||In order to study the effect of noise and vibration on the medullo-adrenal and sympathetic systems, the authors examined 80 mechanical engineering workers exposed to noise and vibration and 20 controls; they determined vanillic-mandelic acid (VMA), 17-ketosteroids (17-KS) and creatinine in urine. After 4h of work, exposed workers were found to have a 28% increase in VMA and a 14% reduction in 17-KS. Following 8h of night rest, there was a 15% fall in VMA in comparison with the controls; there was a similar reduction in 17-KS. This shows that, in exposed subjects, recuperation of cell-energy potential does not follow immediately upon the cessation of noise and vibration exposure, due to inadequate endocrine irrigation. Consequently it is necessary to arrange work breaks accordingly and to ensure suitable rest after work.
