ABSTRACT
Due to its prominent role in major excretory pathways, the kidney is particularly sensitive especially to toxicity for antimicrobials drugs. Storage of these drugs in the renal cortex, their effect on renal cells, have consequences on the renal function, and then reabsorbed by renal tubules induce nephrotixicity. Our objective was to show the renal morphopatological alterations induced by gentamicin through the histochemical methods of routine periodic acid de Schiff (PAS) staining and imunohistochemical staining for the expression of the protein P53, which is considered as a marker for cellular apoptosis. This allows the early detection of tubular lesions. The renal morphopathologic findings were cell apoptosis, basal membrane interruption, mesangial proliferation cells, decreased Bowman's space. This result clearly shows that gentamicin administration induces renal morphopatological alterations.
RESUMEN
Debido a su importante rol en la función de excreción mayor, el riñon es especialmente propenso a la toxicidad por los antibióticos bactericidas. La acumulación de los antibióticos aminoglicosidos en la corteza renal tiene como consecuencia efectos en las células renales y en la función renal y cuando son reabsorbidos por los túbulos renales, pueden conducir a toxicidad renal. Nuestro objetivo fue mostrar alteraciones morfopatológicas renales causadas por la administración de gentamicina, a través de métodos histoquímicos de rutina con ácido periódico de Schiff (PAS) y tinción inmunohistoquímica para la expresión de la proteína P53, la cual es considerada como un marcador para la apoptosis celular, permitiendo la detección precoz de lesiones tubulares. Los resultados morfopatológicos renales fueron apoptosis celular, interrupción de la membrana basal, proliferación de células mesangiales y disminución del espacio de Bowman. Los resultados mostraron claramente que la administración de gentamicina induce alteraciones morfopatológicas renales.
