Resumen Introducción: La ototoxicidad por cisplatino es un evento muy frecuente y sus consecuencias producen mucho deterioro en los pacientes. El diagnóstico precoz es esencial, pues permitiría implementar apropiadamente estrategias para aminorar su efecto. Entre estas tenemos la N-acetilcisteína, un...

Renoprotective effect of N-acetylcysteine depends upon the severity of the ischemia reperfusion injury

Braz. j. med. biol. res; 54 (11), 2021
Acute kidney injury (AKI) is a common complication in seriously ill patients, while renal ischemia-reperfusion (I/R) injury is the most frequent event in this oxidative renal injury. N-acetylcysteine (NAC) is a small molecule containing a thiol group that has antioxidant properties, promoting detoxificat...
