糠醛是石油化工工业常用的溶剂和中间体 ,用于提炼石油、润滑油以及橡胶、塑料制造等 ,也广泛存在于人们的生活环境中。研究表明〔1〕,石油化工生产过程充满了自由基反应 ,许多化工毒物可通过影响细胞内活性氧系统而导致细胞的氧化性损伤 ,被认为是化学中毒的重要机理之一。糠 Furfural is a commonly used solvents and intermediates in the petrochemical industry. It is widely used in people’s living environment for refining petroleum, lubricating oil, rubber and plastics. Studies have shown that [1], petrochemical production process is full of free radical reactions, many chemical toxicants can affect the cellular reactive oxygen species and lead to oxidative damage of cells, is considered to be one of the important mechanisms of chemical poisoning. bran
