Bradykinin, angiotensin II, arginine vasopressin (AVP) or des-amino-D-arginine vasopressin (DDAVP) were administered by intravenous infusion to 10 healthy men. The concentration of 6-oxo-prostaglandin F1 alpha (6-oxo-PGF1 alpha), the stable hydrolysis product of prostacyclin (PGI2), was measured in plasma using gas chromatography/negative ion chemical ionisation mass spectrometry. Dose-related increases in plasma concentrations of 6-oxo-PGF1 alpha occurred during administration of bradykinin (100-3200 ng kg-1 min-1). The concentrations of 6-oxo-PGF1 alpha rose from baseline values in the range less than 1.0-4.9 pg ml-1 to 24.9-47.6 pg ml-1 at maximum tolerated infusion rates. There were no changes in the concentrations of 6-oxo-PGF1 alpha during administration of angiotensin II, AVP or DDAVP at infusion rates which caused haemodynamic changes.
对10名健康男性静脉输注缓激肽、血管紧张素II、精氨酸加压素(AVP)或去氨基-D-精氨酸加压素(DDAVP)。使用气相色谱/负离子化学电离质谱法测定血浆中前列环素(PGI2)的稳定水解产物6-氧代-前列腺素F1α(6-氧代-PGF1α)的浓度。在输注缓激肽(100 - 3200 ng kg-1 min-1)期间,血浆6-氧代-PGF1α浓度出现剂量相关的增加。在最大耐受输注速率下,6-氧代-PGF1α的浓度从基线值(范围小于1.0 - 4.9 pg ml-1)升至24.9 - 47.6 pg ml-1。在引起血流动力学变化的输注速率下,输注血管紧张素II、AVP或DDAVP期间,6-氧代-PGF1α的浓度没有变化。
