Ecotoxicological and metabolomic investigation of chronic exposure of Daphnia magna (Straus, 1820) to yttrium environmental concentrations

In order to estimate the effects on aquatic organisms of long-term exposure to low doses of yttrium (Y) as a potential emerging contaminant, ecotoxicological and metabolomic data were collected on the model organism Daphnia magna, a keystone species in freshwater ecosystems. Following an initial acute toxicity assessment, a 21-day chronic exposure experiment was conducted using a sublethal concentration of 27 μg L⁻¹ of Y, corresponding to the effective concentrations inducing 10 % effect (EC10) value for mortality endpoint and simulating the environmental Y level in aquatic systems. Results from the 21-day two-factor experiment combining microcrustacean survival, growth and reproduction bioassays and targeted gas chromatography-mass spectrometry (GC–MS) metabolomics indicated significant adverse effects of chronic exposure to Y on D. magna. Daphnids exposed to Y exhibited a significantly lower survival at day 21, delayed the maturity stage, including their first breeding, and decreased clutch size. On the side of metabolomics, a clear and general increase over time of both the number and the level of detected metabolites in the hydroalcoholic extracts of the whole organisms was observed. However, emerging from this broad temporal pattern, several bioactive metabolites were identified (e.g., 2,4-di‑tert‑butylphenol, itaconic acid, 3-hydroxybutyric acid, and trehalose) whose levels in extracts are linked to the presence of Y. These results emphasize the necessity of considering low-dose, long-term exposure scenarios in environmental risk assessments of rare earth elements (REEs), which have often been overlooked in favour of higher concentration studies.

Evaluation of the Protective Effect of Hydroalcoholic and Aqueous Extracts of Ulmus minor Leaves on Ulcerative Colitis Induced by Acetic Acid in Rats

Background: Ulcerative colitis (UC) is a chronic inflammatory disease of the large intestine that cannot be cured, but its symptoms can be managed. Objectives: This study aimed to evaluate the protective effects of hydroalcoholic and aqueous extracts of Ulmus minor leaves on UC induced by acetic acid in rats. Methods: Rats were randomly divided into seven groups of five, and 3% acetic acid was used to induce colitis. To assess the protective effect of Ulmus minor leaves, macroscopic, microscopic, and histological evaluations were performed on the different study groups. Results: Macroscopic examinations of both the hydroalcoholic and aqueous extract groups showed that the aqueous extract at a dose of 200 mg/kg provided the best protective effect on colon tissue. Rats treated with hydroalcoholic extracts at doses of 100 mg/kg and 200 mg/kg, as well as those treated with aqueous extract at 100 mg/kg, also showed favorable outcomes compared to the control group, with a significant difference (P < 0.05). Furthermore, among the groups treated with hydroalcoholic and aqueous extracts, the aqueous extract at 200 mg/kg demonstrated the most protective effects based on microscopic and histological evaluations of the colon. Conclusions: The extracts of Ulmus minor leaves demonstrated anti-inflammatory properties in an animal model of colitis. Further studies are required to evaluate their potential therapeutic benefits in patients with UC.

Apodanthera glaziovii (Cucurbitaceae) Shows Strong Anti-Inflammatory Activity in Murine Models of Acute Inflammation.

Background/objectives:Apodanthera glaziovii is an endemic species from the semi-arid Brazilian, which has limited toxicological and pharmacological studies. This species belongs to a well-studied family known for its bioactive compounds used in treating inflammatory. This study aimed to identify secondary metabolites in the stems from A. glaziovii, evaluate toxicity, and investigate the anti-inflammatory potential of the stem hydroalcoholic extract (SHE-Ag). Methods: qualitative and quantitative assays were employed to identify secondary metabolites, along with chromatographic analyses and 1H and 13C NMR. Toxicity was assessed through in vitro hemolytic toxicity, in vivo genotoxicity, and oral acute toxicity tests before the pharmacological assays were conducted. Results: phytochemical screening, HPLC and NMR analyses suggested the presence of saponins of the norcucurbitacin class. The SHE-Ag exhibited no hemolytic activity and no mutagenic potential. However, in vivo toxicity at a dose of 2000 mg/kg revealed hematological and biochemical alterations, while the 500 mg/kg dose was safe. In the anti-inflammatory assays, SHE-Ag at 100 mg/kg reduced paw edema by 55.8%, and leukocyte and neutrophil migration by 62% and 68% in the peritonitis model, respectively; inflammatory cell migration by 70% in the air pouch model, outperforming indomethacin, which showed a 54% reduction. Conclusions: these findings indicate that SHE-Ag is rich in saponins, confirmed through HPLC and 1H and 13C NMR analyses. The SHE-Ag also demonstrated low toxicity. The inflammation models used showed a reduction in inflammation, pro-inflammatory cells, and edema, highlighting the significant anti-inflammatory activity of hydroethanolic extract A. glaziovii stems.

