An analysis on the effect of nerve growth factor in treating peripheral neuropathy caused by chronic n - hexane poisoning 神经生长因子治疗慢性正己烷中毒周围神经病效果分析
Methods : the occupational health status were investigated in enterprise which n - hexane were used , and the concentration of n - hexane in the workplace was monitored and the occupational physical examination was conducted for workers 方法:编制职业卫生调查表,逐条对企业职业卫生现状进行调查,并对工作场所空气中正已烷浓度进行监测及部分企业员工开展职业性健康检查。
The analytical method for five pesticide residues of pyrethroid , such as fenpropathrin , cypermethrin , fenvalerate , deltamethrin and bifenthrin in potable water and source water determination by capillary gas chromatography at the same time , with n - hexane for extracting agent 摘要以正己烷为萃取剂,采用毛细管气相色谱法同时测定生活饮用水及水源水中甲氰菊酯、氯氰菊酯、氰戊菊酯、溴氰菊酯和联苯菊酯五种拟除虫酯类农药残留量。
No probe leakage was found when the sensor dipped in ethanol and n - hexane for 15 days . this technique is limited for its prolix procession and request of special active function in the structure of molecular probe , sol - gel : the development of sol - gel technique provides a convenient way to incorporate molecular probe in porous inorganic material 化学键合法:分子探针通过化学反应键合于固定相,在溶剂中不泄漏,提高了传感器使用寿命,在乙醇和正己烷中浸泡15天,未见探针分子泄漏。但繁杂的过程和对探针分子结构的特殊要求限制这一方光纤化学传感器、仪器系统的研制们比生物和环境监测中的应用(摘要) 2法的应用。
Results : 47 enterprises were using n - hexane and 554 workers exposure to n - hexane ; the concentration of n - hexane in 3 enterprises were exceeded the occupational exposure limit ; achilles ' s tendon reflex of 3 workers were disappeared ; and most of enterprises lacked of occupational health management and protection measures 结果:昆山市共有47家企业使用正已烷,接触人数共554人;有3家企业正已烷浓度超标;职业性健康检查人数共54人,其中有3人腱反射减退或消失;多数企业职业卫生管理和防护措施落实不到位。
