Effects of Treating Old Rats with an Aqueous Agaricus blazei Extract on Oxidative and Functional Parameters of the Brain Tissue and Brain Mitochondria

Table 6

Effects of the A. blazei extract treatment on the mitochondrial membrane energization by forward (succinate) and reverse (ATP) electron flow. The mitochondrial membrane energization (transmembrane potential) was estimated fluorimetrically using safranin as a fluorescent probe. Intact mitochondria (1 mg protein) were incubated in a medium as described in Materials and Methods. The values represent the mean ± standard errors of the mean.
