J Trop Med 2024; 2024:9576349. [PMID: 39345301 PMCID: PMC11427741 DOI: 10.1155/2024/9576349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 08/06/2024] [Accepted: 08/29/2024] [Indexed: 10/01/2024] Open
Abstract
Introduction The aerial part of Ludwigia octovalvis has been used traditionally in some parts of Asia for the management of wounds owing to the presence of phytochemicals such as tannins, flavonoids, and triterpenoids among others. The incidence of wounds, their associated complications, and the cost of wound care are on the increase globally, therefore, the need to develop alternative wound care agents. The aim of this study was to scientifically investigate the wound healing potential of the ethanolic extract of L. octovalvis using the excision wound healing model in rats and also carry out an acute dermal toxicity investigation of the plant extract. Method A 70% ethanol extract of L. octovalvis was prepared for the wound healing activity using the excision wound healing model in Sprague-Dawley rats. Aqueous creams (1, 3, and 10%) were prepared and topically applied to the wounds once daily according to the groups of animals. The wounds were assessed for rates of wound closure on days 3, 5, 7, 9, and 11. Re-epithelialization periods were also determined. Sections of wound tissues obtained on day 13 were subjected to histological investigations. An acute dermal toxicity of the plant extract was investigated. Results L. octovalvis treatment (1, 3, and 10%) exhibited a mean percentage wound contraction range of 85.36 ± 7.22-94.14 ± 2.23 on day 11. The extract exhibited re-epithelialization periods of 17.3 ± 1.2, 19.8 ± 2.6, and 16.0 ± 1.7 days for the 1, 3, and 10% extract creams, respectively, whereas the cream-only and 1% silver sulfadiazine treatments resulted in a re-epithelialization period of greater than 28 days. Histopathological investigation revealed enhanced fibroblast infiltration and collagen deposition in the treatment groups. No adverse reaction was observed in the acute dermal toxicity study. Conclusions Extract of L. octovalvis exhibited wound healing by enhancing wound contraction, re-epithelialization, fibroblast infiltration, and collagen deposition at the wound site. The extract did not exhibit any toxic reaction in the acute dermal toxicity study.

Abstract
Curcuma longa L. and Plumbago zeylanica L. are renowned for their antioxidant, anti-inflammatory, and wound-healing properties, primarily attributed to their polyphenolic compounds. However, the limited water solubility of these compounds poses challenges to their effective utilization. Encapsulation within phytosomes offers a solution by enhancing bioavailability and permeability. This study aimed to formulate a phytosome-based polyherbal gel incorporating methanolic extracts of P. zeylanica and C. longa to explore its potential in wound healing. Methanolic extracts of P. zeylanica roots and C. longa rhizomes were encapsulated in phytosomes using the lipid film hydration technique. Various phytosome formulations were developed and characterized for encapsulation efficiency, particle size, polydispersity index and zeta potential. The optimized phytosomal dispersion (F7) was integrated into a carbopol-based hydrogel matrix. In vitro release studies demonstrated prolonged release compared to conventional forms. Stability testing confirmed the robustness of the phytosomal gel at 4 °C/60 ± 5% RH. Wound healing activity was assessed using an excision wound model. The phytosomal gel exhibited enhanced wound contraction and reduced epithelization time compared to conventional gel and control groups, signifying its potent wound-healing effect. In conclusion, the polyherbal phytosomal gel, incorporating P. zeylanica and C. longa, holds promise in promoting wound healing, presenting a novel and effective approach in the realm of topical formulations for wound care.

Abstract
BACKGROUND Tabernaemontana divaricata (TD) from the Apocynaceae family exhibits traditional therapeutic properties such as anti-inflammatory, antioxidant, and acetylcholinesterase activity, etc. OBJECTIVE: To formulate and evaluate the wound healing potential of standardized ethanolic extract of TD leaves hydrogel on experimental models of wounds in Wistar rats with the design of experiment approach. METHODS The prepared PVA-based hydrogel of TD extract was evaluated. In-vivo, wound healing activities using excision, incision, and burn wound models were performed concerning percent wound contraction, epithelialization period, tensile strength, and histological analysis. RESULTS On the 20th day of the excision model, percentage wound contraction for 0.5 mg/ml and 1 mg/ml extract hydrogel was found to be 90.35 % ± 0.46 and 97.28 % ± 0.59, respectively, while on the 9th day of incision model, the tensile strength of both doses of hydrogel was found to be 191.16 ± 1.51 g and 201.00 ± 1.29 g, respectively, indicating that both concentrations of the hydrogel showed significant (P < 0.05) wound healing as compared to disease control and vehicle control group. The histopathological study of hydrogel showed no necrotic cells and a greater amount of collagen. Furthermore, in the burn wound model, both doses of TD hydrogel had significant wound-healing activity, as demonstrated by a reduction in the time needed for epithelialization and an increase in the rate of wound contraction (P < 0.05). CONCLUSION The proposed formulation showed potential for wound healing and may be studied further in clinical trials.

Abstract
Current investigation deals with the gel formulation of purified polyphenol loaded nanoparticles for enhanced wound healing. Polyphenols purified using column chromatography an were characterized using HPLC in fractions. Silver nanoparticles were characterization using SEM, AFM, TEM, DLS. Cytotoxic effect was checked on L929 (Mouse fibroblast cells). Bioactive loaded nanoparticles were formulated in gel and subjected for physical characterization. Excision wound wistar rat models were established to measure the wound contraction measurement, histopathological studies, and biochemical assays. Docking and Simulation studies were performed to check the binding and stability with receptors progressing the chronic wound. From the column chromatography, B fraction has shown the presence of maximum polyphenolic content and as well as the polyphenol compounds such as quercetin, rutin and tannic acid as confirmed by the HPLC. Synthesize B fraction-AgNP were found to be below 100 nm in size and spherical in shape as per the characterization. No cytotoxic effect was observed on L929 cells treated with B fraction and its nanoparticles. Formulated B fraction-AgNP gel has revealed the better stability and earlier wound contraction, i.e. before the completion of 14 days of topical treatment. Histopathology studies and collagen content has confirmed the re-epithelization in skin wounds. MD simulation revealed the stability with PI3K and AKT. This can be concluded that tobacco stem polyphenol loaded nanoparticles has potent wound healing activity that can be utilized as nano-drug delivery system for suppression of chronic wound development.Communicated by Ramaswamy H.

