Milan normotensive rats, which spontaneously develop marked proteinuria (PU) and glomerulosclerosis (GS), were either kept on a normal-protein diet, a normal-protein diet with additional low-dose captopril (CAP), which did not affect blood pressure, or on a low-protein diet. After 8 months PU (79 +/- 25 mg/day) GS (3 +/- 2%) and total glomerular volume (TGV; 27.9 +/- 2.9 mm3/kidney) were significantly lower (p < 0.05) in the low-protein diet group than in both the normal-protein group (PU 583 +/- 210 mg/day, GS 12 +/- 5%, TGV 34.6 +/- 8 mm3/kidney) and the low-CAP group (PU 611 +/- 224 mg/day, GS 16 +/- 6%, TGV 41.8 +/- 8.6 mm3/kidney). In conclusion, the development of glomerular hypertrophy and GS in Milan normotensive rats was reduced by the low-protein diet, but not by low-CAP treatment.

UI MeSH Term Description Entries
D006984 Hypertrophy General increase in bulk of a part or organ due to CELL ENLARGEMENT and accumulation of FLUIDS AND SECRETIONS, not due to tumor formation, nor to an increase in the number of cells (HYPERPLASIA). Hypertrophies
D007444 Inulin A starch found in the tubers and roots of many plants. Since it is hydrolyzable to FRUCTOSE, it is classified as a fructosan. It has been used in physiologic investigation for determination of the rate of glomerular function.

D002216 Captopril A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.
