RESUMO
La respuesta natriurtica y la hemodin mica glomerular dependen de diversos sistemas de regulaci¢n intrarrenal; sin embargo, la mayor¡a de ellos posee alg£n grado de dependecia del sistema renina angiotensina. La distribuci¢n tisular y el efecto hemodin mico de este sistema son de vital importancia para el entendimiento de la regulaci¢n natriurtica y del filtrado glomerular en diversas enfermedades que se caracterizan por desregulaci¢n del equilibrio del sodio o del filtrado glomerular, tales como el s¡ndrome nefr¢tico, la falla renal aguda y cr¢nica e hipertensi¢n arterial.
Natriuretic response and glomerular hemodynamics depend on various intrarenal regulation systems; however, most of them possess some degree of dependence on the renin-angiotensin system. Tissue distribution and hemodynamic effects of this system are of vital importance for understandinf of the natriuretic and glomerular filtration regulation in the context of different diseases characterized by dysregulation of sodium balance or glomerular filtration rate, such as nephrotic syndrome, acute and chronic renal failure and hypertension.
