Fig. 2From: Danggui Buxue Tang, an ancient Chinese herbal decoction, protects β-amyloid-induced cell death in cultured cortical neuronsNeuroprotective functions of DBT against Aβ-induced cell death. a Cultured cortical neurons were treated with Aβ at different concentration for 48 h. b DBT extract (0–100 μg/mL) was applied 3 h before Aβ (20 μM) for another 48 h. c Crystal violet was employed for revealing cell viability after drug treatment for 48 h. Live cells were dyed and shown in purple color. In (c) and (d), Aβ (20 μM), DBT-L (12.5 μg/mL), DBT-H (100 μg/mL) were used here, and the treatment was similar as in (b). Values were expressed as the percentage of decrease or control reading in Mean ± SEM, where n = 3. Bar = 100 μmBack to article page
