The hemostatic effect of endoscopic microwave coagulation method for upper gastrointestinal bleeding was evaluated clinically. Hemostasis over 72 hours was achieved in 18 of 20 cases (90%) with upper gastrointestinal bleeding by the endoscopic microwave coagulation method. It is noteworthy that this method was effective in all 4 cases of pulsatile bleeding from exposed vessels. We conclude that this method is useful for emergency endoscopic hemostasis on upper gastrointestinal bleeding, especially bleeding from exposed vessels.

Hepatoma is one of the most common malignant disease among cancers that occur in Korea. Recently, according ta developing imaging diagnostic technology and non surgical treatment the hepatoma is easily detected in early diagnosis and appropriate treatment. From this point of view, the histologic pattern of hepatoma is markedly important. This is the first reported case of sclerosing hepatocellular carcinoma, which is characterized by intense fibrosis, in which the tubular neoplastic structures are embedded. The incidence of sclerosing hepatocellular carcinoma is very rare. Therefore the rare histologic pattern of hepatoma might be introduced by many studies and reports. We recently experienced a case of sclerosing hepatocellular carcinoma.

Since 1976, 938 cases of E.R.C.P. were performed at the Kwangju Christian Hospital & since December 1981, 19 cases of Endoscopic papillotomy(E.P.T.) were performed, following Results were obtained: 1) Out of 19 cases which were diagnosed by E.R.C.P.; 17 cases of C.B.D. stones, 1 case of ascaris in bile duct, 1 case of remained C.B.D. stone diagnosed by T-tube cholangiogram after operation, & E.P.T. was done in total 19 casees. 2) During 1st E.P.T., 2 cases were removed by Dormia basket under direct visualization & during 2nd E.P.T., 5 cases were removed by Dormia basket under direct visulization & 12 cases were passed in stool & 3x3.5cm large stone passage was found. 3) Complications of E.P.T. were noted in 2 cases: 1 case of bleeding was treated by blood transfusion & 1 case of Acute pancreatitis was treated by medical care.

PURPOSE: The aim of this sutdy was to evaluate the feasibility of 3-[131I]Iodo-O-methyl-L-a-methyltyrosine ([131I]OMINT) as an agent for tumor image. MATERIALS AND METHODS: After synthesis of 4-O-methyl-L-a-methyltyrosine (OMAMT), OMAMT was labeled with 131I using Iodogen method. In viro cellular uptake study was performed using 9 L gliosarcoma cells at various time points upto 4 hr. The biodistribution (five rats implanted with the 9 L gliosarcoma cells per group) was evaluated at 30 min, 2 hr, 24 hr after iv injection of 3.7 MBq [131I]OMIMT or L-3-[131I]iodo-a-methyltyrosine ([131I]IMT). Gamma camera images were obtained at 30min, 2 hr, and 24 hr. RESULTS: [131I]OMINT uptake was 3.3 times and 2.5 times higher than [131I]IMT uptake at 30 min and 60 min, respectively and same after 2 hr in in vitro sutdy using 9L gliosarcoma cells. Maximum accumulation in tumor occurred at 30 min for both [131IOMINT and [131I]IMT in tumor bearing rats. The tumor uptake of [131I]OMINT was significantly higher than that of [131I]IMT in tumor bearing rats. The tumor uptake of [131I]OMIMT was significantly higher than that of [131I]IMT at early time point studied (3.74 +/- 0.48 vs 0.38 +/- 0.17% ID/g at 30 min and 2.40 +/- 0.17 vs 0.24 +/- 0.03% ID/g at 2 hr, respectively, p<0.01). However, the tumor uptake of both radiolabels were not significantly different at 24 hr (0.04 +/- 0.01 vs 0.05 +/- 0.01% ID/g). Tumor was visualized as early as at 30 min in gamma camera images. CONCLUSION: These data suggested that [131I]OMIMT might be a useful tumor imaging agent and has more advantage for the tumor imaging compared to [131I]IMT.

Lymphangioleiomyomatosis(LAM) is a rare disease of unknown etiology that occurs mainly in woman in her reproductive age. We recently experienced two cases of bilateral diffuse cystic lesion of the lung on chest X-ray and HRCT. The first case, a 26-year-old female, who had been diagnosed with tuberous sclerosis be the presence of clinical manifestation such as mental retardation, bilateral renal angiomyolipoma, adenoma sebaceum and generalized seizure, was admitted due to recently developed hemoptysis. Chest PA showed diffuse ground-glass opacity with radiolucent cystic lesions of various sizes on both lung fields. HRCT showed innumerable small cystic lesions with suspicious diffuse ground-glass opacity on both lung fields. The second case, a 30-year-old female was admitted due to dyspnea and spewing of blood-tinged sputum for 2 weeks, shortly after delivery. Chest PA showed diffuse reticular and ground-glass opacities on both lung field. HRCT showed multiple well-difined and relatively uniform size air cysts with a uniform wall thickness on entire both lung fields, with small amount of right pleural effusion. By thoracoscopic lung biopsy she was diagnosed with pulmonary lymphangioleiomyomatosis. We report these cases with a brief review of the literatures.

The change of conditions of hydroxyapatite synthesis can affect not oniy the material properties, but also the body reaction to the hydroxyapatite implants. To find out conditions for preparing more biocompatible hydroxyapatite implants as bone graft substitute. we evaluated the biologic response to the dense synthetic hydroxyapatite implants, made with various synthetic conditions, placed in corticocancellous defects of rabbits' long bone. The hydroxyapatites were synthesized with coprecipitation technique using Ca(NO3) 4H2O and (NH4)2HPO4, made with various Ca/P ratio and aging temperatures. Four kinds of hydroxyapatites were selected to use as implants(HA I: Ca/P ratio 1.5, aging temperature 90degrees C; HA V :1.5 , 30degrees C; HA VI: 1.83, 30degrees C; and HA lX: 1.67, 30degrees C). These hydroxyapatites were pressed and sintered at l300degrees C to fabricate dense plates. Biomechanical test and rnorphological examination were performed using Instron, light microscope and electron microscope. The characteristics of hydroxyapatite powder and sintered body were more significantly affected by siarting Ca/P ratios. The bonding strength of HA IX(1.67, 30degrees C) with bone was grcatest at 4 or 8 weeks after implantation with statistically significant difference(p<0.05). Bonding behavior betweeb HA IX and bone was most excellent in terms of new bone formation and new bone ingrowth into resorbed surface of hydroxyapatite plate.

The syndrome of inappropriate ADH secretion is a disorder characterized by hyponatremia which results from water retention attributable to ADH release. The hallmark of SIADH is hyponatremia due to water retention, in the presence of urinary osmolality above plasma osmolality. The SIADH was initially described by Schwartz et al (1957). This syndrome, first recognized in patients with bronchogenic carcinoma, has now been observed in a variety of other illnesses. Recently, we encountered a 59 year-old female with small cell lung cancer, also she had SIADH. Thus, we present a case and review the literature on the subject.

Inflammatory fibroid polyp is a relatively rare, benign polyp which is composed of fibraus connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflammatory fibroid polyps has been reported with pathologic specimen in stomach and small intestine. We performed the gastrofiberscopy and endoscopic ultrasonogram of an inflammatory fibroid polyp, which reveals central ulcerated polypoid mass originated in the submucosa of antral portion of the stomach. So we report a case of endoscopic and endoscopic ultrasonographic findings of inflammatory fibroid piolyp in stomach. The etiolagy and pathology are discussed with the review of the literatures.
