| Outline of Final Research Achievements |
In this study, we attempted to clarify effects of rice endosperm protein (RBP) and rice bran protein (RBP) on chronic kidney disease-mineral and bone disorder (CKD-MBD) in type 2 diabetic model rats. Male ZDF rats rats were employed and fed a REP and RBP diet for 10 weeks. Hemoglobin A1c, a marker for diabetes, and urinary albumin excretion, a diagnostic criterion of diabetic nephropathy, were significantly suppressed by consuming REP and RBP compared with casein (C). These results strongly suggest that REP and RBP ameliorated diabetes and diabetic nephropathy. Fibroblast growth factor 23, one of the regulating factors for phosphate in blood, in the REP and RBP groups significantly suppressed compared with the C group. In addition, femoral microstructures and bone strength deteriorated in ZDF rats compared with non-diabetic rats but the deterioration was suppressed by REP and RBP consumptions. Therefore, it is indicated that REP and RBP had suppressive effects on CKD-MBD in ZDF rats.
