Fig. 1From: Anti-inflammatory activities of Guang-Pheretima extract in lipopolysaccharide-stimulated RAW 264.7 murine macrophagesThe effect of GPD and PF-GPD on RAW264.7 cells viability was investigated by MTT assay at various concentrations (5–320 μg/mL) in the absence (a and c) or presence (b and d) of 1 μg/mL of LPS. Data was analyzed and expressed as mean ± SEM. Statistical significance of the differences were performed by one-way ANOVA for multiple comparisons followed by the LSD test for comparisons between groups. *P < 0.05, **P < 0.01 compared with the untreated groupBack to article page