Abstract
Wound healing, particularly for difficult-to-treat wounds, presents a serious threat and may lead to complications. Currently available dressings lack mucoadhesion, safety, efficacy, and, most importantly, patient compliance. Herein, we developed a unique, simple, and inexpensive injectable chitosan-methoxy polyethylene glycol (chitosan-mPEG) hybrid hydrogel with tunable physicochemical and mechanical properties for wound healing. The detailed physicochemical and rheological characterization of the chitosan-mPEG hydrogel has revealed chemical interaction between available -NH2 groups of chitosan and -COOH groups of mPEG acid, which, to our perspective, enhanced the mechanical and wound healing properties of hybrid chitosan and mPEG hydrogel compared to solo chitosan or PEG hydrogel. By introducing mPEG, the wound healing ability of hydrogel is synergistically improved due to its antibacterial feature, together with chitosan's innate role in hemostasis and wound closure. The detailed hemostasis and wound closure potential of the chitosan-mPEG hydrogel were investigated in a rat model, which confirmed a significant acceleration in wound healing and ultimately wound closure. In conclusion, the developed chitosan-mPEG hydrogel met all the required specifications and could be developed as a promising material for hemostasis, especially wound management, and as an excellent candidate for wound healing application.

Abstract
Panicum antidotale has traditionally been used as a poultice to alleviate local inflammation and painful diseases. This study aimed to evaluate the anti-inflammatory, wound-healing, analgesic, and antipyretic potential of its ethanol extract (PAAPEE) in vivo for the first time. In vitro antioxidant assays of Panicum antidotale using a 2,2-diphenyl-1-picrylhydrazyl assay revealed that it showed IC50 of 62.50 ± 6.85 μg/mL in contrast to standard, ascorbic acid, that showed IC50 of 85.51 ± 0.38 μg/mL. Administration of PAAPEE at a dose of 500 mg/kg (PAAPEE-500) displayed 78.44% and 75.13% inhibition of paw edema in carrageenen and histamine-induced edema models. respectively, 6 h post-treatment compared to that of the untreated group. Furthermore, it showed 68.78% inhibition of Freund's complete adjuvant-induced edema 21 days after treatment. It reduced the animal's rectal temperature in the yeast-induced fever model to 99.45 during the fourth h post-treatment. It significantly inhibited abnormal writhing by 44% in the acetic acid-induced pain model. PAE-500 also showed enhancement in wound closure by 72.52% with respect to that of the untreated group on the 10th day post-treatment using the excision healing of wound model. Histopathological examination of skin samples confirmed this improvement, showing enhanced tissue architecture with minimal infiltration of inflammatory cells. High-performance liquid chromatography (HPLC) of PAAPEE revealed the presence of quercetin, gallic, p-coumaric, benzoic, chlorogenic, syringic, ferulic, cinnamic, and sinapic acids. Molecular docking of 5-lipoxygenase and glycogen synthase kinase-3 β protein indicated their potential interaction within the active sites of both enzymes. Thus, P. antidotale serves as an effective natural wound-healing, anti-inflammatory, analgesic, and antipyretic agent.

Abstract
Purpose Prunus africana is a well-known plant that is used in Ethiopian traditional medicine for the treatment of wounds and other ailments, although there is no scientific evidence to back up the claims of its wound-healing properties. Thus, the objective of this study is to evaluate the wound-healing potential of P. africana bark extract in mice. Methods The bark of the plant was extracted by successive maceration using 80% methanol and then fractionated with aqueous, n-butanol, and chloroform. The crude extract and solvent fractions were formulated as an ointment. Wound healing activity was evaluated using excision and incision wound models. Total phenol, flavonoid, and alkaloid contents of the crude extract, aqueous, and n- butanol fractions of the plant were determined. Results In both models, mice treated with 5% (w/w) and 10% (w/w) crude extract ointment exhibited a significant (p < 0.001) wound healing activity compared with control as evidenced by the increased rate of wound contraction and hydroxyproline content, the reduced epithelialization time, and the higher skin breaking strength. Mice treated with aqueous fraction ointment exhibited a high percentage of wound healing effect among all solvent fractions. The aqueous fraction consisted of higher phenolic (49.71 ± 0.73 mg/g) and flavonoid (39.58 ± 0.27 mg/g) content, while alkaloid (3.89 ± 0.55 mg/g) content was the lowest. Conclusion Prunus africana stem bark extract demonstrated wound healing activity in mice model which supports the acclaimed use by Ethiopian traditional medicine.

