Result:① In NC group,the levels of plasmic and lymphocytic NO were higher in the morning than those in the afternoon.② The plasmic and lymphocytic NO were significantly decreased in CAD patients then those in NC group (P＜0.01).③The physiological NO curve disappeard in CAD patients.The concentrations were no obvious changes and maintained lower levels in 24 hours.Conclusion:As similar as other endocrinic hormones,the NO secretion was not equal in 24 hours.

结果：①正常人24 h血浆和淋巴细胞中NO分泌呈上午高、下午低的趋势，晨6时最高，下午6时呈低谷，晚10时起又渐升高至早晨；②CAD心绞痛患者血浆和淋巴细胞中NO含量明显低于正常人，其差异具有统计学意义(P＜0.01)；③CAD患者失去了正常的NO生理性分泌曲线，血浆和淋巴细胞中24 h均在较低水平，波动范围不大。
