Effect of herbicides in the oxidative stress in crop winter species.

abstract：:Experiments in this paper demonstrate that mitochondrial damage associated to NAD(P)+-induced Ca2+ efflux, is the consequence of inappropriate reaction conditions. The major findings are (i) Added oxaloacetate and acetoacetate readily oxidize NAD(P)H in intact rat liver mitochondria without causing swelling or membran...
