Glomus tumors are maturely organized proliferations of glomus cells and vascular channels. Such tumors are rare in the stomach, and only two cases have been reported in Korea. Because specific clinical or radiologic features are not associated with the glomus tumor, it can be recognized only by histologic characteristics. Although available data are inadequate for determining the histogenesis of this tumor, it may represent a hamartoma rather than a neoplastic disease. The treatment of choice is local resection. In frozen sections, it may be misidentified as a carcinoid tumor, leading to more extensive surgery than required for cure. We report a case of a glomus tumor of the stomach in a 30-year-old female patient who was operated on, and we present a review of the literature on this subject.

PURPOSE: To analyse the parameters of in vivo pharmacokinetics such as absorption, distributionin , and excretion of adriamycin patients with hepatocellular carcinoma, and investigate the stagnation of adriamycin, in the liver. MATERIALS AND METHODS: Five patients in whom hepatocellular carcinoma was diagnosed and who were admitted for transhepatic chemoembolization were involved in this study. Fifty mg of adriamycin was mixed with 2.5 mL of water-soluble contrast material and 12 -15 mL of lipiodol, and the emulsion was injected into a selected tumor-supplying artery using a 3-F catheter. Between 1 minute and 72 hours after chemoembolization, peripheral blood samples were then obtained, and from these the blood concentration curve of adriamycin was calculated and applied to a two-compartment model. Using the model, several pharmacokinetic parameters were estimated. RESULTS: The volume of the central and the peripheral compartment was 45 L and 4090.6 L, respectively. 75.14% of adriamycin was delivered to the liver directly, and the absorption rate constant was 2.448/hr. Distribution clearance was 969.3 L/hr, and excretion and metabolic clearance was 136.4 L/hr. CONCLUSION: Using a two-compartment model, the in vivo pharmacokinetics of adriamycin after hepatic arterial chemoembolization were successfully analyzed. On the basis of the parameters determined, it may be concluded that in these five patients, adriamycin remained in the liver in much greater quantities and for longer.

A clinical and radiological study was done on 96 cases of spontaneous pneumothorax, encoutered in the Dept. ofRadiology, Busan National University Hospital during last 3 years from March. 1979 to March 1982. The results weresummarized as follows; 1. In the age distribution, the ages between 20 and 39 years were most highest, as 54 cases(56.3%). In the sex distribution, the ratio of male to female was 5:1 in male predominance. 2. The underlyingpathology of the total 96 cases of spontaneous pneumothorax were of tuberculous origin in 33.3% andnon-tuberculous origin in 66.7%. And below 20 years, most were of non-tuberculous origin. 3. In the cases of lungcollapse over 2/3, non-tuberculous origin was more than tuberculous origin and had characteristics of significantmediastinal shifting, in contrast to lower percentage of fluid level by chest radiography. 4. The rupture of blebsor bullae was the main immediate causes of spontaneous pneumothorax, independent of the underlying pathology. 5.In only 27 cases (28.1%) among total 96 cases, bullae or blebs could be detected on the chest radiography. 6. Intreatment of spontaneous pneumothorax, the closed thoracotomy with under water seal drainage is accepted to be thegeneral method of treatment. But open thoracotomy is considered as the best useful therapeutic procedure toprevent the recurrence, whenever bullae of blebs are found on the chest radiography. 7. In the cases of closedthoracotomy, the recurrent rate was 25.0% and most cases were found at the ipsilateral side of the first attack.8. Within a week, the collpased lung were well expanded in most cases of total 96 cases, after closed thoracotomy.

Hepatocyte growth factor (HGF) is a glycoprotein secreted from stromal fibroblasts which bind to the transmembrane Met receptor. This receptor is expressed from a variety of tumors, including gastric carcinomas. To look for a possible paracrine loop between gastric cancer cells and their surrounding fibroblasts in a gastric carcinoma, the effect of HGF on the morphology and expression of the cell- adhesion molecule E-cadherin was examined using fifty resected gastric carcinomas. The expression of Met and E-cadherin in primary gastric carcinoma was examined using immunohistochemical staining. The level of HGF in the tumor extracts was determined by using an Immunis HGF EIA kit (Institute of Immunology). The levels of HGF in the tumor extracts correlated significantly with the progression of the tumor stage (p<0.05). The mean level of HGF was significantly higher in the tumors of an undifferentiated type than in those of a differentiated type (p<0.05). Eighty-two percent (82%) of the tumors showed increased Met expression, but no significant correlation was found between Met expression and tumor progression or differentiation. Twenty-six (52%) tumors revealed a preserved E-cadherin expression similar to that of a normal gastric mucosa. Abnormal E-cadherin expression was found in twenty-four tumors (48%). There was a significant correlation between the degree of E-cadherin expression and the progression and differentiation of the tumor. The level of HGF in a tumor with cytoplasmic E-cadherin expression was significantly higher than that with membranous E-cadherin expression. In conclusion : we can conclude that HGF has the ability to modulate E-cadherin expression and induce intracellular translocation of E-cadherin in gastric carcinomas.

