A correlative bright-field and hyperspectral analysis of full-thickness, cutaneous wounds in a porcine model was undertaken to investigate the efficacy of hyperspectral imaging as an alternate method for wound identification. Analysis of a randomly selected specimen yielded distinct spectral signatures for cutaneous regions of interest including the epidermis, injured dermis, and normal dermis....

It has been postulated that an inflammatory response after cutaneous wounding is a prerequisite for healing, and inflammatory cytokines, such as interleukin-6 (IL-6), might be intimately involved in this process. IL-6-deficient transgenic mice (IL-6 KO) displayed significantly delayed cutaneous wound healing compared with wild-type control animals, requiring up to threefold longer to heal. This...

Sonic hedgehog (SHH) plays an important role in postnatal tissue repair. The present study tested the hypothesis that impaired SHH pathway results in delayed wound healing by suppressing cutaneous nitric oxide (NO) function in type 1 diabetes. Adult male C57/B6 mice and streptozotocin (STZ)-induced type 1 diabetic mice were used. Although cutaneous SHH and Patched-1 (Ptc-1 encoded by PTCH, PTCH...

Cutaneous wounds heal more slowly in elderly males than in elderly females, suggesting a role for sex hormones in the healing process. Indeed, androgen/androgen receptor (AR) signaling has been shown to inhibit cutaneous wound healing. AR is expressed in several cell types in healing skin, including keratinocytes, dermal fibroblasts, and infiltrating macrophages, but the exact role of androgen/...

BACKGROUND Wound healing represents a dynamic process involving directional migration of different cell types. Chemokines, a family of chemoattractive proteins, have been suggested to be key players in cell-to-cell communication and essential for directed migration of structural cells. Today, the role of the chemokine network in cutaneous wound healing is not fully understood. Unraveling the ch...

Dogs with cutaneous wound were selected and randomly divided into two groups, to study the efficacy of fish scales extracted collagen biocasings on cutaneous wound healing. The wounds in both groups of dogs were protected with sterile external bandage after cleaning with normal saline to prevent infection. The efficacy of biocasings on wound healing was studied based on gross, physiological, he...

OBJECTIVE Autologous platelet rich plasma is an advanced wound therapy used in hard-to-heal acute and chronic wounds. To better understand the use and clinical outcomes of the therapy, a systematic review of the published literature in cutaneous wounds was performed. METHODS Electronic and hand searches for randomized controlled trials and comparative group studies using platelet rich plasma ...

Treatment of wounds is very important and was subject of different investigations. In this regard, natural substance plays crucial role as complementary medicine. Various studies reported that aloe vera has useful effects on wounds especially cutaneous wounds healing. Therefore in the current review, we examined the effect of aloe vera on cutaneous wound healing and concluded that although aloe...
