Marine polysaccharides are believed to be promising wound-dressing nanomaterials because of their biocompatibility, antibacterial and hemostatic activity, and ability to easily shape into transparent films, hydrogels, and porous foams that can provide a moist micro-environment and adsorb exudates. Current efforts are firmly focused on the preparation of novel polysaccharide-derived nanomaterials functionalized with chemical objects to meet the mechanical and biological requirements of ideal wound healing systems. In this contribution, we investigated the characteristics of six different cellulose-filled chitosan transparent films as potential factors that could help to accelerate wound healing. Both microcrystalline and nano-sized cellulose, as well as native and phosphorylated cellulose, were used as fillers to simultaneously elucidate the roles of size and functionalization. The assessment of their influences on hemostatic properties indicated that the tested nanocomposites shorten clotting times by affecting both the extrinsic and intrinsic pathways of the blood coagulation system. We also showed that all biocomposites have antioxidant capacity. Moreover, the cytotoxicity and genotoxicity of the materials against two cell lines, human BJ fibroblasts and human KERTr keratinocytes, was investigated. The nature of the cellulose used as a filler was found to influence their cytotoxicity at a relatively low level. Potential mechanisms of cytotoxicity were also investigated; only one (phosphorylated microcellulose-filled chitosan films) of the compounds tested produced reactive oxygen species (ROS) to a small extent, and some films reduced the level of ROS, probably due to their antioxidant properties. The transmembrane mitochondrial potential was very slightly lowered. These biocompatible films showed no genotoxicity, and very importantly for wound healing, most of them significantly accelerated migration of both fibroblasts and keratinocytes.

: Wound healing is a process which starts with inflammatory response after damage occurrence. This process happens by restoring the wound surface coating tissue, migrating fibroblasts to form the needed collagen, forming a healing tissue and finally contortion and extraction of the wound. Today, various drugs are used to heal the wound. However, the used drugs to repair wounds have some defects and side effects. In spite of all attempts to accelerate wound healing definitely, no safe drug has been introduced for this purpose. Therefore, the necessity of identifying herbal plants in ethnopharmacology and ethnobotany documents with healing effect is felt essential. In this article we tried to review and present Iranian effective medicinal plants and herbal compounds used for wound healing. Searching was performed on databases including ISI Web of Science, PubMed, PubMed Central, Scopus, ISC, SID, Magiran and some other databases. The keywords used included wound healing, skin treatment, medicinal plants, ethnobotany, and phytotherapy. In this regard, 139 effective medicinal plants on wound healing were identified based on ethnopharmacology and ethnobotanical sources of Iran. Medicinal plants such as Salvia officinalis, Echium amoenum, Verbascum spp., G1ycyrrhiza glabra, Medicago sativa, Mentha pulegium, Datura stramonium L., Alhagi spp., Aloe vera, Hypericum perforatum, Pistacia atlantica and Prosopis cineraria were the most important and effective medicinal plants on wound healing in Iran. These native Iranian medicinal plants are full of antioxidants and biological compounds and might be used for wound healing and preparation of new drugs.

Abstract Wound healing dressing is increasingly needed in clinical owing to the large quantity of skin damage annually. Excessive reactive oxygen species (ROS) produced through internal or external environmental influences can lead to lipid peroxidation, protein denaturation, and even DNA damage, and ultimately have harmful effects on cells. Aiming to sufficiently contact with the wound microenvironment and scavenge ROS, superabsorbent poly (acrylic acid) and antioxidant poly (ester amide) (PAA/PEA) hybrid hydrogel has been developed to enhance wound healing. The physical and chemical properties of hybrid hydrogels were studied by Fourier-transform infrared (FTIR) absorption spectrum, compression, swelling, degradation, etc. Besides, the antioxidant properties of hybrid hydrogels can be investigated through the free radical scavenging experiment, and corresponding antioxidant indicators have been tested at the cellular level. Hybrid hydrogel scaffolds supported the proliferation of human umbilical vein endothelial cells and fibroblasts, as well as accelerated angiogenesis and skin regeneration in wounds. The healing properties of wounds in vivo were further assessed on mouse skin wounds. Results showed that PAA/PEA hybrid hydrogel scaffolds significantly accelerated the wound healing process through enhancing granulation formation and re-epithelialization. In summary, these superabsorbent and antioxidative hybrid hydrogels could be served as an excellent wound dressing for full-thickness wound healing.

Abstract Traditional medicine credits yarrow (Achillea millefolium) with the ability to accelerate wound healing. The purpose of this research was to determine the effects of yarrow on the epithelization of the lower leg venous ulcers. The study included 39 patients with venous leg ulcers. They were divided into two groups: the first (experimental) group of patients were treated with an ointment containing 7.5% of yarrow extract. In the second (control) group, saline solution dressings were applied to ulcers, within the period of three weeks. In the experimental group, at the beginning of the therapy, the total surface of all the ulcers was 44736 mm2. After three weeks, the total surface of all the ulcers was 27000 mm2 (a decrease of 39.64%). In the control group, at the beginning of the therapy, the total surface of all the ulcers was 46116 mm2. At the end of the study (21 days) the total surface of all the ulcers was 39153 mm2 (a decrease of 15.1%). Herbal preparations are suitable for application in the therapy of venous ulcers, but their efficiency in wound healing is still to be investigated.

Abstract A neck scar contracture can severely and negatively affect the function of mastication, phonic, or breathing and result in neck pain and issues with esthetics. The best way is of course to avoid such contracture by means of non-surgical treatment such as use of a growth factor. The basic fibroblastic growth factor is clinically well proven in decreasing scar formation and improving healing. There are numerous reconstructive methods for neck contracture, especially when the lesions are relatively limited in part of the neck. However, a very severe and full circumferential scar contracture requires extensive reconstruction. The thin groin flap is one of the answers and well matches with the tissue texture and maintains the flexibility. Even with extensive burns and delayed reconstructions due to resuscitation first, the groin area is well preserved and can be safely harvested by dual vasculature systems of the superficial circumflex iliac artery and superficial epigastric artery, which warrant more reliability compared to the perforator flaps in this area. More demanding and stringent forms of the neck burn scar contracture are the sequelae of radiation. A radiation burn or radiation injury can be progressing and hard to heal. Adipose-derived stem cells can reverse the scar contracture as the surrounding tissue is softened and can accelerate wound healing. In this review, different types of neck burn scar contracture and reconstructive methods are summarized, including innovative use of bFGF and ADSCs in the management of difficult wound healing and scar contracture.
