Abstract

|
Objectives: Objective: The purpose of this study was to confirm effect of reducing inflammation of Coptis chinensis extract -ceramide complex through the endocannabinoid system (ECS) control in atopic dermatitis.
Methods: 8-week-old ICR mice were divided into normal group (Ctrl), lipid barrier elimination group (ADE), palmitoylethanolamide treated group after lipid barrier elimination (PEAT), and Coptis chinensis extract-ceramide complex applied group after lipid barrier elimination (CRA). After inducing atopic dermatitis, cannabinoid receptor (CB) 1, CB2, CD68, p-IκB, iNOS, substance P and serotonin were observed to confirm the regulation of the ECS, macrophage activity and mast cell activity.
Results: CB1 and CB2 showed higher positive reactions in the CRA than in the ADE and PEAT. CD68, p-IκB and iNOS showed higher positive reaction in the ADE, PEAT and CRA than in the Ctrl, but the increase in the positive reaction was lower in the CEA compared to the ADE and PEAT. Substance P and serotonin showed higher positive reaction in the ADE, PEAT and CRA than in the Ctrl, but the increase in the positive reaction was lower in the CEA compared to the ADE and PEAT.
Conclusions: The effects of Coptis chinensis extract -ceramide complex were confirmed on the regulation of the ECS, macrophage activity and mast cell activity.
