The epidermal cell-derived thymocyte activating factor (ETAF) produced by keratinocytes and endowed with IL-1 like activities, can potentiate or stimulate a variety of immune reactionsl. In addition to stimulating thymocyte proliferation, it enhanced IL-2 production by mitogen-stimulated lymphocytes. In this study, IL-2 activity stimulated by ETAF was investigated by using peripheral lymphocytes (PBL)and LBRM33 1A5 cell lines. The expression of HLA-DR antigen and the effect of r-IFN-gamma on IL-1 production by keratinocytes were also evaluated : 1. The HLA-DR positive cultured keratinocytes were obser ved in interferon (IFN), interferon-phorbol myristic acid (IFN-PMA) and interferon-lipopolysaccharide (IFN-LPS) groups. There was no HLA-DR expression in the control. PMA. and LPS group. 2. Il-1alpha from supernatants of cultured keratinocytes were produced by all groups including control group. The amounts of IL-1alpha produced by IFN, IFN-PMA and IFN-LPS groups were higher than the other groups. 3. There were no statistical differences between total IL-1alpha from cultured keratinocytes and control or other experimental groups. 4. In experiment for positivie control, the anrounts of IL-2 production by PBL and LBRM33 1A5 cell line were increased proportional to the concentration of added rIL-1. But there was no difference between groups above 1.0 U/ml and 0.5 fmol in LBRM33 1A5 cell line. 5. the production of IL-2 by PBL were increased by phytohemagglutinin (PHA), PHAPMA and PHA-LPS groups. There were no production of IL-2 in control, IFN, LPS, only LPS added group, and IL-1alpha. The IL-2 induced by PHA-PMA group was much higher than the other groups. The production of IL-2 was stimulated by IL-1 of supernatarnts and cell lysates from the cultured keratinocytes, but here was no correlation between IL-2 production and added IL-1. 6. The production of IL-2 by LBRM33 IA5 were increased by PHA, PHA-PMA and PHA-LPS groups. There were no production of IL-2 in the other groups. In summary, the results suggest that supernatants and cell lysates from cultured keratinocytes can stimulate the IL-2 production by human PBL and LBRM33 1A5 cell line. Therefore the ETAF can potentiate or stimulate the immune reactions and enhance IL-2 production by mitogen-stimulated lymphocytes.

BACKGROUND: The main function of melanocyte is known to protect the skin from hazardous sunlight. But, some investigators have claimed lately that melanocytes are also related to the immunologic role in the epidermis because these cells produce IL-1 activity and IL-1beta convertase activity, in vitro. OBJECTIVE: Our purposes were to investigate the effects of rIFN-gammaon the proliferation of melanocytes, melanin content, and the expression of HLA-DR antigen on melanocytes after a rIFN-gammaexposure. MEHTODS: The number of melanocytes, the melanin content, and the expression of HLA-DR antigen were evaluated on cultured human melanocytes according to a time sequence and various concentrations of rIFN-gamma. RESULTS: Antiproliferative activity on melanocytes was dependent on the exposure time and the concentration of rIFN-gamma. According to the exposure time and the concentration of rIFN-gamma, melanogenic acivity was inhibitd or stimulated. Normal melanocytes didn't express HLA-DR antigen, but when normal melanocytes were exposed to rIFN-gamma, the expression of HLA-DR antigen increased in a time-and concentration-dependent fashion. After the removal of rIFN - gammafrom the culture media, the expression of HLA-DR antigen on melanocytes also disappeared. CONCLUSION: In our study, melanocytes seem to be related to the immunologic role in the epidermis because these cells expressed HLA-DR antigen after rIFN-gammaexposure and we think that study could help to investigate between melanocytes and immunologic mechanisms in various inflammatory skin diseases.

BACKGROUND: Meralgia paresthetica (MP) is a mononeuropathy affecting the lateral femoral cutaneous nerve. The disease is often diagnosed clinically, but electrophysiological tests play an important role. The aim of this study is to clarify clinical characteristics of MP as well as the role of sensory nerve conduction study (NCS) in the diagnosis of MP. METHODS: Sixty-five consecutive patients with clinical diagnosis of MP between March 2001 and June 2012 were retrospectively reviewed at a single tertiary center. General demographics, clinical characteristics and sensory NCS findings were investigated. Measurements of sensory NCS included the baseline-to-peak amplitude, side-to-side amplitude ratio and the conduction velocity. To compare between the normal and abnormal NCS groups, independent t-tests and chi-square test were performed. RESULTS: Sixty-five patients had male predominance (56.9%) with mean age of 48.4+/-13.4 years (range: 16-75). Seven patients (13.5%) had undergone operation or procedure before the symptom onset. The sensory nerve action potentials were obtainable in 52 (80%) of 65 clinically diagnosed MP patients. Sensory NCS revealed abnormalities in 38 patients (73.1%), and others (n=14, 26.9%) showed normal findings. Between the normal and abnormal NCS groups, there is no statistically significant difference on demographics or clinical features. CONCLUSIONS: We clarify the clinical features and sensory NCS findings of MP patients. Due to several limitations of sensory NCS, the diagnosis of MP could be accomplished both clinically and electrophysiologically.

