Figure 2From: Ameliorating effects of aged garlic extracts against Aβ-induced neurotoxicity and cognitive impairment Effect of ethyl acetate fraction from aged garlic extract on ROS production determined in the presence and absence of Aβ in PC12 cell. PC12 cells were pretreated for 48 h with various concentrations. After 48 h, the cells were treated with 80 μM Aβ for 2 h. The increase of DCF-DA fluorescence was measured by fluorescence microplate reader. Each value represented the means ± SD of triplicates. Different superscripts indicate significant difference among groups at p < 0.05.Back to article page
