Topical application of platelet-derived growth factor-BB (PDGF-BB) is considered to accelerate tissue repair of impaired chronic wounds. However, the vast literature is plagued with conflicting reports of its efficacy in animal models and this is often influenced by a wide array of experimental variables making it difficult to compare the results across the studies. To mitigate the confounding ...

Wound healing proceeds by a number of (partially) overlapping steps: bleeding, blood clotting, removal of contaminants and bacteria, wound closure by cell mitosis and migration towards the wound center, repair of the vascular network, and wound contraction along lines of equal tension. We consider a model due to Adam [1] for the closure of a wound. The model is based on an epidermal growth fact...

Wound healing and repair are the most complex biological processes that occur in human life. After injury, multiple biological pathways become activated. Impaired wound healing, which occurs in diabetic patients for example, can lead to severe unfavorable outcomes such as amputation. There is, therefore, an increasing impetus to develop novel agents that promote wound repair. The testing of the...

BACKGROUND Staphylococcus aureus is one of the most causative organisms in the skin wound infections. Development of resistant S. aureus to current treatments in individuals with low immunity is a global concern. The aim of this study was to evaluate the efficacy of herbal formulation against skin wound infection. METHODS The efficacy of herbal formulation containing Oliveria decumben...

Natural products have numerous medicinal applications and play important roles in the biology of the organisms that accumulate them. Flavonoids are one large group of natural products with a diverse number of functions in plants and in human health. The isolates of the flowers of Ipomoea carnea (Family: Convolvulaceae) was screened for wound-healing activity on the male wistar rats by Excision ...

The present study was performed to substantiate the traditional claim of the wound healing activity of stem bark of Albizzia lebbeck Linn. in rats. The effects of aqueous and ethanolic extracts of stem bark of A. lebbeck (5% and 10% w/v topically and 250 mg/kg and 500 mg/kg p.o.) on excision, incision and dead space wound model were examined. The extracts were administered orally for 10 days fo...

The complex interactions that characterize acute wound healing have stymied the development of effective therapeutic modalities. The use of computational models holds the promise to improve our basic approach to understanding the process. By modifying an existing ordinary differential equation model of systemic inflammation to simulate local wound healing, we expect to improve the understanding...

Wound healing is a complex biological process which involves many cell types and biochemical signals and which progresses through multiple, overlapping phases. In this manuscript, we develop a model of collagen accumulation as a marker of wound healing. The mathematical model is a system of ordinary differential equations which tracks fibroblasts, collagen, inflammation and pathogens. The model...

The wound healing effect of two calcium channel blockers, nifedipine and amlodipine was studied in rats using incision and excision wound models. In incision wound, two straight paravertebral skin thickness incision were made and on tenth day skin tensile strength was measured by using continuous water flow technique. In excision wound, circular piece of skin excised in its full thickness and w...

Propolis is a resinous, sticky substance that bees collect from conifer buds and use to repair cracks in their hives. Propolis was used in folk medicine as early as 300 BC as an anti-inflammatory drug and wound healing agent. We studied the effect of Propolis on wound healing in albino rats. Twenty male albino rats had a linear 3 cm incision made over skin of back. The animals were randomly div...
