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 2

Effect of Drynaria rhizome extract (DRE) at concentrations of 100, 300, and 500 μg/mL on the release of β-hexosaminidase and proinflammatory cytokines from RBL-2H3 mast cells. (a) β-Hexosaminidase. (b) TNF-α. (c) IL-4. (d) IL-6. The results are expressed as the means ± SE of at least three independent experimental results that were tested by analysis of variance with Bonferroni’s post hoc testing. #, the control group versus the DNP-HSA group; , the DNP-HSA group versus the DRE and Dex treatment group. NS, not significant at the 0.05 probability level.
