The mechanisms underlying collective migration, or the coordinated movement of a population of cells, are not well understood despite its ubiquitous nature. As a means to investigate collective migration, we consider a wound healing scenario in which a population of cells fills in the empty space left from a scratch wound. Here we present a simplified mathematical model that uses reaction-diffu...

PURPOSE To present the wound care practitioner with a model for the assessment and treatment of wound-related pain. TARGET AUDIENCE This continuing education activity is intended for physicians and nurses with an interest in wound care and related disorders. OBJECTIVES After reading this article and taking this test, the reader should be able to: 1. Discuss the pathophysiology of chronic pa...

Exogenous nitric oxide donors such as DETA NONOate, spontaneously release nitric oxide. This study aimed to investigate the effect of DETA NONOate as a nitric oxide releasing drug on the rate of collagen synthesis during the impaired wound healing in a rat model of diabetes. Twelve male Sprague–Dawley rats were transferred into separate metabolic cages. Nine days before wounding, the rats were ...

Objective: The present research article was conducted to study the toxicity profile, antioxidant potential and wound healing activity of ethanolic leaves extract of Hibiscus rosa-sinensis L. (ELEHR). Materials and Methods: In-vitro antioxidant properties were assessed using DPPH radical scavenging activity, Nitric oxide scavenging activity, and superoxide radical scavenging activity. Acute toxi...

The methanol extract of Alternanthera brasiliana Kuntze (Family: Amaranthaceae) leaf was investigated for its wound healing effect by excision wound model (in vivo) in aged Sprague Dawley rats. In excision wound model, compared to the control group, percent contraction of wound was significantly (P < 0.01) higher in A. brasiliana-treated group (5% w/w ointment). The collagen, elastin, and hydro...

silymarin, an extract from silybum marianum, has been shown to have antioxidant properties. however, there is no scientific report on wound healing activity of the silymarin. the purpose of this study was to evaluate the effect of topical administration of silymarin on excision wound healing in rats. excision wounds were made on the back of rats. rats were divided into three groups, as control,...

background: in developing new products for skin care and wound treatment, biocompatibility plays a major role in the choice of ingredients. thymol, an essential oil extracted from thyme plant, exhibits outstanding antibacterial properties, but more importantly, it proves to be much more compatible to skin cells in comparison to some conventionally used antibiotic drugs and chemicals. objective:...

Wound healing is a complex process with many components and interrelated processes on a microscopic level. This paper addresses a macroscopic view on wound healing based on an energy conservation argument coupled with a general scaling of the metabolic rate with body mass M as γ M where 1 0 < < γ . Our three main findings are 1) the wound healing rate peaks at a value determined by γ alone, sug...

The wound healing effect of methanolic extract of the root of aegle marmelos was evaluated in the form of an ointment with two different concentrations (5% and 10% w/w in simple ointment base) in excision wound model and incision wound model in rats. In both the concentrations, the extract ointment produced a significant response in both the wound types tested, as evidenced by its wound contrac...
