To assess the pattern of psychiatric symptoms and to evaluate the relationship between exposure related variables(duration of work and urinary hippuric acid concenturation) and psychiatric symptoms in organic solvent exposed workers, case control study of forty-two solvent exposed workers and ninety-six non-exposed workers was conducted. The general health questionnaire 28(GHQ28) was administered to evaluate psychiatric symptoms and urinary hippuric acid concenturations was measured to estimate the present status of solvent exposure in exposed group and to estimate normal level in non-exposed group. The meand concenturation of urinary hippuric acid was significantly higher in exposed group (2.953g/creatinine g) than non-exposed group (0.395g/creatinine g) (P<0.01). The total positive rates of symptoms were significantly higher in exposed group(28.2%) than non-exposed group(17.5%) (P<0.05). The positive rates of symptoms for four sub-scales of GHQ 28 in exposed group were in the order of somatic symptoms, anxiety, social dysfunction, depression and in the order of social dysfunction, anxiety, depression, somatic symptoms in non-exposed group.The positive rates of symptoms for somatic symptoms and anxiety were significantly higher in exposed group than non-exposed group (P<0.05) and the proportion of workers with six or more positive symptoms(dysthymic states) in exposed group were significantly higher than non-exposed group (P<0.01). After the effect of age, sex, level of income, level of education, and duration of work were controlled, the total score of GHQ28 was still significantly different between exposed and non-exposed group(P<0.01). In multiple logistic regression analysis on the dysthymic state, the odds ratio of level of income was statistically significant in both group. The odds ratios of exposure related variables such as duration of work and hippuric acid concenturations were not statistically significant but there was a tendency that exposure related variables had an effect on dysthymic state in exposed group.In future, comtinuous evaluation of psychiatric symptoms on organic solvent exposed workers and studies to detect the factors that affect on psychiatric symptoms are required.

The effects of treatment with mercury chloride on the nitrite and nitrate syntheses were observed in peritoneal macrophages from Balb/c mice and EMT-6 cells in vitro. The cells were cultured in Dulbecco's modified Eagle's medium(DMEM) with cytokines. Amounts of nitrite and nitrate in the culture media after 24 and 36 hours of culture were about 2-fold, and 3-fold of those measured after 12 hours respectively. There were very close associations between the amounts of nitrite and nitrate measured in the culture media according to culture time. The survival rate of peritoneal macrophages was significantly decreased by mercury chloride added into the media in dose-dependent manner, however the survivals of EMT-6 cells were not influenced by mercury chloride concentration in media. Nitrite and nitrate syntheses were dose-dependently decreased by mercury chloride added in culture media. ATP synthesis also decreased in EMT-6 cells by mercury chloride. These results reported here suggest that the disorder of cell mediated immunity by mercurials could be related to the inhibition of nitric oxide synthesis which seems to be caused by the inhibition of ATP synthesis.

