Abstract
BACKGROUND/AIMS Natural and synthetic biocompatible polymers have received significant attention in the pharmaceutical industry due to their rapid and effective healing properties in the wound healing process. The aim of this study was to optimize the extraction of onions, the preparation of sodium alginate/collagen/hydrogen boron nitride (NaAlg/Col/h-BN) membranes using the Box-Behnken experimental design, and determine the optimal conditions for quercetin release. The study also aimed to investigate the antimicrobial and antioxidant activities of the prepared membranes and their therapeutic properties. METHODS AND RESULTS The prepared membranes were characterized by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). Antimicrobial activities were tested against Gram-negative (Gr-) Escherichia coli ATCC 25922, Klebsiella pneumonia, Enterobacter aerogenes, Gram-positive (Gr+) Staphylococcus aureus ATCC 25923, and Candida albicans ATCC 10231 pathogens. In vitro release studies were conducted to examine the therapeutic properties of the prepared membranes. The optimum conditions for the extraction of onions and the preparation of NaAlg/Col/h-BN membranes were found to be EtOH = 75 mL, t = 2 h, T = 45°C, and NaAlg = 1.0 g, Col = 2.0 g, and h-BN = 6% wt, respectively. The prepared membranes exhibited serious antimicrobial properties against S. aureus and C. albicans. The membranes also promoted the controlled release of quercetin for 24 h in vitro, indicating their potential as a new approach in wound treatment. CONCLUSION The study concludes that quercetin-filled NaAlg/Col/h-BN membranes have promising therapeutic properties for wound healing. The membranes exhibited significant antimicrobial and antioxidant properties, and their controlled release of quercetin suggests their potential for use in wound healing applications.

Abstract
A non-healing wound is a common problem associated with diabetes mellitus. Chronic inflammation, challenging re-epithelization, unusual growth factors, and impaired angiogenesis are the multifactorial events that contribute to impaired wounds. Hence, in the present work, an innovative GA-CSNPs nanocomposite scaffold has been fabricated by integrating Gallic acid (GA) loaded chitosan nanoparticles (GA-CSNPs) into a genipin crosslinked collagen-fibrin (Col-fibrin) scaffold as wound dressing material. The in vitro RT-PCR study carried out using NIH/3T3 mouse fibroblast cells showed that treatment with GA-CSNPs nanocomposite scaffold aids in an upsurge in the expression of Col-I, III, and VEGF, which further supports the synthesis of extracellular matrix, increases neovascularization and development of the established vascular system. In vivo wound contraction study results revealed that diabetic wounds treated with GA-CSNPs nanocomposite scaffold show a faster rate of wound closure (p < .001), histopathology results showed accelerated fibroblast cell migration, reduction of the inflammatory cells, enhanced collagen along with hexosamine synthesis. In addition, immunohistochemistry results showed increased vascularization, a significant decrease in macrophage recruitment, and reduced expression of MMP-9 compared to the Col-fibrin scaffold and Control groups. Overall data suggest that the fabricated GA-CSNPs nanocomposite porous 3-D scaffold can be a hopeful therapeutic choice for diabetic wound management.

