Two hundred and ninety-five male Finnish concrete reinforcement workers, aged 19 to 64 years and engaged in heavy physical work including prolonged stooping, were radiologically examined by antero-posterior and lateral views of the lumbar spine while they were standing. The findings of lumbar disc degeneration were classified as none, slight, moderate or severe. The prevalence and degree of radiologically detectable lumbar disc degeneration depended strongly on age and increased especially rapidly ...

It is known from industrial experience and experimental studies that percutaneous absorption of concentrated liquid solvents may be considerable and even hazardous if large enough areas of skin are exposed for long periods of time. Percutaneous penetration of xylene, styrene, toluene, 1,1,1-trichloroethane and tetrachloroethylene vapors at ambient air concentrations of 600 ppm for 3.5 h was studied in a dynamic exposure chamber with a restricted number of human volunteers. Although the small number ...

Occupational xylene exposure in the breathing zone of 15 painters was measured during three consecutive workdays. The applicability of the use of different biological samples was tested by the monitoring of xylene concentrations in blood and exhaled air, and urinary methylhippuric acid excretion as well. The best relation to the time-weighted average of xylene exposure was obtained for urinary methylhippuric acid concentration at the end of the workday; an amount of 665 mg/g of creatinine corresponded ...

Two hundred and ninetyfive male Finnish concrete reinforcement workers, aged 19-64 years and engaged in heavy physical work including prolonged stooping, were clinically examined in a cross-sectional study. A history of sciatica was reported by 42% of the men, and a history of lumbago by 33%. The prevalence of the reported experience of sciatica and lumbago doubled in the two decades from age 25-34 onward. Half of those with a history of sciatica had also experienced lumbago; two-thirds of those ...

Studies were made using ordinary selective coronary angiography and angiography during ischaemia produced by right atrial pacing, on a series of 41 patients with ischaemic heart disease, to examine the response of the collaterals to the ischaemia stimulus. Regional myocardial perfusion was determined under the same circumstances by measuring regional 133Xenon washout curves. No collaterals were found in 8 patients, none of whom demonstrated collaterals when angiography was repeated during ischaemia. ...

Inhalation exposure to m -xylene at 100–400 ppm caused some changes of psychophysiological performance of volunteer subjects, e.g. impairment of body balance and increase of reaction times. With repetitive exposure, tolerance developed within a few days with regard to most of these effects. At steady-state and under conditions of increased xylene absorption, blood xylene concentration was directly related to the rate of xylene uptake. Acute xylene effects on the central nervous system were correlated ...

Ten healthy male volunteers were exposed for 4 h to two concentrations [6 and 11.5 mumol/l (636 and 1,218 mg/m3)] of m-xylene or/and given single doses (0.4 and 0.8 g/kg) of ethyl alcohol. Exposure to two xylene concentrations combined with the higher dose (0.8 g/kg) of alcohol was also conducted. Vestibular functions (positional nystagmus with electronystagmography, body balance) and visual function (flicker fusion) were measured. Both alcohol doses increased body sway and the intensity of nystagmus ...

Ingestion of benzoic acid (intermediary metabolite of toluene) by one volunteer subject indicated that the maximum urinary excretion rate of hippuric acid (final metabolite of toluene) was about 190 µmol/min. An almost identical figure for the saturation kinetics of hippuric acid formation has been reported in the literature, and it has been shown to be limited by the availability of glycine for benzoic acid conjugation. The maximum excretory capacity of the kidneys for hippurate is known to be considerably ...

Sedentary volunteer subjects were exposed to an m-xylene concentration of about 3.9 mmol/m3 over five successive days, 6 h/d. It was noted that about 60% of the inhaled xylene was retained in the lungs. The estimated daily uptake of xylene was recovered nearly quantitatively as methylhippuric acid in the urine. Other pathways of xylene excretion played a minor role. The rate of 2,4-xylenol excretion shortly after a day's exposure was about 1-2% of that for methylhippuric acid excretion, and pulmonary ...

Xylene is a common solvent and thinner in paints and varnishes, and it is frequently accompanied by other types of solvents, for instance, isobutyl alcohol. Percutaneous absorption of xylene was studied under conditions in which both hands were immersed once for 15 min in pure m-xylene, in a mixture of equal parts of m-xylene and isobutanol, and in a 1 : 1 mixture of m-xylene and isobutanol saturated with water. Estimates for absorption were derived from the postexposure urinary and pulmonary excretion ...

The three types of exposure were identical in that the time- ...

Some recent epidemiologic studies have suggested that chlorinated phenoxy acid herbicides are human carcinogens. The mortality experience in a cohort of 1,926 men who had sprayed 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) during 1955-1971 has been followed prospectively from 1972 to 1980. The total phenoxy acid exposure was generally rather low because the duration of work had mostly been less than two months. In 1972-1976 mortality from all natural causes ...

Acute ethanol ingestion inhibits the metabolism of the common industrial solvents trichloroethylene and dimethylformamide. The solvents in turn may interact with ethanol metabolism as shown by an accumulation of acetaldehyde and occasional symptoms of alcohol intolerance. It was recently found that mutual metabolic interaction occurs even in the context of ethanol ingestion (0.8 g/kg in single dose) combined with subsequent inhalation exposure to m-xylene (6.0 & 11.5 mmol/m3 (140 & 280 ppm), over 4 h). ...
