Effect of Angelicae Dahuricae Radix (AR) on plasma levels of histamine and IgE in Dermatophagoides farinae-induced AD-like lesions in NC/Nga mice. The groups were untreated (cont), D. farinae plus vehicle-treated (D. farinae), D. farinae plus tacrolimus-treated (tacrolimus), and D. farinae plus AR-treated (AR) NC/Nga mice. The plasma concentrations of histamine (a) and IgE (b) were measured by ELISA (mean ± SEM, ), #: , ##: compared with control group, *: , **: compared with D. farinae-induced group.
