ABSTRACT Angelicae Gigantis (AG) Radix, commonly used medicinal food, has been reported as a promising candidate for inflammatory diseases. However, the anti-allergic effects of AG and its molecular mechanisms have yet to be clarified. The present study investigated the anti-allergy effects of ethanol extracts of AG on mast cell-mediated allergic inflammation in vivo and in vitro. The finding of this study demonstrated that AG reduced anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis, compound 48/80-induced histamine release, 2,4-dinitrofluoro benzene-induced contact hypersensitivity. In addition, AG inhibited the production of interleukin (IL)-6, IL-8, and TNF-α, as well as the activation of Jun N-terminal kinase and nuclear factor-κB in phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated human mast cells. In conclusion, our results provide a novel insight into the pharmacological actions of AG as a potential candidate for use in allergic inflammatory diseases.

    ABSTRACT: Soyo-san is a traditional oriental medicinal formula, a mixture of 9 crude drugs, and it has been clinically used for treating mild depressive disorders. The role of pro- and anti-inflammatory cytokines in psychiatric disorders has been the focus of great research attention in recent years. In the present study, we detected the antidepressant effect of soyo-san in the ovariectomized and repeated stressed female rats. This study was designed to evaluate the antidepressant-like effect of soyo-san on the forced swimming test (FST). The rats were randomly divided into the following groups: the nonoperated and nonstressed group (non-op), the nonoperated and stressed group (non-op + ST), the ovariectomized and stress group (OVX) and sham operated and stressed group (sham), the ovariectomized and stressed group (OVX + ST), the ovariectomized, stressed and soyo-san 100 mg/kg treated group (SOY100) and the ovariectomized, stressed and soyo-san 400 mg/kg treated group (SOY400). The rats were exposed to immobilization stress (IMO) for 14day (2 h/14day), and soyo-san (100 mg/kg and 400 mg/kg) was administrated during the same time. In the same animals, the levels of corticosterone and interleukin-1-beta (IL-1beta) were examined in the serum. Also, the change of IL-1beta expression in brain regions was examined after behavior test. In the FST, the lower dose (100 mg/kg) of extract was effective in reducing immobility, along with an increase in swimming time. The serum levels of corticosterone and IL-1beta in the SOY groups were significantly lower than that in the control group. In the brain, the expression of IL-1beta positive neurons in the control group significantly increased in the paraventricular nucleus (PVN) and hippocampus compared to the non-op. However, soyo-san groups significantly reduced the IL-1beta-ir neurons in the PVN and hippocampal regions compared to the control. The present results demonstrated that soyo-san effectively reduced behavioral and patho-physiological depression-like responses. Trial registration: Our results suggest that soyo-san may be useful for an immune promoter in repeated stress-induced ovariectomized female rats.