[PMID: 37251817 PMCID: PMC10209015 DOI: 10.1016/j.heliyon.2023.e16379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 04/27/2023] [Accepted: 05/15/2023] [Indexed: 05/31/2023] Open
Abstract
Onchocerciasis caused by Onchocerca volvulus Leuckart, 1893 is the second-world infection responsible for human blindness. Except Ivermectin which has as targets the microfilariae of that parasite, specific treatment for this disease does not exist and in developing countries, medicinal plants seem to remedy that health problem. For that, aqueous and hydro-ethanolic leaf, bark, and root extracts of Calotropis procera and Faidherbia albida were evaluated in vitro, against the most popular bovine model, Onchocerca ochengi and the free-resistant nematode Caenorhabditis elegans. O. ochengi microfilariae and adults extracted from the bovine nodules and skins as well as the free strains of C. elegans were exposed to the various concentrations of the plant parts extracts and Ivermectin. In results, all the plant parts extracts were rich in tannins, saponins, alkaloids, flavonoids, phenols, coumarins, and glycosides. Phenols (175.45 ± 0.01 mg EGA/g DM), flavonoids (158.98 ± 0.05 mg EC/g DM), and tannins (89.98 ± 2.56 mg ETA/g DM) contents were high in the bark hydro-ethanolic extract of F. albida. The leaf hydro-ethanolic extract of F. albida induced high activity against O. ochengi microfilariae (CL50 = 0.13 mg/mL). The bark hydro-ethanolic extract of F. albida was also the most effective on O. ochengi adults and particularly on female adults (CL50 = 0.18 mg/mL). Against the parasite strain resistant to Ivermectin, F. albida leaf hydro-ethanolic extract appeared more active with CL50 = 0.13 mg/mL. Similarly, the bark hydro-ethanolic extract of F. albida was the most potent on the wild strain of C. elegans. Thus, this study validates the use of these plants by traditional healers in the management of onchocerciasis and suggests a new source of isolation of the potential plant compounds against Onchocerca.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Skin diseases are among the most common human health affections. A healthy skin promotes a healthy body that can be achieved through modern, allopathic and natural medicines. Therefore, medicinal plants can be a reliable therapy in treating skin diseases in humans through a diverse range of bioactive molecules they contain. AIM OF THE STUDY This review aims to provide for the first-time scientific evidence related to the dermatological properties of Morocco's medicinal plants and it aims to provide a baseline for the discovery of new drugs having activities against skin issues. METHODS This review involved an investigation with different search engines for Moroccan ethnobotanical surveys published between 1991 and 2021. The plants used to treat skin diseases have been determined. Information regarding pharmacological effects, phytochemical, and clinical trials related to the plants listed in this review was collected from different scientific databases like PubMed, Science Direct, Google Scholar, Web of Science and Scopus. The data were analyzed and summarized in the review. RESULTS A total of 401 plants belonging to 86 families mainly represented by Asteraceae, Lamiaceae, Fabaceae, and Apiaceae which have been documented to be in common use by Moroccans for managing skin diseases. Among those plants recorded, the most commonly used are Allium cepa L, Chamaeleon gummifer (L.) Cass and Salvia rosmarinus Schleid. Mill. Leaves were the most commonly used plant part, while powder and decoction were the most common method of traditional drug preparation. 107 of the 401 plants (27%) have undergone pharmacological validation. A total of 44 compounds isolated from 27 plants were investigated to treat different types of skin diseases, and 25 plants have been clinically studied for their activities against skin diseases. CONCLUSION The beneficial effects of using Moroccan medicinal plants to treat skin diseases, according to traditional practices, have been proven in numerous scientific studies. Therefore, other studies should focus on isolating and identifying specific bioactive compounds from plant extracts, revealing more valuable therapeutic properties. Furthermore, additional reliable clinical trials are needed to confirm their beneficial effect on patients with skin diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The preparations of Phlomis aerial parts are used traditionally in Anatolia for wound healing and in inflammatory disorders. METHODS For the identification of the active fraction, the air dried aerial parts of Phlomis rigida Labill. were extracted by methanol and fractionated successively by n-hexane, dichloromethane and ethyl acetate, respectively. The phenolic constituents were characterized by the Folin-Ciocaltheu method; the antioxidant activity was performed by ABTS and DPPH radical scavenging assays. In vitro anti-inflammatory activity was evaluated by LOX enzyme inhibition, spectrophotometrically as well as cell cultures. The wound healing properties of P. rigida extract gels were studied via in vitro cell culture methods and in vivo by excisional wound model using Balb-c mice. The P. rigida extract was analyzed and characterized by GC-FID, GC-MS, and LC-MS. RESULTS The P. rigida methanol extract showed moderate LOX inhibitory at IC50 = 19.5 ± 2.8 μg/mL whereas the antioxidant activity was by DPPH• IC50 = 0.89 mg/mL, and by ABTS• IC50 = 0.99 mg/mL, respectively. In addition, a remarkable P. rigida extracts anti-inflammatory activity was observed in the cell culture assay, which was then confirmed by the in vitro wound healing activity applied at 0.125-0.5 mg/mL concentrations, resulting in a dose-dependent increase in wound closure at the final stage. The P. rigida gel formulation was prepared to evaluate the extract in vivo, whereas the experimental results of the new gel formulation supported the findings of the in vitro wound healing activity. CONCLUSION The findings of this in vitro and in vivo study suggest that the wound healing and anti-inflammatory properties provide a scientific evidence of the ethnopharmacological application of Phlomis species.

Abstract
The air-dried aerial parts of Phlomis russeliana (Sims) Lag. Ex Benth. was extracted by methanol and fractionated by n-hexane, dichloromethane, and ethyl acetate, respectively. The wound healing properties of P. russeliana extract gel was evaluated using the in vivo excisional wound model using Balb-c mice. Initially, the P. russeliana methanol extract showed LOX inhibitory activity at IC50 = 23.2 µg/mL, whereas the DPPH• assay showed IC50 = 0.89 mg/mL, and the ABTS• assay showed IC50 = 0.99 mg/mL, respectively. In addition, a remarkable anti-inflammatory activity was observed in the cell culture assay. Thereafter, activity-guided fractionation was performed by LOX enzyme inhibition assays, and the structures of the two most active fractions were revealed by both GC-FID and GC/MS analyses, simultaneously. Phytol and 1-heptadecanoic acid were characterized as the active constituents. Moreover, the P. russeliana extract gel formulation was applied for in vivo tests, where the new gel formulation supported the in vitro anti-inflammatory activity findings. As a conclusion, this experimental results support the wound healing evidence based on the ethnobotanical application of Phlomis species with further potential.

