    Contribution and role of a pyramid/square box on the wound healing suppressant effect of dexamethasone was studied in rats of either sex using excision wound model to record the wound contraction rate and epithelization period. The results showed enhanced wound contraction rate and decreased epithelization period in the pyramid-exposed rats as compared to controls. Thus, it appears that pyramid environment facilitates the process of wound healing. Also, the wound healing suppressant effects of dexamethasone were significantly reduced.

    PMID: 2696870
    The use of tissue adhesives has been widely studied since the 1960s. Since then they have found use in specialties like plastic surgery, neurosurgery, ENT surgery and dental surgery. Several papers have reported their safe use, both clinically and experimentally, particularly of the newer homologue n-butyl/2-cyanoacrylate (Histoacryl). In this study 43 patients (46 wounds) whose operations involved a groin incision were randomised into two groups for skin closure either with Dexon subcuticular suture (23 wounds) or Histoacryl glue (23 wounds). We found that both sets of wounds healed well with no wound infections or excessive inflammation when assessed at one week and four weeks. However the glued wounds had consistently better cosmesis scores (mean score 4.71 at four weeks) compared to the subcuticular Dexon wounds (mean score 4.00 at four weeks) and P value of less than 0.05. We feel that there is a place for tissue adhesives in skin closure for some general surgical wounds.

    Chronic wounds which include diabetic foot ulcer (DFU), pressure ulcer, and arterial or venous ulcers compel a significant burden to the patients, healthcare providers, and the healthcare system. Chronic wounds are characterized by an excessive persistent inflammatory phase, prolonged infection, and the failure of defense cells to respond to environmental stimuli. Unlike acute wounds, chronic nonhealing wounds pose a substantial challenge to conventional wound dressings, and the development of novel and advanced wound healing modalities is needed. Toward this end, numerous conventional wound-healing modalities have been evaluated in the management of nonhealing wounds, but a multifaceted approach is lacking. Therefore, this review aims to compile and explore the wide therapeutic algorithm of current and advanced wound healing approaches to the treatment of chronic wounds. The algorithm of chronic wound healing techniques includes conventional wound dressings; approaches based on autografts, allografts, and cultured epithelial autografts; and recent modalities based on natural, modified or synthetic polymers and biomaterials, processed mutually in the form of hydrogels, films, hydrocolloids, and foams. Moreover, this review also explores the promising potential of advanced drug delivery systems for the sustained delivery of growth factors, curcumin, aloe vera, hyaluronic acid, and other bioactive substances as well as stem cell therapy. The current review summarizes the convincing evidence for the clinical dominance of polymer-based chronic wound healing modalities as well as the latest and innovative therapeutic strategies for the treatment of chronic wounds.

  4. Development of the PVA/CS nanofibers containing silk protein sericin as a wound dressing: In vitro and in vivo assessment
    Bakhsheshi-Rad HR, Ismail AF, Aziz M, Akbari M, Hadisi Z, Omidi M, et al.
    Int J Biol Macromol, 2020 Apr 15;149:513-521.

    Skin and soft tissue infections are major concerns with respect to wound repair. Recently, anti-bacterial wound dressings have been emerging as promising candidates to reduce infection, thus accelerating the wound healing process. This paper presents our work to develop and characterize poly(vinyl alcohol) (PVA)/chitosan (CS)/silk sericin (SS)/tetracycline (TCN) porous nanofibers, with diameters varying from 305 to 425 nm, both in vitro and in vivo for potential applications as wound dressings. The fabricated nanofibers possess a considerable capacity to take up water through swelling (~325-650%). Sericin addition leads to increased hydrophilicity and elongation at break while decreasing fiber diameter and mechanical strength. Moreover, fibroblasts (L929) cultured on the nanofibers with low sericin content (PVA/CS/1-2SS) displayed greater proliferation compared to those on nanofibers without sericin (PVA/CS). Nanofibers loaded with high sericin and tetracycline content significantly inhibited the growth of Escherichia coli and Staphylococcus aureus. In vivo examination revealed that PVA/CS/2SS-TCN nanofibers enhance wound healing, re-epithelialization, and collagen deposition compared to traditional gauze and nanofibers without sericin. The results of this study demonstrate that the PVA/CS/2SS-TCN nanofiber creates a promising alternative to traditional wound dressing materials.

