Some monoepoxides of linoleic acid (LA) were converted to monochlorohydrins in low-pH solutions containing chloride ions (Cl-). Conversely, monochlorohydrins of LA were converted to monoepoxides in high-pH solutions. We attempted to determine whether these monochlorohydrins and monoepoxides were produced from LA by the cytochrome-c-H2O2-and/or myeloperoxidase-H2O2-system. The existence of monoepoxides and monochlorohydrins of LA in leukocytes was confirmed by high-performance liquid chromatography (HPLC). Furthermore, leukotoxin in human leukemia cells (THP-1) was stained immunohistochemically by a monoclonal anti-leukotoxin antibody.
一些亚油酸(LA)的单环氧化物在含有氯离子(Cl-)的低pH溶液中转化为单氯醇。相反,LA的单氯醇在高pH溶液中转化为单环氧化物。我们试图确定这些单氯醇和单环氧化物是否由细胞色素c-H2O2-和/或髓过氧化物酶-H2O2-系统从LA产生。通过高效液相色谱法(HPLC)证实了白细胞中LA的单环氧化物和单氯醇的存在。此外,人白血病细胞(THP-1)中的白细胞毒素用单克隆抗白细胞毒素抗体进行免疫组织化学染色。
