Pararenal pseudocyst is a collection of fluid within the renal fascia outside the renal capsule and a relatively rare clinical entity which commonly occur as a result of trauma. either accidental or operative. Histologically, the wall is composed mostly of dense collagenous fibrous connective tissue. with no cellular elements capable of cyst formation. A case of pararenal pseudocyst associated with renal hypertension developed in 6 year-old boy after blunt abdominal trauma was reported.

Cavernous hemangioma of the bladder is the rarest of all bladder tumors. Less than 75 cases were reported in the literatures since Broca reported the first case in 1869. We report a case of cavernous hemangioma of the bladder in a 7-year-old girl and literatures were reviewed.

Peritoneal mesothelioma is a rare disease which arises from the mesothelial lining cells in the peritoneum and spreads to the peritoneal wall, omentum and other abdomina1 organs. Aabestos is one etiologic factor and the other factors are genetic cause, radiation, exposure to toxic materials and recurrent yeritonitis. We experienced a case of multiple small nodular peritoneal mesothelioma after exposure to asbestos for over 20 years. He was a sailor and had worked in the engine department of the ship, in which he wrapped up the pipe of engine in asbestos. This person came to our hospital because of inconvenience due to a distended abdomen. Tumor markers were all within normal limits and there was no evidence of tuberculosis in the abdomen and chest. The CT findings of the abdomen were as follows: There was abundant ascites in the abdominal cavity and multiple small nodules on the parietal peritoneum and especially on the lower abdomen. The omentum thickened diffusely. It was difficult to distinguish from peritoneal mesothelioma and peritoneal carcinomatosis or intestinal tuberculosis. The laparoscopic findings were as follows: There were multiple small nodules on the parietal peritoneum and omentum. The small nodules were a gray white color and uneven compared to tuberculous peritonitis. Therefore, we observed the malignant mesothelial cells by means of the light microscope and electron microscope and concluded that this case was peritoneal mesothelioma.

Effect of acute carbon monoxide poisoning on prostatic acid phosphatase in white rat hag been studied histochemically. The experimental animals were exposed to 0.25% and O. 5% of carbon monoxide from 5 minutes to 4 hours duration. Gomori's modified method was used for acid phosphatase test. Following results are obtained: 1. The acid phosphatase activity increases after 30minutes of exposure in both experimental groups, 0.25% and 0.5% of carbon monoxide, and the changes of acid phosphatase activity become more significant according to the duration of exposure. 2. The changes of acid phosphatase activity are similar in both experimental groups exposed to 0.25% and 0.5% of carbon monoxide. 3. No significant histopathological changes are observed in rat prostate gland.

BACKGROUND: We evaluated 1) the sequential changes of angiotensin-converting enzyme (ACE) mRNA expression in lung (main site for circulating ACE synthesis) and left ventricle, and 2) whether such expression is modified by ACE inhibitor or angiotensin II receptor blocker treatment after acute myocardial infarction (MI) in rats. METHODS: Placebo, captopril (2 g/liter drinking water) or TCV-116 (10 mg/kg/day gavage) was administered 3 days before left coronary occlusion and continued for 6 weeks. At 1, 3 and 6 weeks after operation, hemodynamic measurement was performed and pulmonary and myocardial ACE mRNA expression was analyzed by quantitative RT-PCR using rcRNA as an internal standard. RESULTS: Mean BP and LVEDP increased in untreated rats compared with captopril- and TCV-116-treated rats (post-MI 6week, p<0.05). Pulmonary ACE mRNA increased in acute phase (post-MI 1 week, max. 1.4 fold, p<0.05 vs. pre-MI) and returned to pre-MI value thereafter. In contrast, cardiac ACE mRNA expression showed slightly decreasing tendency in acute phase, and was increased up to 1.6 fold in chronic phase after MI (post-MI 3 and 6weeks, p<0.05 vs. pre-MI). No changes in pulmonary ACE gene expression were found with RAS blockade. However, in acute phase after MI, cardiac ACE mRNA increased with both captopril and TCV-116 treatment (post-MI 24hour and 1week, max. 2 fold, p<0.05 vs. untreated group). CONCLUSION: 1) In contrast to the pulmonary ACE mRNA that is activated in acute phase, the cardiac ACE mRNA is activated in chronic phase after MI. 2) RAS blockade does not affect the change of pulmonary ACE expression, but modulate the change of cardiac ACE expression after MI.

BACKGROUND: Chronic cutaneous lupus erythematosus(CCLE) is a well-known disease entity. But there has been no data about its clinical behavior and histopathologic features in Korea. OBJECTIVES: This study was conducted to elucidate the clinical, laboratory, and histopathologic features of CCLE, and the relationship between CCLE and SLE. MATERIALS AND METHODS: We investigated 48 cases of CCLE that visited the department of dermatology at the Seoul National University Hospital from January 1990 to June 1997. Medical records and biopsy slides were reviewed.

The bladder neck contracture is not uncommon in children and adult. The etiology remains controversial despite extensive studies, however it is usually accepted that bladder neck contracture is congenital in children and is due to previous lower urogenital infections in most of adult males. In spite of various modalities of treatment its high recurrence rate has been a perplexing problem. During the period from January 1, 1973 to December 31, 1976, 90 cases of adult male bladder neck contractures were studied clinically. Transurethral vesical neck resection was performed on 15 cases and phenoxybenzamine treatment was taken on 9 cases. The following results were obtained. 1) The age range of the patients in this study was from 17 to 79 years. 27.8% of the cases were between 30 and 39 years old and the most patients of group III were observed beyond 40 years of age. 2) The patients of group III usually has longer history of symptoms than group I and II patients. 55.6% of the cases had the onset of one year to 5 years. 3) Analysis of the 90 cases shows that common urinary symptoms were frequency(70%), diminished and weak stream(66.7%) and tenesmus(44.4%). 4) 88% of the cases was associated with the one or more diseases of chronic prostatitis, posterior urethritis or verumontanitis. 5) The bladder trabeculation was the most common finding(91.1%). In 73.3% of the cases interureteric ridge was elevated. Vesical outlet was narrowed as reversed V shape in almost all cases. 6) In 68.8% of the cases urine findings was normal, Pyuria was observed in 20% and microscopic hematuria in 16.6%. 7) Transurethral vesical neck resection was performed in 15 cases; All preoperative symptoms were relieved in 10 cases, but no improvement was observed in 5 cases. 8) 9 cases were treated with sympatholytic drug, phenoxybenzamine and significant improvement of all obstructive symptoms was obtained after 10 days or 2 weeks of treatment in all cases.