Saffron metabolites were more effective than ginger metabolites on both microorganisms.

Antibacterial, antioxidant, and anti-giardia properties of the essential oil, hydroalcoholic extract, and green synthesis of the silver nanoparticles of Salvia mirzayanii plant

In this study, an environmentally-friendly, simple, and low-cost approach was developed for the production of silver nanoparticles (Ag NPs) accelerated by Salvia mirzayanii plant. The identification process involved ultraviolet-visible (UV-Vis) spectrophotometry, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), and scanning electron microscopy (SEM). The UV–Vis spectrum exhibited a peak at 450 nm which is a characteristic surface plasmon resonance of Ag NPs. The XRD and EDS analyses confirmed the crystalline nature and the presence of silver element, while the SEM analysis displayed the production of almost spherical nanoparticles. The FTIR spectrum exhibited that the Ag NPs were functionalized with biomolecules found in the extract, which are involved in the production and stabilization of the NPs. The antibacterial activity of the essential oil, the hydroalcoholic extract and Ag NPs was examined against antibiotic-resistant bacteria, Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli). The anti-Giardia activity was tested on Giardia lamblia cysts at different time intervals. The results exhibited that the MIC values for essential oil, hydroalcoholic extract and Ag NPs against S. aureus were 1.65 µL/mL, 75 mg/mL, and 0.125 mg/mL respectively. The MBC was attained 6.25 µL/mL, 300 mg/mL, and 0.25 mg/mL, for essential oil, hydroalcoholic extract and Ag NPs, respectively. The MIC values for essential oil, hydroalcoholic extract and NPs against E. coli were 3.12 µL/mL, 150 mg/mL, and 0.06 mg/mL, respectively. The MBC was determined to be 50 µL/mL, 300 mg/mL, and 0.25 mg/mL for essential oil, hydroalcoholic extract and Ag NPs, respectively. In addition, the antioxidant activity was determined using the ferric reducing antioxidant power (FRAP) test. The results indicated that the essential oil of this plant exhibited the highest antibacterial and anti-giardial properties, whereas its extract demonstrated the strongest antioxidant properties.

Protective Effects of Hydroalcoholic Leaf Extract of Origanum Vulgare against Paraquat-induced Lung Toxicity in Rats: The Role of the Inflammation-related Markers and Oxidative Stress

Background:: The pesticide paraquat is hazardous to both humans and animals. Lung damage is a common complication of paraquat poisoning. Objective:: This research analyzes the preventive properties of Origanum vulgare leaf extract against paraquat-induced acute pulmonary toxicity and oxidative stress. Methods:: In this experiment, the rats were assigned to five distinct groups. Group 1 served as the control, group 2 got only 25 mg/kg bw paraquat, and groups 3, 4, and 5 received paraquat and Origanum vulgare leaf extract at dosages of 200, 400, and 800 mg/kg bw, respectively. In rats, inflammation- related indicators and oxidative stress were analyzed after therapy. Results:: Compared with the control group, the levels of the serum PC, MDA, and inflammatory markers such as TNF-α, IL-6, and IL-1β remarkably rose (p < 0.05) and the pulmonary contents of the SOD, CAT, and vitamin C greatly decreased (p < 0.05) in the paraquat-only group. Origanum vulgare leaf extract administration after paraquat exposure resulted in a substantial increase in lung SOD, CAT, and vitamin C levels as well as a significant reduction in MDA, PC, and lung inflammatory markers (TNF-α, IL-6, and IL-1β) gene expression relative to the paraquat-only group. Conclusion:: Origanum vulgare leaf extract might be supplied to lessen the toxicity of paraquat, based on the findings of this research, which indicated that Origanum vulgare leaf extract has antioxidant- enhancing properties and can improve the antioxidant defense system. other: Ethic number: IR.

