    Effect of Horse-chestnut seed extract on matrix metalloproteinase-1 and-9 during diabetic wound healing
    (WILEY, 2019) ŞEN, ALİ; Aksoy, Halil; Cevik, Ozge; Sen, Ali; Goger, Fatih; Sekerler, Turgut; Sener, Azize
    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.

    The effect of topical ethanol extract of Cotinus coggygria Scop. on cutaneous wound healing in rats
    (TAYLOR & FRANCIS LTD, 2016) ŞEN, ALİ; Aksoy, Halil; Sancar, Mesut; Sen, Ali; Okuyan, Betul; Bitis, Leyla; Uras, Fikriye; Akakin, Dilek; Cevik, Ozge; Kultur, Sukran; Izzettin, Fikret Vehbi
    The aim of this study is to determine the cutaneous wound healing effects of the ethanol extract of Cotinus coggygria leaves in rats by excision wound model to provide scientific evidence for the traditional use of C. coggygria Scop. The levels of malondialdehyde, catalase, superoxide dismutase, glutathione and hydroxyproline were investigated in wound tissues. Histopathological examination was also performed. The hydroxyproline content of the granulation tissue and the glutathione levels were both significantly higher in the treatment group than in the control group (p < 0.05 for both); while the malondialdehyde levels were significantly lower in the treatment group (p < 0.05). These results were supported with histological results. The ethanol extract of C. coggygria Scop could be considered as an effective agent in wound healing in accordance with its traditional use.
