Abstract

Lack of Relationship between Occupational Exposure to Carbon Disulfide and Endocrine Dysfunction: A Six‐year Cohort Study of the Japanese Rayon Workers: Toru Takebayashi, et al.Department of Preventive Medicine and Public Health, School of Medicine, Keio University A six‐year prospective cohort study was conducted to clarify whether the current carbon disulfide (CS2) exposure level is low enough to prevent subclinical health impairment and/or to ameliorate health effects due to previous high exposure. This paper describes the follow‐up results, exposure assessment, and effects on the endocrine system. The study subjects were 432 male workers exposed to CS2at one of the 11 rayon factories in Japan and 402 referent workers from the same factories, all of whom were examined in 1992–93. 251 CS2exposed, 140 former‐exposed and 359 referent workers participated in the follow‐up survey (follow‐up rate 89.9%) in 1998–99. Urinary 2‐thiothiazolidine‐4carboxylic acid (TTCA) at the end of a shift as internal exposure index and the time‐weighted average CS2concentration as external exposure index were measured twice a year from 1992–1993. By using various blood indices, we evaluated effects on thyroid, hypophysis, and gonad function, as well as effects on glucose metabolism. Information on potential confounding factors, such as age, smoking and alcohol drinking, were collected and adjusted for. When the individual exposure level was represented by arithmetic mean for TTCA and CS2concentration, geometric means (SD) of CS2workers were 1.61 (1.91) mg/g.crea and 5.02 (1.84) ppm, respectively. There were no exposure‐related differences in glucose metabolism or any of the endocrinological indices. Conclusions—No biologically significant effects of CS2were found on endocrine function in Japanese rayon manufacturing workers when the average internal and external exposure levels were maintained below the current occupational exposure limit.

21. In VitroSolubility and In VivoToxicity of Indium Phosphide

Abstract

In VitroSolubility and In VivoToxicity of Indium Phosphide: Isamu Kabe et al.Department of Preventive Medicine and Public Health, School of Medicine, Keio University—This study was designed to clarify the in vitrosolubility and the in vivobasic toxicity of indium phosphide (InP). InP powder was clearly soluble in synthetic gastric fluid and quite insoluble in saline or synthetic lung fluid. Male ICR mice (SPF grade) were given InP at the doses of 0, 1,000, 3,000, and 5,000 mg/kg, intraperitoneally (i. p.) or orally (p. o.). During a 2‐week observation, no mice died. In i. p. treated mice, the serum indium concentration showed a dose‐dependent increase, and indium mainly accumulated in the lungs and liver. Dose‐dependent increases in lung and spleen weight were observed. Black granules of InP were deposited in the lymph nodes, spleen, lungs, and liver. Extramedullary granulopoiesis was observed. And eosinophilic exudates and mononuclear cells were seen in the pulmonary alveoli. Considering these findings, InP particles were presumably transferred to the spleen, liver, and lungs by way of lym‐ phokinetics, causing reticuloendothelial responses. Hematological examination showed increased proportions of stab cells and monocytes in 5000 mg/kg i.p. dosed mice. The p. o. administered mice showed no clear relationship between the dose and biological effects.

Abstract

Objectives: To test the reliability of the procedures (described in a previous article) for estimation of biological occupational exposure limits (BOELs)., Methods: Data on four organic solvents (styrene, ethyl benzene, isopropyl alcohol and tetrachloroethylene) were obtained from recent publications and added to previously cited data for 10 organic solvents. Regression analysis was used for statistical evaluation., Results and Discussion: The previously reported results obtained using 10 solvents were reproduced by the analysis with 14 solvents. Repeated randomized division of the 14 sets into two subgroups of equal size followed by statistical comparisons did not show a significant difference between two regression lines. This reproducibility suggests that the procedures used to estimate BOELs may be applicable across many solvents, and this may be of particular benefit for protecting the health of workers who work with skin-penetrating solvents.