The term, bilateral segmental neurofibromatosis had been used to refer to patients who had unilateral neurofibromas with contralateral pigmented lesions or bilateral neurofibromas. Partial unilateral lentiginosis is characterized by numerous lentigines localized to a body segment. The coexistence of bilateral neurofibromas and partial unilateral lentiginosis raises the possibility that partial unilateral lentiginosis could be a variant of segmental neurofibromatosis. Nevus of Ota arise from dermal melanocytes and it can be associated with neurofibromatosis. A 60-year-old man presented with bilateral segmental neurofibromatosis with partial unilateral lentiginosis on the right arm and right leg, nevus of Ota on right forehead, and one cafe-au-lait spot on the abdomen.

Heterotopia (of Ectopia) is defined as the occurrence of normal tissue in an abnormal location. Heterotopic gastric mucosa has been found throughout the length of the gastrointestinal tract from oral cavity to the rectum. Curiously, it is extremely rare in the gailbladder, but when it occurs, it tends to cause symptoms of acute cholecystitis in patients under 20 years of age, and chronic cholecystitis and gallstones in older patients. The heterotopic mucosa results in an intramural mass, a polyp or multiloculated gallbladder. A firm diagnosis of gastric heterotopia is based on the presence of fundic or pyrolic mucosa replete with parietal and chief cells. A clear distinction from intestinal rnetaplasia should be made, but at times may be difficult. Potential complications include mucosal ulceration, obstruction, and hemorrhage. Treatment is cholecystectomy. We report a case of gastric heterotopia in the gallbladder of a 35-year-old-man. Ultrasonography showed fatty change of liver with a 1.5 cm-sized polypoid lesion in the gallbladder. Endoscopic retrograde cholangiography showed a small filling defect, revealed by pooling of the dye in the center, in the body of gallbladder. Laparoscopic cholecystectomy was performed. A sessile polypoid leision with central umbilication was seen in the upper body of gallbladder, without gallstones. The microscopic finding of polypoid lesion consisted of gastric pyloric glands with parietal and chief cells. The surrounding mucosa revealed ordinary gallbladder epithelium without any metaplastic change. We report a case of this condition in which there was a separate loculus lined by gastric epithelium.

We studied the effect of 1% apraclonidine (Iopidine(R)) on the ocular hypotensive action and its ocular side effects following laser surgery for glaucoma. One hundred twenty patients with primary angle closure glaucoma underwent argon laser peripheral iridotomy and 40 patients with primary open angle glaucoma were treated with laser trabeculoplasty. Mean lOP of eyes instilled with 1% apraclonidine fell by 16% 3 hours after instillation in laser iridotomy cases and by 28% 3 hours after instillation in trabeculoplasty cases. lOP elevation greater than lO mmHg was found in 18 eyes (30%) of the control group in iridotomy cases and 4 eyes (40%) in trabeculoplasty cases, but none in the apraclonidine group in both treated cases for the first three hours. Apraclonidine reduced the incidence and magnitude of potentially harmful lOP elevations after laser irdotomy and trabeculoplasty.

PURPOSE: This investigation was to evaluate the efficacy of catheter-directed thrombolysis with urokinase in treating symptomatic deep vein thrombosis (DVT). METHODS: Eight patients with DVT underwent treatment for 8 affected limbs. The average urokinase dose was 487.5 million IU (range, 1.5 million to 6.5 million IU) infused over an average of 48 hour (range 24~72 hours). RESULTS: Lysis was complete in 5 (63%), and partial in 2 (25%), not achieved in 1 (12%). One chronically occluded proximal iliac vein through popliteal vein antegradely and tibial vein through internal jugular vein retrogradely could not be crossed with a guide wire. Angioplasty (n=3) and stent placement (n=1) were applied in three limbs with underlying venous stenosis. One limb among three limb of initial complete lysis was detected thrombus at femoral vein but this patient was asymptomatic at 6 month later. There were no major complications or clinically detectable pulmonary emboli. CONCLUSION: This initial experience suggests that catheter-directed thrombolysis with urokinase for treatment of symptomatic DVT is safe and effective.
