Wound healing/cicatrization is a complex series of intricate processes that involve renewal of skin/epidermis after injury. A large number of ethno-medicinal plants/plant extracts are used by tribal and folklore traditions in developing world for the treatment of wounds, burns and cuts in distinct appearances. Moreover, plants/plant extracts have a significant history and successful clinical track record as indigenous drugs in wound repair systems. This review provides detailed information on molecular and cellular mechanism of plant/plant extracts on wound healing applications and further analyses the opportunities and scope with its future openings and prospects owing to the multifaceted challenges attached with neo-tissue regeneration...

Allografts are in constant demand, not only for burn victims, but also for all open wounds as "biological dressings". Tissue quality and security are two of the major concerns of Tissue Banks. There are limited studies published. There has been extensive discussion on the subject of preservation methods for cadaver skin. Most literature available comes from clinical reports. In this research, the authors compared 85% glycerolized non irradiated skin allografts with three glycerolized irradiated skin allografts (using different glycerol concentrations 50%, 70% and 85%)...

An ideal wound dressing ensures a moist environment around the wound area and absorbs exudates from the wound surface. Topical application of bromelain to incised wounds has been shown to reprogram the wound microenvironment to promote effective tissue repair. Combining the characteristics of hydrogels and bromelain is therefore of great interest. Herein, we describe the development of a hydrogel, formulated using alginate and Arabic gum, for bromelain loading and release. The hydrogel formulation was evaluated using response surface methodology, considering the pH value and the concentration of alginate and Arabic gum...

INTRODUCTION: The assessment of burn depth can be challenging even to the experienced burn clinician. Clinical assessment is most widely used to determine burn depth. Because of this subjective nature, various imaging modalities have been invented. The use of photospectometry as a novel technique in burn wound depth analysis has been previously described but the literature is very limited. METHODOLOGY: We carried out a single blinded non-randomized comparative study of healing potential of 50 burn wounds between tissue spectrophotometry analysis versus clinical evaluation...

Transdifferentiation of quiescent dermal fibroblasts to secretory myofibroblasts has a central role in wound healing and pathological scar formation. This myofibroblast transdifferentiation process involves TGFβ-induced de novo synthesis of alpha smooth muscle cell actin (αSMA)+ fibers that enhance contractility as well as increased expression of extracellular matrix (ECM) proteins, including collagen and fibronectin. These processes are mediated upstream by the reactive oxygen species (ROS)-producing enzyme Nox4, whose induction by TGFβ is incompletely understood...

Early excision and skin grafting is the principle treatment for a burned hand although there are occasions when it cannot be done such as severe general condition, delayed consultation, and the lack of a definitive assessment of burn depth. This study analyzes the factors that affected function after a delayed excision and skin graft for hands with a deep dermal burn. This study retrospectively evaluated 43 burned hands that required a delayed excision and split-thickness skin graft on the dorsal side. Cases were required to only have split-thickness skin grafting from the dorsum of the hand and fingers distally to at least the proximal interphalangeal joint at least 8 days after the injury...

This report shows that the antimicrobial peptide (AMP) Epinecidin-1 (Epi-1) efficiently heals MRSA-infected heat burn injuries and provides protection from infection in a pig model. The presence of an optimal level of Epi-1 induces cell proliferation by promoting cell cycle progression through an increase in S-phase cells. Epi-1 also induces proliferation to cover the wounded region in an in vitro cell proliferation assay using immortalized human epithelial HaCaT cells. Next, the in vivo wound healing efficiency of Epi-1 was tested in heat-burned pig skin infected with MRSA under in vivo conditions...

Despite tremendous advances in critical care, multiple-organ failure continues to be a significant problem. However, in recent years, far fewer patients with multiple-organ failure die early, but many experience ongoing immune dysregulation and are developing persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Most PICS patients are discharged to nonhome destinations, fail to rehabilitate, and succumb to indolent death. From a nutrition perspective, patients with PICS experience persistent inflammation-induced cachexia despite evidenced-based recommended intensive care unit nutrition support...

Low temperature plasma (LTP) coagulation equipment, which avoids causing burn injuries to patients, has been introducing into minimally invasive surgery. The mechanism by which this equipment stops bleeding is to directly occupy the injury with the formed blood clots, and different from the mechanism of the common electrical hemostatic devices that cauterize the tissues around the bleeding to stem the blood flow. A noteworthy point is that LTP treatment with our equipment is not confined only to the blood coagulation system, but it has significant effects on the other blood components to form clots with or without hemolysis, and that there is a plasma current threshold that determines whether the treatment makes stable clots...

Impaired corneal healing is still a major cause of blindness. As RAGE (receptor for advanced glycation endproducts) is involved in inflammation and wound healing in other tissues, we here investigated its relevance for corneal wound healing. Corneal re-epithelialization after alkaline injury was analysed in an ex-vivo approach with cultured, enucleated eyes from mice either of the C57Bl/6 NChR genotype (RAGE+/+) and mice of the same strain lacking the RAGE gene (RAGE-/-). The wound area was determined time dependently by fluorescence imaging using fluorescein staining...

Objective: To investigate the repair mechanisms of the wounds with bone exposed by artificial dermis transplantation. Methods: Seventy two rabbits were randomly divided into 3 groups of 24 rabbits, the wound model was made on the top of head. In the skin defect group (SD group), skin was removed and skull periosteum was retained. In the periosteal defect group (PD group), the skin and skull periosteum were both removed, and the skull was exposed. In the skull burn group (SB group), after the periosteum was removed, the exposed skull bone was burned out with electric iron to cause skull surface necrosis, then the artificial dermis transplantation were performed in each group...
