Fig. 1From: Antiangiogenic effects of oridoninEffect of oridonin on HUVEC viability. HUVECs were treated with various concentrations (20–2500 μg/ml) of oridonin, and viability was determined by MTT assay at 24, 48, 72, and 96 h. a HUVEC viability at 24 h; b HUVEC viability at 48 h; c HUVEC viability at 72 h; d HUVEC viability at 96 hBack to article page
