In Vivo Evaluation of Wound Healing Efficacy of Gel-Based Dressings Loaded with Pycnogenol™ and Ceratothoa oestroides Extracts. Gels 2024; 10:233. [PMID: 38667652 PMCID: PMC11048808 DOI: 10.3390/gels10040233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 03/25/2024] [Accepted: 03/26/2024] [Indexed: 04/28/2024] Open
Abstract
Ceratothoa oestroides and French maritime pine bark (Pycnogenol™) extracts are considered promising therapeutic agents in wound healing. This study explores the healing efficacy of composite dressings containing these extracts, aiming to enhance their stability and effectiveness, utilizing a low-temperature vacuum method for producing Sodium Alginate-Maltodextrin gel dressings. Surgical wounds were inflicted on SKH-hr2 hairless mice. Dressings were loaded with Pycnogenol™ and/or C. oestroides extracts and assessed for their efficacy. Wound healing was primarily evaluated by clinical and histopathological evaluation and secondarily by Antera 3D camera and biophysical measurements. Dressings were stable and did not compromise the therapeutic properties of C. oestroides extract. All interventions were compared to the C. oestroides ointment as a reference product. Most of the wounds treated with the reference formulation and the C. oestrodes dressing had already closed by the 15th day, with histological scores of 7 and 6.5, respectively. In contrast, wounds treated with Pycnogenol™, either alone or in combination with C. oestroides, did not close by the end of the experiment (16th day), with histological scores reaching 15 in both cases. Furthermore, treatment with 5% Pycnogenol™ dressing appeared to induce skin thickening and increase body temperature. The study underscores the wound healing potential of C. oestroides extracts and highlights the need for further research to optimize Pycnogenol™ dosing in topical applications.

Abstract
An effective strategy was employed for the rapid development of a supramolecular metallohydrogel of Mg(II) ion (i.e., Mg@PEHA) using pentaethylenehexamine (PEHA) as a low-molecular-weight gelator in aqueous medium under ambient conditions. The mechanical stability of the synthesized Mg@PEHA metallohydrogel was characterized by using rheological analysis, which showed its robustness across different angular frequencies and oscillator stress levels. The metallohydrogel exhibited excellent thixotropic behavior, which signifies that Mg@PEHA has a self-healing nature. Field emission scanning electron microscopy and transmission electron microscopy images were utilized to explore the rectangular pebble-like hierarchical network of the Mg@PEHA metallohydrogel. Elemental mapping through energy-dispersive X-ray spectroscopy analysis confirmed the presence of primary chemical constituents in the metallohydrogel. Fourier transform infrared spectroscopy spectroscopy provided insights into the possible formation strategy of the metallohydrogel. In this work, Schottky diode structures in a metal-semiconductor-metal geometry based on a magnesium(II) metallohydrogel (Mg@PEHA) were constructed, and the charge transport behavior was observed. Additionally, a resistive random access memory (RRAM) device was developed using Mg@PEHA, which displayed bipolar resistive switching behavior at room temperature. The researchers investigated the switching mechanism, which involved the formation or rupture of conduction filaments, to gain insights into the resistive switching process. The RRAM device demonstrated excellent performance with a high ON/OFF ratio of approximately 100 and remarkable endurance of over 5000 switching cycles. RRAM devices exhibit good endurance, meaning they can endure a large number of read and write cycles without significant degradation in performance. RRAM devices have shown promising reliability in terms of long-term performance and stability, making them suitable for critical applications that require reliable memory solutions. Significant inhibitory activity against the drug-resistant Klebsiella pneumonia strain and its biofilm formation ability was demonstrated by Mg@PEHA. The minimum inhibitory concentration value of the metallohydrogel was determined to be 3 mg/mL when it was dissolved in 1% DMSO. To study the antibiofilm activity, an MTT assay was performed, revealing that biofilm inhibition (60%) commenced at 1 mg/mL of Mg@PEHA when dissolved in 1% DMSO. Moreover, in the mouse excisional wound model, Mg@PEHA played a crucial role in preventing postoperative wound infections and promoting wound healing.

