Para Determinar

Glutathione (GSH) provides an important antioxidant and detoxification pathway. We tested to determine if direct administration of GSH or GSH ester could reduce cisplatin- (CDDP) induced ototoxicity. We tested eight groups of five rats each: a control group, a group receiving 16 mg/kg ip CDDP infused over 30 minutes, and six groups receiving either GSH or GSH ester at 500, 1000, or 1500 mg/kg intraperitoneally 30 minutes prior to 16 mg/kg CDDP. Auditory brainstem response thresholds were measured for click and tone-burst stimuli at baseline and 3 days later. Outer hair cell (OHC) loss was measured for the apical, middle and basal turns. The 500 mg/kg GSH ester reduced hearing loss and OHC loss, but protection decreased as dosage increased, suggesting possible toxicity. GSH was not significantly protective. The best GSH ester protection was less than we have previously reported with D-methionine. El glutatión (GSH) brinda una importante vía antioxidante y de cetoxificación. Realizamos una prueba para determinar si la administración directa de GSH o del éster de GSH podía reducir la ototoxicidad inducida por cisplatino (CDDP). Hicimos una evaluación en ocho grupos de cinco ratas cada uno: un grupo control, un grupo que recibió CDDP intraperitoneal a 16 mg/kg en una ínfusión durante 30 minutos y seis grupos que recibieron intraperitonealmente GSH o el éster de GSH a 500, 1000 o 1500 mg/kg, 30 minutos antes del CDDP a 16 mg/kg. Se midieron umbrales de respuestas auditivas del tallo cerebral tanto para clicks como para bursts tonales, al inicio y 3 días después. La pérdida de células ciliadas externas (OHC) fue establecida a nivel de las vueltas apical, media y basal. La dosis de 500 mg/kg de éster de GSH redujo la hipoacusia y la pérdida de OHC, pero la protección disminuyó conforme la dosis se incrementó, sugiriendo una posible toxicidad. EL GSH no resultó significativamente protector. El mejor efecto protector del éster de GSH fue menor que el previamente reportado con D-Metionina.
