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.

A case of hypertrophic interstitial neuropathy in a 32 years old man developed in the median nerve is reported. This is a rare disease characterized by thickened peripheral nerves which may be palpable and visible. This case was treated by excision of transverse carpal ligament and external and internal neurolysis.

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.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

The measurement of gastric emptying time is useful in differentiation of the hypochondriacal neurosis from the functional gastrointestinal disturbance, and also useful in searching the hidden gastro-intestinal disease in patients who are believed as the functional gastrointestinal disturbance. We confirmed in this study that the more delayed gastric emptying time was measured in functional gastrointestinal disturbance compared to normal group, and more shortened gastric emptying time was found after treatment with dopamine antagonist (cleboril) in this group.

The purpose of this study was to evaluate the effect of modified calcium sulfate paste on periodontal regeneration. 1-wall intrabony defect(mesio-distal width: 4mm, depth: 4mm) was surgically created on the distal side of P2 and mesial side of P4 in four dogs. The control group(GFS) was treated with conventional flap operation alone, and the experimental group(CS) observations were as follows. 1. The length of the junctional epithelium was 0.41+/-0.0lmm in the control groups, 0.47+/-0.0lmm in the experimental group. 2. The connective tissue attachment was 0.28+/-0.02mm(6.15+/-0.28%) in the control group, 0.18+/-0.0lmm(3.41+/-0.14%) in the experimental group. The control group showed more connective tissue attachment. 3. The new cementum formation was 3.80+/-0.06mm(84.80+/-0.33%) in the control group, 4.49+/-0.06mm(87.57+/-0.15%) in the experimental group. Both groups showed a lot of new cementum formation. 4. The new bone formation was 1.43+/-0.03mm(32.37%) in the control group, 2.04+/-0.09%nm(40.94%) in the experiment group. 5. The inflamatory cells were observed partially around resorbed calcium sulfate in the connective tissue of the experimental group. 6. Partially resorbed calcium sulfate were found within the connective tissue, around alveolar bone, and in the newly formed alveolar bone, On the basis of these results, newly formed calcium sulfate paste enhanced new bone formation and new cementum formation. The resorption rate of calcium sulfate seems to he controlled by the add-in compounds. Thus research about biocompatibility and adequate resorptionrate is required to develop a improved material.

Gottron's acrogeria syndrome is a rare genetic disease of unknown etiology with some features suggestive of accelerated aging. The typical clinical presentation consists of premature aging of the skin with atrophy of the cutis and the subcutis. After a brief review of the literature available on this syndrome, we report a case of Gottron s acrogeria syndrome in a 19 year-old man whose right rectus femoris muscle had a fibrotic contracture.