    Burns, 2012 May;38(3):307-18.
    PMID: 22030441 DOI: 10.1016/j.burns.2011.09.020
    Silver preparations are commonly used for burns, but evidence of their effectiveness remains poorly defined. The aim of the study was to evaluate the effectiveness of silver-containing dressings and topical silver for preventing infection and promoting healing in burns wounds through a meta-analysis of the available evidence. The Cochrane Central Register of Controlled Trials and relevant databases were searched. Drug companies and experts in this field were also contacted. Randomised controlled trials (RCTs) of silver dressings or topical silver (used with dressings) compared with non-silver dressings were eligible for inclusion. We identified 14 RCTs involving 877 participants. One small trial of a silver-containing dressing showed significantly better healing time compared to the control [MD -3.6; 95% CI -4.94 to -2.26 for partial thickness burns and MD -3.9; 95% CI -4.54 to -3.26 for superficial burns]. Topical silver showed significantly worse healing time compared to the non-silver group [WMD 3.96; 95% CI 2.41-5.51] and showed no evidence of effectiveness in preventing wounds infection [WMD 2.48; 95% CI 0.39-15.73]. Our review suggests that silver-containing dressings and topical silver were either no better or worse than control dressings in preventing wound infection and promoting healing of burn wounds.

  6. Safety and efficacy of dermal fibroblast conditioned medium (DFCM) fortified collagen hydrogel as acellular 3D skin patch
    Maarof M, Mh Busra MF, Lokanathan Y, Bt Hj Idrus R, Rajab NF, Chowdhury SR

    Skin substitutes are one of the main treatments for skin loss, and a skin substitute that is readily available would be the best treatment option. However, most cell-based skin substitutes require long production times, and therefore, patients endure long waiting times. The proteins secreted from the cells and tissues play vital roles in promoting wound healing. Thus, we aimed to develop an acellular three-dimensional (3D) skin patch with dermal fibroblast conditioned medium (DFCM) and collagen hydrogel for immediate treatment of skin loss. Fibroblasts from human skin samples were cultured using serum-free keratinocyte-specific media (KM1 or KM2) and serum-free fibroblast-specific medium (FM) to obtain DFCM-KM1, DFCM-KM2, and DFCM-FM, respectively. The acellular 3D skin patch was soft, semi-solid, and translucent. Collagen mixed with DFCM-KM1 and DFCM-KM2 showed higher protein release compared to collagen plus DFCM-FM. In vitro and in vivo testing revealed that DFCM and collagen hydrogel did not induce an immune response. The implantation of the 3D skin patch with or without DFCM on the dorsum of BALB/c mice demonstrated a significantly faster healing rate compared to the no-treatment group 7 days after implantation, and all groups had complete re-epithelialization at day 17. Histological analysis confirmed the structure and integrity of the regenerated skin, with positive expression of cytokeratin 14 and type I collagen in the epidermal and dermal layer, respectively. These findings highlight the possibility of using fibroblast secretory factors together with collagen hydrogel in an acellular 3D skin patch that can be used allogeneically for immediate treatment of full-thickness skin loss.

  7. In Vitro Evaluation of Novel Phenytoin-Loaded Alkyd Nanoemulsions Designed for Application in Topical Wound Healing
    Teo SY, Yew MY, Lee SY, Rathbone MJ, Gan SN, Coombes AGA
    J Pharm Sci, 2017 01;106(1):377-384.
    PMID: 27522920 DOI: 10.1016/j.xphs.2016.06.028
    Phenytoin-loaded alkyd nanoemulsions were prepared spontaneously using the phase inversion method from a mixture of novel biosourced alkyds and Tween 80 surfactant. Exposure of human adult keratinocytes (HaCaT cells) for 48 h to alkyd nanoemulsions producing phenytoin concentrations of 3.125-200 μg/mL resulted in relative cell viability readings using tetrazolium dye 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide of 100% confirming nontoxicity and suggesting cell proliferation activity. Phenytoin-loaded alkyd nanoemulsions generally resulted in higher mean cell viability compared with equivalent concentration of phenytoin solutions, suggesting that the nanoemulsions provided a controlled-release property that maintained the optimum phenytoin level for keratinocyte growth. HaCaT cell proliferation, measured by 5-bromo-2-deoxyuridine uptake, was found to increase following exposure to increasing phenytoin concentration from 25 to 50 μg/mL in solution or encapsulated in nanoemulsions but declined at a drug concentration of 100 μg/mL. An in vitro cell monolayer wound scratch assay revealed that phenytoin solution or nanoemulsions producing 50 μg/mL phenytoin concentration resulted in 75%-82% "scratch closure" after 36 h, similar to medium containing 10% fetal bovine serum as a cell growth promoter. These findings indicate that phenytoin-loaded alkyd nanoemulsions show potential for promoting topical wound healing through enhanced proliferation of epidermal cells.

