Abstract PDF: BACKGROUND
Nitric oxide, a vasodilator synthesized from L-arginine by vascular endothelial cells. accounts for the biological activity of endothelium derived relaxing factor. Previous studies demonstrated that nitric oxide inhibitor. N'-Nitro-L-Arginine(NNA)diminished the hyperdynamic splanchnic and systemic circulation in portal hypertensive rats. The present study was done to determine the role of nitric oxide in the development of hyperdynamic circulations in the prehepatic portal hypertensive rat model produced by partial portal vein ligation. METHODS: The portal hypertensive rats were divided into water ingestion group and NNA ingestion group. After partial portal vein ligation. NNA ingestion group and water ingestion group received NNA, 1mg/kg/day and plain water through the mouth for 14 days, respectively. Cardiac output, mean arterial pressure, organ blood flow and porto-systemic shunting were measured by radioisotope microsphere methods. Vascular resistances were calculated by standard equation. RESULTS: There were significant decreases in mean arterial pressure, increases in cardiac output and cardiac index, and decreases in total systemic and splanchnic vascular resistance in portal hypertensive rats compared to normal control froup(p<0.01). Compared to the water ingestion group, significantly increased mean arterial pressure wit decreased cardiac output and cardiac index were dexeloped in the NNA ingestion group. Total systemic and splanchnic vascular resistance were significantly increased in the NNA ingestion group compared to water ingestion group(p<0.05). But, there was no significant difference in portal pressure between the two groups. CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic circulation in prehepatic portal hypertensive rat model was attenuated by ingestion of NNA. Nitric oxide may play an important role in the development of hyperdynamic circulation with splanchnic vaodilation in chronic portal hypertension.

Abstract PDF: 7 cases of acute gastric Anisakiasis have been reviewed at the Department of Internal Medicine, Yeungnam University Hospital from March, 1983 to December 1986. 1. Of 7 cases, the ratio of male and female was 3:4 and the age 30s occupied most (5 cases) the 50s' followed (2 cases). 2. Chief complains were in order of epigastric pain (6 cases), vomiting (3 cases), Nause (2 cases), Ulticaria (1 case) & epigastric fulling sensation (1 case). 3. In all 7 cases, the causative fish in astroconcer myriaster. 4. The onset of symptoms was observed within 5 to 7 hours after eating the causative raw fish. 5. Gastrofiberscopic exam was undergo within 48 hours since onset of symptoms. 6. The gastrofiberscopic findings were gastric mucosal edema and redness in all 7 cases. One case also had mucosal erosion. The involved sites of the stomach were in frequency of order, the body (5 cases), the antrum (2 cases). 7. The symptoms of the patients relieved spontaneously without medical treatment after the extraction of the larva with biopsy forcep during gastrofiberscopy. 8. In Korea, many people take raw fish and there may be many patients of Anisakiasis so if much concern and careful observation are paid to whom with severe cramping epigastric pain after taking of raw marine fish in about 10 hours, we could find out and confirm more patients suffering from Anisakiasis by immediate endoscopic gastrofiberscopy.

Abstract PDF: 159 histologically proved cases of lung cancer have been reviewed at the Department of Internal Medicine, Yeungnam University Medical School for the past two years and six months from January, 1984 to July 1986. 1. The age distribution ranged from 27 to 87 years and 69.2% of the patient were distributed between the ages of 51 and 70. 2. The ratio of male and female was 4.6 : 1 (131 males, 28 females) 3. Chief complains were in order of dyspnea, chest pain, cough, hemoptysis and weight loss. 4. Localization on chest film. Right was more than left (right 58.6%, left 36.2%) and the most frequent site is right upper lung field (33 cases, 21.7%) 6. 76.8% of case was diagnosed histologically under the bronchoscopic biopsy. 8. The most common treatment was conservative therapy In general. However chemotherapy was most common treatment of the small cell type carcinoma.
