ABSTRACT
Aim To investigate the effect of flavonoids from Prinsepia utilis Royle( FPR) on the histomorphol-ogy of kidney in diabetic mice, and to investigate its protective mechanism. Methods Diabetic mice in-duced by alloxan were given FPR orally each day for four weeks. After the administration for two and four weeks, ten mice in each group were randomly sacri-ficed. The kidneys were removed and weighed. The extracted renal tissue was embedded with paraffin and sectioned, the sections were stained with Hematoxylin and Eosin(HE)、Periodic acid Schiff(PAS) and Go-mori, and then observed under the microscopy. 1mm3 of renal cortex fixed with glutaral in four centi-degree , and then the ultrastructure of each group was observed under the electron microscope respectively after four weeks′ treatment. Results Compared with the model control group, in the treatment group, observation un-der the microscopy showed that glomerular volume and mesangial cells reduced, FPR could relieve thickening of the glomerular basement membrane ( GBM ) , little inflammatory cells infiltrated in the interstitium,tubular epithelial cells almost became normal, renal tubule had little glucogen, fiber decreased in the interstitium of renal tubule. Observation under the electron micro-scope indicated that foot process in podocytes lined up in order, mitochondria of the renal tubule’ s epithelial cell almost recovered. Conclusion FPR can relieve the changes of renal pathology,improve renal function, and delay the progression of pathologic changes of kid-ney in diabetic mice partly through reducing the blood glucose and the blood lipid.
