Burn Wound Healing

Treatment of non-healing burn injuries is a major challenge for the current scientific research. Hydrogen sulfide (H2S) is an endogenous gasotransmitter, which regulates redox homeostasis and cytoprotection during pathophysiological conditions. Similarly, heat shock proteins (HSPs) are molecular chaperones, which also confer cytoprotection during the wound repair process. Notably, the role of H2S as a regulator of HSPs during burn wound healing is still elusive. The present study investigated the effects of H2S supplementation on molecular chaperones during full-thickness, third-degree burn wound healing in the experimental rats. The animals were treated with sodium hydrosulphide (NaHS) as H2S donor (5 mg/kg body weight, intraperitoneal) daily for 10 days prior to burn-induction and continued till the fifth-day post-wounding. Histopathological analysis (Masson’s trichrome) revealed enhanced wound healing evident by increased collagen fiber deposition, cellular proliferation and re-epithelialisation in NaHS administered group as compared to the burn control. Furthermore, immunoblot analyses demonstrated significantly increased protein expression of molecular chaperons viz. HSP90, HSP70, HSP27, and GRP78 in H2S treated group as compared to control. Therefore, the present study signifies that H2S supplementation upregulates the protein expression levels of molecular chaperones, which could facilitate the cytoprotection during the tissue repair process and accelerates the burn wound healing.

Chitosan is recognized as a multipurpose biomaterial because of its low allergenicity, non-toxicity, biodegradability and biocompatibility. The present study was designed to estimate the role of chitosan derived from Lucilia cuprina on burn healing in diabetic mice; using histopathological and microbiological studies at different time intervals. Chitosan was prepared from L. cuprina with high molecular weight (MW) and high degree of deacetylation (DD) to evaluate its burn wound healing potential; skin burn closure assessment, histological and microbiological studies in vivo in male diabetic mice. Chitosan topical treatment was superior in wound closure acceleration; mainly in insulin injected group at all the time intervals. Additionally, earlier epidermal remodelling with mature and intense collagen deposition was encountered in all chitosan treated animals as well as non-diabetic burned animals. There was a significant delay in hair growth and poor epidermal remodelling with impairment of wound closure in diabetic groups. Moreover, chitosan treated groups assert the chitosan antibacterial effects with protecting the burn against contamination that hinders healing especially in this diabetic condition. Further researches needed to interpret effects of possible synergistic combination therapy.

Burn Wound Healing

Burn wound healing is a complex multifactorial process that relies on coordinated signaling molecules to succeed. Curcumin is believed to be a potent antioxidant and anti-inflammatory agent; therefore, it can prevent the prolonged presence of oxygen free radicals which is a significant factor causing inhabitation of optimum healing process. This study describes an extension of study about the biofunctional nanocomposite hydrogel platform that was prepared by using curcumin and an amphiphilic chitosan-g-pluronic copolymer specialized in burn wound healing application. This formular (nCur-CP, nanocomposite hydrogel) was a free-flowing sol at ambient temperature and instantly converted into a nonflowing gel at body temperature. In addition, the storage study determined the great stability level of nCur-CP in long time using UV-Vis and DLS. Morphology and distribution of nCur in its nanocomposite hydrogels were observed by SEM and TEM, respectively. In vitro studies suggested that nCur-CP exhibited well fibroblast proliferation and ability in antimicrobacteria. Furthermore, second- and third-degree burn wound models were employed to evaluate the in vivo wound healing activity of the nCur-CP. In the second-degree wound model, the nanocomposite hydrogel group showed a higher regenerated collagen density and thicker epidermis layer formation. In third degree, the nCur-CP group also exhibited enhancement of wound closure. Besides, in both models, the nanocomposite material-treated groups showed higher collagen content, better granulation, and higher wound maturity. Histopathologic examination also implied that the nanocomposite hydrogel based on nanocurcumin and chitosan could enhance burn wound repair. In conclusion, the biocompatible and injectable nanocomposite scaffold might have great potential to apply for wound healing.