Mail questionnaire was administrated to 370 practising physicians and 388 pharmacists in Taegu city selected by systematic sampling to examine utilization states and opinion of pharmacy under medical care insurance programme and the attitude to the functional division between physicians and pharmacists from April to May 1992. Regarding the opinion on the outcome of drug-store under medical insurance, 71.2 percent of practicing physician answered failure but 13.4 percent of practicing pharmacists answered failure in contrast. Fifty percent of practicing physician asserted introducing functional division between physician and pharmacist while 66.9 percent of practicing pharmacist answered drug-store under medical insurance itself is successful programme. Average daily numbers of preparation of medicine was 32.2 case. Percentage of utilization of drug-store under medical insurance to average daily cases of preparing of medicine was 20 percent, percentage of utilization with physician's prescription was 0.7 percent. And 58.7 percent of practicing physician experienced outside the institute prescription. Regarding the opinion on the pros and cons of enforcing functional division between physician and pharmacist, 59.2 percent of practicing physician preferred pros and 17.7 percent cons ,but 38 percent of practicing pharmacist preferred pros and 45.5 percent cons. And pharmacist know better the content of functional division between physician and pharmacist, practicing emphasized to prevent misuse or abuse of medicine but practicing pharmacist emphasized to display physician and pharmacist's professional ability. And as an opinion on implementation style of functional division between physician and pharmacist in pros respondents, practicing physician favored mandatory enforcement (52.3%), while practicing pharmacist favored partial incomplete functional division (81.7%). As the method of prescription if functional division between physician and pharmacist will be enforced, both practicing physician and pharmacist preferred generic name (44.0%, 89%) mostly, but physician preferred brand name (35.3%) secondly. Regarding the reason for not implementing functional division between physician and pharmacist up to date, both physician and pharmacist answered problem of business right between physician and pharmacist, followed by lack of recognition, and interest of people and lack of the governmental willness. Regarding the opinion on prior decision of condition for enforcing functional division between physician and pharmacist, practicing physician and pharmacist named uneven distribution of medical facilities and drug-store between rural and urban, inequality of physician and pharmacist manpower and the problem of manpower demand and supply mostly, and practicing physician pointed out establishing attitude of acceptance on the part of pharmacist and practicing pharmacist favored establishing attitude of acceptance on the part of physician, which was different attitudes between physician and pharmacist. Following conclusion was reached; 1. Current drug-store under medical insurance program yield insufficient outcome, so we should consider program conversion from drug-store under medical insurance program to functional division between physician and pharmacist. 2. There were problem of business right and conflicts between physician and pharmacist at enforcing functional division between physician and pharmacist, so the government should search for formulating plan to resolve the problem and have neutral willness for the protection of the national health.

The spinal injuries were classified into bursting fracture, fracture-dislocation, seat-belt injury, compression fracture according to the three column theory by Denis. The bursting fracture and fracture-dislocation required the most careful planning. So, myelography, computerized tomography enabled us to diagnose the spinal fracture including retropulsed bony fragment into the spinal canal. There was much controversy as to appropriate treatment af unstable thoraco-lumbar fractures. The frequent surgical treatment of thoraco-lumbar spinal fractures was still posterior spinal instrumentation including Harrington rod system. Since 1964, the use of anterior spinal instrumentation had been started by Dwyer, Dunn, Kostrik, Slot, and Zielke used anterior spinal instrumentation in unstable thoraco-lumbar spinal fractures, but not popular. This study suggested the experience to accomplish the decompression of the neural elements and stabilization of the spine by using Kandea device in unstable thoraco-lumbar spinal fractures. 12 patients treated with this Kaneda device in unstable thoraco-lumbar spinal fractures were analyzed from Dec. 1988 to May, 1989 at the Department of Orthopaedic Surgery, Ewha Womans University Hospital. We obtained the following conclusions. The results were as follows. 1. The common injury mechanism was falling down in 5 cases, the frequent injury site was 1st lumbar vertebra. 2. According to Denis classification, the bursting fractures were in 8 cases(68% ), the fracture-dislocations were in 4 cases(33%). 3. The average preoperative kyphotic angulation was 24.5 degrees(range 8 to 45) and postoperative angulation was 5 degrees(range 2 to 15), the correction rate was 79.6% and correction degree was average 19.5 degrees. 4. The advantages were the fixation of one level above and below the injury site, sufficient neural decompression, firm spinal stabilization, early mobilization with a brace and elimination of the 2nd posterior procedure. 5. The fixation of vertebral plate was difficult due to the invariable size of vertebral plates, especially, in upper thoracic spinal fracture and children's fracture.

