and renal disease presented with vesiculobullous eruptions during severe attack of the disease. They showed hypocomplementernia, and high ANA titers. Histopathologic findings revealed subepidermal blister and leukocytoclastic vasculitis, Direct immunofluorescence demonstratedlinear deposits of IgG, IgA and lgM at the dermoepidermal junction. The vesiculobullous eruption of SLE may be an important marker reflecting disease activity and prognosis.

Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior and interest. Sleep problems are not uncommon in children with autism spectrum disorders. Symptoms of insomnia are the most frequent sleep problems in individuals with ASD. Sleep problems can cause significant difficulties in the daily life of children with ASD and their families. Genetic factor, deregulations of melatonin synthesis, extraneous environmental stimuli and psychiatric and medical conditions may cause sleep problems. The first line treatment of sleep problems in ASD includes managements for potential contributing factors and parent education about sleep hygiene care for child and behavioral therapy. Supplementation with melatonin may be effective before considering other medications, such as risperidone, clonidine, and mirtazapine.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

OBJECTIVES: The aims of this study were to evaluate changes in plasma superoxide dismutase(SOD) activities in alcohol depedence, to fine out variables to influence on the SOD activities, and finally to identify the correlation of SOD activities with the alcohol-associated cognitive disorders. METHODS: For 24 male alcoholics and 21 healthy male controls, plasma SOD activities were measured by spectrophotometry on 1-2 wks after alcohol withdrawal. Structured interviews and laboratory tests were also performed. RESULTS: 1) Upon comparing SOD activities between controls and alcoholics, the SOD activities were significantly(p<0.01) lower in alcoholics(0.308+/-0.140 units/mL) than in healthy controls(0.313+/-0.086 units/mL). 2) Upon comparing SOD activities according to the presence of alcohol-related cognitive disorders, the SOD activities were significantly(p<0.05) lower in alcoholics with cognitive disorders(0.247+/-0.049 units/mL) than in alcoholics without cognitive disorders(0.317+/-0.148 units/mL). 3) Upon comparing SOD activities according to the presence of alcoholic polyneuropathy or alcohol withdrawal seizure, the SOD activities showed no significant differences between alcoholics with polyneuropathy or epilepsy and those without. 4) Upon analyzing variables influencing on the SOD activities in alcoholics, the SOD activities had the negative correlation with hemoglobin(gamma=-0.433) and severity of alcohol withdrawal symptoms(gamma=-0.375). 5) Upon comparing variables according to the presence of alcohol-related cognitive disorders, the occurrence of alcoholic polyneuropathy(p<0.05) and blood phosphorus concentrations(p<0.01) were significantly higher in alcoholics with cognitive disorders than those without. 6) Upon analyzing an association between SOD activities and variables in alcoholics with cognitive disorders, the SOD activities were positively correlated with the onset age(gamma=0.995), and negatively correlated with the severity of alcohol withdrawal symptoms(gamma=-0.996). CONCLUSIONS: Lower SOD activities in alcohol dependence suggested alcohol-associated cognitive disorders and alcohol withdrawal symptoms might be caused by oxidative stress.
