Abstract
Background Diabetes Mellitus is a multisystem chronic pandemic, wound inflammation, and healing are still major issues for diabetic patients who may suffer from ulcers, gangrene, and other wounds from uncontrolled chronic hyperglycemia. Marshmallows or Althaea officinalis (A.O.) contain bioactive compounds such as flavonoids and phenolics that support wound healing via antioxidant, anti-inflammatory, and antibacterial properties. Our study aimed to develop a combination of eco-friendly formulations of green synthesis of ZnO-NPs by Althaea officinalis extract and further incorporate them into 2% chitosan (CS) gel. Method and Results First, develop eco-friendly green Zinc Oxide Nanoparticles (ZnO-NPs) and incorporate them into a 2% chitosan (CS) gel. In-vitro study performed by UV-visible spectrum analysis showed a sharp peak at 390 nm, and Energy-dispersive X-ray (EDX) spectrometry showed a peak of zinc and oxygen. Besides, Fourier transforms infrared (FTIR) was used to qualitatively validate biosynthesized ZnO-NPs, and transmission electron microscope (TEM) showed spherical nanoparticles with mean sizes of 76 nm and Zeta potential +30mV. The antibacterial potential of A.O.-ZnO-NPs-Cs was examined by the diffusion agar method against Gram-positive (Staphylococcus aureus and Bacillus subtilis) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Based on the zone of inhibition and minimal inhibitory indices (MIC). In addition, an in-silico study investigated the binding affinity of A.O. major components to the expected biological targets that may aid wound healing. Althaea Officinalis, A.O-ZnO-NPs group showed reduced downregulation of IL-6, IL-1β, and TNF-α and increased IL-10 levels compared to the control group signaling pathway expression levels confirming the improved anti-inflammatory effect of the self-assembly method. In-vivo study and histopathological analysis revealed the superiority of the nanoparticles in reducing signs of inflammation and wound incision in rat models. Conclusion These biocompatible green zinc oxide nanoparticles, by using Althaea Officinalis chitosan gel ensure an excellent new therapeutic approach for quickening diabetic wound healing.

Antibacterial and phytochemical analysis of traditional medicinal plants: An alternative therapeutic Approach to conventional antibiotics. Heliyon 2023; 9:e22462. [PMID: 38045177 PMCID: PMC10689945 DOI: 10.1016/j.heliyon.2023.e22462] [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: 07/22/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 12/05/2023] Open
Abstract
The purpose of this study was to carry out antibacterial and phytochemical analyses on six selected medicinal plants that have been traditionally used by the local people to treat and control different diseases. The antibacterial activities of methanolic extracts of these plants were assessed using the Agar well diffusion and Microtiter broth dilution methods. The root extract of Andrachne aspera showed significantly (p < 0.05) highest mean zone of inhibition at concentrations of 100 mg/ml (33 ± 0.17) and 200 mg/ml (33.5 ± 0.84) against S. epidermidis. The second highest mean zone of inhibition (24.8 ± 0.41) was recorded by Dichrostachys cinerea leaf extract against S. epidermidis at 200 mg/ml concentration. The minimum inhibitory concentrations 1.0 ± 0.0 was recorded by Andrachne aspera against E. faecalis and 2.0 ± 0.0 against S. aureus by Dichrostachys cinerea. The preliminary phytochemical analysis showed that Andrachne aspera and Dichrostachys cinerea contained strong concentration of Polyphenols and Flavonoids. Therefore, these two medicinal plant species have promising potential for further detailed investigations, including safety tests, characterization and isolation of bioactive secondary metabolites for the development of alternative drugs.

[PMID: 37701854 PMCID: PMC10494916 DOI: 10.2147/jep.s426233] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 08/29/2023] [Indexed: 09/14/2023] Open
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.