Abstract
For centuries, communities have used medicinal plants to treat various diseases, such as Sansevieria trifasciata (Asparagaceae), for wound healing. However, a study on the wound-healing activity of this plant has not been conducted. Therefore, this study aimed to evaluate the hydrogel formulations of S. trifasciata extract (HESt) and its activity in wound healing. The HESt formulations were subjected to physical examination, pH measurement, spreading coefficient, rheological study, stability test, and wound-healing activity. Furthermore, the HPMC and carbopol 940 gel-forming agents were used to obtain this formulation. In the incision wound model, the experiment was divided into 5 groups, each consisting of 4 mice. Groups 1 and 2 served as a negative and positive control (octenidine gel), while 3, 4, and 5 were given HESt formulations of 15%, 20%, and 25% (w/w), respectively, for 15 days. Based on the wound healing activity test, HESt 20% and 25% (w/w) groups showed significant (p < 0.05) wound closure area on day 4 and from day 2 to 16. However, the HESt 15% (w/w) group showed no significant difference in wound-healing activity but had a higher closure than the negative control. Based on the evaluation of the hydrogel, all HESt formulations were reported to have fulfilled the standard requirements. The HESt formulations were also reported to be stable at various temperatures in the stability test. Therefore, S. trifasciata leaves extract has the potential to be developed as a wound-healing drug derived from herbal plants formulated into hydrogel preparations.

Abstract
OBJECTIVE In the present study, an attempt has been made to develop SL-loaded transfersomal gel for the effective treatment of delayed wound healing. SIGNIFICANCE The wound healing process consists of a complex series of biochemical events and changes in cellular activity that restore the integrity of the skin and the subcutaneous tissue. Sesamol (SL), which is a natural phenolic compound, is known for its antioxidant properties, anti-inflammatory properties, and wound-healing abilities. METHODS A thin-film hydration method was used to prepare SL-loaded transfersomes. Different formulations containing Tween-80 and Span-80 as edge activators were prepared and optimized. Various characteristics of vesicles were assessed, such as size, shape, loading efficiency, deformability, and in vitro skin penetration. The optimized formulation was then incorporated into 1% carbopol 940 gel. An in vivo wound healing potential of the selected formulation was assessed by an excision wound model. RESULTS The SL-loaded transfersomal gel displayed improved skin penetration and better skin deposition. Wound healing studies showed that the highest wound contraction was observed with SL-loaded transfersomes. Following 21 days of application of the transfersomal gel, a marked improvement in skin histological architecture was found. CONCLUSION The study findings suggest that transfersomal gel has great potential as a therapeutic option in wound healing.

Abstract
Objectives The study was aimed to formulate resveratrol (RSV) loaded microsponges to deliver drug at the wound site and incorporate it in the Moringa oleifera Lam. (Moringaceae) gel base to provide an appropriate moist environment for wound management. RSV, a stilbenoid that activates sirtuins and cell-signaling regulators involved in the process of wound healing. Materials and Methods Microsponges were prepared by oil in oil emulsion solvent diffusion method by optimizing the independent variables; drug: polymer ratio and volume of internal phase solvent and their effects on entrapment efficiency and particle size. Formulation batches were evaluated for drug content, production yield, entrapment efficiency, and in vitro drug release. The microsponges were further incorporated into M. oleifera gum gel, which was then evaluated for spreadability, viscosity, ex vivo diffusion study and in vivo studies using an excision wound model in rats. Results Scanning electron microscopy revealed spherical and porous nature of the microsponges in vitro-release study of the optimized batch of RSV microsponges showed 80.88% drug release within 8 h. Differential scanning calorimetry results revealed no drug and polymer interaction during the formation of microsponges. An ex vivo diffusion study through goat skin revealed sustained release of RSV through porous microsponges embedded in the gel base at the wound site. An in vivo study performed using an excision wound model showed wound healing and closure within day 8. Histopathology showed increased re-epithelization and reduced ulceration in RSV microsponge gel-treated group compared with sham operated. Conclusion RSV microsponge gel delivered the drug at the wound site and the gel base provided a moist environment and influenced cell adhesion, thereby promoting faster wound healing.

Abstract
INTRODUCTION The solvent fractions of the fruits of Argemone mexicana L. (Papaveraceae) have not yet been explored scientifically for in vivo wound healing and anti-inflammatory activities. The objective of this study was, therefore, to evaluate in vivo wound healing and anti-inflammatory activities of the solvent fractions of the fruit of Argemone mexicana L. (Papaveraceae) in rats. METHOD The crude extract of Argemone mexicana was fractionated with n-hexane, ethyl acetate, and distilled water. Wound healing activity was evaluated using excision and incision wound models while anti-inflammatory activity was evaluated using carrageenan-induced rat paw and cotton pellet-induced granuloma models. The fractions were evaluated at 5 and 10% ointments using moist-exposed burn ointment as the standard drug, and 100, 200, and 400 mg/kg test doses using aspirin, and dexamethasone as standard drugs for wound healing and anti-inflammatory activities, respectively. All treatment administrations were made orally for anti-inflammatory activity and applied topically for wound healing activity. RESULT The 10% w/w ethyl acetate fraction ointment showed a significant percentage of wound contraction, reduced period of epithelialization, increased amount of fibrosis, neovascularization, and collagen tissue formation (p < 0.01). The ethyl acetate fraction also showed a significant increase in tensile strength (55%; p < 0.01) and (81.10%; p < 0.01) at the tested doses of 5 and 10% w/w ointments, which was comparable to moist-exposed burn ointment. The ethyl acetate fraction also revealed a significant percent edema inhibition (61.41%; p < 0.01), suppression of the exudate (38.09% p < 0.01), and granuloma mass formations (53.47% p < 0.01) at the tested dose of 400 mg/kg. CONCLUSION The results of this study showed that the Ethyl acetate fraction of Argemone mexicana fruit has significant wound healing and anti-inflammatory activities which support the traditional claims of the experimental plant.

