BACKGROUND Tannins extracted from immature fruits of Terminalia chebula Fructus Retz. are considered as effective components promoting the process of wound healing. The objective of this study is to explore the optimal extraction and purification technology (OEPT) of tannins, while studying the use of this drug in the treatment of a cutaneous wound of rat as well as its antibacterial effects. ...

Wound healing consists of a complex series of convoluted processes which involve renewal of the skin after injury. ROS are involved in all phases of wound healing. A balance between oxidative and antioxidative forces is necessary for a favorable healing outcome. Astaxanthin, a member of the xanthophyll group, is considered a powerful antioxidant. In this study, we investigated the effect of top...

The process of wound healing can be divided into substrate, proliferative, and remodeling phases. The basic biologic and physiologic events which transpire during these stages are examined in detail. Particular emphasis is placed on the interactions between platelets, macrophages, and other inflammatory cells, and fibroblasts in the healing wound. Recent advances in the roles played by interleu...

Sulfur mustard is an alkylating chemical warfare agent that primarily affects the eyes, skin, and airways. Sulfur mustard injuries can take several months to heal, necessitate lengthy hospitalizations, and result in significant cosmetic and/or functional deficits. Historically, blister aspiration and/or deroofing (epidermal removal), physical debridement, irrigation, topical antibiotics, and st...

Mast cells are suggested to participate in wound healing, but their specific role has remained obscure. Mast cells are a rich source of inflammatory mediators, such as histamine, proteoglycans, the proteases tryptase and chymase, lipids, growth factors and cytokines. Among these mediators, there are many that have effects on cell growth, tissue turnover and repair. The aim of this study was to ...

Heparan sulfate glycosaminoglycans (HS-GAGs) are not only the structural elements of tissue architecture but also regulate the bioavailability and transduction pathways of heparan sulfate-bound polypeptides released by cells or the extracellular matrix. Heparan sulfate-bound polypeptides include inflammatory mediators, chemokines, angiogenic factors, morphogens, and growth-promoting factors tha...
