The effects of aqueous-ethanol extract of Horse chestnut (HCE) on MMP-1 and MMP-9 expressions during cutaneous wound healing in diabetic rats were investigated in this study. The expressions of MMP-1 and MMP-9, wound closure, myeloperoxidase (MPO) activity, hydroxyproline, and malondialdehyde (MDA) levels in wound tissue were measured. Quercetin glucuronide in HCE was identified as main compound using a LC-MS/MS. The hydroxyproline level was significantly increased in the treated group versus control after the 3rd and 7th days (p < 0.05). The MDA level and MPO activity were significantly lower in the treatment group (p < 0.05). MMP-1 gene expression level in treated rats was increased in the 7th day while it was reduced in 14th day. MMP-9 gene expression level in treated rats was decreased in 7th, and 14th days compared to control (p < 0.05). These results show that HCE accelerated the cutaneous wound-healing process in diabetic rats via MMP-1 and MMP-9 regulation. PRACTICAL APPLICATIONS: The main function of MMPs is to degrade and deposite the various components of the extracellular matrix. Also, they participate physiologicalprocesses such as inflammation, angiogenesis, and tissue remodeling. Horse chestnut seeds (HC) are known to be rich in saponins and flavonoids. HC are used for the treatment of abdominal pain, stomach ache, cold, hemorrhoids, arterial stiffness, rheumatism, oedema, diarrhea, chronic venous insufficiency and also as an antihemorrhagic and antipyretic in traditional medicine. It has been shown that HC has anti-inflammatory, antioedema, vessel protective, and free radical scavenging properties. This study indicates that HCE could be an effective agent for wound healing in diabetic wound model viaits ability to suppress the MMP-9 gene expression and regulates MMP-1 gene expression besides its antioxidative, anti-inflammatory effects.
