RESUMEN
ABSTRACT PURPOSE: To evaluate the effect of the aqueous extract of the Vigna angularis, popularly known as "Azuki beans", in rats subjected to an experimental model of moderate chronic kidney disease. METHODS: Thirty rats underwent two surgeries - Ormrod and Miller (1980) - to obtain Moderate Chronic Kidney Disease (CKD-M). The animals were randomized into 3 groups. Group 1 (Control): distilled water. Group 2 (Azuki): Vigna angularis 5% aqueous extract. Group 3 (Treatment): 10mg/kg of enalapril maleate. The rats received their respective treatments for 14 days. RESULTS: The treatment with azuki beans produced an increase in urine output from the second day until the end of the experiment compared to the Control groups (p<0.01) and Treatment (p<0.05). The treatment with azuki also produced significant reductions in the levels of glucose, triglycerides, VLDL, uric acid, Alanine aminotransferase (p<0.05), urea and serum creatinine (p<0.01), besides having produced a significant increase in the levels of HDL when compared to the Control group. CONCLUSION: Treatment with Azuki beans produced improvements in the parameters of renal function and significantly reduced glucose levels, triglycerides, VLDL, alanine aminostransferase, uric acid and creatinine, besides having produced a significant increase in the levels of HDL in rats submitted to a model of moderate chronic kidney disease.
