Well-defined areas of the mesentery were superfused during 3 s with 300 microliters of hypertonic NaCl solution, while monitoring the electrophysiological response of the hypothalamo-neurohypophysial tract. Response magnitudes were largest for superfusion of the portal, the duodenal and jejunal mesenteric veins, and least for superfusion of the mesenteric vessels of the ileum. The results suggest the existence of peripheral receptors that appear to be strategically located to monitor the intestinal absorption of salt or water.
在监测下丘脑 - 神经垂体束的电生理反应时，对肠系膜的明确区域在3秒内灌注300微升高渗氯化钠溶液。门静脉、十二指肠和空肠系膜静脉灌注时反应幅度最大，回肠系膜血管灌注时反应幅度最小。结果表明存在外周受体，这些受体似乎处于关键位置，以监测肠道对盐或水的吸收。