Abstract
The objective of the study was to evaluate the quality of Zamzam water, holy water for Muslims and consumed for its medicinal value. The present study demonstrates the physicochemical characterization and wound healing property of Zamzam water. The physicochemical characterization of Zamzam water samples was analyzed for dissolved oxygen, pH, conductivity, total dissolved solids, redox potential, zeta potential, polydispersity index, and zeta size. The microbial quality of Zamzam water was also assessed by exposing water samples to open air. In this work, Zamzam water was also screened for the medicinal value through wound healing properties in Wistar rats. Zamzam water exhibited a unique physicochemical characterization with high levels of dissolved oxygen, zeta potential, polydispersity index, redox potential, total dissolved solids, and conductivity before exposure to open air. After open air exposure, Zamzam water resisted the growth of bacteria. The wound healing properties of Zamzam water in vivo showed a 96% of healing effect on 12th day observation. The wound healing was achieved by modulating pro-inflammatory cytokine such as interleukin -1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor -α (TNF-α). Followed by the level of apoptosis markers caspase-9 and caspase-3 were reduced. The present study proved that Zamzam water is a good-quality water and showed excellent wound healing property. Therefore, Zamzam water can be used for pharmaceutical formulations.

Abstract
Wounds are a consequence of disruption in the structure, integrity, or function of the skin or tissue. Once a wound is formed following mechanical or chemical damage, the process of wound healing is initiated, which involves a series of chemical signaling and cellular mechanisms that lead to regeneration and/or repair. Disruption in the healing process may result in complications; therefore, interventions to accelerate wound healing are essential. In addition to mechanical support provided by sutures and traditional wound dressings, therapeutic agents play a major role in accelerating wound healing. The medicines known to improve the rate and extent of wound healing include antibacterial, anti-inflammatory, and proliferation enhancing agents. Nonetheless, the development of these agents into eluting nanofibers presents the possibility of fabricating wound dressings and sutures that provide mechanical support with the added advantage of local delivery of therapeutic agents to the site of injury. Herein, the process of wound healing, complications of wound healing, and current practices in wound healing acceleration are highlighted. Furthermore, the potential role of drug-eluting nanofibers in wound management is discussed, and lastly, the economic implications of wounds as well as future perspectives in applying fiber electrospinning in the design of wound dressings and sutures are considered and reported.

Abstract
The Solanaceae family is considered one of the most important families among plant species because, on one hand encompasses many staple food crops of the human diet while, on the other hand, it includes species rich in powerful secondary metabolites that could be valorized in medicine or drug formulation as well as nutraceuticals and food supplements. The main genera are Solanum, Capsicum, Physalis, and Lycium which comprise several important cultivated crops (e.g., tomato, pepper, eggplant, tomatillo, and goji berry), as well as genera notable for species with several pharmaceutical properties (e.g., Datura, Nicotiana, Atropa, Mandragora, etc.). This chapter discusses the nutritional value of the most important Solanaceae species commonly used for their edible fruit, as well as those used in the development of functional foods, food supplements, and nutraceuticals due to their bioactive constituents. The toxic and poisonous effects are also discussed aiming to highlight possible detrimental consequences due to irrational use. Finally, considering the high amount of waste and by-products generated through the value chain of the main crops, the sustainable management practices implemented so far are presented with the aim to increase the added-value of these crops.

Abstract
AIM The aim of the study was to assess the toxicity profile of Selaginella bryopteris extract and evaluate its wound healing activity. METHODS In vitro wound healing activity of S. bryopteris extract (5% and 10%) was performed using Clonogenic and Scratch assays. The toxicity profile of S. bryopteris extract ointment was evaluated on animals using acute toxicity and dermal toxicity tests. In vivo wound healing activity of S. bryopteris extract ointment (5% and 10%) was used to determine tensile strength in the incision wound healing model. RESULTS Results exhibited that the extract was safe up to 2000 mg/kg per oral dose and non-reactive while applied topically. In vitro results showed that S. bryopteris extract closed the wound gap created by 97.13% in 48 h. The clonogenic assay revealed that the surviving factor for HaCaT cells and MEF cells was 0.78 and 0.85 after treated with 10% concentrations of S. bryopteris. The tensile strength exhibited by S. bryopteris 5% and 10% groups was 395.4 g and 558.5 g in comparison to the control group. CONCLUSION Thus, S. bryopteris extract can be used as an alternative safe drug therapy against topical wounds.

Abstract
The objective of this study was to develop nanobiomaterial containing silver nanoparticles (AgNPs) for wound healing. AgNPs were synthesized using Saussurea lappa (Sl) aqueous root extract as reducing agent and were characterized physico-chemically using UV-vis spectral studies, XRD, FESEM, TEM, FTIR spectral analysis, DLS, and TG-DSC. Sl AgNPs production was optimized using response surface methodology. The cytotoxicity of Sl AgNPs was assessed by THP1 cell lines, which showed that Sl AgNPs were nontoxic with an IC50 of 151.10 μg/mL at 24 h. For topical application, Sl AgNPs was loaded on chitosan hydrogel was characterized through spreadability, in vitro release, antibacterial activity, swelling behavior, and SEM analysis. The chitosan Sl AgNPs hydrogel was subjected acute dermal toxicity test using Wistar albino rats and was found to be nontoxic. The excisional wound model was created along with Pseudomonas aeruginosa as an inoculant in Wistar albino rats. The chitosan Sl AgNPs hydrogel treated rats showed excellent wound healing qualities, lower bacterial counts, and enhanced production of connective tissues. Our findings strongly suggest that AgNPs synthesized from Saussurea lappa root extract loaded on chitosan hydrogel possibly applied for the remedy of infectious wounds at a concentration of 0.1 mg of Sl AgNPs/g of hydrogel.

