Publication Open Access Ethanol extract of Cotinus coggygria leaves accelerates wound healing process in diabetic rats(TAYLOR & FRANCIS LTD, 2016-11) ŞEN, ALİ; Aksoy, Halil; Sen, Ali; Sancar, Mesut; Sekerler, Turgut; Akakin, Dilek; Bitis, Leyla; Uras, Fikriye; Kultur, Sukran; Izzettin, Fikret VehbiContext:Cotinus coggygria Scop. (Anacardiaceae) leaves that were used as wound healing in traditional Balkan and Anatolian folk medicine, could be potentially effective in treating diabetic wounds.Objective: This study investigates biochemical and histological effects of ethanol extract of C. coggygria (CCE) on excision wound model in diabetic rats.Materials and methods: This study was conducted on diabetic Wistar albino rats, which were injected by a single dose (50mg/kg i.p.) streptozotocin. Afterward an excision wound model was created in all animals; diabetic control rats were applied topically simple ointment and diabetic treatment rats were applied topically 5% (w/w) ointment with CC, once a day during the experimental period. Malondialdehyde, glutathione and hydroxyproline levels in wound tissues were investigated at the end of 3rd, 7th, and 14th days. Histopathological examination was also performed.Results: Hydroxyproline content was significantly increased in the CCE treated group versus control after the 3rd and 7th days (15.33 versus 11.83; 19.67 versus 15.67mg/g, p<0.05; respectively). A statistically significant elevation in glutathione at the end of 3rd, 7th, and 14th days (5.13 versus 1.58, p<0.05; 4.72 versus 1.88, p<0.05; 3.83 versus 1.88mol/g, p<0.05, respectively) and a statistically significant decrease in malondialdehyde level at the end of 7th day (4.49 versus 1.48nmol/g, p<0.05) were determined in the treated group versus control group. These results were also supported by histological analyses.Discussion and conclusion: These findings indicate that CCE accelerated the cutaneous wound healing process in diabetic wounds, in confirmation of its traditional use.Publication Metadata only 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, AzizeThe 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.Publication Metadata only 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 VehbiThe 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.Publication Open Access Yara İyileşmesi ve Oksidatif Stress(2014-09-08) AKSOY, HALİLPublication Metadata only The biochemical assessment of the effectsof Nigella sativa oil on cutaneous wound healing in rats(2010-06-09) RABUŞ, ŞULE; SANCAR, MESUT; OKUYAN, BETÜL; AKSOY, HALİL; AKSOY H.
