Abstract In this study, we aimed to evaluate the therapeutic effects of autologous platelet-rich plasma (PRP) on deep partial-thickness burns in Bama pigs. Deep partial-thickness burn wounds were created on the back of Bama pigs. The reepithelialization time was compared between the PRP and control groups. The mean score of Ki67 (+) cells and α-SMA (+) vessels, the mean thickness of epidermis and dermis of the healing wounds were determined via H&E staining and immunohistochemical assay. The levels of the growth factors epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were examined by ELISA. Our data showed that the time to wound reepithelialization was shorter in the PRP group compared with the control group. The thickness of the epidermis was larger in the PRP group compared with the control group. On the 7th and 14th days after the treatment, the mean score of Ki67 (+) cells and α-SMA (+) vessels were higher in the PRP group compared with the control group. The PRP group showed higher levels of growth factors (EGF, bFGF, and VEGF) compared with the control group by ELISA. The results indicated that PRP could improve wound healing process of deep partial-thickness burns in Bama pigs. The PRP increased the thickness of epidermis of the healed wounds, cell proliferation, and angiogenesis. We demonstrated that applying PRP had a greater potential for the treatment of deep partial-thickness burns.

The wound healing process of the soft tissue aims to accelerate the closing of the wound by recurring, restoring the function, and minimizing the scar tissue. This process has to occur in the surgery process to obtain better-wound healing. The aim of this study was to know the stimulation effect of the wound dressing to accelerate the wound healing process of the soft tissue using Collagen (amino acid) and Amnion (proteinase inhibitors). This true experimental study was done to 36 mice (Sprague Dawley) that were divided into three different groups, two groups were the treatment groups and one group was the control group. Each group was adapted in Pathology Laboratory of Faculty of Veterinary Medicine Bogor Agricultural University. All of the mice were injured on the skin by incising the right side of the back for 2 cm in length and 4 mm in depth and then cleaned with 0.9% NaCl solution. To the first group of treatment, the wound was applicated by Amnion, and the second group was applicated by Collagen. Each 4 mice of all group were a termination by ether and encryption on the wounded tissue was conducted on day 3rd, 7th, and 14th. Assessment for a number of fibroblast and collagen synthesis on the wound of back tissue was conducted with the histological examination by painted using hematoxylin-eosin. The results concluded that Collagen application was influencing the mean of fibroblast higher than Amnion, and the lowest was controlled with statistically significant. The mean of collagen used Collagen lower than Amnion, and the lowest was control with statistically significant. It could be concluded that collagen application was preeminent in increasing the productivity of the fibroblast, as well as in developing forms of the collagen synthesis compared with Amnion and control.

Abstract Background Collagen is the most abundant structural protein in the mammalian connective tissue and represents approximately 30% of animal protein. The current study evaluated the potential capacity of collagen extract derived from Nile tilapia skin in improving the cutaneous wound healing in rats and investigated the underlying possible mechanisms. A rat model was used, and the experimental design included a control group (CG) and the tilapia collagen treated group (TCG). Full-thickness wounds were conducted on the back of all the rats under general anesthesia, then the tilapia collagen extract was applied topically on the wound area of TCG. Wound areas of the two experimental groups were measured on days 0, 3, 6, 9, 12, and 15 post-wounding. The stages of the wound granulation tissues were detected by histopathologic examination and the expression of vascular endothelial growth factor (VEGF), and transforming growth factor (TGF-ß1) were investigated using immunohistochemistry. Moreover, relative gene expression analysis of transforming growth factor-beta (TGF-ß1), basic fibroblast growth factor (bFGF), and alpha-smooth muscle actin (α-SMA) were quantified by real-time qPCR. Results The histopathological assessment showed noticeable signs of skin healing in TCG compared to CG. Immunohistochemistry results revealed remarkable enhancement in the expression levels of VEGF and TGF-β1 in TCG. Furthermore, TCG exhibited marked upregulation in the VEGF, bFGF, and α-SMA genes expression. These findings suggested that the topical application of Nile tilapia collagen extract can promote the cutaneous wound healing process in rats, which could be attributed to its stimulating effect on recruiting and activating macrophages to produce chemotactic growth factors, fibroblast proliferation, and angiogenesis. Conclusions The collagen extract could, therefore, be a potential biomaterial for cutaneous wound healing therapeutics.

Partial Thickness Burns

Abstract An ideal dressing should ensure that the wound remains moist with exudates but not macerated. Currently, there is no dressing available to suit all wounds, at all stages of the healing process. Although silver-containing dressings are the gold standard for burn wound care, few high-level trials have been completed comparing the clinical utilities of these dressings. In our study, five different types of wound dressings: carboxymethyl cellulose hydrofiber dressing with ionized silver (CMCH-Ag), polyethylene-polyethylene terephthalate aqua fiber dressing with elementary silver (PPAF-Ag), calcium alginate (CA), calcium + zinc alginate (CZA), and 0.2% nitrofurazone-embedded (NF) gauze dressings were compared in regard to histopathological parameters. Children aged between 0 and 18 years with small or middle-sized partial-thickness burns that affected less than 30% of the total body surface area were included in this study. The study groups (CMCH-Ag, PPAF-Ag, CA, and CZA) and the control group (NF) were randomly attained. Wound healing was evaluated by punch biopsies on the 21st day. The thickness of the stratum corneum and the epithelium, the number of papillae, and the papillary length were calculated and compared. The histological parameters of healing, except the stratum corneum thickness, did not show any statistical significance among the groups (P > .05). The dressings that included silver, calcium, or zinc showed useful and similar effects in noninfective burn wounds when compared with nitrofurazone-only dressings. Thus, it may be concluded that silver-containing wound dressings should not be considered as the gold standard in noninfective partial-thickness burn wounds in children.

