The effect of nephrectomy and ureter ligation on plasma neurotensin-like immunoreactivity levels in the conscious rat
Abstract
The effect of nephrectomy and ureter ligation on the concentration of endogenous plasma neurotensin-like immunoreactivity (p-NTLI) was studied in conscious rats by means of antiserum 17-8201 which detects NT (1-13) only, and antiserum 0-7709 which detects NT(1-13) and NT(1-8). The unstimulated p-NTLI concentration did not change significantly during a 25-h observation period following nephrectomy in comparison with sham operation. However, stimulation of the release of NTLI by intraduodenal administration of oleic acid (0.2 ml) resulted in significantly higher p-NTLI levels in the nephrectomized rats than in the sham operated rats. Ureter ligation did not significantly affect basal or stimulated p-NTLI. The data indicate that the kidneys play an important part in the elimination of p-NTLI released after fat ingestion.
