This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Etretinate is a synthetic retinoic acid which has been reported effective in hyperkeratotic disorders. Recently, it has also been tried, on a limited number, for the treatment of viral wart. A 33-year-old male patient presented with multiple, tender, confluent, verrucous lesions on the scalp, both hands and feet of 4 years duration. Before coming to us, he had been treated with intralesional injection of bleomycin and electrodesiccation with little effect. We started etretinate therapy in a daily dose of 70mg(1mg /kg). After 3 weeks treatment, most of his skin lesions were flattened and softened: but an abrupt elevation of serum aminotransferases was noticed, which was normalized soon after cessation of medication. Unfortunately, the drug stop page aggravated most of skin lesions. After two weeks of withdrawal we started again the drug in a daily dose of 30mg and observed a good response without hepatic dysfunction.

In the past two decades, the incidence of rubella infection has decreased due to a nation-wide rubella vaccination program. Therefore the rate of rubella Ig G antibody has decreased. This means an increasing vulnerability to rubella infection among the group, with negative Ig G antibodies. The study was conducted in January of 1992 to April of 1996. The subjects were 1,010 fertile women(ages 20/45 years). The study was performed at Park Women`s Clinic to investigate the status of rubella antibody in Korean fertile women. The results were as follows. 1. The positive rate of rubella Ig G and Ig M antibody were 80.5% and 1.5%, respectively. 2. The mean age of positive rubella Ig G group was 28.5+/-3.6 years. The positive rate of rubella Ig G antibody was decreased by an increase in age with a significant level at p < 0.05. 3. The positive rate of rubella Ig G antibody was 63.3% in 1992, 71.3% in 1993, 87.5% in 1994, 81.1% in 1995 and 83.8% in 1996. The increase in the positive rate of rubella Ig G antibody by year for 5 years was statistically significant at p < 0.05. 4. The positive rubella Ig M antibody was noted in 15 women. Among them, one woman was tested in 1993, 5 women in 1995 and 9 women in 1996. The incidence of rubella infection had increased by years, and was statistically significant at p < 0.05. 5. The mean titer of rubella Ig G antibody was 47.18+/-50.04 IU/ml. The titer of rubella Ig G antibody was decreased by the increased in at age(p < 0.05). We observed a low positive rate of rubella Ig G antibody as compaired with other studies that were performed before 1990. Therefore, to prevent sporadic rubella infections, rubella vaccinations should be given to unmarried women.

This study was conducted to investigate the vibrio flora in edible shellfish (Ruditapes philippinarum, Scapharca broughtonii, Batillus cornutus and Mytilus coruscus) which were purchased from seafood-market or collected from shellfish culture bed in Pusan and Masan Bay from May to October 1997. Sixty-three vibrio strains were identified among 438 collected strains. Five species of vibrios [V. alginolyticus (22 strains), V. parahaemolyticus (35 strains), V. costicola (2 strains), L. damsela (V. damsela 2 strains), and V. cholerae non-Ol (2 strains)] were identified by their phenotyfic and biochemical characteristics. Four groups (142 strains) were identified as genus Vibrio by their biological characteristics, but they could not be identified to the species level.

PURPOSE: To illustrate frequently encountered anatomic variations on PNS computed tomography(CT) and to assess their clinical significance. MATERIALS AND METHODS: CT findings of 1523 patients, who underwent PNS CT with no history of sinus surgery, were reviewed, and prevalence of each anatomic variation and its relationship with mucociliary clearance pathway was evaluated. RESULTS: Two categories of anatomic variations were encountered. The first group included variations of the turbinates, such as concha bullosa(28.6% ), paradoxical middle turbinate(31.5%), of the uncinate process, such as medially bent or folded(36.3%), laterally bent(3.7%) or uncinate bulla(0.5%), of the ethmoidal sinus, such as Haller's ce11(28.2%), large agger nasi ce11(9.6%) or large ethmoidal bulla(23.5%) and nasal septal deviation(24. 1%), which might cause obstruction of mucociliary clearance pathway and thus give rise to secondary obstructive sinusitis. The second group included Onodi ce11(1.4%) and medial depression of the lamina papyracea (3.5%), which were not related with obstructive sinusitis. 87 cases of large agger nasi cell were associated with obstruction of nasofrontal recess. Large ethmoidal bulla(452 cases), Haller's ce11(245 cases) and true concha bullosa (25 cases) contributed to narrowing of the infundibulum. Medially bent uncinate process(220 cases), concha bullosa(157 cases), paradoxical middle turbinate(126 cases) and nasal septal deviation(93 cases) were observed in middle meatal obstruction and supreme concha (3 cases) accompanied sphenoethmoidal recess obstruction. CONCLUSION: Recognition of anatomic variations on PNS CT is important to build a treatment plan in patients with obstructive sinusitis as they may represent causes of the disease, and to avoid critical complications during functional endoscopic sinus surgery.

BACKGROUND: Antistreptolysin O (ASO) has been widely used to diagnose Streptococcus Pyogenes infections and their sequelae, rheumatic fever and acute glomerulonephritis. Butt in some cases there is no elevation of ASO that it is necessary to add one or more tests detecting immune response to S. pyogenes.. The authors analyzed the distribution of antideoxyibonuclease (ADNase) B and antistreptolysin O (ASO) among the children of an elementary school in Seoul and calculated their upper limit of normal (ULN) value. METHODS: ADNase B concentrations were determined by nephelometry (Behring Nephelometer 100 Analyzer, Germany) on 236 sera of healthy elementary school children in Seoul. Throat cultures were taken at the same time to compare ADNase B lovels between S. pyogenes carriers and non-carriers. RESULTS: The distribution of ADNase B concentrations among school children ranged from 77 (detection limit) to 1616 IU/ml and the ULN was estimated to be 362 IU/mL. The carriers of S. pyogenes clad significantly higher ADNase B levels (mean 392 IU/ml) than carriers of non-group A beta-hemolytic streptococci (BHS, 236 IU/ml) oY non-carriers of BHS (234 IU/ml). The relationship between ADNase B (Y) and ASO (X) levels was Y=0.4X+173 (r2=0.209). CONCLUSIONS: The distribution of ADNase B levels showed no close correlation with that of ASO, and ADNase B test was considered to have additive value to ASO test for detecting S. pyogenes infection.
