Alkoxyethanols (ethylene glycol alkyl ethers) are used as mixtures in a variety of industrial and household products. The aim of this study has been to evaluate the effects of 2-methoxyethanol (ME) and 2-ethoxyethanol (EE) on hematological changes induced by 2-butoxyethanol (BE) in rats.
Experiments were performed on male Wistar rats treated subcutaneously with BE, ME, and EE alone (in the dose of 0.75 mM/kg/day and 1.25 mM/kg/day) and their mixtures with the molar ratio 1:1, for 4 weeks. Hematological analyses were performed on the day 0, 4, 11, 18, and 29. Hemoglobin (HGB) concentration in the urine was also determined in the rats treated with BE alone and co-exposed to BE and ME and also BE and EE.
The rats co-exposed to BE and ME or BE and EE demonstrated significantly less pronounced hematological changes in comparison with animals treated with BE alone at the beginning of exposure. At the later period the hematological alterations in the same animals were markedly pronounced and progressing with exposure time. The rats co-exposed to BE and ME or BE and EE did not demonstrate hemoglobinuria.
ME or EE co-administered to rats with BE lead to the amelioration in the majority of the hematological parameters at the beginning of the exposure. The hematological changes at the end of the co-exposure to BE and ME or BE and EE were markedly pronounced. The effects observed in this study appear to be related with metabolic interactions of the examined ether. Med Pr 2015;66(3):303-315.
烷氧基乙醇(乙二醇烷基醚)在各种工业和家用产品中以混合物形式使用。本研究的目的是评估2 - 甲氧基乙醇(ME)和2 - 乙氧基乙醇(EE)对大鼠中2 - 丁氧基乙醇(BE)诱导的血液学变化的影响。
对雄性Wistar大鼠进行实验,分别皮下注射单独的BE、ME和EE(剂量为0.75 mM/kg/天和1.25 mM/kg/天)以及它们摩尔比为1:1的混合物,持续4周。在第0、4、11、18和29天进行血液学分析。还测定了单独用BE处理以及同时暴露于BE和ME或BE和EE的大鼠尿液中的血红蛋白(HGB)浓度。
与仅用BE处理的动物相比,同时暴露于BE和ME或BE和EE的大鼠在暴露开始时血液学变化明显不那么显著。在后期,相同动物的血液学改变明显且随着暴露时间进展。同时暴露于BE和ME或BE和EE的大鼠未出现血红蛋白尿。
与BE共同给予大鼠的ME或EE在暴露开始时导致大多数血液学参数得到改善。同时暴露于BE和ME或BE和EE结束时的血液学变化明显显著。本研究中观察到的效应似乎与所检测醚的代谢相互作用有关。《医学实践》2015年;66(3):303 - 315。
