The positive rate for serum anti-Hbs was analized among 424 0f HA vaccinated and 2035 of non-vaccinated cases at the Yeungnam University Hospital, Computed Automated Med-screening Center. Most of them from Kyungbook province and they had the last HB vaccination in the periods of 3 to 42months prior to this study. The followings were obtained. 1. The positive rates for serum HBsAg were 0.7% in the vaccinees, 9.6% in the non-vaccinated and 8.0% in the whole cases. 2. The positive rates for serum ant-HBs were 66.3% in the vaccinees, 47.9% in the non-vaccinated and 51.6% in the whole cases. 3. The positive rates for serum anti-HBs were 51.4% in the cases with one time of vaccination and 68.6% in the cases with two times of vaccination. On the vasis of these findings the positive rate for serum anti-HBs among the vaccines was significantly higher than of non-vaccinated (P<0.05). The positive rate for serum anti-HBs shortly after vaccination was higher than that of present our study which was made relatively long period after vaccination. As the reason a natural decrease of the titers of the serum anti-HBs can be postulated as one of the contributing factors for the discrepancy. In order to keep to serum antibody of perfect protectivity against HBV, it may be better to check the serum anti-HBs just vaccination, follow up and take booster injection when it is needed.

In recent years, an increasing number of drugs have been reported to cause direct esophageal damage. More than 30 cases on tetracyclines induced esophageal ulcer have been reported since the first description of tetracycline induced esophageal ulcer by Bokey and Hugh in 1975. In Korea, only one case of doxycycline-unduced esophageal ulcer has been reported. Authors have experienced 3 cases of esophageal ulcer probably caused by tetracyclines. The patients had taken their capsules just before going to bed with little fluid intake. About 6-8 hours later they had felt substernal burning sensation and epigastric discomfort. Gastrofiberscopy revealed relatively well demarcated circular ulcers on the mid esophagus. An esophagogram showed no apparent abnormality. Patients's symptoms became negligible with antacid treatment within 2-5 days. One of the causes of the esophageal ulcer is thought to be the delay in transit time of drugs and direct esophageal damage from mucosal contact when tablets are ingested in the recumbent position without an accompanying proper quantity of fluid. If only physicians endow patients with more concern about drug induced esophageal ulcer, they could find out more increasing number of drug induced esophageal ulcers by gastroscopic examination and thereby could prevent tetracycline induced esophageal ulcer.

Ulcerative colitis is diffuse inflammatory condition at mucosal lining of the colon & rectum and rare in Korea but there are no pathognomonic features or specific diagnostic tests. However, recently the diagnostic methods for ulcerative colitis are much developed and the incidence of ulcerative colitis is increased in Korea. Therefor, an analysis of 31 cases of ulcerative colitis which was diagnosed and treated in the department of the YeungNam University Hospital from May l983 to April 1991 was reviewed. The results were as following: 1) The sex distribution assumed a ratio of 1 to 2.1 and the age distribution was vqriable but the most prevalent age group was 5th decade(29.0%). 2) The most common clinical manifestations were abdominal pain & bloody diarrhea. 3) As to the extent of disease determined by the barium enema & endoscopy, rectum or rectosigmoid colon was involved in majority of the cases 22.6%, 41.9 (respectively). 4) Significant laboratory findings were elevated ESR, anemia, leukocytosis, hypoalbuminemia. 5) The endoscopic examination was performed in all 31 cases and showed sinificant findings such as hyperemia, mucosai edema, superficial ulceration & mucosal friability. 6) 23 of 26 cases treated by sulfasalazine medication showed improved, and 3 cases were improved by steriod medication and the surgical operation was indicated in 1 case.

PURPOSE: The purpose of this study was to analyze the clinical features and to assess the risk factors in the treatment of small-bowel obstructions. METHODS: This retrospective clinical report was based on the medical records of 67 patients who were treated between Jan. 1992 and Dec. 1999 and who had had a history of abdominal surgery due to cancer. RESULTS: The distribution of primary cancer was as follows: stomach cancer 36 (53.7%), colorectal cancer 25 (37.3%), uterine and ovarian cancer 4 (6.0%), and other cancers 2 (3.0%). The mean interval from the primary operation to the development of a small- bowel obstruction was 27 months. Conservative treatment produced a successful outcome in 36 patients (59.0%), but recurrences of obstruction were noted in 18 of those patients. There were 34 operations in 30 patients. The initial success rate of operative treatment was 80% (24/30), obstructions recurred in 6 patients. The causes of obstructions in the surgically treated patients were adhesion (53.3%) and recurrence of cancer (46.7%). The postoperative complication rate was 44.1%, and the mortality rate was 20.0%. The mean survival time of the patients with benign causes of obstruction was significantly longer than that of the patients with malignant causes of obstruction (46 months vs 11 months). CONCLUSION: In the treatment of such patients, conservative treatment should be considered first. However if conservative treatment fails, surgery should be done without hesitation, especially in patients with no definite evidence of recurrence.

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.

An unusual case of glroependymal cyst involving the lateral ventricle, 3rd ventricle, cerebellopontine angle cistern and prepontine cistern, simultaneously, is reported. The glroependymal cyst is benign developmental cyst that mainly occurs in the cerebrospinal axis in relation to ventricle, but occasionally occurs in relation to extraventricular system, such as subarachnoid space, brain stem and cerebral parenchyme. The histological characteristics of ependymal cyst wall are ependyma-like epithelium and neuroglial tissue.

Serum HBsAg, AntiHBs, HBeAg, AntiHBe, and AntiHBc were detected by radioimmunoassay in 39 patients with acute viral hepatitis, 79 patients with chronic hepatitis, 30 patients with liver cirrhosis, 16 patients with primary hepatocellular carcinoma, 14 patients of HBsAg carriers and 129 cases of controls: 78 cases of normal level of SGOT, SGPT, and 51 cases of elevated level of SGOT, SGPT. Following results were obtained: 1. HBsAg was detected in 66.7% of acute viral hepatitis, 63.3% of chronic hepatitis, 36.7% of liver cirrhosis, 81.3% of primary hepatocellular carcinoma and 27.1% of controls. 2. AntiHBs was positive in 0% of acute viral hepatitis, 21.5% of chronic hepatitis, 36.7% of liver cirrhosis, 31.3% of primary hepatocellular carcinoma, 0% of carrier and 44.2% of controls. 3. HBeAg was detected in 45.6% of chronic hepatitis, 23.3% of liver cirrhosis and 31.3% of primary hepatocellular carcinoma. 4. Among chronic liver diseases, antiHBe was positive in 56.3% of primary hepatocellular carcinoma, 23.3% of liver cirrhosis and 20.3% of chronic hepatitis. 5. AntiHBc was detected in most of all examinees and the significance of presence of AntiHBc does not seem to represent liver disease itself but the evidence of infection of HBV. 6. Among 14 HBV carriers, 6 cases presented with abnormal SGOT, SGPT. 7. All HBV markers were negative in 5.1% of acute viral hepatitis, 5.1% of chronic hepatitis and 14.7% of controls: 17.6% of subjects with abnormal SGOT, SGPT and 12.8% of subjects with normal SGOT, SGPT. 8. Beside of HBV, other causes, such as non A, non B virus, Delta-agent, other viruses or related factors should be excluded among the patients with evidence of HBV infection associated with elevation of SGOT & SGPT.
