Fig. 3From: Anti-inflammatory activities of astringent persimmons (Diospyros kaki Thunb.) stalks of various cultivar types based on the stages of maturity in the Gyeongnam provinceEffects of various stalk extracts on cell viability in RAW 264.7 macrophages cells. Cells were treated with concentrations (0, 10, 50, 100, 200, 500, 1000 μg/ml) of various stalk extract for 24 h. Cell viability was measured using the CCK-8 assay. The results are presented as the mean ± SD of at least three independent experiments. *P < 0.05, **P < 0.01, *** P < 0.001, **** P < 0.0001Back to article page