Exploring the Antibacterial Activity of Ipomoea staphylina Extracts Against H. pylori: A Pharmacognostic Investigation of Whole Plant and Matured Stem with Emphasis on Quercetin Isolation.

Ipomoea staphylina Rome & Schult, entrenched in ethnomedicinal practices, is recognised for its efficacy in treating stomach disorders. Traditionally used in Dharmapuri, Tamil Nadu for stomach ulcers, its matured stem bark latex is therapeutically relevant, especially for Helicobacter pylori (H. pylori) infections. This prompts scientific exploration into its antibacterial properties. The research validates the antibacterial efficacy of I. staphylina extracts against H. pylori, scrutinising the whole plant and matured stem through a comparative pharmacognostic analysis. Utilising herbal standardisation techniques, we confirm the heightened purity of the powder. Antimicrobial assessments show exceptional efficacy of DME (dried Ethanolic extract of I. staphylina) and HLS (hydro alcoholic extract of I. staphylina) extracts. Quercetin isolation by using advanced instrumentation (Nuclear magnetic resonance [NMR], High resolution mass spectrometry [HR-MS], High-performance thin-layer chromatography [HPTLC], Fourier transform infrared spectroscopy [FTIR]) ensures precise compound identification. This methodology guarantees an exhaustive analysis, confirming purity and identifying bioactive components. Standardisation underscores the elevated purity of I. staphylina, with phytochemical screening revealing a predominant presence of phenolics and flavonoids. Antibacterial investigations highlight significant activity, particularly with DME and HLS extracts. These findings substantiate I. staphylina's medicinal significance, especially its matured stem latex, as a promising treatment for H. pylori-induced stomach ulcers, affirming traditional use by Dharmapuri villagers.

Rosmarinus officinalis and Zataria multiflora extracts enhanced antibacterial activity of ciprofloxacin against methicillin-resistant Staphylococcus aureus.

The study investigates the antibacterial potential of hydroalcoholic extracts from Rosmarinus officinalis and Zataria multiflora, combined with ciprofloxacin, against methicillin-resistant Staphylococcus aureus (MRSA). Initial screening showed promising results, leading to further exploration of the synergistic effect of the extracts and ciprofloxacin. The combination of the two extracts had an additive effect, while the combination of each extract with ciprofloxacin resulted in partial synergism. The most significant synergistic effect was observed against MRSA 9, with a 3200-fold reduction in the MIC value of ciprofloxacin. The similar inhibitory concentration of the extracts for all MRSA strains suggests these non-antibiotic agents have a broad spectrum of activity against MRSA. This offers a promising avenue for developing new therapeutic approaches to tackle drug-resistant bacterial infections. The results highlight the potential of combining R. officinalis and Z. multiflora extracts with ciprofloxacin to enhance antibacterial efficacy against MRSA strains.

Coupling crossflow microfiltration and nanofiltration for the concentration of aroma compounds in a raspberry hydroalcoholic extract

AbstractThis work investigated the coupling of microfiltration (MF) and nanofiltration (NF) to concentrate the volatile compounds in a raspberry hydroalcoholic extract. Enzymatic treatment increased the MF permeate flux by 30%–50%. The highest MF permeate flux was above 50 kg·h−1·m−2 at a mass reduction ratio of 5. MF allowed efficient clarification of the extract without significant retention of aroma compounds. Among the NF membranes tested using the MF permeate as feed, one membrane was clearly more effective in concentrating the extract in terms of flux (19 kg·h−1·m−2 at 35 bar), retention of aroma compounds (average retention of 85%), phenolic compounds (61%) and dry matter (90%). Three other membranes were of interest for the fractionation of volatiles in both permeate and retentate but with a lower permeate flux. Finally, one membrane retained few aroma compounds but showed 70% dry matter retention, making it a promising method for aroma purification versus dry matter content in the permeate.Practical ApplicationsIn this study, we investigated the coupling of crossflow MF and NF with a pectinolytic pretreatment, in order to concentrate the aroma compounds from a raw organic raspberry extract. The aim was to avoid aroma degradation and reduce the operating costs, compared to the conventional concentration thermal technologies. Few authors have studied aroma concentration by NF, which presents an interesting area of research for industrial applications. This work provides keys for flavor manufacturers to add value to their products at a low cost and with limited environmental impact, producing concentrated natural aroma extracts for food. Another originality of this work for industrial companies was to show that thanks to the same process, several fractionations could be achieved simply by modifying the operating conditions. Therefore, this work contributed to propose new applicable processing for the production of natural flavors in a context of high consumer and market demand for organic ingredients.

