RESUMO

SUMMARY: Diabetic nephropathy (DN) is the most common complication of diabetes. Several studies have been done in a trial to protect against this problem at the ultrastructure level. This study investigates the protective effect of oral administration of Acacia senegal (AS) against the development of DN. Sixty male albino rats were randomly divided into six groups: control, Acacia senegal control, Diabetic untreated, diabetic insulin-treated, Diabetic AS treated, and Diabetic insulin and AS combined treated groups. Plasma glucose, HbA1c, serum Albumin, creatinine, urine creatinine was measured using specific kits. Determinations of creatinine clearance and blood pressure were done. The renal tissues of both kidneys were prepared to investigate under both light (LM) and electron microscope (EM). Ultrastructure examination of renal rats tissue of diabetic untreated rats showed the destruction of the glomerular basement membrane and endothelial cells together with hemorrhage in glomerular capsules (Bowman's capsules). On the other side, both LM and EM revealed improving the endothelial cells and the other glomerular capsules structures, especially with the combined treated group, which confirmed the improvement of the biochemical investigation in the study. In conclusion, from the present study, using the oral AS together with SC insulin could be protected against the development of DN.


RESUMEN: La nefropatía diabética (ND) es la complicación más común de la diabetes. Se han realizado varios estudios de ensayo para abordar esta dificultad a nivel de ultraestructura. Este estudio investiga el efecto protector de la administración oral de Acacia senegal (AS) contra el desarrollo de la ND. Se dividieron sesenta ratas albinas machos aleatoriamente en seis grupos: control, control de Acacia senegal, diabéticos no tratados, diabéticos tratados con insulina, diabéticos tratados con AS y grupos tratados con compuesto de insulina diabética + AS. Se midieron utilizando kits específicos, glucosa plasmática, HbA1c, albúmina sérica, creatinina en sangre y en orina. Se registraron la creatinina y la presión arterial. Los tejidos renales de ambos riñones se prepararon para investigar tanto con microscopio óptico (MO) como electrónico (ME). El examen de la ultraestructura del tejido renal de ratas diabéticas no tratadas mostró la destrucción de la membrana basal glomerular y las células endoteliales junto con hemorragia en las cápsulas glomerulares (cápsulas de Bowman). Por otro lado, tanto MO como ME revelaron una mejora de las células endoteliales y las estructuras capsulares glomerulares, en el grupo tratado con el compuesto, lo que confirmó la mejora de la investigación bioquímica. En conclusión, el uso de AS oral en combinación con insulina podría proteger contra el desarrollo de ND.
