摘要:

Finger systolic blood pressure (FSBP) measurements after finger and body cooling using a strain-gauge plethysmograph is a useful objective test for diagnosing Raynaud's phenomenon (RP). Body cooling, however, is uncomfortable to subjects. In this study, the measurements of FSBP after finger cooling without body cooling, using Digitmatic DM2000 (Medimatic) combined with laser-Doppler flowmetry (ALF2100 Advance), were performed in 99 vibration-exposed men (40 men without RP, 39 men with mild RP, and 20 men with severe RP) and 13 healthy controls. This method is relatively useful for assessing the severity of vibration-induced white finger (VWF).

摘要:

Organic solvents probably exert their clinical effects through distortion of cellular membrane structure and function. Blood platelets represent an easily available membrane system. This study describes an evaluation of mean platelet volume (MPV) and total platelet count (TPC) in a group of workers exposed to a mixture of organic solvents in paint factories. We have founds a correlation between decreased MPV and present exposure. The education was reversed within an exposure-free interval of 3 weeks. The intracellular adenosine triphosphate/adenosine diphosphate (ATP/ADP) ratio was significantly increased in exposed workers, compatible with dense granule secretion. A quantitative study of the phosphoinositide cycle in the platelets revealed an increased concentration of the phosphatidic acid, indicating an increased turnover. These findings are consistent with a solvent-induced activation of circulating platelets.

摘要:

Reductions in workday cigarette consumption among indoor workers subject to different levels of smoking restriction were examined using representative population data for both blue-collar and white-collar workers. Regardless of whether workplace smoking bans were total or applied only to the usual work station, reported workday cigarette consumption was reduced by approximately five cigarettes per day compared with leisure-day consumption. This was in contrast to there being no difference between workday and leisure-day consumption among those who had no ban on smoking at their usual work station. This pattern of findings applied to all occupational-status groups, after controlling for sex and number of cigarettes smoked on a leisure day. These results are discussed with reference to potential public-health benefits and to implications for reduced retail sales of cigarettes.

摘要:

Little is known about the causes of health complaints associated with work with video display units (VDUs). The symptoms are to a large degree similar to those of “multiple chemical sensitivity.” We observed 47 white-collar employees with and without VDU-associated skin complaints during a regular workday and a day of leisure. VDU workers with skin symptoms had higher levels of the stress-sensitive hormones thyroxin and prolactin compared with employees without symptoms. They also had lower levels of the anabolic hormone testosterone during work. VDU workers with skin complaints also reported more occupational mental strain. A model is proposed in which physiological signals act as unconditioned stimuli and the VDU environment as the conditioned stimuli.