  8. Ellagic Acid Increases Osteocalcin and Alkaline Phosphatase After Tooth Extraction in Nicotinic-Treated Rats
    Al-Obaidi MM, Al-Bayaty FH, Al Batran R, Ibrahim OE, Daher AM
    Curr Pharm Des, 2016;22(16):2403-10.
    PMID: 27139374
    OBJECTIVES: -To examine the effect of nicotine (Ni) on bone socket healing treated with Ellagic acid (EA) after tooth extraction in rat.

    MATERIALS AND METHODS: Thirty-Two Sprague Dawley (SD) male rats were divided into four groups. The group 1 was administrated with distilled water intragastrically and injected sterile saline subcutaneously. The group 2 was administrated with EA orally and injected with sterile saline subcutaneously. The groups 3 & 4 were subcutaneously exposed to Ni for 4 weeks twice daily before tooth extraction procedure, and maintained Ni injection until the animals were sacrificed. After one month Ni exposure, the group 4 was fed with EA while continuing Ni injection. All the groups were anesthetized, and the upper left incisor was extracted. Four rats from each group were sacrificed on 14(th) and 28(th) days. Tumour necrosis factor alpha (TNFα), Interleukin-1 beta (IL-1β) and Interleukin-6 (IL-6) were applied to assess in serum rat at 14th and 28(th) days. Superoxide dismutase (SOD) and Thiobarbituric acid reactive substances (TBRAS) levels were assessed to evaluate the antioxidant status and lipid peroxidation accordingly after tooth extraction in homogenized gingival maxilla tissue of rat at 14(th) and 28(th) days. The socket hard tissue was stained by eosin and hematoxylin (H&E); immunohistochemical technique was used to assess the healing process by Osteocalcin (OCN) and Alkaline Phosphatase (ALP) biomarkers.

    RESULTS: Ni-induced rats administered with EA compound (Group 4) dropped the elevated concentration of pro-inflammatory cytokines significantly when compared to Ni-induced rats (Group 3) (p<0.05). Ni-induced rats administrated with EA compound (Group 4) showed significant production of SOD and recession in TBRAS level when compared to Ni-induced rats (Group 3) (p<0.05). The immunohistochemistry analysis has revealed that OCN and ALP have presented stronger expression in Ni-induced rats treated with EA (Group 4), as against Ni-induced rats (Group 3).

    CONCLUSION: We have concluded that, Ni-induced rats, treated with EA have exerted positive effect on the trabecular bone formation after tooth extraction in nicotinic rats could be due to the antioxidant activity of EA which lead to upregulate of OCN and ALP proteins which are responsible for osteogenesis.

    Mesenchymal stem cells (MSCs) transplantation seems to be a promising new therapy for diabetic wound healing (DWH), and currently, arrays of MSCs from various sources ranging from umbilical, adipose to dental sources are available as a treatment modality for this disease. However, it now appears that only a fraction of transplanted cells actually assimilate and survive in host tissues suggesting that the major mechanism by which stem cells participate in tissue repair are most likely related to their secretome level. These include a wide range of growth factors, cytokines, and chemokines, which can be found from the conditioned medium (CM) used to culture the cells. Basic studies and preclinical work confirm that the therapeutic effect of CMs are comparable with the application of stem cells. This review describes in detail the wound healing process in diabetes and the cellular and biological factors that influence the process. Subsequently, through a comprehensive literature search of studies related to wound healing in diabetics, we aim to provide an overview of scientific merits of using MSCs-CM in the treatment of diabetic wound as well as the significant caveats, which restricts its potential use in clinical set-ups. To our best knowledge, this is one of the first review papers that collect the importance of stem cells as an alternative treatment to the DWH. We anticipate that the success of this treatment will have a significant clinical impact on diabetic wounds.

    Cytokines are extremely potent biomolecules that regulate cellular functions and play multiple roles in initiation and inhibition of disease. These highly specialised macromolecules are actively involved in control of cellular proliferation, apoptosis, cell migration and adhesion. This work, investigates the effect of transforming growth factor-beta2 (TGF-β2) on the biological regulation of chondrocyte and the repair of a created model wound on a multilayer culture system. Also the effect of this cytokine on cell length, proliferation, and cell adhesion has been investigated. Chondrocytes isolated from knee joint of rats and cultured at 4 layers. Each layer consisted of 2 × 105 cells/ml with and without TGF-β2. The expression of mRNA and protein levels of TGF-β receptors and Smad1, 3, 4, and 7 have been analysed by RT-PCR and western blot analysis. The effect of different supplementations in chondrocyte cell proliferation, cell length, adhesion, and wound repair was statistically analysed by One-way ANOVA test. Our results showed that the TGFβ2 regulates mRNA levels of its own receptors, and of Smad3 and Smad7. Also the TGF-β2 caused an increase in chondrocyte cell length, but decreased its proliferation rate and the wound healing process. TGF-β2 also decreased cell adhesion ability to the surface of the culture flask. Since, TGF-β2 increased the cell size, but showed negative effect on cell proliferation and adhesion of CHC, the effect of manipulated TGF-β2 with other growth factors and/or proteins needs to be investigated to finalize the utilization of this growth factor and design of scaffolding in treatment of different types of arthritis.

