Davallia mariesii Moore Improves FcεRI-Mediated Allergic Responses in the Rat Basophilic Leukemia Mast Cell Line RBL-2H3 and Passive Cutaneous Anaphylaxis in Mice

Figure 1

Effects of Drynaria rhizome extract (DRE) on cell viability in RBL-2H3 mast cells. RBL-2H3 mast cell viability was analyzed using an MTT assay after treating the cells with DRE (at 100, 300, and 500 μg/mL) for 1 h and then treating them with DNP-HSA (0.1 μg/mL) for 4 h. The results are expressed as means ± SE calculated from at least three independent experimental results that were tested by analysis of variance with Bonferroni’s post hoc testing. NS, not significant at the 0.05 probability level.
