Abstract PDF: OBJECTIVES
The chrome-induced olfactory alterations is caused by inhalation of chromic acid, a highly corrossive and toxic materials. And nasal septum perforation(NSP) has been suspected with possible causative factor of olfactory alterations. To our knowledge, there has been no report of the detailed findings of the olfactory alterations in chrome exposed subjects without nasal septum perforation(NSP). So we present the results of olfactory function test measured by T&T olfactometer and olfactometer perception test among chromium exposed workers without NSP.
METHODS
We performed this study in 25 study subjects and 25 control subjects matched with age, alcohol and smoking. All of subjects are man. We performed olfactory function test measured by T&T olfactometer and olfactometer perception test.
RESULTS
1) The age distribution of the subjects involved in this study was from 20 to 54 years old (average 33.3 years old) and the mean duration exposed to chromium was from 64. 9 months. 2) The olfactory function was checked by detection and recognition thresholds in five odorants. The detection thresholds of exposed group dealing with chromium were significantly increased in A and B ordorants than nonexposed group. The recognition thresholds of exposed group were significantly increased in D ordorants than nonexposed group. 3) The mean threshold of olfactometer perception test of exposed group were more increased than nonexposed group. But thresholds difference did not show statistical significance, 4) The detection thresholds of A and D ordorants, recognition threshold of C ordorants and thresholds of olfactometer perception test were increased in the relation with duration of chrome exposure.
CONCLUSIONS
There has been no remarkable alterations in olfactory sense (TkT olfactometer and Olfactometer Perception Test) in subjects without nasal septum perforation(NSP) exposed to chromic acid.

Quantitative Sensory and Vascular Tests in the Assessment of Hand-Arm Vibration Syndrome: Seung Wan Kang, Eun Il Lee, Yong Tae Yum, Hae Joon Kim; Korean Journal of Occupational and Environmental Medicine 1996;8(2):210-222. Published online September 30, 1996; DOI: https://doi.org/10.35371/kjoem.1996.8.2.210

This study was conducted on 103 male workers exposed to local vibration (exposure workers) and 23 male clergical workers not exposed to local vibration (reference workers) to evaluate the effect of local vibration in a automobile industry workers who had used vibratory tools such as electric bolt impacter or grinder. The assessment methods of this study were some tests recommended by Wasserman and Taylor. None of reference workers complained sensorineural symptoms, but 43.7% of exposed workers complained over one of those symptoms. The proportion of non-recovery type, which means that there was no full recovery of temperature of finger tips, was from 0% to 31. 3% in reference workers and from 10.7% to 15.5% in exposure workers. There was statistically significant difference of recovery time of plethysmogram after cold provocation between mean recovery time of 0.44 minutes in reference workers and that of 3.05 minutes in exposure workers. The proportion of bad plethysmogram was from 0% to 4.4% in reference workers and from 3.9% to 7.8% in exposure workers. There was statistically significant difference of discrimination sense between mean length of 2.04 mm in reference workers and that of 2.9 mm in exposure workers. There were also statistically significant difference of pain sense between mean weights of from 5.02 g to 5.26 g in reference workers and those of from 6.81 g to 7.6 g in exposure workers. By the results of multiple stepwise regression analysis the statistically significant variable affecting discrimination and pain sense was exposure and those affecting vibration sense were exposure and age. We concluded that exposure of local vibration in automobile workers was significaritly associated with decrease of sensorineural sense regardless of age and other, possible related variables.

Vibration Perception Threshold of Male Workers Exposed to Carbon Disulfide: Seung Hoi Park, Eun Il Lee, Byung Chul Chun, Yong Tae Yum, Jae Wook Chi; Korean Journal of Occupational and Environmental Medicine 1996;8(1):85-96. Published online February 29, 1996; DOI: https://doi.org/10.35371/kjoem.1996.8.1.85

Abstract PDF

This study was conducted on 367 male workers to evaluate the change of vibration perception threshold (VPT) according to exposure degree to carbon disulfide. VPT was measured on both metacarpal bones of index and little fingers and on fibular malleoli by Vibrometer (Rion, on 125Hz). The exposure degree was classified by the name of department. Workers in department 1 had been exposed to high concentration of carbon disulfide, those in. department 2 had been exposed to carbon disulfide moderately or intermittently, and those in department 3 had been exposed to undetectable concentration of carbon disulfide. The results were as follows: 1. The mean values of VPT of metacarpal(MC) bones showed dose-response pattern, i.e., the mean values of VPT at department 1 were highest, and those of VPT at department 3 were lowest with similar work duration or age. But the mean values of VPT of fibular malleoli (FM) showed dose-response pattern only in workers having above 5 years of work duration or whose age were above 30. 2. The mean values of VPT of MC bone of workers increased by age. 3. There were statistically significant difference in mean values of VPT of MC bone only in workers having 5-10 year work duration. And there were statistically significant difference of mean values of VPT of left 2nd and 5th MC bone in workers whose age was 30's, of right 2nd MC bone in those whose age was 40's, and of left 2nd MC bone in those whose age was 50's. 4. The variables affecting VPT significantly were department and age (or age group) both in multiple regression and general linear model. The department showed to have more effect to VPT than age in multiple regression, but age group showed to have more effect to VPT than department in general linear model. 5. The variables were transformed to indicator variable to do logistic regression analysis. Department 1, 2, 3 were classified into high exposure (spinning department) and low exposure (other department), age was classified into old (above 30) and young, and work duration was classified into long(above 10 years) and short. The exposure and age were significant variables by logistic regression analysis. Odds ratios of department and VPT on metacarpal bones or malleoli were 2.7-3.2 and those of age and VPT were 2.6 or 2.7. Odds ratio of age and abnormality of VPT on'any point was 3.3(1.59-6.;8), and that of department and VPT was 2.8(1.5-5.5). We concluded that exposure of carbon disulfied was significantly associated with reduction of VPT regardless of age; and that the test of VPT would be useful tool for screening and early detection in neuropathy by carbon disulfide or other neurotoxic chemicals,even though it is simple and cheap.

A Study on the Associatio Between Symptoms and Biological Indicies in Workers Exposed to Lead: Sung Bong Kim, Eun Il Lee, Kwang Jong Kim; Korean Journal of Occupational and Environmental Medicine 1990;2(2):199-205. Published online August 31, 1990; DOI: https://doi.org/10.35371/kjoem.1990.2.2.199

Abstract PDF: This research was conducted to determine the usefulness of reported symptoms for the diagnosis of lead poisoning for workers exposed to lead. A group of 147 male lead smelting workers were given special physical examinations from June to September of 1989. The examinations included the reporting of ailments(symptoms) by the workers, as well as analyses of their blood lead concentrations and urinary coproporphyrine and delta-aminolevulinic acid concentrations. the associations were analyzed between the bilogical exposure indices and the symptoms described by the workers. The results were as follows: 1. The only symptoms which were described more frequently by the lead workers compared to the control group were paresthesia of the extremities, myalgia, arthralgia, and insomnia. The frequency of other symptoms described were actually lower for the lead-exposed workers. 2. For those workers whose blood lead concentrations were above 60 microgram/dl, only the increase in the frequencies of arthralgia and paresthesia of the xtremities were statistically significant, compared to those workers whose blood lead concentrations were below 60 microgram/dl. Also, arthralgia was the only symptom which increased in frequency in workers whose ruinary coproporphyrine concentrations were above 100 microgram/l; however, this increase was not statistically significant by urinary delta-aminolevulinic acid levels.