Protective Effects of Wild Sulla coronaria (Fabaceae) Flowers Phytocomplex in Human Dermal Fibroblasts Stimulated with Interleukin-1β

Sulla coronaria is indigenous to the Mediterranean region. It is grown as fodder in southern Italy because it contains various secondary metabolites with beneficial activities on animals. Recently, its potential use in cosmeceutical treatments for skin problems was reported. In this scenario, to contribute to a possible cosmeceutical application, we characterized the phytochemical profile of Sulla coronaria flowers’ hydroalcoholic extract by HPLC-DAD, Folin-Ciocalteu, Aluminum Chloride methods, DPPH assay, and, for the first time, we evaluated the antioxidant and anti-inflammatory activities on dermal fibroblasts. The phytochemical analysis confirmed the significant content of phenolic compounds (TPC 69.8 ± 0.6 mg GAE/g extract, TFC 15.07 mg CE/g extract) and the remarkable presence of rutin, quercetin, and isorhamnetin derivatives that give to the phytocomplex a good antioxidant activity as highlighted by the DPPH assay (IC50 of 8.04 ± 0.5 µg/mL). Through the reduction in NO• and ROS levels in human dermal fibroblasts, the biological tests demonstrated both the safety of the extract and its ability to counteract the inflammatory state generated by Interleukin-1β exposure. Our findings indicate that the antioxidant activities of the phytocomplex are strictly related to the anti-inflammatory action of the Sulla coronaria flowers extract, confirming that this plant could be a valuable source of bioactive molecules for cosmeceutical and nutraceutical applications.

Storage stability of phycobiliproteins in a hydroalcoholic solution evaluated by an optical method

The aim was to evaluate the stability of pigments of the phycobiliprotein group extracted from the biomass of the Spirulina (Arthrospira) platensis cyanobacterium and the Porphyridium purpureum red microalgae. Water extracts of phycobiliproteins were obtained following a double freezing of the raw biomass of Arthrospira platensis and Porphyridium purpureum. An extraction was carried out with a phosphate buffer (0.05 M, pH = 7) in the cold (5 °C) for 24 hours. To the extracts obtained, 96% ethanol was added until its concentration in the solution was 20%. The hydroalcoholic extracts of phycobiliproteins were stored for three months. Pigment concentrations were monitored by an optical method. The allophycocyanin pigment demonstrated the highest storage stability. The highest degradation rate of phycobiliproteins was observed during their storage in the light at room temperature. The degradation rate of pigments under these conditions was 9and 80-fold higher (for B-phycoerythrin and C-phycocyanin, respectively) than similar indices during their storage in the dark and in the cold. C-phycocyanin was the least stable, compared to other studied phycobiliproteins. Its degradation rate under all storage options was 5to 10-fold higher than that of B-phycoerythrin under similar conditions. An essential conservation requirement for C-phycocyanin and β-phycoerythrin in hydroalcoholic solutions was the absence of light. For C-phycocyanin, a low temperature was necessary as well. Storage of B-phycoerythrin in the dark at room temperature is acceptable. These conditions can ensure the conservation of up to 86% of pigments in hydroalcoholic solutions for 25–30 days.

Role of Hydroalcoholic Extracts of Aegle marmelos (AM) Leaves and Tamarindus indica (TI) Seeds on High Fat High Sugar Diet Induced Hyperlipidemia in Rodent Models

