ÖZAmaç: Bu çalışma, sıçanlarda oluşturulan deneysel yara modelinde Pistacia atlantica yağı ile hazırlanmış jel formülasyonunun, enzimatik antioksidanlar üzerindeki etkisini araştırmak amacıyla yapılmıştır. Gereç ve Yöntemler: Genel anestezi altına alınan hayvanlarda, aseptik koşullarda, insizyon yapmak suretiyle kare şeklinde yaralar (2x2 cm) oluşturulmuştur. Daha sonra, hayvanlar rasgele dört gruba ayrılmıştır (I-tedavi edilmemiş kontrol grubu, II-haricen uygulanan baz jel grubu, IIIharicen %5 jel uygulanan grup, IV-haricen %10 jel uygulanan grup). Bulgular: Sonuçlar, Pistacia atlantica yağı ile hazırlanmış jel formülasyonunun haricen uygulanmasının, kontrol ve baz jel gruplarına kıyasla, bütünlüğü bozulmamış stratum bazalisi, olgun granülasyon dokusunu, kıl folikülleri ve ter bezleri ile reepitelizasyonu arttırdığını göstermektedir. Yara oluşumundan 21 gün sonra, %10 yağlı jel ile tedavi edilen hayvanların dokularındaki gerilme kuvveti, kopma gerilimi ve bükülme direnci, kontrol ve baz jel grubu ile karşılaştırıldığında önemli ölçüde artmıştır. Aynı evredeki kontrol ve baz jel ile muamele edilen gruplara kıyasla, kollajen liflerin daha organize bir düzenlenme ve dokunun daha düzgün bir iyileşme gösterdiği belirlenmiştir. Sonuç: Pistacia atlantica yağ jelinin haricen uygulanmasının, sıçanlarda oluşturulan deneysel yaralar üzerinde morfolojik, biyokimyasal ve biyomekanik yönden düzeltici rol oynadığı ortaya koyulmuştur. Anahtar kelimeler: Pistacia atlantica, yara iyileşmesi, histopatoloji, biomekanik, deri Objectives: This study has been undertaken to investigate the antioxidant activity of the gel formulation from Pistacia atlantica oil extraction on enzymatic antioxidants in experimental wound created in rats. Materials and Methods: Under anesthesia, a square-shaped skin defect (2x2 cm) was created aseptically by surgical incision. Then, animals were randomly allocated to four groups (I-untreated controls, II-topically treated with base gel, III-topically treated with 5% gel, IV-topically treated with 10% gel). Results:The results suggest that topical application of Pistacia atlantica oil gels improved reepithelialization with continuous stratum basalis and a mature granulation tissue and adnexa (hair follicles and sweat gland) compared with control and base gel groups. Treatment with 10% oil gel significantly enhanced the tensile strength, ultimate stress, yield strength and stiffness in this group compared with the control and base gel groups at 21 days post injury. The collagen fibers showed a more organized pattern and the tissue alignment was greater as compared to the control and base gel-treated groups at the same stage. Conclusion:The results suggest that topical application of Pistacia atlantica oil gel improved the morphological, biochemical and biomechanical properties of experimentally-induced wound defects in rats.

“…The results of analysis of inflammatory cells (lymphocytes, macrophages and neutrophils) indicated that AgNPs@ Falcaria ointment regulated significantly ( p ≤ 0.01) the number of these cells at day 10 compared to the other groups (Table ). Macrophages are the most important cells in the inflammatory stage that contribute to elimination of necrotic tissues and bacteria . These cells also contribute to the localization of inflammation process and absorption of fibroblasts to initiate proliferation by releasing some chemotoxic factors.…”

