摘要: 目的 研究四甲吡嗪(川芎嗪, Lig) 对白细胞呼吸爆发期间氧消耗和过氧化物的影响。方法 采用电子自旋共振自旋捕集技术, 自旋探针氧测定法和化学发光法检测白细胞呼吸爆发期间氧消耗和活性氧自由基。结果 Lig 对白细胞呼吸爆发期间的氧消耗无明显影响(P >0.05), 但能明显抑制其产生的化学发光(P <0.01), 这是Lig 清除$\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$和OH·的结果。结论 Lig 可以不抑制白细胞氧化代谢的功能而通过清除氧自由基防止白细胞对组织的损伤。

Abstract: Aim To investigate the influence of tetramethylpyrazine (ligustrazine, Lig) on oxygen consumption and superoxide during the respiratory burst of human neutrophils. Methods It was observed by using ESR spin trapping, spin probe oxymetry and lumino-dependent chemiluminesence (CL). Results Lig had no influence on oxygen consumption during the respiratory burst of neutrophils (P > 0.05) but had remarkable inhibition on CL response generated by neutrophils (P <0 01), and had scavenging effect on $\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$ and OH ° generated by neutrophils, which were demonstrated in xanthine/xanthine oxidase system and Fentons reaction(P <0.01). Conclusion Lig has no inhibiting effect on oxygen metabolic function of neutrophils, but protects tissue from injury caused by activated neutrophils through scavenging oxygen radicals.
