Plasma renin activity (PRA) was measured after repetitive furosemide stimulations in 16 normotensive homotransplanted patients who previously had bilateral nephrectomies. The percentage PRA response to furosemide was very low (34%) in the immediate period after transplantation, but increased progressively with time to a level after one year (111%) which was not statistically different from age and sex matched control subjects. A significant correlation was found between the percentage PRA increase and the number of weeks after transplantation (r = 0.48, P less than 0.01). These data indicate that the juxtaglomerular cell responsiveness to furosemide is quantitatively time dependent after transplantation, and it is a factor that should be considered in the evaluation of renin-angiotensin system in such patients.
对16例曾行双侧肾切除术的血压正常的同种肾移植患者,在反复给予速尿刺激后测定血浆肾素活性(PRA)。移植后即刻,PRA对速尿的反应百分比非常低(34%),但随时间逐渐升高,至一年后达到一个水平(111%),与年龄和性别匹配的对照受试者相比无统计学差异。发现PRA升高百分比与移植后周数之间存在显著相关性(r = 0.48,P < 0.01)。这些数据表明,移植后肾小球旁细胞对速尿的反应性在数量上与时间相关,这是评估此类患者肾素 - 血管紧张素系统时应考虑的一个因素。
