    Objective: In this study, we examined the effects of Polypodium vulgare L. (Polypodiaceae) as a candidate to be used for wound healing scarred area. We investigated the antibacterial, and antioxidant activity of P. Vulgare on both in vivo, and in vitro wound healing using an excisional wound model in mice Method: We used 32 Balb-c mice equally divided into four groups: Group 1 control, Group 2 vehicle, Group 3 Polypodium vulgare, and Group 4 Centella asiatica extract (CAE). All treatments were applied topically once in a day. The scar area, percentage wound closure and epithelization time were measured. PDGF, VEGF, and collagen immunohistochemical staining were used for evaluation. Results: CAE and P. vulgare extract groups were observed to be more effective than the control and vehicle groups in terms of new vascular, epidermal and granulation tissue organization. PDGF, VEGF, and collagen immunohistochemical staining was stronger in the P.vulgare extract and CAE groups compared to the control and vehicle groups. In the P. vulgare and CAE groups, PDGF staining intensity was stronger than the control and vehicle groups, but VEGF and collagen staining in P. vulgare group was not different from the control group. Conclusion: P. vulgare had an effect on the injured area by regenerating the epidermis and increasing vascularization. P. vulgare extract with known antioxidant, and antimicrobial activities may be helpful as a supportive treatment in wound healing. © Istanbul Medeniyet University Faculty of Medicine.

    In vivo wound-healing and in vitro antibacterial and antioxidant properties of Carduus adpressus extract
    (2023) Şakul, Ayşe Arzu; Ayla, Şule; Okur, Mehmet Evren; Karadağ, Ayşe Esra; Daylan, Benay; Güzel, Elif; Özdemir, Ekrem Musa; Günal, Mehmet Yalçın
    Carduus adpressus has been used for its anti-hair loss effect in traditional folk medicine. The plant species is mainly distributed in Türkiye, Bulgaria, and the Western Caucasus. The studies on this specific plant in the genus Carduus is limited which remarks the significance of the current study. This study aims to investigate the antibacterial, antioxidant, and wound-healing properties of the methanolic extract of Carduus adpressus. Extract was obtained by maceration. The broth microdilution assay was performed on Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Escherichia coli. DPPH and ABTS radical scavenging assays were performed to detect the antioxidant capacity. Wound-healing activity was tested using alloxan-induced diabetic BALB-c mice. 4 groups, control, vehicle, CAE and Carduus adpressus groups were treated with the relative agent for 10 days. Extract demonstrated 62.5 µg/mL MIC against S. aureus and E. faecalis, and 125 µg/mL MIC against P. aeruginosa and E. coli. ABTS assay showed higher antioxidant activity compared to the DPPH assay. Carduus adpressus group demonstrated strong regeneration, epithelisation, and angiogenesis compared to the control group on day 10. Additionally, expression of PDGF, VEGF, and collagen formation was increased in the Carduus adpressus group compared to the control group on day 10. Extract demonstrated strong antibacterial, antioxidant, and wound-healing activities which indicate that it could be a source in developing wound-healing agents.

    Wound Healing Activity of Arum Maculatum
    (2023) Arzu Sakul, Ayşe; Okur, Mehmet Evren; Ayla, Şule; Daylan, Benay; Karadağ, Ayşe Esra; Batur, Şebnem; Özdemir, Ekrem Musa; Altınalan, Ebrar; Günal, Mehmet Yalçın
    Objective: In this study, the antioxidant properties of Arum maculatum plant were evaluated. This study reported for the first time the wound healing activity of the methanol extract of A. maculatum fruits. This study aimed to assess and determine the possible pharmacological activities of A. maculatum and evaluate its potential to act as a wound care plant. Methods: The antioxidant and antimicrobial activities of A. maculatum were investigated using excisional in vivo and in vitro wound healing mouse models. A total of 32 Balb-c mice were used, which were equally, divided into four groups: saline control group, control group, A. maculatum group, and Centella asiatica extract group. Treatment applications were performed topically once per day. Wound area narrowing, wound healing percentage, and epithelialization time were analyzed. Results: A. maculatum application supported the healing process in in vivo and in vitro wound models. A. maculatum contributed to the healing process by promoting granulation tissue formation, epidermal regeneration, and angiogenesis. Conclusions: Wound healing is a complex and well-organized process that requires communication between cells. The antioxidant and antimicrobial activities of A. maculatum extract have been determined by current studies. A. maculatum extract may provide significant benefits in promoting the wound healing process.
