Tumors of neurogenic origin are rare and constitute.about 496 of all tumors found i the stamach. Neurilemoma (schwannoma, neuroma) and neurofibroma are the most prevalent. Gastrointestinal symptoms of neurogenic tumors result from obstruction or bleeding. A 57-year-old female presented with epigastric pain for 9 months. UGI series and ahdominal CT showed a submucosal tumor at gastric fundus. Endoscopic exam revealed submucosal tumor with central ulceyation and bridging folds. Microscopic exam of endoscopic biopsy suggested neurilemoma. Local tumor excision was performed. The nerve origin of this tumor was confirmed by positive staining of histchemical study with S-100 protein and by demonstrating Schwann cells with long cytoplasmic processes. on electron microscopic study. The finaI histologic diagnosis was neurilemoma. So we reprot a case with a review of relevant literatures.

N/A The effect of short-term levamisole therapy on serum ferritin and E-rosette forming lymphocytes was studied in 29 patients with various malignant tumors. And 8 normal person. In patients with malignant tumors, active form of T-lymphocytes were more decreased than total form of T-lymphocytes and serum ferritin was significantly increased. Levamisole had a moderate enhancing effect on E-rosette formation in patients with malignant tumors. These effect was more prominent in total form of T-lymphocytes than active form of T-lymphocytes, which suggested that active form of T-lymphocytes were more seriously affected than total form of T-lymphocytes and former may be more important in cellmediated immunity of the malignant patients. Serum ferritin was decreased in average 22% after levamisole therapy, but none of cases reduced to normal range in patients with significantly elevated serum ferritin level. There was close correlation(r=0.51) between decrease in serum ferritin and enhancing effect on E-rosette formation in malignant tumors after short-term levamisole therapy. These results indicate that levamisole as a role of immunotherapy may be beneficial in patients with malignant tumors.

Hemorrhage is an uncommon but serious cornplicaticm of pancreatic pseudocysts. When gastrointestinal bleeding or intra-abdominal hemorrhage is associated with a pancreatic pseudocyst and the usual sources of bleeding are not detected by endoscopy, the rupture of a pseudoaneurysm inside the pseudocyst should be suspeeted. We report four cases presenting with major bleeding. Bleeding was massive in two patients and intermittent in two. It resulted from erosion of the gastroduodenal artery in two patients, bleeding into the pancreatic duct in one patient, erosion of the duodenum by a bleeding pseudocyst in one and involvement of the spleen by a bleeding pseudocyst in one. Of the four patients with bleeding pseudocysts, two underwent primary pancreatic reseetion and the other two underwent transcatheter embolization with embolus coiL Bleeding was successfully controlled by the transcatheter arterial embolization in one out of the two patient and pancreatic resection was performed in the rest of three patients.

N/A Of the many hepatic enzymes, only a few are generally used for diagnosis of liver disease. Alkaline phosphatase and aminotransferases are example of two differnet groups of enzymes providing information about pathologic conditions. Aminotransferase reflects hepatic cellular injury with sorbital dehydrogenase and 5-lactic dehydrogenase. Alkaline phosphatase refrects cholestasis and its activity can easily be corrected with that of other enzymes like leucine- aminopepeptidase and 5-nucleotidase. Enzymes indicating alterations of the liver, but not belonging to one of those groups mentioned, include gamma-glutamyl transpeptidase(r-GTP), which was introduced as a test of liver function by Polish authors to indicate chronic hepatitis. A special feature of this enzyme is its increasement with prolonged intake of some drugs or alcohol. This enzyme has been used for differentiating viral hepatitis from obstructive jaundice mainly correlating SGOT or SGPT with r-GTP. Later, r-GTP was not only recommended as an indicator of minor alterations of the liver but also it was introduced as a most sensitive test for alcoholic hepatic cellular injury. The SGOT/SGPT ratio is used as an indicator of minor viral hepatitis and alcoholic induced liver injury. It should be due to the different location in the hepatocyte of the enzyme, as SGPT is present free at cytosol, whereas SGOT is demonstrable at mitochondria and cytosol in hepatocyte. r-GTP in the liver is found in hepatocyte and small bile ductules. The enzyme can be detect by enzyme histochemical methods in hepatocyte and by cytochemical techniques bound to membranes and microsomes. So the observations of SGOT/SGPT, SGOT/r-GTP and r-GTP/SGPT in various hepatic diseases concurrently might be helpful for making the differential diagnosis of the hepatic diseases. So we have observed the ratios of the enzyme activities, SGOT/SGPT, SGOT/r-GTP and r-GTP/SGPT in 20 cases of control group and 130 cases of various hepatic diseases group (Male 107, Female 42), which is including 25 cases of acute viral hepatitis(A.V.H.: Male )9, Female 8 ), 17 cases of chronic active hepatitis(C.A.H.: Male 9, Female 8.), )14cases of chronic persistent hepatitis(C.P.H.: Male 10, Female 4), 14 cases of liver cirrhosis(Male 34, Female 6), 20 cases of primary hepatocellular carcinoma(Male 16, Female 4. ), 8 cases of liver abscess(Male 4, Female 4,) and 12 cases of gall stone(Male 5, Female,7) The results were as follows: 1) In normal control group, the SGOT/SGPT is l.76+- 0.44, SGOT/r-GTP 1.20+-0.67 and r-GTP/SGPT 1, 931+-l. 14 The activity of alkaline phosphatase is 2.6+-0.6 Bessey-Lowry unit 2) In A.V.H. group, the SGOT/SGPT is 0. 78+-0.46, SGOT/r-GTP 3. 46+-2.36 and r-GTP/ SGPT 0.47+-0.91. The ratio af the SGOT/SGPT and r-GPT/SGPT are decreased significantly than the nor mal(p(0.005, p(0.005), but the SGOT/r-GTP is increased significantly, 2.5 times than the normal(p(0.005) It were helpful for differentiating A.V.H. for the other hepatic diseases 3) In C.A.H. group, the SGOT/SGPT is 0. 7+-0.35, SGOT/r-GPT is 1. 63+-1.23 and r-GTP/ SGPT is l.76+-1.38. The each ratio of SGOT/r-GTP and SGPT/SGPT is slightly increased and decreased than the normal(p=0.10, p<0.05) The SGOT/SGPT ratio was markedly decreased. It was helpful for the differentiation of the C.A.H. from the other hepatic diseases. In cirrhosis of liver group, the SGOT/SGPT is 2.05+0.88, SGOT/r-GTP is 1.27+-1.59 and r-GTP/SGPT is 2.97+-2.48. All of the ratios were increased slightly with mild elevation of the alkaline phosphatase activity. It svas also helpful for differential diagnosis of the liver diseases. 5) In primary hepatocellular carcinoma, The SGOT/SGPT is 1.82+-0.97, SGOT/r-GTP is 0.49+-0.29 and r-GTP/SGPT is 5.02+-3.80,The alkaline phosphatase activity was elevated over 2.5 times than the normal as 7.2+-5.2 Bessey-Lowry unit. With the marked elevation of r-GTP/SGPT ratio and alkaline phosphatase activity, the markedly decreased ratio of SGOT/r-GTP were

