By using Factor analysis on the variables relating to the subjective symptoms of total 56 workers, who have exposed to mixture of organic solvents at the musical instrument manufacturing plant, as experimental group, and 70 workers, who worked in noisy working environment as control group, the study was performed. It was confirmed that the variables found in hematological figures, age specification, occupational history and physical examination have a influential factor on the subjective symptoms of both groups. It was explicated that the ratio of these to total Eigen Values showed 31.1 percent in experimental group and the control group revealed 37.7 percent.

Forced vital capacities (FVC's) and forced expiratory volumes in one second (FEV1.0's) of 26 pneumoconiosis patients were checked at admission and were followed up for 10 months through hospitalization. FVC's and FEV1.0's were slightly improved in 10 months after admission. The improvement of FVC's was statistically significant. In the group of large opacities in chest radiographs, FVC's and FEV1.0's were lower than those values in small opacity group at admission but improved more progressively. Similar finding was noted in the group of emphysema; those values were lower at admission but improved more progressively than those of non-emphysema group.

Chronic alcohol use may have direct or indirect neurotoxic effects on the brain that can lead to cognitive impairment. However, the precise relationship between alcohol and dementia remains unclear. There are several epidemiological studies suggest that the protective effect of light-moderate alcohol drinking in dementia. But obviously the heavy alcohol drinking can lead to brain damage and increase the risk of various types of dementia. The clinicopathological issues and criteria regarding so-called 'alcoholic dementia' remain under debate. Alcohol-induced persisting amnestic disorder, alcohol-induced persisting dementia, and Wernicke-Korsakoff syndrome (thiamine deficiency) may constitute distinct disease entities, but they may also share some common features. Based on this theory, Oslin and colleagues proposed the broader diagnostic scheme and criteria for Alcohol Related Dementia (ARD), which may include cases of Wernicke-Korsakoff syndrome and also other cases of dementia that appear to be alcohol-related. In pathogenesis of the alcoholic dementia, the chronic exposure to ethanol results in the adaptive up-regulation of NMDA receptor sensitivity, which can result in an increased vulnerability to glutamate induced excitotoxicity. Despite the clinical importance of ARD, few medical treatments for ARD have been proposed and studied. Most of all, the gold standard of the treatment in alcoholic dementia is the maintaining abstinence. Some therapeutic trials with cholinesterase inhibitors (donepezil and rivastigmine) and memantine (NMDA receptor antagonist) have been conducted for the patients with Wernicke-Korsakoff syndrome and alcohol-related dementia, and these studies reported favorable outcomes. Especially memantine can be a more effective agent in the treatment of alcoholic dementia because of anti-craving effect reported in several studies.

OBJECTIVES: This study was designed to investigate the association between Ser311/Cys311 polymorphism in the dopamine D2 receptor gene and bipolar disorder in korean population. METHOD: Ser311/Cys311 polymorphism in the dopamine D2 receptor gene was typed with PCR in 86 bipolar disorders and 100 normal controls. RESULTS: Genotype of Ser/Ser, Ser/Cys, Cys/Cys were 82 (95.3%), 4 (4.7%), 0 (0.0%) respectively in the bipolar disorders, 96 (96.0%), 4 (4.0%), 0 (0.0%) respectively in the controls. Allele frequencies of Ser and Cys were 168 (97.7%), 4 (2.3%) in the bipolar disorders, 196 (98.0%), 4 (2.0%) in the controls. There were no differencies in genotype distribution and allele frequencies of dopamine D2 receptor gene polymorphism Ser311/Cys311 between in the bipolar disorders and in the controls. CONCLUSION: These result suggests dopamine D2 receptor gene polymorphism Ser311/Cys311 is not causally related to the development of bipolar disorder in korean population.

The purpose of this study is to analyze occupational history of coal miners with pnemoconiosis. In this study, occupational chracteristics of 49 coal miners with pneumoconiosis were compared with those of 45 coal miners without pneumoconiosis but in similar age category (43-52 years of age) based on interview survey. Various indices on occupational characteristics were developed for the following areas: duration of employment, perception of working condition, working density, dust concentration, temperature, humidity, and experience of respirator wearings. Perception of working condition were measured in 5 points scales but experiences of respirator wearing was measured in 3 points scale. Each index was multiplied by duration of employment. From the analysis, only the experience of respirator wearing showed statistically significant difference between the two groups. Therefore, respirator wearing seemed to be effective in reducing occurrence of pneumoconiosis.

In order to investigate working conditions of underground coal mines, this work was undertaken to evaluate the respirable dust and the concentration of quartz in Taeback and Kangneung areas. The concentration of quartz was determined by Fourier Transform Infrared Spectrophotometry. The results were as follows; 1) The concentration of respirable dust of drilling and coal face in Taeback and Kangneung areas were as followed. 2) Distribution of respirable dust was well fitted to the long-normal distribution and geometric mean value was log(-1) 0.37+/-log(-1) 0.47 (2.34+/-2.95) mg/m3. 3) The difference of respirable dust concentrations in Taeback and Kangneung areas was not significant statistically (p>0.05). 4) The concentration of quartz of drilling and coal face in Taeback and Kangneung areas were as followed. 5) Distribution of quartz concentrations was well fitted to the log-normal distribution and geometric mean value was log(-1) 0.33+/-log(-1) 0.45 (2.14+/-2.82)%. 6) The difference of quartz concentrations in Taeback and Kangneung areas was not significant (p>0.05), but significant at drilling sites and coal faces (p<0.05).

During the rehabilitation period, traumatic fracture of the lower extremity in chronic spinal cord injured patients may be occur frequently. In the past, conservative treatment with pillow or plaster splinting was advocated by many clinician, but its treatment is still controversial. This paper presents our experience with fracture of 20 patients(5.7%) of total 350 patients who had spinal cord injuries from Jan. 1980 to Mar. 1987 at Korea Veterans Hospital. The results were as follow. 1. The incidence of fracture was not related to age, sex, type and duration of spinal cord injury. 2. The most common cause of fracture was insignificant trauma(94%). 3. The distribution of fracture was in the following order of frequency;supracondyle of femur (20%), shaft of femur (20%), shaft of tibis (16%). 4. The methods of treatment-Twenty cases were treated by conservative treatment and eleven cases were treated by operative treatment in following order; paster splint with well padded; 9 cases (20%), pillow splint; 4 eases (13%), plate and screw; 3 cases (10%). 5. Total 11 cases of complications were 8 cases in conservative treatment and 3 cases in operative treatment. 6. The duration of bone union was average 10 weeks in nonoperative treatment and average 10.2 weeks in operative treatment. Treatment should strive to achieve fracture healing with minimal danger to the patient and should cause little or no interfrence with patient's daily routine.