Abstract
Hydrogels being a drug delivery system has great significance particularly for topical application in cutaneous open wound. Its specific physicochemical properties such as non-adhesiveness, moisture retention, exudate absorption, and gas permeability make them ideal as a drug delivery vehicle for wound healing application. Further, curcumin (a natural bioactive) was selected as a therapeutic agent to incorporate into the hydrogel system to design and develop nanogel pharmaceutical products for wound healing. Although, curcumin possesses remarkable anti-inflammatory, antioxidant, and anti-infective activity along with hastening the healing process by acting over the different stages of the wound healing process, but its poor biopharmaceutical (low aqueous solubility and skin penetrability) attributes hamper their therapeutic efficacy for skin applications. The current investigation aimed to develop the curcumin-loaded nanogel system and evaluated to check the improvement in the therapeutic efficacy of curcumin through a nanomedicine-based approach for wound healing activity in Wistar rats. The curcumin was enclosed inside the nanoemulsion system prepared through a high-energy ultrasonic emulsification technique at a minimum concentration of surfactant required to nanoemulsify the curcumin-loaded oil system (Labrafac PG) having droplet size 56.25 ± 0.69 nm with polydispersity index 0.05 ± 0.01 and negatively surface charge with zeta potential −20.26 ± 0.65 mV. It was observed that the impact of Smix (surfactant/co-surfactant mixture) ratio on droplet size of generated nanoemulsion is more pronounced at lower Smix concentration (25%) compared to the higher Smix concentration (30%). The optimized curcumin-loaded nanoemulsion was incorporated into a 0.5% Carbopol® 940 hydrogel system for topical application. The developed curcumin nanoemulgel exhibited thixotropic rheological behavior and a significant (p < 0.05) increase in skin penetrability characteristics compared to curcumin dispersed in conventional hydrogel system. The in vivo wound healing efficacy study and histological examination of healed tissue specimen further signify the role of the nanomedicine-based approach to improve the biopharmaceutical attributes of curcumin.

Lambebo MK, Kifle ZD, Gurji TB, Yesuf JS. Evaluation of Wound Healing Activity of Methanolic Crude Extract and Solvent Fractions of the Leaves of Vernonia auriculifera Hiern (Asteraceae) in Mice. J Exp Pharmacol 2021; 13:677-692. [PMID: 34326671 PMCID: PMC8315810 DOI: 10.2147/jep.s308303] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 06/01/2021] [Indexed: 11/23/2022] Open
Abstract
Background Medicinal plants play an important role in treating various diseases. Vernonia auriculifera Hiern is one of the medicinal plants used traditionally for the management of wounds. However, there were no scientific reports documented so far on the wound healing activities to substantiate the claim. Thus, the present study provides a scientific evaluation for the wound healing potential of the crude extract as well as solvent fractions of the leaves of Vernonia auriculifera Hiern. Methods Extraction was carried out by maceration using 80% methanol and part of the crude extract fractionated with chloroform, ethyl acetate, and aqueous solvents. Simple ointment bases were prepared using hard paraffin, cetostearyl alcohol, white soft paraffin and wool fat according to British Pharmacopoeia. Then, two types of ointment formulations were prepared from the extract, ie, 5% w/w and 10% w/w. Mice and rats were employed for wound healing study and dermal toxicity test, respectively. Wound healing effects were evaluated by percent of wound contraction, period of epithelialization, tensile strength, and histological analysis as parameters in excision, incision, and burn wound models. Finally, the data were expressed as mean ± SEM, and the results were analyzed using one-way ANOVA followed by post hoc Tukey-test. Results In the excision wound model, the 10% w/w crude extract ointment showed significant wound contraction (P < 0.001) from day 4 to day 18 as compared to the negative control. Both the 5% w/w (P < 0.001) and 10% w/w (P < 0.05) crude extract ointments have showed statistically significant difference in epithelialization period as compared to the negative control. Groups treated with the ethyl acetate and aqueous fractions ointments in incision wound model showed a statistically significant (P < 0.001) increase in tensile. The 10% w/w and 5% w/w ointments of the crude extract showed a significant (P < 0.001) increase in breaking strength compared to simple ointment and the untreated control groups. In burn wound model, significant reduction in epithelialization period was observed in 5% w/w (P < 0.05) and 10% w/w (P < 0.001), and the percentage of wound contraction was significantly increased in most of post wounding days by 10% w/w (P < 0.001) and 5% w/w (P < 0.05) crude extract ointments and compared to the negative control. Conclusion The crude, aqueous, and ethyl acetate fraction of Vernonia auriculifera leaves possess wound healing activities. This finding justifies the use of the leaves of this plant for wound healing as claimed in the traditional medicine literature.

Abstract
Abstract
Background
Alnus glutinosa (L) is a widespread medicinal plant on the territory of the Republic of Belarus. Alnus glutinosa (L) leaves tincture has an anti-inflammatory effect on the diseases of the throat, intestines, in rheumatism and gout. Water extracts from collective fruit, leaves and bark are used for gargling in stomatitis and gum bleeding. The purpose of the research was to establish wound healing activity of gels based on alcohol extracts from Alnus glutinosa (L) leaves on the model of a surface full flap skin wound on laboratory animals.
Methods
Regenerating action of new drugs (gels) based on tinctures of Alnus glutinosa (L) leaves was studied on a model of planar full-layer skin wound in laboratory animals. Wounds were treated daily with gels applied to complete healing. The wound area was measured planometrically to assess the effectiveness of drugs and then the percentage of area reduction was calculated. Regenerative action of the gels developed was compared to widely used in medical practice 4% Dexpanthenol Gel and Reparef-2 Ointment. 15 g of Reparef-2 Ointment contains 1200 mg of bien and 75 mg of dioxidine.
Results
Wound healing activity of gels containing tinctures of Alnus glutinosa (L) leaves based on 30% and 60% alcohol as to the rate of healing and the area of wounds epithelialization has been proved. Wound area treated with the gel based on Alnus glutinosa (L) extract containing 60% alcohol on day 13 of the experiment decreased by 95.59% ± 0.9% (p ≤ 0.05); based on the tincture containing 30% alcohol - by 92.93% ± 1.11%. Medicinal preparations with proved wound healing activity were compared: Reparef-2 Ointment (reduction percentage of wound area on day 13 of the experiment made 92.24% ± 2.21%) and Dexpanthenol Gel (reduction percentage of wound area on day 13 of the experiment made 83.09% ± 3.41%).
Compared with the control group the gel based on 60% tincture of Alnus glutinosa (L) leaves showed a decrease in the epithelialization period by 29.5%; based on 30% tincture - by 24.6%; Reparef-2 Ointment - by 23.6% and Dexpanthenol Gel - by 13.8%.
Conclusions
The results of this study showed that the developed gels based on Alnus glutinosa (L) have a regenerating action and can be used to treat wound processes taking into account previously established antimicrobial activity.