Nanotechnology encompasses the understanding of the fundamental physics, biology, chemistry and technology of nanometre‐scale objects. In recent decades, nanotechnology has grown rapidly owing to its widespread application in science and industry. The aim of the work reported was the green synthesis and chemical characterization of silver nanoparticles from aqueous extract of Falcaria vulgaris leaves (AgNPs@Falcaria) and evaluation of their cytotoxicity and antioxidant, antibacterial, antifungal and cutaneous wound healing effects under in vitro and in vivo conditions. These nanoparticles were characterized using Fourier transform infrared and UV–visible spectroscopies, scanning and transmission electron microscopies and atomic force microscopy. 2,2‐Diphenyl‐1‐picrylhydrazyl free radical scavenging experiments were conducted to evaluate the antioxidant potential, which indicated similar antioxidant potentials for AgNPs@Falcaria and butylated hydroxytoluene. The synthesized AgNPs@Falcaria had great cell viability dose‐dependently, indicating their non‐toxicity. Minimum inhibitory, minimum bactericidal and minimum fungicidal concentrations were determined by macro‐broth dilution assay. The data were analysed using SPSS software (Duncan post hoc test). AgNPs@Falcaria revealed higher antibacterial and antifungal activities than many standard antibiotics (p ≤ 0.01). Also, AgNPs@Falcaria prevented the growth of all bacteria at 2–8 mg ml−1 concentrations and removed them at 4–16 mg ml−1 concentrations (p ≤ 0.01). AgNPs@Falcaria inhibited the growth of all fungi at 2–4 mg ml−1 concentrations and destroyed them at 4–8 mg ml−1 concentrations (p ≤ 0.01). For in vivo experiments, after creating a cutaneous wound, rats were randomly divided into six groups: untreated control, treatment with eucerin basal ointment, treatment with 3% tetracycline ointment, treatment with 0.2% AgNO3 ointment, treatment with 0.2% F. vulgaris ointment and treatment with 0.2% AgNPs@Falcaria ointment. Use of AgNPs@Falcaria ointment in the treatment groups substantially decreased (p ≤ 0.01) the wound area, total cells, neutrophils and lymphocytes and markedly raised (p ≤ 0.01) wound contracture, hydroxyproline, hexosamine, hexuronic acid, fibrocytes and fibrocyte/fibroblast ratio compared to the other groups. In summary, the synthesized AgNPs@Falcaria revealed non‐cytotoxicity and antioxidant, antibacterial, antifungal and cutaneous wound healing activities in a dose‐dependent manner.

“…Tarantula cubensis has also been shown to regulate different stages of inflammation in order to increase the healing response at further stages of tendon healing [8,11]. Garlic and sylimarin has been shown to be anti-inflammatory and antioxidant agents who their effectiveness on wound healing have been extensively described [115,116]. Several other agents such as vitamin C, non-steroidal anti-inflammatory agents such as indomethacin and celecoxib have been shown to regulate the inflammation and are effective in the healing quality [1,117,118].…”

Tendons transmit forces from muscle to bone and provide the joint function and ligaments transmit forces from bone to bone and provide joint stability. Tendon and ligament injuries have high incidence and management of tendon and ligament injuries is technically demanding because the healing response of these soft connective tissues is low. In addition, number of the available options to be considered as tissue replacement for large defects is low and healing of tendon and ligaments is faced to significant limitations. Among the available options, autografts are still gold standard but all the auto-allo and xenografts have their own limitations. Tissue engineering is a newer option but it is still primitive to be applicable extensively, in clinical setting. Tissue engineering could be divided into four categories including scaffolds, healing promotive factors, stem cells and gene therapy. To be able to have a good judgment regarding the management of tendon and ligament injuries, it is crucial to have a basic knowledge of tendon and ligament healing and regeneration. In this review, we discussed various types of tendon and ligament injuries and their incidence, and introduced the available and future options in managing large and massive tendon and ligament injuries. We specifically discussed the tissue engineering and it's advantageous and disadvantageous. To give a better clarification for the readers, we described different phases and cascades of tendon and ligament healing, modeling and remodeling, host-graft interaction after implantation of the graft and various types of prosthetic implants and finally provided some suggestions for the future investigations.
