Figure 2From: An investigation into the ameliorating effect of black soybean extract on learning and memory impairment with assessment of neuroprotective effects Cytoprotective effect of the NAF from black soybean seed coat on Aβ-induced neurotoxicity in PC12 cells. (A) Protective effect of the NAF on Aβ-induced cytotoxicity in PC12 cell system. PC12 cells were pretreated for 48 h with various concentrations. After 48 h, the cells were treated with 25 μM Aβ for 3 h. (B) Inhibition of lactate dehydrogenase release of the NAF on Aβ-induced membrane injury in PC12 cell. Bars were represented with the mean ± SD (n = 3). Significant difference (p < 0.05 versus vitamin C) was observed on the Aβ-induced cell death. Different superscripts indicate significant difference among groups at p < 0.05.Back to article page
