Treatment Of Wounds

The treatment of wounds is one challenging biomedical field due to delayed wound healing common in chronic wounds. Several factors delay wound healing, including microbial infections, malnutrition, underlying physiological conditions, etc. Most of the currently used wound dressing materials suffer from poor antimicrobial properties, poor biodegradability and biocompatibility, and weak mechanical performance. Plant extracts, such as Aloe vera, have attracted significant attention in wound management because of their interesting biological properties. Aloe vera is composed of essential constituents beneficial for the wound healing process, such as amino acids, vitamins C and E, and zinc. Aloe vera influences numerous factors that are involved in wound healing and stimulates accelerated healing. This review reports the therapeutic outcomes of aloe vera extract-loaded polymer-based scaffolds in wound management.

Today, various commercial dressings have been developed and introduced to the market. The diversity makes it difficult for the nurse to choose the right type. Although the most important reason to use a wound dress is to protect the wound from infection and prevent infection, but in fact, the main purpose of using these materials is to speed up the wound healing process. Traumatic injuries result in an epithelial wound that disrupts the continuity of the skin surface. These differences reveal as abrasions, punctures, and injuries. Wounds are divided into two types; the skin is either cut or ruptured, including deep wounds and bruises, or surface wounds. Expedited wound healing has been considered since the archaic era of human civilization, with the earliest reported case from the Ancient Egyptians. Wound lesions in mummified humans were observed to be cover with animal skin, with signs of (primary/secondary) wound healing present. A "new wound dressing" is an advanced wound dress used in wound management as biocompatible and biodegradable biomaterials that heal wounds and burns. In the past, it was believed that dry wounds had expedited healing and wet wounds have been found to promote using re-epithelization and result in reduced scar formation. Wounds can be treated using various types of natural polymers and materials. Also, techniques like electrospinning and freeze-drying techniques can be used for the fabrication of standard wound dress. These wounds are associated with bandages, inflammation, bleeding, pain, and pus. In this work, we consider various types of wounds and techniques to treat the wound. Susceptibility to these areas, due to special symptoms for each of them. Products like hydrogels, hydrocolloids, films, sponges, and nano-fiber polymeric materials are used to promote healing. In this review, we examine the ideal products for the treatment of wounds in diabetic patients.

Healing Wounds

A wound is damage to the typical anatomic structure. Wound healing is an immediate therapeutic response to injury. It is a creation of the combined response of some cell types towards injury. Wound healing takes place by a sequence of molecular events which cooperate to fix tissue integrity and cell work. In typical healthy individual under ordinary conditions, these physiological events take place smoothly. Though sometimes, these molecular events are arrested, this brings about in struggle to heal. There is an assortment of approaches for the way toward managing and controlling both acute injuries (acute wounds) and ceaseless non-mending wounds (chronic non-healing wounds). The principal objective of these two cases is to achieve better-wound healing. Ideal formulations of wound healing should not only enhance the healing process but also reduce pain, infection and loss of electrolytes, proteins and liquids from the injury. A broad scope of items typically introduced with target various parts of the wound healing process depends on numerous types of wounds and novel polymers utilised for the conveyance of medications to both acute and ceaseless injuries. These include alginate, hydrocolloids, hydrofibers, polyurethane, and hydrogels. This article gives particular importance to different novel approaches in the management of wound healing. This review draws out the data and hopes to provide understanding into traditional, current and imminent techniques and methods for wound management.

Background: Treatment of wounds in diabetes often gets less than perfect healing. One of the reasons for the difficulty in treating wounds in diabetes is the growth of aerobic and anaerobic bacteria. This study aims to determine the pulse voltage and treatment time that can optimally inactivate bacteria, and their effect on wound healing in mice suffering from diabetes. Methods: The study used electrical stimulation with a direct voltage of 10 volts given a pulse voltage of 50-80 volts, a width of 50 µs, and the number of pulses of 65 per second. The research samples were Staphylococcus aureus (S. aureus) and Pseudo-monas aeruginosa (P. aeruginosa) bacteria that grew on beef and mice (Mus musculus) with diabetes. The treatment for S. aureus and P. aeruginosa bacteria was carried out using a pulse voltage of 50-80 volts for 5-15 min/day and repeated for 3 days. Meanwhile, treatment of mice wounds was carried out with a pulse voltage of 80 volts for 15 min/day and repeated for 7 days. Results: The results showed that treatment with a pulse voltage of 50-80 volts and a treatment time of 5-15 min significantly reduced the number of S. aureus and P. aeruginosa bacteria in beef (p£0.05). Treatment with a pulse voltage of 80 volts for 15 min made beef free from bacteria. Meanwhile, treatment with a pulse voltage of 80 volts for 15 min per day for seven days resulted in the wound state of three mice in the maturation phase and two mice in the proliferation phase on day 8 with an average wound area of 0.108 cm 2. Conclusion: The treatment with a pulse voltage of 80 volts for 15 min made the beef sterile, the mice wounds healed quickly, and the mice not stressed. The higher the blood glucose level, the slower the wound healing process.

Chronic wounds are a major health problem that cause millions of dollars in expenses every year. Among all the treatments used, active wound treatments such as enzymatic treatments represent a cheaper and specific option with a fast growth category in the market. In particular, bacterial and plant proteases have been employed due to their homology to human proteases, which drive the normal wound healing process. However, the use of these proteases has demonstrated results with low reproducibility. Therefore, alternative sources of proteases such as snake venom have been proposed. Here, we performed a functional mining of proteases from rattlesnakes (Crotalus ornatus, C. molossus nigrescens, C. scutulatus, and C. atrox) due to their high protease predominance and similarity to native proteases. To characterize Crotalus spp. Proteases, we performed different protease assays to measure and confirm the presence of metalloproteases and serine proteases, such as the universal protease assay and zymography, using several substrates such as gelatin, casein, hemoglobin, L-TAME, fibrinogen, and fibrin. We found that all our venom extracts degraded casein, gelatin, L-TAME, fibrinogen, and fibrin, but not hemoglobin. Crotalus ornatus and C. m. nigrescens extracts were the most proteolytic venoms among the samples. Particularly, C. ornatus predominantly possessed low molecular weight proteases (P-I metalloproteases). Our results demonstrated the presence of metalloproteases capable of degrading gelatin (a collagen derivative) and fibrin clots, whereas serine proteases were capable of degrading fibrinogen-generating fibrin clots, mimicking thrombin activity. Moreover, we demonstrated that Crotalus spp. are a valuable source of proteases that can aid chronic wound-healing treatments.

Skin regeneration after an injury is very vital, but this process can be impeded by several factors. Regenerative medicine is a developing biomedical field with the potential to decrease the need for an organ transplant. Wound management is challenging, particularly for chronic injuries, despite the availability of various types of wound dressing scaffolds in the market. Some of the wound dressings that are in clinical practice have various drawbacks such as poor antibacterial and antioxidant efficacy, poor mechanical properties, inability to absorb excess wound exudates, require frequent change of dressing and fails to offer a suitable moist environment to accelerate the wound healing process. Collagen is a biopolymer and a major constituent of the extracellular matrix (ECM), making it an interesting polymer for the development of wound dressings. Collagen-based nanofibers have demonstrated interesting properties that are advantageous both in the arena of skin regeneration and wound dressings, such as low antigenicity, good biocompatibility, hemostatic properties, capability to promote cellular proliferation and adhesion, and non-toxicity. Hence, this review will discuss the outcomes of collagen-based nanofibers reported from the series of preclinical trials of skin regeneration and wound healing.
