This study was conducted to evaluate the effects of lead on the incidence of anemia and to find cases with lead poisoning early among female workers who have been exposed to lead occupationally, for one year from August, 1985. The level of blood lead and hemoglobin concentration were observed for 284 female lead workers and 123 female non-lead workers of industries in the Gumi industrial complex in Kyungpook Province. The average age was 20.3±2.9 years and 21.1±3.5 years in lead workers and non-lead workers, respectively. The average working duration was 26.46±19.26 months in lead workers. The mean value of blood lead was 30.11±6.61 µg/100 ml and 21.86±3.75 µg/100 ml in lead workers and non-lead workers, respectively. There were significant differences between two groups. The mean value of hemoglobin concentration was 14.00±0.57 g/100 ml and 14.03±0.64 g/100 ml in lead workers and non-lead workers, respectively. Anemia cases were not observed at Hb concentration below 12g/100 ml. The percentages of lead workers at Hb concentration ranged 12.0~13.0 g/100 ml were 4.5%. There was no dose-response relationship between blood lead level and the incidence of anemia. There were no remarkable differences between age and blood lead level as well as Hb concentration, and between working duration and the level of blood lead and hemoglobin.

5.Neuropsychological Assessments in the Elderly with Questionable Dementia of the Alzheimer Type.
Journal of Korean Neuropsychiatric Association 1997;36(4):705-711
OBJECTIVE: Elucidation of questionable dementia of the Alzheimer type(QDAT) is important far accurate estimation of prevalence and incidence of dementia of the Alzheimer type, understanding of its natural history and evaluation of treatment strategies for dementia of the Alzheimer type. Subject and METHODS: Performances neuropsychological tests were compared between non-demented controls and 14 elderly people in a community diagnosed as having questionable senile dementia of the Alzheimer type. They lived in a rural community and their sex, age and education were controlled. RESULTS: The two groups were not significantly different comprehension and digit span of the Wechsler Memory Scale. Performances on arithmetic, similarity and block design were significantly lower in QDAT subjects. Scores on associate learning of the Wechsler Memory Stale and immediate and delayed recalls of logical memory were lower in QDAT subjects with statistical significance. performance on the semantic verbal fluency tended to the lower for the QDAT subjects. CONCLUSION: These findings suggest that QDAT may be early dementia of the Alzheimer type.

The authors studied depression in 5,869 college students (male: 3,893, female: 1,976) using Zung's Self-Rating Depression Scale (SDS). The results are as follows: 1) Female college students showed significantly higher total depression scores than male college students (p<0.001). 2) The items of confusion, indecisiveness, and psychomotor retardation were scored higher in both groups and the items of suicidal rumination, psychomotor agitation, constipation and tachycardia were scored lower in both groups. 3) 18.2% of male college students showed rather serious depression level of score 50 or higher, while 33.1% of female college students showed the same scores. 4) The psychosocial factors relating to pessimistic views to past, present & future self-images showed significantly high depression scores. 5) The depression items of fatigue, anxiousness, tachycardia, apprehension, fear, and body aches & pain were correlated significantly over 0.40 of correlation coefficient.

The authors studied anxiety, using Zung's SelfRating Anxiety Scale (SAS), in the subjects of 3,893 male and 1,976 female college students of Yeungnam University. The authors collected the reports of SAS during the periods from October to November, 1984, and applied ANOVA and ttest on the anxiety scores in order to compare them between various psychosocial factors, and sexes. The results could be summarized as follows: There was significant difference in the mean averages of total anxiety scores between male and female students; male students scored 36.92±7.07, female students scored 39.63±7.51, p<0.001. The anxiety scores relating to the items of sweating, apprehension, restlessness, insomnia, dyspnea were relatively higher in both groups. The anxiety scores in the items of paresthesias, mental disintegration, tremors, faintness, dizziness were lower in both groups. Two hundred and one male students (5.2%) showed seriously high anxiety scores of 50 or higher, while 201 female students (10.2%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but females showed more various symptoms and higher level of anxiety than males. In a comparison between male students in different school grades, freshmen showed the highest level of anxiety scores and as the grades of the students became higher, the levels of anxiety scores were lower. The female students who resided in dormitory or other residences, and whose educational fees were paid by brothers or sisters, showed higher level of anxiety scores. There was s strong tendency toward higher anxiety scores in the students who were dissatisfied with their colleges or departments, and who had pessimistic views of self-image in the past, present, or future, in both groups.

Aim. A neurobehavioral test for workers exposed to organic solvents in the workplace can be affected by many factors : age, education, motivation, ethnicity, etc. To apply more suitable neurobehavioral test for Korean workers, we evaluated the validity of several items of computerized and traditional neurobehavioral tests. Methods. We have applied eleven tests : four items of computerized neurobehavioral test(Swedish Performance Evaluation System) including Addition, Symbol-Digit, Digit Span, and Finger tapping speed, and seven items of traditional neurobehavioral test consisting of Addition, Digit-Symbol , Digit Span, Benton visual retention test, Pursuit aiming, Pegboard, and Tapping. These tests were performed on 96 workers exposed to solvents, and 100 reference workers. The concurrent and construct validities were evaluated by group difference, correlation with age, educational level, hippuric acid level, neurotoxic symptom, current exposure level, multitrait-multimethod matrix, factor analysis, and discriminant analysis. Results. Statistically significant differences were observed between the workers exposed to solvents and referents in computerized Symbol-Digit, Finger tapping speed, traditional Digit-Symbol and Pegboard. The computerized Symbol-Digit, traditional Digit-Symbol, Addition, Benton visual retention test, and Pegboard were found to be related to the age. The performance of computerized Symbol-Digit, Addition, and traditional Digit-Symbol were found to be related to the educational level significantly. The computerized Symbol-Digit, Finger tapping speed, and traditional Digit-Symbol were found to be related to hippuric acid, and neurotoxic symptom. The discriminability of Finger tapping speed, and Pegboard was better than the other tests. In discriminant analysis, the model with two variables, the computerized Symbol-Digit and Pegboard, classified almost 70 percent of the workers correctly. Conclusions. These results suggest that the computerized Symbol-Digit, Finger tapping speed, and Pegboard are more satisfactory for our purpose, and the Addition, Tapping, Benton visual retention test, and Pursuit aiming are less valid than other items. These may allow the reasonable selection of core neurobehavioral tests for workers exposed to solvents in Korea.