Hyperlipidemia is an increase in plasma levels of lipids (cholesterol, triglycerides) and various lipoproteins. Though many drugs have been used for controlling hyperlipidemia, yet most of them have unpleasant side effects, which has stimulated the search for natural remedies. Hypolipidemic activity of hydroalcoholic extracts of Aegle marmelos (AM) leaves and Tamarindus indica (TI) seed alone and in combination on High Fat High Sugar (Fructose) Diet (HFHSD) induced hyperlipidemia in male rats was evaluated in this study. Out of 54 male Sprague Dawley rats, six received standard diet (Group I, normal control) throughout the study. The remaining 48 rats were fed orally with HFHSD for 30 days to induce hyperlipidemia (plasma cholesterol level >200 mg/dL). For the next thirty days, rats which had received HFHSD were divided into 8 groups with six animals in each. Group II- HFHSD control received standard diet, Group III- positive control (Niacin, 100 mg/kg/day), Group IV - AM25 (25 mg/kg/day), Group V - AM50 (50 mg/kg/day), Group VI - TI25 (25 mg/kg/day), Group VII - TI50 (50mg/kg/day), Groups VIII - AM25+TI25 (25 + 25 mg/kg/day) and Group IX - AM50+TI50 (50 + 50 mg/kg/day). Treatment of HFHSD fed rats with each extract alone and in combination resulted in a significant decrease in plasma cholesterol, triglycerides, LDL and VLDL and increase in HDL levels. Treatment with AM50+TI50 significantly lowered plasma cholesterol (p<0.001), triglycerides (p<0.001) and increased HDL cholesterol levels (p<0.05), in comparison to positive control. Both the extracts alone and in combination exerted hypolipidemic effect in rats.

Combination of medicinal plants with antibiotics against Klebsiella pneumoniae and Acinetobacter baumannii

Background and aims: One essential plant-based strategy to deal with infections is antimicrobial synergism, which can make antimicrobials more efficient. The aim of this study was to investigate the interaction between these extracts and two widely used antibiotics, meropenem and gentamicin, on two multidrug-resistant (MDR) bacteria, K. pneumoniae and A. baumannii, in vitro. Methods: Different concentrations of Rosa damascena Mill., Malva sylvestris L., and Zataria multiflora Boiss. hydroalcoholic extracts (2-fold serial dilution from 131072 to 256 μg/mL) were administered against two MDR bacteria, and their combination with gentamicin and meropenem (serial dilution from 32 to 0.015 μg/mL) was investigated by the resazurin-based microdilution and the checkerboard method. The phytochemical properties of the extracts were also examined, and the total phenolic content (TPC), total flavonoid content (TFC), anthocyanin content, and antioxidant capacity of the extracts were determined. Results: Z. multiflora and R. damascena showed high antibacterial activity, and their minimal inhibitory concentrations on Acinetobacter baumannii were 1024 and 2048 μg/mL, respectively. Z. multiflora also had high TFC, TPC, and antioxidant activity and demonstrated additive interaction with meropenem and gentamicin with fractional inhibitory concentrations of 1 and 0.75, respectively. Conclusion: We suggest the potency of Z. multiflora-antibiotic combinations in treating MDR A. baumannii after future clinical studies.

Effect of hydroalcoholic extract of Tanacetum parthenium on gene expression and paraoxonase 1 enzyme activity: An experimental and molecular dynamic study

Background and aims: Cardiovascular diseases are among the most common causes of death worldwide. The paraoxonase 1 (PON1) enzyme is a main factor in preventing these diseases. This study investigated the effect of hydroalcoholic extract of Tanacetum parthenium plant on the activity and gene expression of PON1. Methods: Forty male rats were divided into 4 groups: a control group, a hyperlipidemic group, and two hyperlipidemic groups that were treated with 400 and 800 mg/kg of hydroalcoholic extract. Arylesterase activity of PON1 and serum triglyceride and cholesterol levels were measured. Moreover, the gene expression of PON1 in the liver tissue samples was measured using real-time PCR. Finally, molecular dynamics studies of apigenin as a main compound in the plant were performed to investigate the activity of PON1 in the simulated environment. Results: Hydroalcoholic extract of T. parthenium decreased serum triglyceride (from 105.8±10.1 to 60.5±21.5 and 50.9±11.2 mg/dL) and total cholesterol (from 97.5±16.8 to 59.6±8.5 and 52.0±9.6 mg/dL) levels, while it increased the activity of arylesterase paraoxonase1 significantly (P<0.001). It also showed a significant (P<0.001) effect on PON1 gene expression. However, the dose of 800 mg/kg was more effective. The results of simulation and molecular dynamics showed that apigenin binds to PON1 with a high affinity and induces changes in the molecular dynamics parameters. Conclusion: The 800 mg/kg of hydroalcoholic extract of T. parthenium can increase the activity of PON1 and its gene expression. It seems that apigenin as one of the most important antioxidant compounds of this plant can increase the activity of this enzyme by direct binding to PON1.

