摘    要:采用PVP/Pd/IrO_2/Nafion修饰电极对成纤维细胞中NO的释放情况进行了研究 。结果表明,在正常状态下,采用NO前体L-精氨酸和乙酰胆碱对成纤维细胞进行刺 激后没有NO的释放;当用脂多糖进行诱导后,则释放出高浓度的NO,加入L-精氨酸 和乙酰胆碱都促进了NO的合成,而L-NNA的加入则逆转了L-精氨酸和乙酰胆碱的作 用。

关 键 词:  氧化铱  化学修饰电极  一氧化氮  精氨酸  乙酰胆碱

Abstract:PVP/Pd/IrO_2/Nafion microsensor was fabricated to measure nitric oxide production in fibrocytes directly. In the experiments, fibrocytes did not release nitric oxide after stimulated with L- arginine and acetylcholine under normal condition. After induced with lipopolysaccharide, NO was produced in high concentration and NO levels were increased after stimulated with L-arginine and acetylcholine. On the other hand, L-N~w-nitro-arginine, an NO synthase inhibitor, decreased the action of L-arginine and acetylcholine.
Keywords:fibrocytes   PVP/Pd/IrO 2/Nafion modified electrode   nitric oxide