This study was done to identify the association between serum copper and zinc levels and the cirrhosis and hepatocellular carcinoma(HCC), and to evaluate its diagnostic value on liver diseases. Sixty-three healthy persons, 60 patients with cirrhosis and 33 patients with hepatocellular carcinoma were rendomly selected and investigated for their general characteristics from October 1990 to August 1991. For analysis of the biochemical markers in liver function test and the serum copper and zinc levels, their fasting venous blood were sampled at 9:00 to 11:00 in the morning and centrifuged to separate the serum within one hour. All the samples were immediately analysed for biochemical markers and stored at -20 C in polypropylene tubes further copper and zinc analysis. Mean of serum copper levels was 91.97+/-4.76 microgram/dl in control, 106.21+/-2.73 microgram/dl in cirrhosis and 127.05+/-0.77 microgram/dl in HCC. The value of HCC was statistically significantly higher than that of the control and cirrhosis(p<0.05). Serum zinc levels were 110.82+/-7.24 microgram/dl in control, 68.10+/-5.43 microgram/dl in cirrhosis and 63.78+/-2.20 microgram/dl in HCC. The values of cirrhosis and HCC were statistically significantly different among three groups(p<0.05). Test total protein, albumin, ALP and total bilirubin of biochemical markers of liver function were statistically significantly different among three groups(p<0.05). Differences between cirrhosis and HCC for ALT and AST, and between the control and HCC for direct bilirubin were not statistically significant. Biochemical markers statistically significantly correlated with serum copper and zinc levels and Cu/Zn ratio(p<0.05), were variable in three groups. In multiple logistic regression, odds ratio of serum copper level and Cu/Zn ratio had no statistically significance on the cirrhosis and the HCC, but that of serum zinc was statistically significant as 0.951 and 0.952 (p<0.05). Serum copper and zinc levels and Cu/Zn ratio were not statistically significantly different between the cirrhosis and HCC. Albumin, ALP, zinc, total bilirubin and age among all variables were selected as main variables for three-group discriminant analysis. Percentage of "grouped" cases correctly classified by these five variables was 98.4 for control, 73.4 for cirrhosis, 75.7 for HCC and 84.0 for all subjects. This study suggests that zinc may has an independently inhibitory effect on the liver disease and serum zinc level is considered to play a role as diagnostic marker on the hepatic disorders and be more useful than serum copper level and Cu/Zn ratio in diagnosis of the liver diseases.

Papillary eccrine adenoma, first described by Rulon and Helwig in 1977, is a rare benign adnexal neoplastn. It is usually present as a solitary dermal nodule on the distal extremities. It has characteristic histopathological findings, consisting of dilated ducts that contain eosinophilic secretions and are associated with intralummal papillations. On the basis of histological and histochemical studies it is believed to be an adnexal neoplasm of possible eccrine differentiation. We report two recent cases of papillary eccrine adenomas occuring in two young male patients without subjective symptoms who had firm dermal nodules on the extremities.

BACKGROUND: Self-expandable metallic stent is an effective method in palliative treatment of malignant biliary stricture. However, it is controvesial in benign biliary stricture due to recurrent jaundice, cholangtitis, and finally, obstruction of stent. The purpose of this study was to determine the long-term effectiveness of Gianturco expandable metallic stents in benign biliary strictures. METHODS: We inserted Gianturco self-expandable metallic stent in 13 patients (42~69 years old, 6 men and 7 women) with benign biliary stricture between November 1991 and September 1994 in Wonkwang University Hospital. All patients had a previous history of biliary surgery and underwent balloon dilatation procedure for management of strictures. Insertion routes were percutaneous transhepatic biliary drainage tracks in 8 cases and T-tube tracks in 5 cases. The insertion site was the right intrahepatic duct in 5 cases, the left intrahepatic duct in 2 cases, both intrahepatic ducts in 1 case, common hepatic duct in 1 case, and distal common bile ducts in 4 cases. The stents used were 2~6cm in length and 8~12mm in diameter. The follow-up period was 46months to 81months(mean, 67months). RESULTS: The initial technical success rate was 100% with good immediate patency in all patients. Nine patients(69.2%) had no recurrence of the initial strictures during the follow-up period and 4 patients(30.7%) had further symptoms of biliary obstruction caused by recurrent cholangitis or intrahepatic duct stone formation. These 4 recurrent biliary strictures were treated by surgical methods. The recurrent stricture sites were distal common bile duct(1case), left intrahepatic duct(1case), both intrahepatic ducts(1case), and Roux-en-Y hepaticojejunostomy site(1case). CONCLUSIONS: According to the results of long-term follow-up, expandable metallic stent is a useful method in recurrent biliary strictures, especially in the case where operation is not feasible; poor risk patients, patients refusing operation, multiple biliary operation.
