Membranous glomerulonephropathy (MGN) is the most common primary cause of the nephrotic syndrome in adults, accounting for about 20% of the cases in most series. MGN is idiopathic in the majority of cases, however approximately 25% of adults have identifiable causes (secondary MGN). To evaluate the clinical and pathologic characteristics of MGN, we reviewed the clinical data and renal biopsies from 141 cases of MGN. The mean age of the patients at biopsy was 43 years old, but patients of all age were seen (range from 3 to 76 years of age). There were 88 males and 53 females. There were 99 idiopathic MGN cases and 42 secondary MGN cases. The associated causes of secondary MGN included hepatitis B infection (18 cases), SLE (10 cases), drugs (4 cases), post-transplantation MGN (5 cases), diabetes mellitus (4 cases), syphilis (1 case) and hepatitis B infection associated with rheumatoid arthritis. The prevalence of histologic stages by Ehrenreich and Churg was as follows. Stage I was 24 cases, stage II was 72 cases, stage III was 35 cases, and stage IV was 9 cases. All patients had proteinuria. Nephrotic syndrome was observed in 39%, edema in 73%, microscopic hematuria in 49%, gross hematuria in 28%, hypertension in 13%, and the serum creatinine level above 1.5 mg/dl was in 13%. Cases with glomerulosclerosis was observed in 45 cases with an increased percentage of glomerulosclerosis in the higher grade. Immunofluorescence (IF) examination showed predominantly granular IgG (118 cases) and C3 (84 cases) stainings along the glomerular capillary wall. In idiopathic MGN, sparse mesangial IF staining was noted up to 10% of the cases. However, mesangial IF staining in SLE was observed in 33%, hepatitis B infection in 28% and diabetes mellitus in 50%. An electron microscopic examination revealed subepithelial electron dense deposits of immune complex in all cases. The prevalence of mesangial and subendothelial electron dense deposit in idiopathic MGN was present in 19% and 6%, respectively. In SLE cases, mesangial and subendothelial deposits were observed in 78% and 56%, respectively. In hepatitis B infection, mesangial and subendothelial deposits were observed in 54% and 69%, respectively. In conclusion, immune deposits in the mesangium are scanty in idiopathic MGN, and if pronounced this should increase suspicion of underlying systemic diseases, such as SLE or other infectious diseases.

BACKGROUND: The extracellular matrix constitutes the dermis supporting an overlying epidermal lining. A small portion of the cell component includes fibroblasts and mast cells, a large amount of fibrous tissue as struct ural proteins, intra-and extracellular adhesive molecules, and extracellular macromolecules, glyccsarninoglycan(GAG) and proteoglycan make up the dermal connective tissue. GAGs, polysacchavide chains secreted by fibroblasts, are the main macromolecules of the extracellular matrix. GAG chains occupy large amounts of extracellular space and form hydrated gels. The various manifestations observed during the cutaneous intrinsic aging process reflect the age-related changes of dermal connective tissue. OBJECTIVE: This study was directed to observe the age-related changes of GAG in human abdominal skin without the influences of photoaeging. MaTERIALS AND METHODS: The subjects involved in this study were grouped according to the age span of 10 years. A minimum of 3 skin samples were included in each age group. After permission, three to five grams of skin samples without known underlying skin diseases were obtained from the pat,ients who were subjected to open abdominal surgery under general anesthesia. GAGs were extracted and purified by repeated cetylpyridium chloride-ethanol precipitation from each skin sample. The qualitative and quantitative analysis of GAGs was carried out with the action of specific GAG degradirig enzymes. RESULTS: The amount of GAGs per gram skin tissue decreased slowly until the 4th decade and thereafter. A statistically- significant reduction in the amount of GAGs was noted between the age groups of under 10 and that of 51-60. This pattern of decline was similar with tte change of the hyaluronic acid content in gram skin tissue. The content of chondroitin sulfate and heparan sulfate also decreased as a function of ageing. The compositional ratio of GAGs showed no age related changes. The water content measured by acetone dehydration was reduced to a significant level up to the age group of over 30 years. CONCLUSION: These results imply that the wrinkling and laxity of skin during the chronological ageing process reflect the age-related reduction of GAGs and the water content of the skin.