Abstract
This review summarizes the four processes of wound healing in the human body (hemostasis, inflammatory, proliferation, and remodeling) and the most current research on the most important factors affecting cutaneous wound healing and the underlying cellular and/or molecular pathways. Local factors, including temperature, oxygenation, and infection, and systemic factors, such as age, diabetes, sex hormones, genetic components, autoimmune diseases, psychological stress, smoking and obesity are also addressed. A better understanding of the role of these factors in wound repair could result in the development of therapeutics that promote wound healing and resolve affected wounds. Additionally, natural products obtained from plants and animals are critical targets for the discovery of novel biologically significant pharmacophores, such as medicines and agrochemicals. This review outlines the most recent advances in naturally derived targeted treatment for wound healing. These are plant-derived natural products, insect-derived natural products, marine-derived natural products, nanomaterial-based wound-healing therapeutics (metal- and non-metal-based nanoparticles), and natural product-based nanomedicine to improve the future direction of wound healing. Natural products extracted from plants and animals have advanced significantly, particularly in the treatment of wound healing. As a result, the isolation and extraction of bioactive compounds from a variety of sources can continue to advance our understanding of wound healing. Undescribed bioactive compounds or unexplored formulations that could have a role in today's medicinal arsenal may be contained in the abundance of natural products and natural product derivatives.

Abstract
92 cases of second degree burn wounds treated in our hospital from January 2019 to December 2019 were selected as the research objects, and the clinical effect of eCASH concept treatment combined with nano silver dressing on the second degree burn wounds was studied. The patients were
randomly divided into control group (n = 46) and observation group (n = 46). The control group was treated with conventional treatment combined with eCASH concept nursing, and the observation group was treated with eCASH concept combined with nano silver dressing. We found that
the effective rate of the observation group was 95.65% higher than that of the control group (76.09%); the wound healing time of the observation group was significantly lower than that of the control group; the average VAS pain score of the observation group during wound treatment was significantly
lower than that of the control group The total positive rate of bacterial detection in the observation group was 8.70%, which was lower than 28.26% in the control group; the incidence of complications in the observation group was 2.17% lower than that in the control group (17.39%); the differences
were statistically significant (all P < 0.05). These results indicate that eCASH concept combined with nano silver dressing in the treatment of second degree burn wounds has a significant effect, which can accelerate the recovery, reduce the pain, and effectively reduce the total
positive rate of bacterial detection and the incidence of complications.

Abstract
AbstractBackgroundIn hyperglycemic conditions like diabetes, impaired wound healing occurs due to endothelial damage, dysfunction of leukocyte, decreased phagocytosis and secondary infection which may lead to amputation and debility. Ethnomedicinally,Pteris vittataL. (PV) is used for wound healing. This fern is arsenic hyper-accumulator but its therapeutic aspect is still unexplored. Hence, the present study was put forth to study its aqueous extract and ethanolic extract in diabetic wound healing.MethodsRats were divided into diabetic control, povidine iodine (PI) treated, ethanolic and aqueous extracts of PV treated groups (n = 6). Circular excision wound closure was observed for 15 days with and without treatment. After study completion, skin was divided into four sections wherein first section was homogenized for collagen, hydroxyproline and hexosamine assay. Second, third and fourth sections were used for antioxidant assay, gene expression and histopathology. Column purified fraction of ethanolic extract of PV was subjected to High Performance Liquid Chromatography, Fourier-transform infrared spectroscopy, Nuclear Magnetic Resonance and Mass spectroscopy. Data obtained were analyzed using one way analysis of variance and expressed as Mean ± SD.ResultsThe percentage difference in wound area of day 15 to day 0 showed 65% wound contraction in diabetic control rats. The percentage reduction in wound area showed by PI and extracts of PV were 79% and 85% respectively. Statistical significant increase in collagen, hydroxyproline and hexosamine was observed in the test groups as compared to disease control and PI treated rats. Similarly, statistical significant increases in antioxidant enzymes were observed in the treated groups with decrease in lipid peroxidation. Treatment of rats with PI and two extracts of PV up-regulated Matrix Metalloprotein-9, Collagenase-2 and VEGF-1 and down regulated Tumor Necrosis Factor- α and Interleukin-6. Histopathology in diabetic rats showed incomplete scab formation with haemorrhages which were absent in treated rats. Spectral data showed presence of polyphenolic compounds, fatty acids and ascorbic acid.ConclusionAlternative and complimentary management based on herbal biotherapy which can promote angiogenesis, increase collagen and lower the levels of reactive oxygen species are warranted for healing of wounds in hyperglycaemic conditions which were achieved by two extracts of PV.