Abstract: Theoretically, batata, Ipomea batata L (Lam) theoritically can be used in wound healing since it acts as antiseptic, antibiotic, and anti-inflammatory agents. Batata ingredients can also stimulate epithelialization in wound bed. This study aimed to obtain the role of batata juice in burn wound healing noticed from the inflammatory response aspect. This was an experimental study conducted in the research laboratory of Faculty of Medicine Univeristy of Sam Ratulangi. Samples were six rabbits divided into 2 groups: treatment group with batata juice, and control group without treatment. The histological examination showed that the quality of inflammatory tissue of the treatment group was denser, settled, and associated with edema expansion compared to the control group with diminished inflammatory components, edema, and vasodilatation, meanwhile, there were angiogenesis, improvement of dermis, and regrowth of epidermis. Conclusion: Batata juice was not superior in healing burns than the natural responses.Keywords: batata (Ipomeas batata L), burns, skin, inflammation, wound healingAbstrak: Batata, Ipomea batata L (Lam) secara teoritik berfaedah untuk penyembuhan luka, yang bekerja sebagai antiseptik, antibiotik, dan anti inflamatorik. Batata berkhasiat dalam penyembuhan luka karena kandungannya yang secara bermakna merangsang pembentukan epitel jaringan luka. Penelitian ini bertujuan untuk mendapatkan peran batata terhadap penyembuhan luka bakar dilihat dari kualitas komponen radang pada jaringan luka. Sampel terdiri dari 6 ekor kelinci yang dibagi atas 2 kelompok: kelompok perlakuan dan kontrol. Kelompok perlakuan diberi jus batata pada luka bakar sedangkan kelompok kontrol tanpa perlakuan. Penelitian ini dilakukan di Laboratorium Riset Fakultas Kedokteran Universitas Sam Ratulangi dengan menggunakan metode eksperimental. Hasil identifikasi mikroskopik menunjukkan bahwa pada kelompok perlakuan kualitas komponen radang jaringan luka bakar lebih padat dan menetap disertai perluasan sembab kolagen dibandingkan kelompok kontrol dimana komponen radang dan sembab berkurang, dilatasi pembuluh darah berkurang, pertumbuhan kapiler baru, jaringan dermis yang membaik, dan epidermis yang mulai tumbuh kembali. Simpulan: Jus batata tidak memperlihatkan penyembuhan luka bakar yang lebih baik dibandingkan dengan penyembuhan luka oleh tubuh sendiri.Kata kunci: batata (Ipomeas batata L), luka bakar, kulit, radang, penyembuhan luka

AbstractIn this work we use Mimosa tenuiflora (MtE) extracts as reducing agents to synthesize silver nanoparticles (AgMt NPs) which were characterized by DPPH and Total Polyphenols Assays, UV–visible, X-ray diffractometer (XRD), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and Thermogravimetric analysis (TGA). AgMt NPs possess average sizes of 21 nm and fcc crystalline structure, it was also confirmed that the MtE is present in the AgMt NPs even after the cleaning protocol applied. Subsequently, carbopol hydrogels were made and the MtE and the synthesized AgMt NPs were dispersed in different gels (MtE-G and AgMt NPs-G, respectively) at 100 µg/g concentration. The gels were characterized by UV–Vis, IR, and rheology. Antimicrobial tests were performed using Staphylococcus aureus and Escherichia coli. Burn wound healing was evaluated in a second-degree burn injury on a Wistar rats model for 14 days and additional skin biopsies were examined with histopathological analysis. Gel with commercial silver nanoparticles (Ag NPs) was prepared and employed as a control on the biological assays. Hydrogel system containing silver nanoparticles synthesized with Mimosa tenuiflora (AgMt NPs-G) is a promising therapeutic strategy for burn wound healing, this due to bactericidal and anti-inflammatory effects, which promotes a more effective recovery (in percentage terms) by damaged area.