Background: Diabetic ulcer is an open wound on the skin layer to the dermis due to hyperglycemia and neuropathy. This condition often causes infection and becomes an inhibitor in the wound healing process. Red fruit oil soap can be used as an alternative cleansing to reduce the number of bacterial colonies and accelerate the wound healing process.Aims: This present study aimed to observe the effect of red fruit oil soap in the cleansing process to reduce the number of bacterial colonies and the wound healing process in grade II Diabetic ulcer patientsMethods: This is a quasi-experimental study with the pre-test post-test non-equivalent control group design. Wound cleansing in the intervention group used 0.9% NaCl solution and red fruit oil soap with a pH of 5.74, while the wound cleansing in the control group used 0.9% NaCl solution. Bacterial colonies were assessed and the type of bacteria was observed by the swab method. The wound healing was assessed with Bates-Jensen Wound Assessment Tool (BWAT) instrument for 14 days with observations every 3 days. Analysis test used Mann Whitney and Repeated Measure ANOVA.Results: There was no difference in the mean of the number of bacterial colonies between the wounds that were cleansed with 0.9% NaCl solution and red fruit oil soap and the wounds which were cleansed by using 0.9% NaCl solution (p> 0.05). The mean of the number of colonies in the intervention group until the 14th day reduced by 3.14x106 and in the control group was reduced h 1.40x106. There was a significant decrease in the wound healing scores in each group, in each assessment for 14 days.Conclusion: This study found that the wound cleansing using red fruit oil soap and 0.9% NaCl solution could reduce the number of bacterial colonies on the wound surface and accelerate the wound healing process among patients with grade II diabetic ulcer.

Partial Thickness Burn

Backgrounds: The body has its own bioelectric system that influences wound healing. Wireless Micro Current Stimulation (WMCS) or Electrical Stimulation (ES) is defined as the use of an electrical current to transfer energy to a wound. The type of electricity transferred is controlled by the electrical source. Although scarce, there have been studies proposing that this type of electricity increased healing rate of various wounds. However the effect of this electrical stimulation on burn wounds has not yet been studied.Patient and Methods: We present case series of superficial and deep partial thickness burns treated with ES and examine its effect on healing process. Six cases of second degree burn admitted to Cipto Mangunkusumo General Hospital (RSCM) from March–May 2011. They were chosen randomly to be treated with WMCS/ES. We applied the stimulation on the wound one hour daily. The wound was cleansed conventionally with moist gauze before and after the stimulation.Results: All the patients reported that they feel comfort during and after the application. We found epithelialization within 6 to 9 days. However we cannot determined if the WCMS/ES induce faster wound healing, because we do not compare it with other treatment. Summary: From six cases that we studied, we concluded that, the use of this WCMS/ES could have an effect of the epithelialization within 6-9 days. All the patients reported that they feel comfort during and after the application of WMCS/ES.

Corneal Epithelial

Ocular chemical burns are potentially blinding ocular injuries and require urgent management. Amniotic membrane (AM) transplantation is an effective surgical treatment, one of the reasons is because AM is a rich source of growth factors that can promote epithelialization and wound healing. However, growth factors will be gradually lost and insufficient after preparation process and long-time storage, leading to unsatisfactory therapeutic effects. Herein, we present a modified AM (AM-HEP) for the supplement and sustained release of growth factor by surface grafting heparin for treatment of ocular chemical burns. Heparin grafting rate and stability, microstructure, physical property, and sustained release of epithelial growth factor (EGF) of AM-HEP were characterized. Biocompatibility and ability to promote corneal epithelial cell growth and migration were evaluated and compared with a biological amnion, which is available on the market in vitro. The therapeutic effects of AM-HEP combined with EGF (AM-HEP@EGF) in vivo had been evaluated in a model of mouse corneal alkali burn. The results indicated that heparin was introduced into AM and maintain stability over 3 weeks at 37°C. The modification process of AM-HEP did not affect microstructure and physical property after comparing with non-modified AM. EGF could be combined quickly and effectively with AM-HEP; the sustained release could last for more than 14 days. AM-HEP@EGF could significantly promote corneal epithelial cell growth and migration, compared with non-modified AM and control group. Faster corneal epithelialization was observed with the transplantation of AM-HEP@EGF in vivo, compared with the untreated control group. The corneas in the AM-HEP@EGF group have less inflammation and were more transparent than those in the control group. The results from in vitro and in vivo experiments demonstrated that AM-HEP@EGF could significantly enhance the therapeutic effects. Taken together, AM-HEP@EGF is exhibited to be a potent clinical application in corneal alkali burns through accelerating corneal epithelial wound healing.

Abstract Growth factors have recently gained clinical importance for wound management. Application of recombinant growth factors has been shown to mimic cell migration, proliferation, and differentiation in vivo, allowing for external modulation of the healing process. Perioperative drug delivery systems can enhance the biological activity of these growth factors, which have a very short in vivo half-life after topical administration. Although the basic mechanisms of these growth factors are well understood, most have yet to demonstrate a significant impact in animal studies or small-sized clinical trials. In this review, we emphasized currently approved growth factor therapies, including a sustained release system for growth factors, emerging therapies, and future research possibilities combined with surgical procedures. Approaches seeking to understand wound healing at a systemic level are currently ongoing. However, further research and consideration in surgery will be needed to provide definitive confirmation of the efficacy of growth factor therapies for intractable wounds.
