We built the hypothesis that the hypertrophic callus formation is mediated by beta-endorphin that stimulates secretion of GH and increase circulation growth factor activity in head injury patient. We classified 4 groups such as 5 normal person(control), group I;5 patients with only fracture, group II;5 patients with fracture and head injury, group III; 5 patients with only head injury, group IV. We obtained the samples of serum from each group at 0, 2, 4, 6, 8 weeks after trauma and assessed the serum level of GH, GHRH, somatostatin. The serum level of GH was statisticallyu higher in group III, IV than group I, II. There was not significant difference in serum level of GHRH. The serum level of somatostatin was higher in group II, III, IV than group I, but there was no statistical significance in each group. GH has a important role in hypertrophic callus formation in severe head injury patients, but there was no evidence that the mechanism is mediated by beta-EndorphinGHRH & somatostatin-GH-GF-1, beta-FGF axis. There may be a another mechanism in increasing GH that was stimulated by beta-endorphin in thalamus and lateral ventricle, and it should be necessary for further evaluation of it.

Upper gastrointestinal(UGI) bleeding was critical disease that was commonly found in emergency department and needed more early diagnosis and rapid treatment for decreasing mortality and morbidity. It's causes and frequencies here affected by many factors, but the majorities were caused by peptic ulcers and esophageal-gastric varices. With development of economy and medical services, new drugs and endoscopic interventions, the treatment of patients with UGI bleeding was more improved. So I would like to evaluate the change of causes and frequencies of UGI bleeding and the associated clinical findings. A total of 1,546 patients presented with UGI bleeding in emergency department of Yeungnam university hospital during the five years from Jan. 1991 to Dec. 1995 were clinically reviewed by charts and compared with previous seven years report from Jan. 1984 to Dec. 1990 in the same hospital. The ratio of male to female was 6.1:1 and slightly increased in comparison with previous seven years. The incidences in 6th and 5th decades were highest(54.4%) as like as previous seven years. Age distribution of duodenal ulcer bleeding, Mallory-Weiss tear and acute gastric mucosal lesion were developed in lower decades than the others. The causes of UGI bleeding were caused by esophageal varix(45.4%), peptic ulcer(38.8%), Mallory-Weiss tear(4.3%), gastric cancer(3.8%), others(3.1%), acute gastric mucosal lesion(2.7%), undetermined causes(1.8%) in defending order of frequencies. The proportion of esophageal varices was increased from 36.6% to 45.4%, but that of peptic ulcer was relatively decreased from 47.6% to 38.8%. And the annual distribution of varices was increased, however the annual distribution of peptic ulcers was increased. Although the ranking of annual distribution of gastric ulcers and duodenal ulcers were not changed compared to previous study and the frequency of gastric ulcers was increased since 1992, but additional follow-up was needed. Seasonal variations were found that upper gastrointestinal bleeding was increased in fall and peptic ulcer bleeding was increased significantly in summer and fall, however, varix bleeding was less frequent in summer time as like as previous seven years. Emergency endoscopic examination was performed within 6 hours far 54.5%, 24 hours for 90.8% and this reacts were to be like previous results, 57.5% and 90.7% respectively. Findings of emergency endoscopic examination were active bleeding focus(21.2%), blood clot(7.9%), exposed vessels(13.3%), flat blood spot(6.4%) and lesion without evidence of bleeding(51.3%). Endoscopic findings of active bleeding were easily seton when examination was perfomed within 24 hours. Blood transfusion was performed in 67.3% with average 2.1 units. When the causes of bleeding were due to varix and marginal ulcer, more amounts of blood were transfused than the others. In previous seven years, blood transfusions were performed in 71.2% with average 5 units and more amounts of blood were transfused in gastric cancer and varix bleeding.

The clinical triad of relapsing iritis, ulcers of the mouth and genitalia was first described in 1939 by Hulusi Behcet. This entity, originally confined to the above triad of symptoms appears to be systemic disease manifested by skin lesion, thrombophlebitis, neurologic, cardiovascular or visceral symptoms. The vascular involvement in Behcet's syndrome has been reported since Mischima first described a case in 1961, four types of vascular lesion are freuqnetly observed most commonly on the inferior or superior vena cava. Treatments consist of anticoagulation and administering oral steroids. We report a case of SVC obstruction in 36 years old female patient with Behcet's syndrome.

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.

5 cases of lead poisoning were investigated clinically. Of the 5 patients, 4 were male and 1 was female. The causes of lead poisoning in 3 cases were ingestion of herb drug pills and in 2 cases were occupational poisoning. Chief complain at admission in 4 cases were ill defined colicky abdominal pain and constipation. Only 1 case complained of dizziness and palpitation without gastrointestinal symptom. On peripheral blood, normocytic normochromic anemia (mean Hgb 9.2 gm/dl), reticulocytosis (mean 4.7%) and basophilic stippling were found in 100% of patients. Bone marrow aspiration was done in 4 cases. Erythroid hyperplasia and basophilic stippling were found in all 4 cases. Mean M:E ratio was 0.7:1. The lead concentration in serum was increased in 4 cases (80%) of patients. Lead concentration, delta aminolevulinic acid concentration in 24 hours collected urine were increased in 5 patients (100%).

We calculated the age specific Proportionate Morbidity Ratio(PMR)' for different areas as the outcome index by using the national cancer registry data(1988 1991) to assess the patterns of stomach cancer and bladder cancer. Also, we calculated 'Manufacturing workers Concentration Index(MCI)' for different areas as the exposure index by using the census data reported in 1980 to assess the relationship between cancer site specific PMRs and MCIs. As a result, we found the significant correlation(r=0.61, p=0.002) between the bladder cancer in the age of 40s and the industrial exposure indicator. Future analytic studies should be fruitful in identifying more occupational risk factors for bladder cancer. Investigation of cancer incidence including geographic variations and difference by age may identify patterns suggesting occupational exposures.