Tissue
engineering is currently one the fastest growing engineering
fields, requiring fabrication of advanced and multifunctional materials
to be used as scaffolds or dressing for tissue regeneration. In this
work, a bilayer matrix was fabricated by electrospinning of a hybrid
cellulose acetate nanofibers (CA) containing bioactive latex or Ciprofloxacin
over highly interconnected collagen (CSPG) 3D matrix previously obtained
by a freeze-drying process. The bilayer matrix was fabricated with
a nanofibrous part as the primary (top) layer and a spongy porous
part as the secondary (bottom) layer by combining electrospinning
and freeze-drying techniques to enhance the synergistic effect of
both materials corresponding to physical and biological properties.
The final material was physicochemically characterized using Fourier
transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The bilayer matrix exhibited
nanofibrous and 3D porous structure with properties such as high porosity,
swelling, and stability required for soft-tissue-engineering applications.
Furthermore, the in vitro biological and fluorescence
properties of the matrix were tested against NIH 3T3 fibroblast and
human keratinocyte (HaCaT) cell lines and showed good cell adhesion
and proliferation over the bilayer matrix. Thus, the synergistic combination
of nanofibrous material deposition onto to the collagenous porous
material has proved efficient in the fabrication of a bilayer matrix
for skin-tissue-engineering applications.

Abstract
ETHNO PHARMACOLOGICAL RELEVANCE Sida cordifolia is used commonly in traditional systems of medicine (TSM) and as folk remedies for treating the wounds (both external and internal), infected area, rheumatic disorders, muscular weakness, tuberculosis, heart problems, bronchitis, neurological problems etc. Therefore, in order to authenticate the claims, a mechanism-oriented investigation of the wound healing properties of this plant is essential. AIM OF THE STUDY The overall aim of the present research is to understand the precise unknown cellular and molecular mechanism by which S. cordifolia accelerates wound healing delay caused by the steroidal drug dexamethasone. Here, we have also tried to quantify intracellular superoxide with the help of a unique fluoroprobe MitoSOX based on fluorescence measurements in yeast MATERIALS AND METHODS: Wound healing property of successive extracts (ethyl acetate, methanol and aqueous) of S. cordifolia against dexamethasone-induced retardation of wound healing in rats was studied. The various extracts of S. cordifolia were characterised by determining the various phytochemicals and quantifying the total phenolic content and flavonoidal content by High throughput assays. In order to know the probable mechanism of action of the successive fractionates, assessed the antioxidant activity both by in-vitro (DPPH-assay) and in-vivo methods in wild-type Saccharomyces cerevisiae BY 4743 (WT) and knock-out strain (Δtrx2) against H2O2-induced stress mediated damages. The cell survival was evaluated after exposure to the oxidizing reagent (4 mM H2O2) by two methods which included the ability of cells to proliferate on solid or liquid medium. The cell membrane integrity/amount of mitochondrial ROS was determined by treating the strains with extract/standard in presence of H2O2 and propidium iodide (PI)/MitoSOX Red RESULTS: During the preliminary in-vivo wound healing study, the period for complete re-epithelialization of the wound tissue was reduced significantly (pin the treatment groups as compared to the negative control group. The formulation HF3 containing aqueous extract of S. cordifolia (SCA) showed highest wound healing potential against dexamethasone-retarded wounds in rats which justifies its traditional use. In the growth curve assay, the H2O2-induced growth arrest was restored by aqueous extract of S. cordifolia (SCA) in a concentration-dependent(pmanner both in the WT and Δtrx2 strains similar to the standard (ascorbic acid), H2O2 after 24 hours incubation which was also confirmed by the findings of CFU method. We got almost similar results of cell viability when stained with PI. The lower level of mitochondrial superoxide was indicated by a significant (preduction in the amount of MitoSOX stained cells, in the extract-treated group in contrast to the H2O2-stressed group. CONCLUSION It was concluded that HF3 can be applied topically in hydrogel form in the case of delayed wound healing caused by the steroidal drug-dexamethasone, aptly justifying its traditional use. Regarding its mechanism of action, our findings report that the potent adaptive response of SCA-treated WT and Δtrx2 strains towards intracellular ROS specifically mitochondrial-ROS confirms its antioxidant potential. Moreover, as SCA was able to rescue the Δtrx2 strains from stress, it can be inferred that it might be able to induce the enzyme thioredoxin-II to restore redox homeostasis. The findings with the conditional mutant ∆trx2 are the first proof linking SCA action related to particular cellular pathways which may be because of the phenols and flavonoids and their synergistic effect.