Regarding to the side effects of chemical drugs, medicinal plants, according to their unique properties such as cheapness, naturalness and availability, and without any significant side effects, medicinal plants have recently been considered in the prevention of diseases. In this laboratory research, the cytotoxic effect of hydroalkolic extract of Daphne mucronata Royle on cell viability of A2780 cancer cell and the expression of MAPK8 and PTK2 genes in the cells treated with the Ephedra plant extract during three-time interval 24,48 and 72 hours after treatment were investigated. Methods: The inhibitory effect of hydroalcholic extact of D. mucronato on targeted cells was done using MTTassay then, expression level of MAPK8 and PTK2 genes in cells treated with plant extract were investigated using qRT-PCR method. Data analyses were done using GraphPad prism software. Results: Regarding to the results of cell viability, IC50 rate for 24, 48 and 72h after treatment were determined as 105.40, 85.98 and 81.38µg/mL, respectively. Expression analysis of tested genes showed that hydroalcoholic plant extract of D. mucronato had not significant effect on expression of targeted genes (Pvalue≤0.05) so that there was no significant difference on their expression level compared to the control. Conclusion: According to the results, it can be concluded that D. mucronato extract had a significant inhibitory effect on treated A2870s cancer cells, but it was not able to change the expression level of genes involved in anticancer activities and its molecular pathways. The use of bio-markers and other gene pathways is suggested for additional studies.

Also, the anti-candidal activity of the herbal cream was determined in the fungus Candida albicans. The results obtained indicated that the herbal cream containing hydroalcoholic extract of the selected plant possesses significant anti-candidal activity and hence it may used in the treatment of fungal infection.

Unveiling the Multi-Targeted Mode of Action: Investigating the Antiepileptic Activity of Murraya koengii Extract in PTZ-induced Seizures.

Recurrent seizures are the hallmark of the neurological condition known as epilepsy. Murraya koenigii (curry leaves) has been traditionally used in medicine for various ailments. This study aimed at the anticonvulsant activity of HAEMK using a petylenetetrazole (PTZ) induced seizure model. Behavioral and biochemical parameters were assessed to determine the effectiveness of the extract in mitigating seizures. Albino mice were orally administered with different doses of the extract prior to PTZ administration. The behavioral parameters, including seizure latency, duration and severity, were monitored and recorded. Additionally, acetylcholine esterase, GSH, and malondialdehyde (MDA), three indicators of oxidative stress, were assessed in brain tissue homogenates. HAEMK-treated groups demonstrated a substantial increase in seizure latency and a decrease in seizure length and intensity compared to the control group. A dose-dependent MDA and acetylcholine esterase decreased concurrent GSH rise were seen in the HA-treated groups. These findings suggest that the hydroalcoholic extract of M. koenigii possesses antiepileptic activity, possibly mediated through its antioxidative mechanisms.

Effect of hydroalcoholic extract of Sambucus nigra on superficial digital flexor tendon repair in rabbit by ultrasonography and histopathology.

Adult tendon tissue has limited and slow regenerative capacity. Sambucus nigra plant possesses antioxidant and anti-inflammatory attributes. This study aimed to evaluate the effect of hydroalcoholic extract of this plant's fruit on superficial digital flexor tendon repair in rabbits (SDFT). Twenty-five male New Zealand white rabbits weighing 1.5-2kg were selected, quarantined and randomly divided into four groups of six. By performing a partial left posterior limb tenotomy, differentiating the SDFT and creating multiple scrapes were performed. During 3 consecutive days post-surgery, the positive control group was injected with 0.5mg/kg dexamethasone, whereas the treatment groups received extract doses of 200 and 400mg/kg, respectively. The negative control group did not receive any medication. Evaluation of sonographic and histopathological parameters was conducted on days 0, 7 and 28 post-surgeries. Findings were analysed and compared using SPSS22. Both treatment groups showed significant differences in echogenicity, and collagen fibre alignment compared to the control and positive control groups, in sonographic evaluation. Histopathological examination revealed fewer inflammatory cells and increased collagen fibre formation in the treatment groups compared to the other two groups. No significant difference in angiogenesis was observed among the groups on days 7 and 28 (p value <0.05). The results indicate that the S. nigra fruit extract, by stimulating collagen synthesis and reducing inflammation, effectively accelerates the healing process of injured tendons.
