UNASSIGNED: Medical manifestations in the form of incisions, burns, and trauma will trigger a natural wound-healing process that involves complex interactions between cells. Brazilin and other secondary metabolites found in Sappan wood have numerous bioactive qualities, including anti-inflammatory, anti-cancer, and antioxidant properties.
UNASSIGNED: This study aimed to investigate the efficacy of Sappan wood (Caesalpinia Sappan L.) ethanol extract topically on the incision wound healing of albino rats.
UNASSIGNED: Twenty male rats were randomly assigned into five groups with four replications, i.e., (C-) was treated ointment-based, (C+) was treated with 10% povidone-iodine, (T1, T2, and T3 groups) were treated with Sappan wood extract concentration for 6.5%, 15%, and 30%, respectively. The treatment was topically administered to wounded areas twice a day for 15 days. Wound healing was evaluated histologically as the following parameters collagen deposition, polymorphonuclear neutrophils (PMN), angiogenesis, and fibrosis degree using H&E staining. IL-2 level was evaluated using the enzyme-linked immunosorbent assay (ELISA) method. Wound length reduction was calculated on days 8 and 15.
UNASSIGNED: As a result, the 6.5% (T1), 15% (T2), and 30% (T3) Sappan wood extract groups were improved significantly (p < 0.05) compared to ointment-based (C-) and povidone-iodine (C+) groups on the collagen deposition, PMN, angiogenesis, fibrosis degree, and IL-2 level. In particular, the 6.5% (T1) Sappan wood extract group was highlighted significantly (p < 0.05) compared to other groups, evidenced by the improvisation of wound healing parameters and reduction of wound length on days 8 and 15.
UNASSIGNED: In conclusion, a 6.5% Sappan wood extract revealed its applicability to improve incision wound healing in albino rats.

UNASSIGNED: Gingivitis is an inflammation of the gums that is the initial cause of the development of periodontal disease by the activity of Nuclear Factor-kappa B (NF-κB), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), p38, and Tumor Necrosis Factor-α (TNF-α). Unaddressed chronic inflammation can lead to persistent disturbances in other parts of the body. Brazilin is a naturally occurring plant chemical that may have antibacterial and anti-inflammatory effects. Treatment based on the natural plant compound, brazilin, is developed in the form of a topical cream for easy application.
UNASSIGNED: The aim is to develop the natural compound brazilin in the form of a topical cream as an anti-inflammatory agent to reduce NF-κB expression through Imunohistochemistry (IHC) methods, and the expression of pro-inflammatory genes IL-1β, IL-6, p38, and TNF-α.
UNASSIGNED: Male Sprague-Dawley rats were induced with gingivitis using P. gingivalis bacteria. The observed groups included rats treated with a single application of brazilin cream and rats treated with two applications of brazilin cream. The treatment was administered for 15 days. On days 3, 6, 9, 12, and 15, anatomical wound observations and wound histology using hematoxylin-eosin and Masson\'s Trichrome staining were performed. NF-κB protein expression was analyzed using the IHC method. Gingival inflammation gene expression of NF-κB, IL-1β, IL-6, p38, and TNF-α was measured using q-RTPCR.
UNASSIGNED: Single and double applications of brazilin cream increased angiogenesis and decreased NF-κB protein expression, in addition to the IL-1β, IL-6, p38, and TNF-α gene expressions.
UNASSIGNED: In a rat gingivitis model, Brazilin cream may function as an anti-inflammatory agent in the gingival tissue.

UNASSIGNED: Escherichia coli infection is one of the major diarrheal diseases resulting in the loss of pigs at a young age.
UNASSIGNED: This research investigated the antimicrobial activity of Caesalpinia sappan wood extract against E. coli infection as an antibiotic replacement.
UNASSIGNED: E. coli was cultured from diarrheal piglets and then used to find the minimal inhibition concentration (MIC). Caesalpinia sappan wood extract (500 mg/kg) was used for the treatment of diarrheal piglets compared to antibiotics (enrofloxacin 5 mg/kg) by oral administration. Another three groups of diarrheal piglets were used supplemented feed with 1% and 2% extract compared with commercial feed. Subsequently, E. coli enumeration, fecal shape, fecal color, and growth rate were recorded from day 1 to 7.
UNASSIGNED: Based on the results, C. sappan wood extract could inhibit E. coli growth at a MIC of 16-34 mg/ml. The number of colonies did not significantly differ between C. sappan wood extract and enrofloxacin treatment groups. A supplemented feed with 1% and 2% C. sappan wood extract could improve the fecal shape and fecal score compared to the control group, albeit only in suckling pigs. There were significant differences from the control group on days 4, 5, 6, and 7 (p < 0.05). However, the average daily gain did not significantly differ among the three groups.
UNASSIGNED: The results indicate that C. sappan wood extract could improve diarrheal signs in suckling pigs and can be used as a replacement for antibiotics for organic pig production.

