PURPOSE: The detrimental effect of strenuous exercise is well documented. The effect of moderate exercise (weight training and aerobic exercise) in healthy men was evaluated by analyzing the trend of hormones responsible for male reproduction. MATERIALS AND METHODS: The subjects were divided into 3 groups: systemically trained by a combination of bench press, sit-up and leg squat by 70% of 1RM for 10 weeks in the weight training group (n=5), systemically trained by a combination of treadmill running or walking by 70% of HRmax for 10 weeks in the aerobic exercise group (n=5), and non-training control group (n=5). RESULTS: In the weight training group, there were significant reductions of serum testosterone, FSH and LH during exercise (p>0.01). There was no difference in hormone values between weight training and aerobic groups for any of the hormones measured. CONCLUSIONS: Weight training and aerobic exercise lowered the serum FSH and LH levels, suggesting that moderate exercise may positively affect the reproductive hormonal status of males.

An endobronchial metastasis is defined as a subsegmental or a more proximal central bronchial metastasis of a nonpulmonary neoplasm in the bronchoscopically visible range. However, the frequencies of endobronchial metastasis range from 2 to 50% of pulmonary metastases from extrathoracic neoplasms by a different difinition of an endobronchial metastasis. Primary neoplasms of an endobronchial metastasis including breast cancer, colon cancer, renal cell carcinoma, and ovarian cancer are relatively common. However, an endobronchial metastasis arising from thyroid cancer, parotid gland tumor, bone tumor, bladder cancer, and stomach cancer has only rarely been reported in the literature. Here we report a case of an endobrochial metastases from a hepatocellular carcinoma

Cytomegalovirus is a frequent opportunistic pathogen in immunosuppressed patients and CMV colitis is one of its major complications. It usually presents as gastrointestinal ulceration with bleeding or perforation, but it can also take less common forms resembling many other entities, including viral gastroenteritis, ischemic colitis, intestinal pseudo-obstuction, toxic megacolon. We experienced a 49-year-old man with symptom of severe constipation and lower abdominal pain. He was diagnosed as having focal segmental glomerulosclerosis by renal biopsy, but he was an immunocompetent state. An abdominal X-ray showed marked dilatation of descending colon without air-fluid level. At colonoscopy and biopsy, he was diagnosed as having CMV colitis with focal stenosis. Treatment for two weeks with ganciclovir resulted in resolution of colitis, but stenosis was remained. We report a case of toxic megacolon and focal stenosis due to CMV colitis in a FSGS patient. It was not certain whether FSGS was related with immunosuppressive state.

BACKGROUND/AIMS: To diagnose autoimmune pancreatitis (AIP), serum IgG and IgG4 concentration are significant serologic markers. The purpose of this study was to assess the utility of serum IgG and IgG4 for the diagnosis of AIP. METHODS: We divided enrolled patients into 2 groups: autoimmune pancreatitis and other pancreatic disease. We measured serum IgG and IgG4 levels in patients including 12 AIP and 23 other pancreatic disease. RESULTS: Among AIP patients, 10 cases (83%) showed elevated IgG4 levels of more than 135 mg/dL and 4 cases (33%) showed elevated IgG levels of more than 1,800 mg/dL, the current cutoff value applied in Japan. Only one patient showed elevated serum IgG level, despite having normal IgG4 level. Sensitivity and specificity for AIP of elevated serum IgG4 (>135 mg/dL) were 91% and 92%, and for elevated serum IgG (>1,800 mg/dL) 67% and 92%, respectively. The optimal cut-off level of IgG4 using receiver operation characteristic (ROC) was 127 mg/dL, at which the sensitivity and specificity were 83% and 96%, respectively, for the diagnosis of AIP. Serum IgG at 1,520 mg/dL showed the sensitivity and specificity of 83% and 87%, respectively. CONCLUSONS: The measurement of serum IgG and IgG4 are helpful to diagnose AIP. Serum IgG and IgG4 are complementary to each other in the diagnosis of AIP.

Autoimmune pancreatitis is a distinct entity with characteristic morphological, histological and clinical features. Since the first report in 1961, there have been many reports on autoantibodies associated with autoimmune pancreatitis. Lymphoplasmacytic infiltration with fibrosis is the characteristic histological feature of autoimmune pancreatitis. Elevation of immunoglobulin G4 (IgG4), a subtype of IgG, can be seen in autoimmune pancreatitis. A few reports of autoimmune pancreatitis based on immunostaining of IgG4 have been published, but no reports have been published in Korea. We present here the first report of autoimmune pancreatitis, based on an increased serum IgG4 level and plasma cell infiltration that showed IgG4 positivity by immunohistochemical staining of the major papilla.
