Abstract

Hataedock (HTD) treatment is a traditional preventive therapy for the fetal toxicosis- the acute allergic disease after childbirth, mainly manifested by a variety of skin allergies such as scab, phlegm. The aim of this study was to investigate the efficacy of HTD treatments for the alleviation of inflammation in Dermatophagoides farinae-induced obese NC/Nga mice. 20 mg/kg of Coptidis Rhizoma, Glycyrrhizae Radix (CRGR) extracts as a remedy of HTD treatments were orally administered to NC/Nga mice. We induced obesity in the mice by high-fat diet. To induce skin allergies, the extracts of Dermatophagoides farinae were topically applied on the NC/Nga mice at 4th-6th and 8th-10th weeks. Structural and molecular changes in the skin tissues were measured by immunohistochemical staining. HTD treatment decreased the atopic dermatitis (AD)-like symptoms including hemorrhage, erythema, erosion, edema, and dryness. HTD treatment suppressed the mast cell activation confirmed by reduction of Fc?RI, substance P, and serotonin. The expression of several inflammatory mediators including nuclear factor-kappa B (NF-κB) p65, inducible nitric oxide synthase (iNOS), vascular endothelial growth factors (VEGFs) was also decreased by HTD treatment. HTD treatment suppressed the allergic, inflammatory responses in the skin tissues of the NC/Nga mice by reducing mast cells and down-regulating several inflammatory mediators.
