During the work period, occipital midline beta-2 (Oz beta 2) amplitude, urinary adrenaline (A) and noradrenaline (NA) excretion, heart rate (HR), blood pressure (BP), subjective rating of tiredness (SRT), and subjective symptoms of fatigue (SSF) were higher than those during the rest period. Oz beta 2 amplitude, diastolic pressure (DP), critical flicker fusion value (CFF), and performance level (number answered, percent correct) remained unchanged over the rest/work period. Moreover, A and NA excretion, HR, and systolic pressure (SP) changed parallel with their resting level. With the lapse of working hours, SRT and SSF elevated. These results suggest that performance of calculating task causes mental stress which remains constant throughout the work period and that subjective fatigue increases with extension of working hours.","PeriodicalId":21500,"journal":{"name":"Sangyo igaku.

Exposure to all the TRI levels significantly decreased amount of time spent in wakefulness (W) during the exposure period. Exposure to 100 ppm and higher levels significantly decreased the time-averaged HR during the post-exposure period. The HRs during the stages of slow-wave sleep (SWS) and paradoxical sleep (PS) were significantly lowered after cessation of exposure to 50 ppm. When compared with the previously reported responses to short-term exposure to TRI (Arito H, et al. Arch Toxicol 1993; 67: 193-199), significant changes in wakefulness-sleep and HR elicited by the long-term exposure appeared at lower exposure levels. The EEG and HR effects of long-term exposure to TRI of 50 ppm or higher levels are discussed for their causative factors on the basis of the reported findings and for validity of the ongoing biological exposure limit value of TRI with reference to documentations enlisted for ACGIH's TLV of 50 ppm (ACGIH. Documentation of the threshold limit values and biological exposure indices, 5th ed. 1986: 595-597).","PeriodicalId":21500,"journal":{"name":"Sangyo igaku.

Sudden death was defined as internal death within 24 hours from the onset of the event. Two controls whose sex and age were matched with a case were selected from the employees of the company. The risk factors studied were age, sex, obesity, blood pressure, serum glucose, total cholesterol, triglyceride, uric acid, urinary, protein, urinary sugar, electrocardiographic (ECG) findings, diabetes mellitus, smoking history and drinking history. These data were collected from the latest health care record including health examinations performed annually in the company. t test, U test and Fisher's test were applied to each of the variables. Multiple logistic regression analysis and canonical discriminant analysis were applied, using mean systolic blood pressure for 5 years, body mass index (BMI), abnormal Q wave on ECG, and serum glucose as explanatory variables. From 1984 to 1990 44 sudden death cases composed of 42 males and two females were identified. The age-specific mortality rate increased exponentially with age with a peak at the sixth decade. The most frequent cause of sudden death was heart disease (77%) followed by cerebrovascular disease (18%). Statistical analysis showed that significant risk factors were high blood pressure, low BMI, diabetes mellitus, and ST-T change on ECG.","PeriodicalId":21500,"journal":{"name":"Sangyo igaku.

An exploratory case-control study was conducted on parents of children less than 15 yr of age with acute lymphocytic leukemia (ALL). Data were obtained on 147 identified cases by interview from their mothers and by mail questionnaire from their fathers. Hospital control cases were matched by sex and age, while population control cases were matched by place of residence, and sex. The following results were obtained. 1) As for the occupation of the parents, more fathers of the cases were engaged in occupations related to agriculture, medicine, and science than those of the controls, and more mothers of the cases were engaged in agriculture than those of the controls. 2) No significant relation could be demonstrated between ALL and occupations related to hydrocarbon and ionizing radiation. 3) The results of multivariate analysis showed that in comparison with the hospital control cases the preconceptual exposure to chemicals and the prenatal exposure to pesticides of the fathers and the prenatal exposure to benzine and spray pesticides of the mothers were risks of high significance. In comparison with population control cases, the prenatal exposure of benzine and exposure to paints of the mothers prior to disease onset were risks of high significance. The foregoing results suggest that exposure to occupational and environmental factors of the parents may play an etiologic role in childhood leukemia.","PeriodicalId":21500,"journal":{"name":"Sangyo igaku.