Abstract
Thymoquinone is a natural bioactive with significant therapeutic activity against multiple ailments including wound healing. The poor aqueous solubility and low skin permeability limit its therapeutic efficacy. The present investigation aimed to improve the biopharmaceutical attributes of thymoquinone to enhance its topical efficacy in wound healing. A nanoemulsion-based hydrogel system was designed and characterized as a nanotechnology-mediated drug delivery approach to improve the therapeutic efficacy of thymoquinone, utilizing a high-energy emulsification technique. The black seed oil, as a natural home of thymoquinone, was utilized to improve the drug loading capacity of the developed nanoemulsion system and reduced the oil droplet size to <100 nm through ultrasonication. The influence of formulation composition, and the ultrasonication process conditions, were investigated on the mean globule size and polydispersity index of the generated nanoemulsion. Irrespective of surfactant/co-surfactant ratio and % concentration of surfactant/co-surfactant mixture, the ultrasonication time had a significant (p < 0.05) influence on the mean droplet size and polydispersity index of the generated nanoemulsion. The developed nanoemulgel system of thymoquinone demonstrated the pseudoplastic behavior with thixotropic properties, and this behavior is desirable for topical application. The nanoemulgel system of thymoquinone exhibited significant enhancement (p < 0.05) in skin penetrability and deposition characteristics after topical administration compared to the conventional hydrogel system. The developed nanoemulgel system of thymoquinone exhibited quicker and early healing in wounded Wistar rats compared to the conventional hydrogel of thymoquinone, while showing comparable healing efficacy with respect to marketed silver sulfadiazine (1%) cream. Furthermore, histopathology analysis of animals treated with a developed formulation system demonstrated the formation of the thick epidermal layer, papillary dermis along with the presence of extensive and organized collagen fibers in newly healed tissues. The outcome of this investigation signifies that topical delivery of thymoquinone through nanoemulgel system is a promising candidate which accelerates the process of wound healing in preclinical study.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2021; 2021:6690965. [PMID: 34239592 PMCID: PMC8233086 DOI: 10.1155/2021/6690965] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 06/10/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Artemisia afra (Jacq. ex Willd.), commonly called African wormwood, is a highly aromatic perennial herb and a well-known medicinal plant, claimed to be effective and safe in the treatment of epilepsy. The whole-plant extract is traditionally used as an antiepileptic agent in Ethiopia. Aim of the Study. The aim of this study was, therefore, to evaluate the anticonvulsant effect of the hydroethanolic extract and solvent fractions of A. afra whole part in mice. MATERIALS AND METHODS The effects of A. afra hydroethanolic extract and its solvent fractions were evaluated against pentylenetetrazole- (PTZ-) induced convulsions in mice. The onset and duration of PTZ-induced convulsions were determined with hydroethanolic A. afra extract and its solvent fractions. Data were analyzed using a one-way analysis of variance (ANOVA) followed by post hoc Tukey's multiple comparisons test. p < 0.05 was considered statistically significant. RESULTS The hydroethanolic extract of A. afra, with all the three doses of 250, 500, and 1000 mg/kg, showed a significant delay (504.833 ± 62.835 ∗ s; p < 0.05 ∗ ; 551.833 ± 47.69 ∗∗ s; p < 0.01 ∗∗ ; and 808.333 ± 64.8 ∗∗∗ s; p < 0.001 ∗∗∗ , respectively) in the mean onset of convulsion and a decrease (17.000 ± 1.88 ∗∗∗ s, p < 0.05 ∗ ; 13.000 ± 1.8 ∗∗ s, p < 0.01 ∗∗ ; and 7.833 ± 1.07 ∗∗∗ s, p < 0.001, respectively) in the mean duration of convulsion against PTZ-induced convulsion in a dose-dependent manner compared to the control (92.833 ± 13.006 s; 34.167 ± 3.683 s), and its anticonvulsant activity was significantly less compared to that of diazepam (1001.167 ± 68.430 s; 4.500 ± 0.619 s). The solvent fractions, however, did not show anticonvulsant activity against PTZ-induced convulsion. CONCLUSION Crude extract of A. afra has an anticonvulsant effect in mice. This might be attributed to the synergistic effects of two or more active ingredients present in the herb.