Evaluation of Wound Healing and Anti-Inflammatory Activities of 80% Methanol Crude Extract and Solvent Fractions of Trichilia dregeana Sond (Meliaceae) Leaves in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:9980866. [PMID: 36714535 PMCID: PMC9879677 DOI: 10.1155/2023/9980866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 11/30/2022] [Accepted: 12/02/2022] [Indexed: 01/21/2023]
Abstract
Introduction The leaves of Trichilia dregeana Sond are traditionally used to treat wounds. Even though there have been in vitro studies and claims supporting wound healing, there are no scientific data on in vivo wound healing and anti-inflammatory activities of the leaves of T. dregeana. Objective This study aimed to evaluate wound healing and anti-inflammatory activity of 80% methanol crude extract and solvent fractions of T. dregeana in mice. Method The leaves of T. dregeana were dried, ground, and macerated with 80% methanol three times successively. The crude extract was fractioned by water, ethyl acetate, and hexane separately. The acute dermal and oral toxicity tests were done by applying 2000 mg/kg of 10% (w/w) crude extract ointment (CEO) topically and 2000 mg/kg of crude extract orally, respectively. The wound healing activity of the crude extract was evaluated on excision, incision, and burn wound models while the fractions were evaluated only on excision wound model. The anti-inflammatory activity of the crude extract was evaluated on xylene-induced ear edema and cotton pellet granuloma tests. Result Both acute dermal and oral toxicity tests were found to be safe after topical application of 2000 mg/kg of 10% (w/w) CEO and oral administration of 2000 mg/kg of crude extract suspension, respectively. Both 5% and 10% (w/w) CEO produced significant (p < 0.001) wound contraction and period of epithelialization from day 4 onwards as compared to simple ointment (SO) on both excision and burn wounds. The tensile strength was increased significantly (p < 0.001) for the CEO-treated mice as compared to both untreated and SO groups. The crude extract also showed anti-inflammatory activity at 100, 200, and 400 mg/kg by inhibiting ear edema, exudate, and granuloma formation as compared to the SO group. Conclusion The increase in wound contraction, reduction in period of epithelialization, and increase in tensile strength support the traditional claims of T. dregeana for 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
Background The root of Stephania abyssinica (Dill. and A. Rich.) Walp. (Menispermaceae) is traditionally used to treat wounds. Despite the fact that there have been in vitro studies and claims supporting wound healing, there has been no scientific data on the in vivo wound healing activities of the root of S. Abyssinica. Objective The aim of the study was to evaluate the wound healing activity of 80% methanol root extract and solvent fractions of S. Abyssinica in mice. Methods The roots of S. Abyssinica were air dried, ground and macerated by 80% methanol three times successively. The crude extract was fractionated by water, hexane and ethyl acetate separately. The acute dermal toxicity test was done by applying 2000 mg/kg of the 10% w/w crude extract. Wound healing activity of crude extract was evaluated on excision, incision and burn wound models, while the fractions were evaluated on excision wound model only. Results In mice, an acute dermal toxicity test of 2000 mg/kg of the 10% w/w crude extract was found to be safe. The 10% w/w crude extract ointment (CEO) produced significant (p < 0.001) wound contraction from 4th to 16th post wounding days, and the 5% w/w CEO were significant (p < 0.01) wound contraction on 10th post wounding day as compared to simple ointment (SO) treated group on excision wound. On burn wound models, the CEO showed highly significant (p < 0.001) from the 6th post wounding days onwards. The tensile strength was increased significantly (p < 0.001) by the CEO treated mice as compared to the untreated group and SO group. Conclusion The data obtained from this study showed 80% methanol crude extract, the aqueous and the 10% w/w ethyl acetate fraction possessed better wound healing activities, and decreased period of epithelialization.

Abstract
Background Withaniasomnifera is an important medicinal plant for the treatment of diarrhea in Ethiopian folklore medicine. The aim of this study was to evaluate the antidiarrheal activity of Withania somnifera leaves in Swiss albino mice. Materials and Methods Hydromethanolic crude extraction and solvent fractionation were done using cold maceration technique. 80% methanol was used as a solvent in crude extraction, while distilled water, n-butanol, and chloroform were employed during fractionation. Castor oil-induced diarrhea, enteropooling, and gastrointestinal motility models were employed to evaluate antidiarrheal activity. Mice were randomly divided into five groups (six mice per group): negative control, which received 2% Tween 80 in distilled water; positive control, which received 3 mg/kg loperamide; and three test groups (III, IV, and V), which were treated with 100 mg/kg, 200 mg/kg, and 400 mg/kg of crude extract and solvent fractions, respectively. Results The crude extract, aqueous, and n-butanol fractions significantly delayed the onset of diarrhea at 200 mg/kg and 400 mg/kg dose. There was a significant reduction in the number and weight of stools at all tested doses of the crude extract and aqueous fraction, and at 200 mg/kg and 400 mg/kg of n-butanol fraction. Significant reduction in volume and weight of intestinal contents was observed at all tested doses of the crude extract, and at 200 mg/kg and 400 mg/kg of aqueous and n-butanol fractions. All tested doses of the crude extract and 200 mg/kg and 400 mg/kg of the aqueous and n-butanol fractions significantly reduced the motility of charcoal meal. Conclusion This study demonstrated that the crude extract and solvent fractions of the Withania somnifera leaves have antidiarrheal activity and supported the folklore use of the plant.

[PMID: 34290516 PMCID: PMC8289443 DOI: 10.2147/jir.s321241] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 06/23/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose The potential cardio-protective property of germinated brown rice (GBR) has been revealed by ameliorating risk factors related to cardiovascular diseases. This study hypothesized that the combination of GBR and cardioplegic solution could protect the cardiomyocytes exposed to simulated ischemic reperfusion injury in vitro study and preserve cardiac function during cardiopulmonary bypass surgery in animal models. Methods Primary porcine cardiomyocytes were isolated and experimented cell viability against simulated ischemic reperfusion injury. In a cardiac surgical animal model, six pigs were randomly assigned to receive the two types of cardioplegic solution: i) St. Thomas cardioplegic solution (20 cc/kg); and ii) St. Thomas cardioplegic solution plus GBR (1 mg/kg). During open-heart surgery, the aorta was cross-clamped for 20 minutes, followed by reperfusion for 1 hour. Cardiopulmonary bypass parameters were recorded until the end of the procedure. Furthermore, hemodynamic parameters and arterial blood gas characteristics of animals among groups were monitored at different time points, including baseline before cardiopulmonary bypass (T1), during cardiopulmonary bypass (T2), during aortic clamp on (T3), and aortic clamp off (T4). Results Primarily, GBR cotreatment with cardioplegic solution essentially resulted in the improvement of cell viability in primary porcine cardiomyocytes against simulated ischemic reperfusion induction. The findings from cardiac surgery demonstrated that mean arterial pressure and heart rate are constantly stable in cardioplegic solution combined with the GBR group, while the trend of potassium and lactase concentration was decreased in the animals receiving GBR group. Consistently, all parameters from arterial blood gas showed better outcomes in animals receiving GBR; however, there were no statistically significant differences between groups, except hepatic enzymes. Conclusion Therefore, GBR might exert cardio-protective effects against ischemic reperfusion injury in the porcine cardiac surgery model due to anti-inflammatory response. These protective actions of GBR may explain the benefits gained from applying GBR products as a possible therapeutic supplement on cardiac diseases.
