【摘要】 本文研究了工人接触低浓度二硫化碳对周围神经传导速度的影响。结果表明,在国家容许浓度10mg/m~3范围内,接触组正中神经、尺神经运动传导速度与对照组比,无明显区别,提示,就神经传导速度而言,10mg/m~3是安全的容许浓度。更多还原

【Abstract】 Studied in this paper were theeffects of Carbon disulphide （CS₂）at low concentration on peripheralnerve conduction velocities （NCV）.In three workshops of Shanghai No.12 Rayon Staple Factory,44 wor-kers （all males） were chosen as aexposure group with the mean oftheir age being 37.39±9.79.47 malesubjects not exposed to any toxicagents were used as a control group,their mean age being 38.02+12.39. CS₂ level of three workshopsfrom 1979 to 1983 were almost with-in the range of maximum allow-able concentration（MAC）,10 mg/m³,except for the level in 1979.Themeasurement of NCV showed:l)TheNCV between exposure and controlgroup was not significantly diffe-rent.2)The NCV didn’t significant-ly vary with the length of expos-ure time.3)There was no statisticdifference in NCV between the expo-sure groups of the different kindsof workshops and the controlgroup. The above results indicated thatthe adverse effects of CS₂ withinMAC on NCV were not observed, ??suggesting that,so far as NCV wasconcerned,the current MAC,10mg/m³,was safe.更多还原