Abstract
OBJECTIVE Crinum jagus (J. Thomps.) Dandy commonly called Harmattan or St. Christopher's lily belonging to the family Liliaceae is widely used traditionally in Southeastern Nigeria for treatment of skin sores. This study investigated the wound healing potentials of methanolic C. jagus bulb extract (MCJBE) using incision, excision, and dead space wound healing models. MATERIALS AND METHODS Phytochemical screening showed the presence of alkaloids, glycosides, tannins, saponins in the extract, but absence of flavonoids. In the incision and dead space wound models, rats were dosed orally with 300 mg/kg body weight (bw) of 10 and 5% of MCJBE solution, respectively, while in the excision wound model, rats were treated topically with 10 and 5% MCJBE ointments (MCJBEO), respectively. RESULT The 10% MCJBE gave significantly (P < 0.05) highest percentage rate of wound contraction, shortest re-epithelialization and complete healing time when compared with 5% MCJBE and reference drug, framycetin sulfate. The extract of C. jagus showed significant (P < 0.05) concentration-dependent wound healing activity in incision, dead space and excision wound models. No contaminating microbial organism was isolated from wound sites of the rats dosed and treated with MCJBE throughout the study period. At day 7, post infliction of excision wound, histomorphological, and histochemical studies revealed more fibroblasts and Type 1 collagen deposits in wound site sections of rats treated with both 10 and 5% MCJBEO while those of the control showed more inflammatory cells and fewer Type 1 collagen deposits. At day 14 post infliction of excision wound, more epithelial regeneration with overlying keratin were seen in the histological sections of wounds of rats treated with both 10 and 5% MCJBEO, while histochemical study showed more Type 1 collagen deposits in wound site sections of rats in 10% MCJBEO treated group. CONCLUSION This study established that methanolic C. jagus bulb extract potentiates wound healing. The study thus validated the folkloric use of C. jagus bulb in the management of skin sores and boils.

Abstract
AIM The aim of this study was to evaluate the antimicrobial and antioxidant effects of Crinum jagus (J. Thomps.) Dandy methanolic bulb extract in wound healing. MATERIALS AND METHODS Phytochemical screening revealed the presence of alkaloids, glycosides, tannins, and saponins in the extract. In vitro antimicrobial activity of the extract was determined by agar well diffusion method. In vivo antimicrobial activity of the extract was determined by microbial assay of excision wound in rats contaminated with Staphylococcus aureus, Bacillus subtilis, Pseudomonas areuginosa, and Candida albicans and treated with 300 mg/kg body weight (bw) of 10 and 5% methanolic C. jagus bulb extract ointment (MCJBEO), respectively. Enzymatic antioxidant effect of the extract was determined in vivo by assaying superoxide dismutase (SOD) and catalase (CAT) activity, and malondialdehyde (MDA) level in excision wound biopsies of rats treated with 10 and 5% MCJBEO, respectively, following standard methods. Non-enzymatic antioxidant effect of the extract was determined in vitro using diphenylpicrylhydrazyl (DPPH) method following standard procedure. RESULTS The extract exhibited in vitro antimicrobial effect in a concentration-dependent manner with one hundred (100) mg/ml concentration of the extract having the highest inhibitory zone diameter for B. subtilis (25 mm), S. aureus (21 mm), and C. albicans (14 mm) followed by the 50, 25 and 12.5 mg/ml concentrations, respectively. B. subtilis, S. aureus, and C. albicans were not isolated from wounds of animals treated with both extract concentrations 10% and 5% MCJBEO, and reference drug (framycetin sulfate/clotrimazole). Activities of the enzymatic antioxidants SOD and CAT in wound biopsies treated with 10% MCJBEO were significantly (P < 0.05) higher when compared with those treated with 5% MCJBEO. Significantly (P < 0.05) decreased MDA level of wound biopsies from extract-treated rats was observed. The extract exhibited non-enzymatic antioxidant (DPPH) effect in a concentration-dependent manner. CONCLUSION This study has shown that an anti-microbial and antioxidant effects could possibly be part of mechanism by which C. jagus bulb extract promote wound healing process.
