  • RENAL VASCULAR HYPERTENSION DOES NOT LEAD TO HYPERINSULINEMIA IN SPRAGUE-DAWLEY RATS AMERICAN JOURNAL OF HYPERTENSION Reaven, G. M., Ho, H. 1992; 5 (5): 314-317

    Abstract:

    The effect of renal vascular hypertension on blood pressure and plasma glucose, insulin, and triglyceride concentration was studied in Sprague-Dawley rats. Three weeks after the induction of renal artery sterosis, mean (+/- SEM) blood pressure was significantly greater (153 +/- 3 v 117 +/- 2 mm Hg, P less than .001) compared with that in sham-operated rats. However, the two groups were similar in terms of plasma glucose (140 +/- 3 v 140 +/- 2 mg/dL), insulin (27 +/- 3 v 23 +/- 2 microU/mL), and triglyceride (89 +/- 8 v 95 +/- 6 mg/dL) concentrations. Furthermore, blood pressure increased to a similar degree in the two groups of rats (22 +/- 4 v 24 +/- 2 mm Hg), as did plasma insulin (47 +/- 5 v 44 +/- 4 microU/mL) and triglyceride (407 +/- 50 v 381 +/- 46 mg/dL) concentrations, after 2 weeks of a high-fructose diet. These data indicate that experimental induction of renal vascular hypertension in normal rats was not associated with an increase in either plasma insulin or triglyceride concentration. Furthermore, the response of rats with renal vascular hypertension to a high-fructose diet was similar to that of the sham-operated group. These data support the view that hypertension, per se, does not lead to hyperinsulinemia and hypertriglyceridemia in normal rats.
