Surface Contact

Burns injury is a global issue; when burns left unmonitored, it may lead to sepsis & hypovolemia. It majorly contributing to the country's morbidity and mortality. Accidental burns are quite common throughout the world. The degree of burns differs variably, and to identify a possible therapeutic option, it is of great importance for the researchers and scientists. Achieving a uniform burn wound model is thus required to study the burns injury at different levels involving epidermis, dermis, and hypodermis. The goal of this study is to create a simple third-degree contact burn in Wistar albino rats. Third-degree contact burn wound was monitored on 7th, 14th, and 21st day for natural wound healing under gross and histopathological observation. Gross observation reported damaged skin to appear dry, leathery, and charred. Wound closure was observed to be delayed and incomplete on day 21. Histopathology revealed a wound healing process by hematoxylin and eosin method. This metal surface contact method revealed a simplified and cost-effective method for inducing a third degree of a wound in Wistar rats. The study is thus a milestone that could enable research progress in the area of wound healing.

Stimulation Technique

High-voltage electrical stimulation has been long proposed as a method of accelerating the wound healing process. Its beneficial effect has been successfully evaluated in the treatment of a number of chronic ulcers and burns. We present here the implementation of a new wireless electrical stimulation technique for the treatment of a complicated chronic ulcer of the lower limb. The device is transferring charges to the wound, without any contact with it, creating a microcurrent that is able to generate the current of injury. The results suggest that this easy-to-use method is an effective therapeutic option for chronic ulcers.

Hydrogel Scaffolds

Tissue regeneration has become a promising strategy for repairing damaged skin tissues. Among the hydrogels for tissue regeneration applications, topical hydrogels have demonstrated great potential for use as 3D-scaffolds in the burn wound healing process. Currently, no report has been published specifically on icariin-loaded polyvinyl alcohol (PVA)/agar hydrogel on full-thickness burn wounds. In the present study, burn tissue regeneration based on biomimetic hydrogel scaffolds was used for repairing damaged extracellular matrix. Furthermore, a skin burn model was developed in rats, and the icariin-loaded PVA/agar hydrogels were implanted into the damaged portions. The regeneration of the damaged tissues with the help of the icariin-loaded hydrogel group exhibited new translucent skin tissues and repaired extracellular matrix, indicating that the hydrogel can enhance the wound healing process. Moreover, characterization studies such as X-ray diffraction, Fourier-transformed infrared spectroscopy, and differential scanning calorimetry reported the extent of compatibility between icariin and its polymers. Results of the field emission scanning electron microscopy images revealed the extent of the spread of icariin within the polymer-based hydrogel. Furthermore, the wound healing potential, confirmed by histopathological and histochemical findings at the end of 21 days, revealed the visual evidence for the biomimetic property of icariin-loaded PVA/agar hydrogel scaffolds with the extracellular matrix for tissue regeneration.

Diabetic Wound Healing

Introduction: The pleiotropic effects of statins are recently explored for wound healing through angiogenesis and lymph-angiogenesis that could be of great importance in diabetic wounds. Aim: Aim of the present study is to fabricate nanofilm embedded with simvastatin loaded chitosan nanoparticles (CS-SIM-NPs) has been reported herein to explore the efficacy of SIM in diabetic wound healing. Methods: The NPs, prepared via ionic gelation, were 173nm ± 2.645 in size with a zeta potential -0.299 ± 0.009 and PDI 0.051 ± 0.088 with excellent encapsulation efficiency (99.97%). The optimized formulation (CS: TPP, 1:1) that exhibited the highest drug release (91.64%) was incorporated into polymeric nanofilm (HPMC, Sodium alginate, PVA), followed by in vitro characterization. The optimized nanofilm was applied to the wound created on the back of diabetes-induced (with alloxan injection 120 mg/kg) albino rats. Results: The results showed significant (p < 0.05) improvement in the wound healing process compared to the diabetes-induced non-treated group. The results highlighted the importance of nanofilms loaded with SIM-NPs in diabetic wound healing through angiogenesis promotion at the wound site. Conclusion: Thus, CS-SIM-NPs loaded polymeric nanofilms could be an emerging diabetic wound healing agent in the industry of nanomedicines.

The aim of the study was to assess the propolis effect on fibronectin metabolism in the course of burn wounds healing process. A model of burn wound healing of pig skin was applied. The amount of the released glycoprotein was assessed by a surface plasmon resonance. The profile of extracted fibronectin components was also assessed by an electrophoresis in polyacrylamide gel, with a subsequent immunodetection by Western Blotting. Propolis burn treatment decreased the release of fibronectin components from healing wounds in relation to damages treated with silver sulfadiazine. The main reason of decreased extraction of fibronectin components from wounds treated with propolis was a substantial decrease of degradation product release of the mentioned glycoprotein, which was observed particularly from the 3rd to 5th day of the repair. Wounds treatment with propolis demonstrated, especially in relation to damages treated with silver sulfadiazine, the decreased release of synthesized fibronectin molecules. The obtained results suggest that propolis modifies fibronectin metabolism in the course of wound healing process. The influence of propolis is reflected in prevention of fibronectin biosynthesis as well as its degradation in the wound area. The above-mentioned metabolic changes may decrease the risk of complications in the repair wounds process.
