- Abstract
- Objectives The aim of this study was to identify the effect of Baekho-tang extract on epidermal barrier recovery and inflammation relief in atopic dermatitis-induced mice through Endocanabinoid system (ECS) regulation.
Methods In this study, we used 4-week-old NC/Nga mice were divided into 4 group: lipid barrier elimination group (LBEG), palmitoylethanolamide treated group after lipid barrier elimination (PEAT), Baekho-tang extract treatment group after lipid barrier elimination (BHTT) and control group (Ctrl). Each group was assigned 10 animals. We identified that cannabinoid receptor (CB) 1, CB2, CD (Cluster of Differentiation) 68, inducible nitric oxide synthase (iNOS), substance P and Matrix metallopeptidase 9 (MMP-9) through our immunohistochemistry.
Results We discovered that when compared to PEAT, 8-hydroxydeoxyguanosine, a marker of oxidative stress in the epidermal barrier, and CB1 and CB2, markers of ECS modulation, were less activated in BHTT. These results led to an anti-inflammatory response in BHTT, with a significant decrease in several inflammatory mediators such as CD 68, iNOS, substance P and MMP-9 compared to PEAT and LBEG.
Conclusions These results suggest that the Baekho-tang extract can reduce the inflammation of atopic dermatitis by restoring the structural damage of the skin lipid barrier through ECS modulation.