  13. Fulltext Improvement of diabetic wound healing by topical application of Vicenin-2 hydrocolloid film on Sprague Dawley rats
    Tan WS, Arulselvan P, Ng SF, Mat Taib CN, Sarian MN, Fakurazi S
    BMC Complement Altern Med, 2019 Jan 17;19(1):20.
    PMID: 30654793 DOI: 10.1186/s12906-018-2427-y
    BACKGROUND: Impaired wound healing is a debilitating complication of diabetes that leads to significant morbidity, particularly foot ulcers. The risk of developing diabetic foot ulcers for diabetic patients is 15% over their lifetime and approximately 85% of limb amputations is caused by non-healing ulcers. Unhealed, gangrenous wounds destroy the structural integrity of the skin, which acts as a protective barrier that prevents the invasion of external noxious agents into the body. Vicenin-2 (VCN-2) has been reported to contain prospective anti-oxidant and anti-inflammatory properties that enhance cell proliferation and migration. Sodium Alginate (SA) is a natural polysaccharide that possesses gel forming properties and has biodegradable and biocompatible characteristics. Therefore, the objective of this study is to evaluate the effect of SA wound dressings containing VCN-2 on diabetic wounds.

    METHODS: Wounds were inflicted in type-1 diabetic-streptozotocin (STZ) induced male Sprague Dawley rats. Subsequently, relevant groups were topically treated with the indicated concentrations (12.5, 25 and 50 μM) of VCN-2 hydrocolloid film over the study duration (14 days). The control group was treated with vehicle dressing (blank or allantoin). Wounded tissues and blood serum were collected on 0, 7 and 14 days prior to sacrifice. Appropriate wound assessments such as histological tests, nitric oxide assays, enzyme-linked immunosorbent assays (ELISA) and immunoblotting assays were conducted to confirm wound healing efficacy in the in vivo model. One-way Analysis of Variance (ANOVA) was used for statistical analysis.

    RESULTS: Results showed that hydrocolloid film was recapitulated with VCN-2 enhanced diabetic wound healing in a dose-dependent manner. VCN-2 reduced pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α), mediators (iNOS and COX-2), and nitric oxide (NO) via the NF-κB pathway. Data suggests that the VCN-2 film facilitated healing in hyperglycemic conditions by releasing growth factors such as (VEGF and TGF-β) to enhance cell proliferation, migration, and wound contraction via the VEGF and TGF-β mechanism pathways.

    CONCLUSIONS: This study's findings suggest that VCN-2 may possess wound healing potential since topical treatment with VCN-2 hydrocolloid films effectively enhanced wound healing in hyperglycemic conditions.

    Wound healing is a natural intricate cascade process involving cellular, biochemical and molecular mechanism to restore the injured or wounded tissue. Malaysia's multi-ethnic social fabric is reflected in its different traditional folk cuisines with different nutritional important ingredients. Despite these differences, there are some commonly used pantry ingredients among Malaysians and these ingredients may possess some healing power for acute and chronic wounds. These essential nutritional ingredients are included Amla (Ribes uva-crispa), Cinnamon (Cinnamomun venum), Curry Leaves (Murraya koenigii), Coriander (Coriandrum sativum), Fenugreek (Trigonella foenum-graecum), Garlic (Allium indica), Onion (Allium cepa) and Tamarind (Tamarindus indica). This article provides a review of the remedies with confirmed wound healing activities from previous experiments conducted by various researchers. Most of the researchers have focused only on the preliminary studies through appropriate model; hence detailed investigations which including pharmacological and pre-clinical studies are needed to discover its molecular mechanisms. In this review article, we have discussed about the wound healing potential of few commonly used edible plants and their known mechanism.

