Simple Method

The use of a simple and reproducible model is inevitable for objective statement of the effects of external factors on wound healing. Hence, present study was conducted to establish an excisional model of skin wound healing in corticosteroid treated, and streptozotocine induced diabetic rats as well as to standardized the semi-quantitative and quantitative evaluation of selected parameters. Round full thickness skin wounds were performed on the back of male Sprague-Dawley rats. Animals were sacrificed two, six, and fourteen days after surgery. Sections were stained with hematoxylin-eosin and van Gieson. Both semi-quantitative (wound reepithelization; presence of: inflammatory cells, fibroblasts, new wessels, and collagen) and quantitative methods (polymorphonuclear leucocytes/tissue macrophages ratio, percentage of re-epithelization, area of the granulation tissue) were used to evaluate the histological changes during wound healing. As compared to the control group the wound healing process of both experimental groups was decelerated. Interestingly, wound reepithelization and angiogenesis were significantly inhibited only in the steroid rats while epithelization was accelerated in diabetic rats. In conclusion, when compared to primary sutured wound healing it can be concluded that the excisional model is more appropriate for histological assessment of the effect of various factors on wound healing. In addition, administration of corticosteroids represents simple and inexpensive model of a complex skin wound healing impairment.

This study is designed to assess the effectiveness of bovine urinary bladder submucosa on healing of cutaneous wound in Iraqi goats. A 32 (2X2) cm of full-thickness cutaneous wounds were induced in eight goats, two on each side of the lateral thoracic region. The wounds were divided into two equal groups (16 wounds/ group); treatment group included the wounds on the right side which were treated by covering the wound beds with strips of acellular sterilized bovine urinary bladder matrix. While, the wounds on the left side were left without any treatment (control group). The results were evaluated clinically (along) and histopathologically on 7, 14, 21, and 35 days post-inducing of wounds. The clinical evaluation of treated wounds showed that the wound healing process contraction%, re-epithelization % and total wound healing % were P<0.05 significantly than that of control wounds at 35 days of the study. The histopathological results confirmed that urinary bladder matrix treated wounds have enhanced cellularity, increased vasculature, thick and large granulation tissue suggesting enhanced cutaneous healing, than those in untreated wounds. Depending on the clinical and histopathological findings, this study concluded that a cellular bovine urinary bladder matrix play an important role in stimulation of cutaneous wound healing of goats without signs of immuno-rejection.

Karst and Crinipellis schevczenkovi 31 Buchalo mycelia were investigated for skin wound healing activity in vivo using the excision wound healing model. The extracts were prepared by mixing of 100 mg of powdered mycelium of both mushrooms with 1 mL of sterile distilled water for injections. White albino mice line FVB/Cg., 3 months of age (male), were used for the study. The rate of wound healing and the histology of healed wounds in mice have been studied. Visual method of wound study and histological investigation of skin tissue showed the presence of wound healing potential of G. lucidum and C. schevczenkovi mycelia. The wound healing process was expressed more active on 3th day in case of topical application of C. schevczenkovi mycelium extract, but on 5th day the wound healing effects of both mushroom extracts were almost at the same level and statistically better then results in the control group. Wounds treated with mycelial extracts were covered completely on the 6th day compared with 8th day in control group. Wound healing ability of C. schevczenkovi observed in present investigations for the first time.

Impaired Wound Healing

Impaired wound healing is a major medical challenge, especially in diabetics. Over the centuries, the main goal of tissue engineering and regenerative medicine has been to invent biomaterials that accelerate the wound healing process. In this context, keratin-derived biomaterial is a promising candidate due to its biocompatibility and biodegradability. In this study, we evaluated an insoluble fraction of keratin containing casomorphin as a wound dressing in a full-thickness surgical skin wound model in mice (n = 20) with iatrogenically induced diabetes. Casomorphin, an opioid peptide with analgesic properties, was incorporated into keratin and shown to be slowly released from the dressing. An in vitro study showed that keratin-casomorphin dressing is biocompatible, non-toxic, and supports cell growth. In vivo experiments demonstrated that keratin-casomorphin dressing significantly (p < 0.05) accelerates the whole process of skin wound healing to the its final stage. Wounds covered with keratin-casomorphin dressing underwent reepithelization faster, ending up with a thicker epidermis than control wounds, as confirmed by histopathological and immunohistochemical examinations. This investigated dressing stimulated macrophages infiltration, which favors tissue remodeling and regeneration, unlike in the control wounds in which neutrophils predominated. Additionally, in dressed wounds, the number of microhemorrhages was significantly decreased (p < 0.05) as compared with control wounds. The dressing was naturally incorporated into regenerating tissue during the wound healing process. Applied keratin dressing favored reconstruction of more regular skin structure and assured better cosmetic outcome in terms of scar formation and appearance. Our results have shown that insoluble keratin wound dressing containing casomorphin supports skin wound healing in diabetic mice.

Abstract Background The skin wound healing process is regulated by various cytokines, chemokines, and growth factors. Recent reports have demonstrated that spermine/spermidine (SPD) promote wound healing through urokinase-type plasminogen activator (uPA)/uPA receptor (uPAR) signaling in vitro. Here, we investigated whether the systemic and topical administration of SPD would accelerate the skin wound-repair process in vivo.Methods A skin wound repair model was established using C57BL/6 J mice. SPD was mixed with white petrolatum for topical administration. For systemic administration, SPD mixed with drinking water was orally administered. Changes in wound size over time were calculated using digital photography.Results Systemic and topical SPD treatment significantly accelerated skin wound healing. The administration of SPD promoted the uPA/uPAR pathway in wound sites. Moreover, topical treatment with SPD enhanced the expression of IL-6 and TNF-α in wound sites. Scratch and cell proliferation assays revealed that SPD administration accelerated scratch wound closure and cell proliferation in vitro.Conclusion These results indicate that treatment with SPD promotes skin wound healing through activation of the uPA/uPAR pathway and induction of the inflammatory response in wound sites. The administration of SPD might contribute to new effective treatments to accelerate skin wound healing.

Skin Wound Healing

Chronic nonhealing wounds pose a significant challenge to healthcare system because of its tremendous utilization of resources and time to heal. It has a well-deserved reputation for reducing the quality of life for those affected and represent a substantial economic burden to the healthcare system overall. Earthworms are used as a traditional Chinese medicine, and have been applied pharmacologically and clinically since a long time in China. However, there is paucity in data regarding its wound healing effects. Therefore, we investigated the effect of earthworm extract (EE) on skin wound healing process. The obtained data showed that EE has healing effects on local wound of mice. It decreased the wound healing time and reduced the ill-effects of inflammation as determined by macroscopic, histopathologic, hematologic, and immunohistochemistry parameters. The potential mechanism could be accelerated hydroxyproline and transforming growth factor-β secretion—thus increasing the synthesis of collagen, promoting blood capillary, and fibroblast proliferation. It could accelerate the removal of necrotic tissue and foreign bodies by speeding up the generation of interleukin-6, white blood cells, and platelets. It thus enhances immunity, reduces the risk of infection, and promotes wound healing. All in all, the obtained data demonstrated that EE improves quality of healing and could be used as a propitious wound healing agent.