OBJECTIVE: The patients of endometriosis may complain of dysmenorrhea, pelvic pain, and dyspareunia, but may be asymptomatic. We studied on the correlation between the pain and the psychologic stress, Also, we studied on the correlation between serum CA-l25 levels and the psychologic stress. METHODS: The data was obtained from il7 endometriosis patients. Psychological stress was studied with STAI(Stait-Trait Anxiety Inventory) and BDI(Beck Depression Inventory). We compared the degree of anxiety and depression according to existence of pain and the duration of pain. Also we examed the scores of STAI and BDI according to the level of serum CA-125. RESULTS: The pain group had more depression and anxiety, in comparison to the pain-free group. And the depression and anxiety significantly increased in long-term pain group. There was no correlation between the level of serum CA-125 and the depression,or axiety. CONCLUSION: The pain of endometriosis may play a role of pychological stress to the patients, so it seems to increase depression and anxiety.

PURPOSE: We investigated the role of myocardial perfusion SPECT in prediction of ventricular dilatation and the role of revascularization including thrombolytic therapy and PTCA in prevention of ventricular dilatation after an acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress, 4 hour redistribution, and 24 hour reinjection Tl-201 SPECT in 16 patients with AMI two to nine days after attack. Perfusion and wall motion abnormalities were quantified by perfusion index (PI) and wall motion index (WMI). Left ventricular ejection fraction (LVEF), WMI and ventricular volume were measured within 1 week of AMI and after average of 6 months. According to serial changes of left ventricular end-diastolic volume (LVEDV), patients were divided into two groups. We compared WMI, PI and LVEF between the two groups. Relationships among degree of volume, stress-rest PI, WMI, CKMB, Q wave, LVEF and revascularization were analysed using multivariate analysis. RESULTS: Only initial rest perfusion index was significantly different between the two groups (p<0.05). While initial LVEF, stress PI, CKMB, trial of revascularization procedure, presence of Q wave and WMI were not significantly different between the two groups. Eight of 16 patients (50%) showed LV dilatation on follow-up echocardiography. Three of 3 patients (100%) who did not undergo revascualrization procedure documented LV dilatation. And only 5 (38%) of the remaining 13 patients who underwent revascularization revealed LV dilatation. There was no difference in infarct location between the two groups. By multivariate linear regression analysis in patients only undergoing revascularization, rest perfusion index was the only significant factor. CONCLUSION: Myocardial perfusion SPECT performed prior to revascularization was useful in prediction of LV dilatation after an AMI. Rest perfusion index on myocardial perfusion plays as a significant predictor of left ventricular dilatation after AMI. And revascularization appears to be a valuable procedure in alleviating LV dilatation after AMI with or without viable myocardium in a limited number of patients studied retrospectively.

Lymphangiectasis(=acquirecl lymphangioma) ate dilated lymph caillaris and may be due to the obstruction of the lymphatic circulation from surgery, irradiation, chronic recurrent infection or trauma. The patient was a 5 years old girl who developed a straw-colcre, asymptomatic grouped vesicular mass resembling frog spawn measuring 9 cm in diameter the left axilla and arm, 2 months after the total excision of a previous lymphangiectatic mass. She had a history of previous open heart surgery at 2 years of age. Histopathologic findings showed large, irregularly shaped cysticalation lined by a single layer of endothelium in the superficial dermis. Immunohistochemical stainig showed vimentin positive and negative results in Factor VIII and HLA-DR antigen which was compatible with a lymphatic vessel.

Reiters syndrome is classically described as the triad of urethritis, coijuctivitis, and arthritis along with the skin manifestation. of keratodermia blenorrhagica, circinate b lanitis and oral ulcetation. Since arthritis is now recognized as the only consistent component, iricr nplete forms consisting of characteristic arthritis associeited with one or more of these features and of dysentery are common, We reported a 48-year-old male who presented with a 3 years histor of significant arthralgia and psoriasiforrn skin involvemeni. He had neither an episode of dysentery not, history of sexual exposure before the onset of symptomes. Showed a correlation with the HLAB 7 tialotype. C-reactive protein levels were significantly elevated. He was treared with corticosteroid, pcycline, methotrexate and indomethacin for about 3 months resulting favorable improvement.