    PMID: 24490175 DOI: 10.1155/2013/974580
    Moringa oleifera Lam. (M. oleifera) from the monogeneric family Moringaceae is found in tropical and subtropical countries. The present study was aimed at exploring the in vitro wound healing potential of M. oleifera and identification of active compounds that may be responsible for its wound healing action. The study included cell viability, proliferation, and wound scratch test assays. Different solvent crude extracts were screened, and the most active crude extract was further subjected to differential bioguided fractionation. Fractions were also screened and most active aqueous fraction was finally obtained for further investigation. HPLC and LC-MS/MS analysis were used for identification and confirmation of bioactive compounds. The results of our study demonstrated that aqueous fraction of M. oleifera significantly enhanced proliferation and viability as well as migration of human dermal fibroblast (HDF) cells compared to the untreated control and other fractions. The HPLC and LC-MS/MS studies revealed kaempferol and quercetin compounds in the crude methanolic extract and a major bioactive compound Vicenin-2 was identified in the bioactive aqueous fraction which was confirmed with standard Vicenin-2 using HPLC and UV spectroscopic methods. These findings suggest that bioactive fraction of M. oleifera containing Vicenin-2 compound may enhance faster wound healing in vitro.

    Gelatin hydrogels are attractive for wound applications owing to their well-defined structural, physical, and chemical properties as well as good cell adhesion and biocompatibility. This study aimed to develop gelatin hydrogels incorporated with bio-nanosilver functionalized with lactoferrin (Ag-LTF) as a dual-antimicrobial action dressing, to be used in treating infected wounds. The hydrogels were cross-linked using genipin prior to loading with Ag-LTF and characterized for their physical and swelling properties, rheology, polymer and actives interactions, and in vitro release of the actives. The hydrogel's anti-biofilm and antibacterial performances against S. aureus and P. aeruginosa as well as their cytotoxicity effects were assessed in vitro, including primary wound healing gene expression of human dermal fibroblasts (HDFs). The formulated hydrogels showed adequate release of AgNPs and LTF, with promising antimicrobial effects against both bacterial strains. The Ag-LTF-loaded hydrogel did not significantly interfere with the normal cellular functions as no alteration was detected for cell viability, migration rate, and expression of the target genes, suggesting the nontoxicity of Ag-LTF as well as the hydrogels. In conclusion, Ag-LTF-loaded genipin-cross-linked gelatin hydrogel was successfully synthesized as a new approach for fighting biofilms in infected wounds, which may be applied to accelerate healing of chronic wounds.

    PMID: 10607016
    The effect of palm vitamin E on the healing of ethanol-induced gastric lesion was compared with ranitidine. Fifty-six male rats of Sprague-Dawley species (200-250 g of weight) were randomly divided into three groups (N = 14). Gastric mucosal injury was induced by orogastric tube administration of 0.5 ml 100% ethanol. Immediately after induction, Group I (k) rats was fed with a normal diet (control), group II (p) was fed palm vitamin E enriched diet (150 mg/kg food), Group III(r) was treated with ranitidine 30 mg/kg body weight intraperitoneally and Group IV (p + r) was fed with palm vitamin E and treated with ranitidine 30 mg/kg body weight intraperitoneally of the same dose. The rats were killed at the end of 1 week and 3 weeks of treatment or feeding. The rate of gastric healing was faster in palm vitamin E treated group compared to control and ranitidine treated groups as shown by a lower mean ulcer index. The effect was seen as early as the first week of treatment whereas ranitidine did not show any healing effect even after 3 weeks of therapy. Neither gastric acidity nor gastric mucus production are involved in gastroprotective effect of palm vitamin E. The most probable mechanism is via reducing lipid peroxidation process as shown by a significant decrease in gastric MDA.

  20. Stem cells conditioned medium: a new approach to skin wound healing management
    Jayaraman P, Nathan P, Vasanthan P, Musa S, Govindasamy V
    Cell Biol Int, 2013 Oct;37(10):1122-8.
    PMID: 23716460 DOI: 10.1002/cbin.10138
    Stem cell biology has gained remarkable interest in recent years, driven by the hope of finding cures for numerous diseases including skin wound healing through transplantation medicine. Initially upon transplantation, these cells home to and differentiate within the injured tissue into specialised cells. Contrariwise, it now appears that only a small percentage of transplanted cells integrate and survive in host tissues. Thus, the foremost mechanism by which stem cells participate in tissue repair seems to be related to their trophic factors. Indeed, stem cells provide the microenvironment with a wide range of growth factors, cytokines and chemokines, which can broadly defined as the stem cells secretome. In in vitro condition, these molecules can be traced from the conditioned medium or spent media harvested from cultured cells. Conditioned medium now serves as a new treatment modality in regenerative medicine and has shown a successful outcome in some diseases. With the emergence of this approach, we described the possibility of using stem cells conditioned medium as a novel and promising alternative to skin wound healing treatment. Numerous pre-clinical data have shown the possibility and efficacy of this treatment. Despite this, significant challenges need to be addressed before translating this technology to the bedside.