Investigation of the Potential of Nebivolol Hydrochloride-Loaded Chitosomal Systems for Tissue Regeneration: In Vitro Characterization and In Vivo Assessment. Pharmaceutics 2021; 13:pharmaceutics13050700. [PMID: 34064916 PMCID: PMC8150897 DOI: 10.3390/pharmaceutics13050700] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 05/03/2021] [Accepted: 05/05/2021] [Indexed: 12/13/2022] Open
Abstract
In this study, we evaluated the synergistic effect of nebivolol hydrochloride (NVH), a third-generation beta-blocker and NO donor drug, and chitosan on the tissue regeneration. Ionic gelation method was selected for the preparation of NVH-loaded chitosomes using chitosan lactate and sodium tripolyphosphate. The effect of different formulation variables was studied using a full factorial design, and NVH entrapment efficiency percentages and particle size were selected as the responses. The chosen system demonstrated high entrapment efficiency (73.68 ± 3.61%), small particle size (404.05 ± 11.2 nm), and good zeta potential value (35.6 ± 0.25 mV). The best-achieved formula demonstrated spherical morphology in transmission electron microscopy and amorphization of the crystalline drug in differential scanning calorimetry and X-ray diffraction. Cell culture studies revealed a significantly higher proliferation of the fibroblasts in comparison with the drug suspensions and the blank formula. An in vivo study was conducted to compare the efficacy of the proposed formula on wound healing. The histopathological examination showed the superiority of NVH-loaded chitosomes on the wound proliferation and the non-significant difference in the collagen deposition after 15 days of the injury to that of intact skin. In conclusion, NVH-loaded chitosomes exhibited promising results in enhancing skin healing and tissue regeneration.

Abstract
INTRODUCTION The various fractions of leaves of Achyranthes aspera L. (A. aspera) have not yet been explored scientifically for in-vivo wound healing and anti-inflammatory activities. The objective of this study was, therefore, to evaluate in-vivo wound healing and anti-inflammatory activities of solvent fractions of 80% methanol leaf extract of A. aspera in rats. METHODS The 80% methanol leaf extract of A. aspera was fractionated with chloroform, n-butanol and water. Wound healing and anti-inflammatory activities were evaluated using excision and incision wound models, rat paw edema and cotton pellet-induced granuloma models, respectively. For wound healing activity, fractions were evaluated at 5 and 10% ointments. The positive control groups were treated with nitrofurazone 0.2% ointment. Simple ointment treated for excision wound model and untreated for incision wound model rats were assigned as negative controls. For anti-inflammatory activity, fractions were evaluated at 100, 200 and 400mg/kg. Positive control groups were treated with indomethacin 10mg/kg for both rat paw edema and cotton pellet-induced granuloma models. The 2% Tween 80 treated rats were assigned as negative controls for both anti-inflammatory activity models. All groups comprised of 6 rats and treatment administrations were made topically and orally for evaluation of wound healing and anti-inflammatory activities. RESULTS The 10% w/w chloroform fraction ointment revealed a high percentage of wound contraction and reduced period of epithelialization (p <0.01). Chloroform fraction was also found to be the most active fraction, which demonstrated the maximum percentage inhibition of edema (52.50%; p <0.01) and transudative and proliferative component of chronic inflammation (37.52 and 52.81%; p <0.01), which was comparable to indomethacin. CONCLUSION Data obtained from this study collectively indicated that a chloroform fraction of 80% methanol leaf extract of A. aspera possessed significant wound healing and anti-inflammatory activities.

Abstract
Background : Vitex pinnata is a popular ethnomedicinal plant but scientific studies to validate its pharmacological properties are lacking for this plant. This study aims to determine the antioxidant, antimicrobial and wound healing properties of the methanolic extract of the leaves and the hexane, chloroform and ethyl acetate fractions. Methods: The leaves of Vitex pinnata underwent methanol extraction and the methanol extract was fractionated with hexane, chloroform and ethyl acetate solvents. The antioxidant activity was determined using the DPPH radical scavenging assay. The antimicrobial activity was assessed by disc diffusion assay against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. For the wound healing studies, the methanolic extracts of V. pinnata were used to prepare ointments with compositions of 10% (w/w) and 50% (w/w), which were evaluated for wound healing activity in an excision wound model in Wistar rats. Results: All the extracts showed antioxidant activities, with the ethyl acetate extract having the highest DPPH radical scavenging activity, followed by the methanol, chloroform and hexane extracts. Similarly, their quercetin equivalent concentrations were 33.1, 31, 20.3 and 4.5 mg/mL, respectively. Except for the methanol extract, the disc diffusion assay showed that the extracts demonstrated species-specific antibacterial activities, with the ethyl acetate extract showing antibacterial activities against all four tested strains. The wound healing activity of the high dose treated group (50% [w/w]) shows significant increase of wound contraction when compared to the control group. Conclusion: In the current study, the ethyl acetate extract showed activity for all tested bacteria and also had the highest DPPH activity. The methanolic extracts of V. pinnata leaves show modest wound healing activity in an excision wound model.

Abstract
Here, we have studied the efficacy of pullulan gel on wound healing by performing biochemical, biophysical and histological investigations. A 2 cm2 open excision wound was made on the dorsum of the rats and topically treated with 500 μL of pullulan gel. The control group was left untreated. The povidone-iodine (PI) ointment treated animals were considered as positive control. The granulation tissues formed were collected at different time point intervals and used for various biochemical, biophysical and histological analyses. Biochemical analyses revealed that pullulan gel significantly (p < 0.001) improved the collagen, hexosamine, protein and DNA content. Biophysical analyses resulted in an increased rate of wound contraction (p < 0.001). The period of epithelialization was shorter (p < 0.001) in pullulan gel treated group (11 days) than control (22 days) and PI group (17 days). Histological evaluation on days 4, 8 and 11 substantiated that pullulan gel treatment improved the wound re-epithelialization, dermal regeneration, blood vessels formation and collagen synthesis than in control and PI groups. Interrupted SDS-PAGE of collagen showed an increase in Type III collagen band evident for the healing potential of pullulan gel. Thus, our results strongly prove that pullulan gel could be a potential wound healing agent.