BACKGROUND: At present, porcine reproductive and respiratory syndrome (PRRS) caused by the PRRS virus (PRRSV) is one of the most severe epidemics impacting pig farming globally. Despite the fact that a number of studies have been conducted on potential solutions to this problem, none have proven effective. The focus of problem solving is the use of natural ingredients such as plant extracts. Popular throughout Asia, Caesalpinia sappan (CS) is a therapeutic plant that inhibits PRRSV in vitro. Therefore, this study was performed to determine the efficacy of CS extract dietary supplementation on the productive performance, antibody levels, immunological indicators, and lung pathology of PRRSV-challenged weaned pigs. A total of 32 weaned piglets (28 days old) were randomized into 4 groups and kept separately for 14 days. The treatments were organized in a 2 × 2 factorial design involving two factors: PRRSV challenge and supplementation with 1 mg/kg CS extract. The pigs in the PRRSV-challenged groups were intranasally inoculated with 2 mL of PRRSV (VR2332) containing 104 TCID50/mL, while those in the groups not challenged with PRRSV were inoculated with 2 mL of normal saline.
RESULTS: In the PRRSV-challenged group (CS + PRRSV), supplementation with CS extract led to an increase in white blood cells (WBCs) on Day 7 post infection (p < 0.05) and particularly in lymphocytes on Days 7 and 14. The antibody titer was significantly greater in the CS + PRRSV group than in the PRRSV-challenged group not administered CS (PRRSV group) on Day 14 postinfection (S/P = 1.19 vs. 0.78). In addition, CS extract administration decreased the prevalence of pulmonary lesions, which were more prevalent in the PRRSV-challenged pigs that did not receive the CS extract.
CONCLUSIONS: The findings of this study suggest that supplementation with CS extract is beneficial for increasing WBC counts, especially lymphocytes, increasing the levels of antibodies and reducing the prevalence of lung lesions in PRRSV-infected pigs.

Gels containing juca seed galactomannan (JSG) were evaluated for their potential to prevent the progression of dentin erosive wear in an in vitro study with four experimental groups (n = 9). The treatments included distilled water (DW), 0.05% stannous fluoride (121 ppm F), and 0.5% or 1% JSG. The specimens underwent a cycle (3 times/day) consisting of immersion in 1% citric acid (5 minutes), treatment (5 minutes), and artificial saliva exposure (2 hours/overnight) for 5 days. Surface changes were assessed using mechanical profilometry (wear), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The data were analyzed using ANOVA followed by Tukey\'s post-test (p < 0.05). The negative control group exhibited the highest wear (6.0 µm ± 3.5), significantly differing from the group treated with 0.05% stannous fluoride gel (p = 0.007), which showed less dentin loss. The groups treated with 0.5% and 1% JSG showed results similar to the negative control (p = 0.661; p = 0.212, respectively) and the stannous fluoride group (p = 0.103; p = 0.379, respectively). In the SEM images, the specimen treated with stannous fluoride showed obliterated tubules, while the JSG gels formed crystals on the dentin surface, as confirmed by the presence of oxygen and calcium in the EDS analysis. Although the JSG gels showed similar results to the stannous fluoride, did not exhibit superior efficacy at the tested concentrations.

Tara gum (TG) is a polysaccharide extracted from the seeds of a South American tree called Tara (Caesalpinia spinosa). TG is a galactomannan with many applications in the food industry, mainly as an emulsifier and stabilizer agent. In addition, it is also used in the paper and cosmetic industries. In the present study, we performed a molecular characterization based on chemical composition and physicochemical properties to understand the properties behind TG applications. TG was extracted and purified from Tara seeds distributed in different ecoregions of Bolivia. The monosaccharide composition analysis was determined by high-performance anion-exchange chromatography/pulsed amperometric detection (HPAEC-PAD). At the same time, their molecular characteristics, such as molar mass, root-mean-square radius, hydrodynamic radius, conformation, and densities, were studied by asymmetrical flow field-flow fractionation coupled to multi-angle light scattering refractive index (AF4-MALS-dRI), also the specific refractive index increment (dn/dc) was determined for the first time using AF4 for TG. The results revealed that the gum samples are galactomannans composed of mannose (Man) and galactose (Gal) in a ratio of 3.37 (Man/Gal), with an average molar mass range from 2.460 × 107 to 3.699 × 107 Da, distributed in a single population. The root-mean-square radius range from 260.4 to 281.6 nm, and dn/dc is 0.1454. The Kratky plots based on 14 scattering angles indicated that the conformation of all samples corresponds to random coil monodisperse, while their gyration radius/hydrodynamic radius ratio (ρ) is high. All these results suggest that the chains have a low branched density, consistent with the Gal/Man composition. To the best of our knowledge, we report for the first time an integrated physicochemical study of TG relevant to developing emulsifier and stabilizer formulations.