Klippel-Trenaunay syndrome (KTS) is a rare congenital malformation syndrome involving blood and lymph vessels, which is characterized by triad of cutaneous hemangioma, venous varicosities, and overgrowth of the affected limbs. Because vascular malformation in KTS can be located anywhere except the face and brain, the clinical presentation could be extremely variable. But there are only rare case reports that KTS is associated with spinal cord lesion. We report a case of recurrent myelopathy in a patient with KTS.

BACKGROUND: Infections are usually related to the surgical patients prognosis. Therefore consultations from surgical departments to division of infectious diseases are considered very important in the aspect of improvement of surgical outcomes and control of hospital infection. This study was conducted to analyze the results of infectious disease consultation from surgical departments. MATERIALS AND METHODS: We retrospectively reviewed 624 cases of consultation to division of infectious diseases from surgical departments from March to August in the year of 2002. RESULTS: Among 624 cases, 610 were included; 292 cases (47.9%) were new and 318 cases (52.1%) were follow-up requests. More than 50% of consultations were from the department of neurosurgery and orthopedics. Overall, 558 cases (91.4%) were about infection-related conditions, and among them, common causes were soft tissue infection, respiratory tract infection, and urinary tract infection. However, those results were remarkably variable according to each surgical department. The measures taken after consultations were change of antibiotics (35.6%), maintenance of antibiotics (18.4%), discontinuance of antibiotics (10%), start of antibiotics (9.2%), and observation without antibiotics (4.3%). CONCLUSION: This is the report on analysis of infectious disease consultation from surgical departments. Through the analysis of consultations we expect to enable more efficient care of patients and infection control.

A pulmonary thromboembolism usually results from deep vein thrombosis as a serious and fatal complication. It is well known that several risk factors are predisposed to these thrombotic events, causing sudden death. Recently, new variant forms of pulmonary thromboembolism, termed as "economy class syndrome or e-thrombosis" were reported in association with sitting for long time in aircraft seat or at computer. The authors experienced a case of death developed after prolonged gambling at casino in 46-year-old man and concluded that the cause of death was fatal pulmonary thromboembolism due to deep vein thrombosis, associated with prolonged sitting. Therefore, the author thought that this case may be contribute to another possible risk factor of life-threatening pulmonary thromboembolism and highlights the importance of predicting deep vein thrombosis after prolonged gambling in sitting position at casino in the similar mechanism of aforementioned reported cases.

BACKGROUND: Metabolic syndrome, a concurrence of disturbed glucose and insulin metabolism, over- weight and abdominal fat distribution, dyslipidemia and hypertension, is associated with subsequent de- velopment of type 2 diabetes mellitus and cardiovascular disease, especially coronary heart disease. The aim of the study is to assess the relationship between metabolic syndrome and coronary heart disease in elderly greater than 65 years old. METHODS: Eighty two elderly patients greater than 65 years old who underwent coronary angiography were divided into two groups with metabolic syndrome or without metabolic syndrome, and assessed the association with coronary angiographic finding. The metabolic syndrome factors and cardiovascular risk factors of JNC 7 were investigated to assess the relationship with coronary heart disease in elderly. Coronary heart disease was defined as 50% or greater diameter in stenosis of coronary artery in coronary angiography. RESULTS: In elderly patients with metabolic syndrome, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p<0.05) were presented significantly higher than non metabolic syndrome patients. In elderly patients with 3 and more cardiovascular risk factors of JNC 7, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p=0.059) were presented more than the other patients. Diabetes mellitus was related significantly with coronary heart disease(p value 0.044). CONCLUSION: In elderly patients, metabolic syndrome was significantly related with coronary heart disease and diabetes mellitus had strong relationship with coronary heart disease. Metabolic syndrome and cardiovascular risk factors of JNC 7 should be further evaluated to assess the relationship with coronary heart disease in the future.

Cases of acute myocardial infarction (AMI) that occurs during pregnancy or postpartum are rarely reported. Ergot derivatives were known to induce spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI even in normal healthy people. Several cases are also reported that ergot derivatives may trigger severe AMI in postpartum period. Here, we report a case of a forty-year-old pregnant woman who was succeeded to be pregnant by artificial fertilization died after treatment with ergot derivatives. Examinations of autopsy have revealed AMI with severe coronary atherosclerosis. This case is the first report which shows aggravation of preexistent severe coronary atherosclerosis after postpartum infusion of ergot derivatives.
