Effects of rivastigmine, selegiline, and rivastigmine + selegiline on brain antioxidant status (TAS). TAS values were determined in each homogenized rat whole brain. Values of the groups of aged control rats and of rivastigmine indicate the mean ± standard error (SE) of ten independent experiments (ten rats). Values of the groups of adult control rats, of selegiline, and of rivastigmine + selegiline indicate the mean ± SE. of eleven independent experiments (eleven rats). The average value of each experiment arises from three determinations.

Notes: NS, nonstatistical significance; ***P < 0.001 compared with aged control group; ###P < 0.001 compared with selegiline-treated group.
