Insamhodo-tang, a traditional Korean medicine, regulates mast cell-mediated allergic inflammation in vivo and in vitro.
2011
Abstract Aim of the study Insamhodo-tang (IHT) has traditionally been used in Korea to treat a variety of diseases, including chronic cough, tuberculosis, and chronic bronchitis. However, the anti-allergic and anti-inflammatory effects of IHT and its molecular mechanisms have yet to be clearly elucidated. In this study, we attempted to evaluate the effects of IHT on mast cell-mediated allergy inflammation in vitro and in vivo . Materials and methods We investigated to ascertain the pharmacological effects of IHT on both compound 48/80-induced and 2,4-dinitrofluorobenzene (DNFB)-induced allergic reactions under in vivo conditions. Additionally, to find a possible explanation for the anti-inflammatory mechanisms of IHT, we evaluated the regulatory effects of IHT on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Results The finding of this study demonstrated that IHT reduced compound 48/80-induced systemic anaphylactic shock, DNFB-induced dermatitis, and ear swelling responses in mice. Additionally, IHT inhibited the production of interleukin (IL)-6, IL-8, and TNF-α, as well as the activation of nuclear factor-κB and caspase-1 in PMACI-stimulated HMC-1. Conclusion Collectively, the findings of this study provide us with a novel insight into the pharmacological actions of IHT as a potential molecule for use in the treatment of allergic inflammation diseases.