BACKGROUND: Chemotherapy in breast cancer is effective but can generate significant toxicity and lead to tumor resistance. Joint treatment with standardized plant extracts can be an alternative to improve the response and allow an effective activation of the antitumor immune response that favors recovery in the short and long term. The P2Et extract of Caesalpinia spinosa presents antitumor activity in cells and animal models of breast cancer, improves the tumor microenvironment, and induces activation of the specific immune response against the tumor and is synergistic when used together with anthracyclines, which makes it a good candidate for evaluation in patients.
METHODS: Conducted at a single center, this phase II study is a randomized, double-blind, placebo-controlled trial aimed at assessing the safety and efficacy of P2Et extract in patients diagnosed with stage II and III breast cancer, who are eligible for neoadjuvant treatment. The study aims to determine the safety profile at the previously established optimal biological dose from phase I trial while investigating various efficacy outcomes. These outcomes include improvements in quality of life, immunomodulation, metabolic profile, microbiome, as well as clinical indicators such as tumor reduction, disease-free survival, and pathological response, assessed at different stages of the treatment regimen.
CONCLUSIONS: Treatment with the P2Et extract in breast cancer patients is hypothesized to enhance overall well-being, positively influencing their quality of life, while also triggering an antitumor immune response and enhancing immune infiltration. These combined effects have the potential to contribute to improved long-term survival outcomes for patients receiving the phytomedicine alongside neoadjuvant chemotherapy treatment.
BACKGROUND: This trial was registered in the US National Library of Medicine with identifier NCT05007444. First Registered August 16th, 2021. Last Updated: August 9th, 2022.

Paracetamol is the most predominantly used antipyretic and analgesic drug. As paracetamol is metabolised mostly in the liver, both deliberate and unintentional overdoses of paracetamol are reported to provoke severe hepatotoxicity, including liver failure. Caesalpinia bonducella seed is well known for its medicinal and therapeutic properties. However, there is no report on its potential protective effects against paracetamol-instigated hepatotoxicity. Therefore, we studied the protective effects of aqueous seed extract of Caesalpinia bonducella (ASECB) on paracetamol-instigated hepatotoxicity in rats. Thirty female albino rats were divided into five groups: control, paracetamol-intoxicated, ASECB + paracetamol, silymarin + paracetamol, and ASECB alone. The rats were assessed for liver enzyme markers (alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase), antioxidant activity (superoxide dismutase, catalase, reduced glutathione, glutathione peroxidase), lipid peroxidation (malondialdehyde), histopathological, cytokine levels (pro-inflammatory cytokines TNF-α and IL-6, and anti-inflammatory cytokine IL-10), and protein expression (pro-apoptotic markers caspase 3 and caspase 8 and anti-apoptotic marker Bcl-2) after the 8-day study period. Repercussions of paracetamol intoxication induced upregulation of liver enzyme markers, antioxidant depletion, malondialdehyde production, decreased expression of Bcl-2 and IL-10, and overexpression of apoptotic and pro-inflammatory mediators, which were attenuated by pre-treatment with ASECB. ASECB markedly mitigated paracetamol-instigated liver injury by suppressing caspase-8/3 signalling and inflammatory infiltration in liver tissue by significantly reducing TNF-α and IL-6. In conclusion, ASECB pre-treatment exerts potent liver protection against paracetamol-instigated hepatotoxicity evidenced by mitigation of oxidative stress, lipid peroxidation, inflammation, and apoptosis.

Background: The standardization and mechanism of action of  Caesalpinia sappan as an anticancer agent are still lacking. This study aimed to understand the mechanism of action of  C,sappan extract as an anticancer agent. Methods: This study was conducted using the A549 lung cancer cell line to understand the mechanism of action of  C. sappan extract as an anticancer agent. The cytotoxicity activity, cell cycle progression, apoptosis, protein-related apoptosis (i.e., BCL-2and BAX protein) assays, and RNA sequencing were performed level were measured. Moreover, the antioxidant activity, total flavonoids, and phenolics of C.sappan were also assessed. Results: C.sappan has strong antioxidant activity (22.14 ± 0.93 ppm) total flavonoid content of (529.3 ± 4.56 mgQE/g), and phenolics content of (923.37 ± 5 mgGAE/g). The C.sappan ethanol extract inhibited cancer cell growth and arrested at G0/G1 phase of cell cycle, inducing apoptosis by increasing BAX/BCL-2 protein ratio in A549 lung cancer cell line. Furthermore, results from RNA sequencing analysis showed that C.sappan ethanol extract caused downregulation of genes acting on mitochondrial function including adenosine triphosphate (ATP) production and respiration. Conclusions: This study demonstrated that C.sappan has the ability to inhibit cancer cell growth by inducing apoptosis and mitochondrial dysfunction in A549 cells.
