毒理性
鉴定和使用:Nonacosane 是一种含有29个碳原子(C29)的高级正构烷。人类暴露和毒性:一份病例报告描述了一个人类疾病的特征,即植物长链正构烷在人体内脏中的积累。弥漫性内脏肉芽肿含有亲脂性结晶物质,显示了长链正构烷的存在,包括n-Nonacosane。对患者组织中正构烷分布的研究表明,主要积累在腰主动脉淋巴结、肾上腺、肺和肝;在心肌和肾脏中检测到的量显著较低,而在大脑中没有检测到可检测水平。动物研究:Nonacosane 可导致牛的“石蜡肝”。牛肝脏中异常物质的大量存在表明毒性较低,显然是在长时间内积累的。
IDENTIFICATION AND USE: Nonacosane is a higher n-alkane containing 29 carbon atoms (C29). HUMAN EXPOSURE AND TOXICITY: A case report described human disorder characterized by the accumulation of plant long-chain n-alkanes in viscera of a human patient. Diffuse visceral granuloma containing lipophilic crystallized material showed the presence of long-chain n-alkanes including n-nonacosane. Study of n-alkane distribution in patient tissues showed a major accumulation in lumbo-aortic lymph nodes, adrenal glands, lung and liver; significantly lower amounts were detected in myocardium and kidney, whereas no detectable level was found in brain. ANIMAL STUDIES: Nonacosane can contribute to the "paraffin liver" in cows. The very large quantities of the abnormal substance in the cow livers indicate low toxicity, and evidently accumulation over long periods of time.
