关于心房钠尿因子(ANF)是否仅通过增加肾小球滤过率(GFR)来增加肾脏溶质排泄,或者是否直接抑制肾小管转运(与流速的变化无关)仍存在争议。自由流动微穿刺技术用于 10 只慕尼黑威斯塔大鼠。 ANF 导致单肾单位和全肾 GFR 显着增加(分别为 41.6 +/- 1.4 至 52.7 +/- 2.3 nl/min 和 0.95 +/- 0.05 至 1.24 +/- 0.09 ml/min)。尽管绝对近端钠、碳酸氢盐和氯重吸收增加,但重吸收的增量小于负荷的增加;因此,从近端小管输送出的溶质增加了约 30-35%。全肾电解质排泄量也显着上升。当单肾单位和全肾 GFR 通过主动脉缩窄降至对照水平(分别为 40.2 +/- 1.8 nl/min 和 0.93 +/- 0.05 ml/min)时,尽管持续施用 ANF,近端转运仍恢复到正常值。当 GFR 正常化时,90% 的 ANF 引起的尿钠和尿氯同时消失。总之,ANF 对浅表近曲小管的重吸收没有直接影响,与滤过率的变化无关。尽管不排除对更远端或更深肾单位段的直接影响,但目前的数据表明,ANF 主要通过急剧增加 GFR 来增加肾脏溶质排泄。
Controversy persists on whether atrial natriuretic factor (ANF) raises renal solute excretion simply by increasing glomerular filtration rate (GFR) or whether it directly inhibits tubular transport (independent of changes in flow rate). Free-flow micropuncture techniques were used in 10 Munich-Wistar rats. ANF caused a significant increase in single-nephron and whole-kidney GFR (41.6 +/- 1.4 to 52.7 +/- 2.3 nl/min and 0.95 +/- 0.05 to 1.24 +/- 0.09 ml/min, respectively). Although absolute proximal sodium, bicarbonate, and chloride reabsorption increased, the increment in reabsorption was less than the increase in load; therefore solute delivery out of the proximal tubule increased by approximately 30-35%. Whole-kidney electrolyte excretion also rose markedly. When single-nephron and whole-kidney GFR were reduced back to a control level by aortic constriction (40.2 +/- 1.8 nl/min and 0.93 +/- 0.05 ml/min, respectively), proximal transport reverted to normal values despite persistent ANF administration. Ninety percent of the ANF-induced natriuresis and chloruresis were simultaneously abolished when GFR was normalized. In conclusion, ANF has no direct effect on reabsorption in the superficial proximal convoluted tubule independent of changes in filtration rate. Although direct effects on more distal or deeper nephron segments are not precluded, the present data suggest that ANF can increase renal solute excretion predominantly by acutely augmenting GFR.