Abstract
Boerhavia diffusa is a perennial herb belonging to the Nyctaginaceae family. This plant has been widely used in Indian traditional medicinal system to cure several human ailments. However, traditional use of this plant in the treatment and management of wounds has not been validated by any comprehensive scientific study. The present study was aimed to explore the in vitro and in vivo wound healing potential of methanol extract (ME) and chloroform extract (CE) from B. diffusa leaf and subsequent identification of the bioactive metabolites, which might be responsible for enhancement of wound healing property of the extracts. The study included in vitro cell viability and wound scratch assays as well as in vivo excision wound assays in rat models. Both ME and CE were analysed for their antioxidant properties and phenolics content. The gas chromatography-mass spectrometry analyses were performed for identification of bioactive metabolites present in the ME and CE. ME of B. diffusa leaf significantly enhanced viability and migration of human keratinocyte cells (HaCaT) as compared to the untreated and CE-treated groups. The topical application of ME of B. diffusa leaf in excision wound model significantly decreased the wound area by the 14th day (91%) as compared to control (22%) (p < 0.05). The GC-MS analysis revealed the presence of caffeic acid, ferulic acid and D-pinitol as the major bioactive metabolites in ME. These results suggest that ME of B. diffusa possesses significant wound healing potential, where D-pinitol and caffeic acid served as the lead constituent metabolites responsible for the healing. Reporting wound healing potential of Boerhavia diffusa leaf extracts. GC-MS analyses of B. diffusa leaf extracts to identify bioactive wound healing metabolites. D-Pinitol and caffeic acid were identified as lead metabolites triggering wound healing.

Abstract
Although alginate has been known to be a good wound dressing, it does not have antimicrobial properties, has low availability, and is expensive. To overcome these problems, the present study was conducted, where the extraction of this material from an available small factory Pseudomonas aeruginosa and the improvement of its wound healing property by its combination with herb extract, Alhagi maurorum, done. Nineteen P. aeruginosa strains were isolated and identified from burned skin, and the one isolated strain with the highest ability of alginate production was selected. A. maurorum aqueous extract was prepared, and the toxicity of each material was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5diphenyltetrazolium bromide assay. A mixture of nontoxic doses of each substance was then prepared. Thirty-two Wistar rats were divided into four groups (n = 8). The control group and the rest three groups, which were treated by alginate, A. maurorum extract, and alginate- A. maurorum extract. Throughout the 21 days of treatment, the open wound sites were checked. Finally, the rats were sacrificed and the effect of each substance on their skin tissue was evaluated. The results showed that the high alginate production without any toxic effect was obtained from the P. aeruginosa strain K1. A. maurorum aqueous extract had dose-dependent toxicity. The aqueous solution of alginate- A. maurorum extract complex group showed the best wound healing activity in both macroscopic and microscopic examinations. Recent research has introduced a new type of wound dressing with high wound healing properties. This could decrease the time for re-epithelialization and increase wound contraction percentage.

Abstract
Background Euphorbia hirta linn., is a species of Euphorbiaceae family. They are known as asthma plant, barokhervi. The plant E. hirta is famous for its medicinal importance among the tribal population. It is a common practice to use the whole to heal wounds. Several pharmacological properties including antiseptic, anti-inflammatory, antidibetic, antispasmodic, antibacterial, antiviral, antifungal, anticonvulsant, nootropic, antifertility and aphrodisiac properties have already been reported for this plant. The aim of present work was to evaluate the wound healing property in diabetic animals by oral and topical administration of ethanolic extract of E. hirta whole plant. Methods The ethanolic extract of E. hirta was subjected to determine the total phenolic content and total flavonoid content using galic acid and quercetin, respectively as standard. A single injection of alloxan monohydrate (120 mg/kg, i.p.) prepared in normal saline was administered to produce diabetes in rats, after overnight fasting. For analyzing the rate of contraction of wound, excision wounds sized 4.90cm2 and of 2 mm depth were used. Oral (100, 200 and 400 mg/kg/day; p.o.) and topical treatment with the extract (5% and 10% ointment 50 mg/kg/day) and standard (5% povidone iodine ointment 50 mg/kg/day) was started on the day of induction of wound and continued up to 16 days. The means of wound area measurement between groups at different time intervals were compared using ANOVA and Dunnet’s test. The diabetic wound healing mechanism was studied by measuring the plasma level of glucose, malondialdehyde (MDA) and nitric oxide (NO) in both control and treated groups. For the confirmation of activity, histopathology of the wounds tissues from excision wound model was performed. Results Phytochemical investigations showed the presence of various phytoconstituents (carbohydrates, saponins, alkaloids, glycosides, steroids, flavonoids, tannins). In the ethanolic extract of E. hirta the total phenol content was 285 ± 3.22 mg/g whereas the total flavonoid content was 118.46 ± 1.85 mg/g. In the present study, E. hirta caused significant wound closer both orally (35.92%, 44.69% and 61.42% at the doses of 100, 200 and 400, respectively) and topically (32.86% and 36.32% at the doses of 5% and 10%) treated groups as compared to diabetic control. However, the orally treated groups showed more significant effect than the topically treated groups. Moreover, oral administration of E. hirta ethanolic extract significantly reduced the blood glucose levels in diabetic wound rats (p < 0.01) on day 8 and day 16 as compared to the diabetic wound control (p < 0.01). On the other hand, topical application of E. hirta did not influence the blood glucose levels in diabetic rats (p > 0.05). It also demonstrated a significant decrease in the plasma levels of lipid malondialdehyde and nitric oxide. The results of biochemical parameters were further supported by the histopathological changes of different organs (liver, pancrease, kidney, heart and skin from wound area) which were evidenced through a decrease in inflammatory cell infiltration. Conclusion The present study demonstrates that E. hirta whole plant extract promotes healing of wounds more significantly as compared to diabetic control rats, where healing is otherwise delayed.