N/A The biological characteristics and the genesis of gastric carcinoma, the most common malignancy in Korean adult male, have not been established so far. Estrogen receptors (ER) have been idnetified in many hormone-dependent cancer such as breast cancer, prostate cancer and ovarian cancer and utilized clinically to provide hormonal therapeutic manipulation. In order to find any hormonal relation in gastric cancer, the presence of ER was examined in 38 patients with primary gastric carcinoma, six with benign stomach lesions and 17 normal gastric tissues, using monoclonal antibody by enzyme immunoassay in cystosol. The results obtained were as follows; 1) ER concetration (Mean+SD) in cytosol from noraml gastric tissue, benign gastric lesion and gastric cancer tissue were 5.6+4.6, 14.617.7 and 20.1+41.7 fmol/mg protein, respectively. Positivities of ER in normal gastric tissue, benign gastric lesion and gastric cancer tissue were 0, 16.7 and 21.1%, respectively. Concentration and positivity of ER were higher in gastric cancer tissue, especially in female gastric cancer tissue, than noraml gastric tissue and benign gastric lesion. 2) Highest value of ER concentration and ER posiitvity according to the macroscopic classification of the gastric carcinoma was observed in Borrmann type II. There was an increasing tendency in ER positivity as the size of the cancer increase. 3) ER concentration and positivity according to the histologic pattern were higher in poorly and well differentiated tubular adenocarcinoma than mucinous adenocarcinomas, signet ring cell carcinoma and moderately differentiated tubular adenocarcinomas. 4) Concentration and postitivity of ER from cancerous tissue of the postmenopausal patients were more higher than that of the premenopausal patients. These results suggested that there was close reation between the presence of ER and the evolution of gastric carcinoma, but not with the degree of histologic malignancy.

N/A A potent oral protease inhibitor, Camostat Mesilate (FOIPAN), was developed for the therapeutic agent in chronic pancreatitis. The clinical effects were evaluated in 25 patiented with chronic pancreatitis. 200 mg of FOIPAN' was given t.i.d. orally for 4 weeks. FOIPAN was very effective in the alleviation of the suhjective symptoms such as abdomilial pain, nausea and vomiting, indigestion and abdominal full#oess#. The global utility rate of the FOIPAN in the chronic pancreatitis was 76.0%. It was most effective in the patients with elevated serum amylase level. There were no significant side effects during the clinical trial. It could be said that FOIPAN was a safe and effective drug in the treatment of chronic pancreatitis.

N/A Bile duct carcinoma is relatively rare malignancy with an extremely grave prognosis. The case records of 49 patients with primary carcinoma of the bile ducts seen at the Chonnam University Hospital from 1981 to 1988 were reviewed and analyzed. The results were as fo]lows 1) The peak age distribution was in seventh decade and the average age being 61.4 years. The sex ratio of male to female was 1.9:l. 2) In 43 of the 49 patients, anatomic location was extrahepatic bile duct. The most frequently involved site among the extrahepatic bile ducts was common bile duct (38.8%). 3) The most common symptom and sign were RUQ abdominal pain (75.5%), jaundice (89.7%), respectively. 4) Serum alkaline phosphatase and r-GTP were more increased in extrahepatic bile duct carcinoma than intrahepatic bile duct carcinoma. 5) Associated disease were clonorchiasis (12.2%), choledocholithiasis (10.2%), and gall stone (4.0%). 6) The most useful diagnostic modality was percutaneous transhepatic cholangiography and focal stenotic lesions (66.6%) were rnost common. 7) Operability and resectability were 26.5%, 16.3%, respectively. 8) Tubular adenocarcinoma was the most frequent histo]ogic type.
