The usefulness of E-cadherin immunostaining as a marker of malignancy in the body fluids was investigated in the present study. Thirty-three histologically proven cases of cell blocks from the pleural, peritoneal, and pericardial fluids were studied by immunocytochemistry for E-cadherin antibody using LSAB method. These cases were cytologically diagnosed as adenocarcinoma (25 cases) and atypical cells (8 cases). Tumor cells showed strong positive membranous staining for E-cadherin antibody in 21 out of 25 cases (84%) of adenocarcinoma. E-cadherin staining was not found in 6 of 8 cases of suspicious maligancy. The sensitivity and specificity were 84% and 75%, respectively. Reactive mesothelial cells and inflammatory cells scattered were all negative. In conclusion, E-cadherin is an useful adjunctive marker to distinguish reactive mesothelial cells from the carcinoma cells in the body fluids.

PURPOSE: Norepinephrine has modulatory effects on neuronal excitability and, in some cases, has a proconvulsant effect. Intraperitoneal imipramine treatment increases norepinephrine level, and to a lesser extent, dopamine and serotonin in brain dialysate from rats. We sought to determine the effects of imipramine on pilocarpine-induced seizures in the immature rats. METHODS: Right and left cortical and hippocampal electrodes were placed in 10~15 day old Sprague-Dawley rats. The following day 3-hour video EEG recordings were obtained to monitor electrographic seizures and status epilepticus induced by intraperitoneal injection of high dose(200mg/kg : HD) and low dose (75mg/kg : LD) pilocarpine. A first group of rats received HD pilocarpine alone(n=25), or pretreatment with 0.5(n=6). 1(n=6), 2(n=6), 5(n=6), or 10(n=11)mg/kg of imipramine. A second group of rats received LD pilocarpine alone(n=6) or pretreatment with 2mg/kg of imipramine (n=6). Data were analyzed using the Fisher exact test. RESULTS: Treatment with HD pilocarpine alone resulted in electrographic seizures in 76%(n=19) and status epilepticus in 44%(n=11). In the HD pilocarpine group, status epilepticus was seen in 100% of rats pretreated 1, 2, and 5mg/kg imipramine. 90.9% of the rats pretreated with 10mg/kg of imipramine developed seizures and 36.4% developed status epilepticus. Imipramine at 0.5, 1,2, and 5mg/kg increased the incidence of seizures and status epilepticus in the HD pilocarpine group, but the incidence was statistically significant only for status epilepticus(p<0.05). The latency for the occurrence of first status epilepticus was 12.3+/-1.3 min in the HD pilocarpine alone group, and it was 21+/-3.8 min and 25.3+/-5.7 min in the group pretreated with 5 and 10mg/kg imipramine, respectively(p<0.02). Treatment with LD pilocarpine alone resulted in seizures in 50% and status epilepticus in 16.7%. In the LD pilocarpine group with imipramine 2mg/kg pretreatment, 83.3% had seizures and status epilepticus. Imipramine at 2mg/kg increased the incidence of seizures and status epilepticus in the LD pilocarpine group, but the increase was statistically significant only for status epilepticus(p<0.05). CONCLUSION: Imipramine exhibits a proconvulsant effect at low doses and an anticonvulsant effect at high doses in the pilocarpine seizure model in immature rats. There may be a dose-dependent effect on monoaminergic receptors which results in increased neuronal excitability.

Osteogenesis imperfecta is a heterogenous group of inherited disorder, which has abnormalities in the synthesis of collagen. Among variable clinical manifestations, orthopaedic clinical features are laxity of ligament and deformities arising from frequent fractures or angulation due to skeletal fragility. We had managed 4 cases of osteogensis imperfecta, which were belonged to type IV-B in two cases, type I-A in one, and type I-B in remained one by Sillence classification and they had suffered from recent fractures or deformities due to previous fractures in the long bones of the lower extremities. These patients had been treated with various types of intramedullary nails, such as Bailey-Dubow extensile rod. Rush rod and Kuntcher nail, and the result of intramedullary nailing lead to improvement of walking ability.

Eight men with a one-ta-seven-year history of rosacea which poorly controlled by oral tetracycline or metronidazole, with or without topical medications, were given 13-cis-retinoic acid in dosages of p.5 to 0. 7 mg/kg/day for eight weeks. The size of erytherna and the number of papules had been gradually decreased since the second week of treatment. Eight weeks later more than 75p, regression was recognized in six patients, however telangiectasia remained unchanged. All eight patients complained of only mild degrees of cheilitis and dryness of the nose, and had no evidence of the serologic abnormalities on the tests examined during the period of therapy.

Intra- and extrahepatic bile duct can be invaded by hepatocellular carcinoma (HCC). This is infrequent in HCC, but it can directly affect the clinical manifestation and prognosis. We present eight cases of HCCs with emphasis on the incidence and features of bile duct invassion on computed tomography (CT). Over a period of 22 months, abdominal CT was performed in 186 with HCC patients. Out of these, five cases of bile duct invasion by HCC were confirmed in our hospital and three in other hospitals. The eight cases were evaluated for the type, size and location. CT features of intraductal mass and ductal dilatation were evaluated. The incidence of bile duct invasion in HCC was 2.6%. Infiltrative type of HCC was seen in seven cases and six of these had mass 5-11 cm in size. The characteristic CT findings of bile duct invasion in HCC are mass in common hepatic duct with bulging contour(8/80, multiple intraductal masses in the intrahepatic ducts (5/8), and diffuse dilatation of intrahepatic ducts (7/8).
