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 Evaluation of biochemical parameters inRubus tereticaulistreated rats and its implications in wound healing(SPRINGER, 2020) ŞEN, ALİ; Aksoy, Halil; Demirbag, Caglar; Sen, Ali; Sekerler, Turgut; Ozakpinar, Ozlem; Sener, Azize; Ahmad, Sarfraz; Tetik, SerminWe evaluated the effects ofRubus tereticaulisin healing process by determining the total carbonyl content, collagen synthesis, and total protein level on rat wounded tissues. Wounds were performed in the back of 54 Wistar rats, using a biopsy punch instrument with 0.6 mm in diameter. Rats were randomly divided into three groups: (i) un-treatment wounds group served as controls, (ii) Madecassol (R) used as positive control group, and (iii) the application of topical cream ofR. tereticaulisserved as treatment group of wound healing. The animals were killed at the end of experiment under anesthesia with ketamine, and tissue samples were collected for the evaluation at three times intervals (3rd, 7th, and 14th day). The wounded areas were analyzed for total carbonyl content, collagen, and total protein levels by HPLC, ELISA, and spectrophotometric methods, respectively. Total carbonyl content in the treatment group was significantly lower in comparison with control group on 3rd day (2.839 +/- 0.438 vs. 3.216 +/- 0.216 nmol carbonyl/mol protein;p < 0.5) and 14th days (4.222 +/- 0.128 vs. 4.784 +/- 0.077 nmol carbonyl/mol protein;p < 0.05), respectively. New collagen formation on the wound sites after the initial injury was noted in the treated and positive control groups (5.310 +/- 0.331 vs. 5.164 +/- 0.377 mg collagen/g wet tissue) at the 3rd day than control group (2.180 +/- 0.718 mg collagen/g wet tissue,p < 0.01), and in treated and positive control groups at 7th day (9.654 +/- 0.201, 9.053 +/- 1.062 mg collagen/g wet tissue,p < 0.01); and in treated and positive control groups at 14th day (8.469 +/- 0.236, 5.631 +/- 0.531 mg collagen/g wet tissue, respectively;p < 0.05) in comparison with the control group. Total protein level of samples did not change significantly between the groups. Thus, application ofR. tereticaulisameliorated the wound healing process in rats as it facilitated collagen formation through healing of the wound. Evaluating total carbonyl content by HPLC could be useful as an advance procedure for quantification of healing.Publication Open Access The Effect of Algan Hemostatic Agent (AHA) on Wound Healing(MARMARA UNIV, INST HEALTH SCIENCES, 2020-09-04) ŞEN, ALİ; Aksoy, Halil; Sener, Azize; Akakin, Dilek; Sen, Ali; Ozakpinar, Ozlem Bingol; Ozcan, Sinemcan; Simsek, Ahmet Kaan; Sekerler, Turgut; Guzel, Sevket Ergun; Midi, AhmetObjective: The Algan Hemostatic Agent (AHA) is a novel herbal originated blood stopper. The aim of this study is to investigate the effect of AHA on wound healing on excisional wound model in rats. Methods: In this study, 54 adult Wistar albino rats were used. Rats were divided into 3 groups (saline, Madecassol (R) and AHA). Each group was then divided into 3 subgroups as the 3rd, 7th and 14th days. Two wounds were created in the dorsal thoracic region of the rats. One of the lesions was used for histopathological examinations and the other for hydroxyproline measurement. In order to evaluate the wound healing, wound area were measured during the whole treatment period and animals were sacrificed at the end of the 3rd, 7th and 14th days and tissue samples were taken for the determination of hydroxyproline levels. Results: AHA treatment did not cause significant difference in hydroxyproline level on days 3, 7, 14. The contraction percentage of wound area was higher in the AHA group on day 7 than that of the control group. However, the difference was not statistically significant (p>0.05). On days 3 and 14, no significant difference was detected in the contraction percentage of wound area between the control and the AHA groups. AHA and Madecassol (R) results of epidermis regeneration on the 14th day, neutrophil infiltration on the 7th day and edema on the 3rd, 7th and 14th days were different in terms of histopathological parameters compared to the control group. Conclusion: Despite good histological findings, AHA did not significantly accelerate wound healing, but did not adversely affect wound healing as well.Publication Open Access In silico investigation of wound healing potential of some compounds in tubers of Asphodelus species with GSK3-beta protein(MARMARA UNIV, 2021) AKSOY, HALİL; Aksoy, Halil; Sekerler, Turgut; Mert, Naz MinaWound healing is a process that involves biochemical processes such as inflammation and cell proliferation and is controlled by many proteins. It is known that one of the most effective factors in this process is the inhibition of GSK3-beta protein. In current study, in silico wound healing activity of the some compounds found in the tubers of Asphodelus species used as a wound healing in traditional medicine were investigated. For this purpose, the interactions between the compounds and GSK3-beta protein were studied in silico. As a result of the study, it has been determined that and stigmasterol, beta-sitosterol and emodin molecules are effective.
