    Ankaferd Blood Stopper with antibiofilm potential successfully inhibits the extracellular matrix degradation enzymes and promotes wound healing of 3T3 fibroblasts in vitro
    (Tubitak Scientific & Technical Research Council Turkey, 2018) Boran, Rukiye; Baygar, Tuba; Saraç, Nurdan; Uğur, Aysel
    Background/aim: The potential inhibitory effects of Ankaferd Blood Stopper (ABS) against biofilm formation of oral microorganisms and its capacity for collagenase, hyaluronidase, and elastase inhibitions that have important roles in wound healing have been investigated. Materials and methods: The wound healing potential was determined by its inhibition ability on collagenase, hyaluronidase, and elastase enzyme activities and was evaluated via scratch wound healing assay on murine 3T3 fibroblasts. The antibiofilm activity was tested against eight oral microorganisms using the crystal violet staining method. Results: At 10% ABS successfully inhibited the biofilm formation of the tested microorganisms. Enzyme inhibition analysis revealed that 3% ABS significantly inhibited all three enzymes related to wound healing. The scratch assay showed that wound closure was faster than that of the control for the 3% ABS/plate. Conclusion: The findings of the present study indicated that ABS has effective wound healing potential with its strong antibiofilm activity against oral cavity microorganisms.

    Antimicrobial, antifibrinolytic, enzyme inhibitory and wound healing properties of zinc borate
    (TENMAK Bor Araştırma Enstitüsü, 2023) Boran, Rukiye; Baygar, Tuba; Saraç, Nurdan; Ayrıkçıl, Semih; Yılmaz, Derviş; Uğur, Aysel
    Boron containing compounds (BCGs) have recently been used for pharmaceutical applications. Zinc, an essential element, is known to be one of the most promising biodegradable metals. The present study was conducted to determine the wound healing properties of zinc borate with its antimicrobial, antifibrinolytic and enzyme inhibitory characteristics. In vitro scratch wound healing assay revealed that zinc borate at 0.01 µg/mL concentration stimulated the proliferation of 3T3 fibroblast cells after 24 h of scar formation. The highest enzyme inhibition was observed against collagenase at 1 mg/mL (81.5%). Minimum inhibition concentration (MIC) values were determined as 1 mg/mL and 0.5 mg/mL against Candida albicans and Staphylococcus aureus, respectively. Zinc borate did not have any fibrinolytic activity at 1, 0.5 and 0.1 mg/mL concentrations. It can be suggested that zinc borate can be used effectively to improve the wound healing process and to prevent the possible wound infections.

    In vitro biological activities of potassium metaborate; antioxidative, antimicrobial and antibiofilm properties
    (TENMAK Bor Araştırma Enstitüsü, 2022) Baygar, Tuba; Saraç, Nurdan; Ceylan, Özgür; Uğur, Aysel; Boran, Rukiye; Balcı, Uydu
    Antioxidant, antimicrobial and antibiofilm activities of potassium metaborate (KBO2) was investigated within the present study. Antioxidant capacity of potassium metaborate was determined by ?-carotene bleaching (BCB) assay and hydroxyl radical scavenging activity. Potassium metaborate was evaluated for its antimicrobial effects against selected Gram-positive bacteria, Gram-negative bacteria and a yeast via broth dilution method. The inhibition capability of potassium metaborate on the microbial biofilm formation of tested microorganisms was measured by microplate biofilm method using MTT (3- [4, 5- dimethyl-2-thiazolyl]-2, 5-diphenyl-2H-tetrazolium-bromide). Biofilm inhibition capacity of potassium metaborate was also observed by Scanning Electron Microscope (SEM). Potassium metaborate was found to have the ability to scavenge hydroxyl radicals with an inhibition rate of 71.13% at 100 mM concentration. Antioxidant activity of potassium metaborate as determined by BCB assay gave higher result with an inhibition rate of 86.96% at the same concentration. According to the MIC (minimum inhibition concentration) values, the potassium metaborate inhibited the growth of C. albicans, S. aureus and E. coli at 62.5 mM concentrations while it was 31.25 mM for B. subtilis and 125 mM for P. aeruginosa. The highest antibiofilm activity was determined at the MIC of potassium metaborate with the reduction rate of 90.18% against C. albicans. It was concluded that, potassium metaborate have strong biological activities and can be effectively used for biomedical and environmental solutions.
