Folium crataegi boosts skin regeneration for burn injury in rats through multiple ways
Appropriate topical dressings for burn treatments are important to accelerate skin wound recovery and prevent external infections. This study aimed to evaluate the effect and investigate the mechanism of folium crataegi ( Crataegus pinnatifida Bge. ) for the treatment of burn wounds, as well as to compare the therapeutic effects of aqueous extracts ( HLW ) and alcoholic extracts ( HLE ) from folium crataegi . The results demonstrated that both HLW and HLE groups exhibited a higher wound contraction rate than the silver sulfadiazine ( SSD ) ointment group. Moreover, HLW showed more significant wound repair effects than HLE . HLW significantly increased levels of EGF and FGF-2 in wound tissue, as well as TGF-β1 , VEGF , CAT and IL-10 in serum. Folium crataegi extract, especially aqueous extracts, exerted good anti-inflammatory, anti-oxidant and anti-bacterial effects by upregulating the expression of lag3 , txn1 and slpi , respectively. Folium crataegi extract significantly inhibits the expression of npas2 , a key gene in the circadian rhythm pathway. In conclusion, this research illustrated that the folium crataegi extract, especially aqueous extracts, had better therapeutic effects on skin burns through multiple ways, possibly including a novel mechanism related to circadian rhythm pathway. These findings suggest that folium crataegi could be a valuable source of compounds for enhancing skin regeneration through multiple ways.
