Effects of dietary pretreated Chinese herbal medicine supplementation on production performance, egg quality, uterine histopathological changes, and antioxidant capacity in late-phase laying hens. Front Physiol 2023; 14:1110301. [PMID: 36744028 PMCID: PMC9895833 DOI: 10.3389/fphys.2023.1110301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 01/11/2023] [Indexed: 01/21/2023] Open
Abstract
Aims: The study aimed to evaluate the effects of pretreated Chinese herbal medicine (PCHM) on egg quality, production performance, histopathological changes in the uterus, antiox idant capacity, and antioxidant gene expression in late-phase layers. Methods: Jinghong No.1 layers (n = 360, 68 weeks old) were assigned randomly to one of f our dietary interventions. Each treatment was replicated six times. Repeat 15 chickens per g roup. All birds were fed a diet composed of a corn-soybean meal-based diet supplemented with 0, 0.2, 0.4, or 0.8% PCHM for 6 weeks. Results: Dietary PCHM supplementation had no significant effects on laying rate, feed con sumption, yolk color, and shape index. With increasing PCHM level the Haugh unit linearly increased (P < 0.05). Supplementation of 0.8% PCHM increased egg weight, compared with the control (P < 0.05). PCHM can effectively alleviated the pathological changes caused by aging in the uterus including hemorrhage, and many inflammatory cell infiltrations. Supplementation of 0.4% PCHM increased glutathione peroxidase (GSHPx) in liver, magnum, and plasm considerably, compared with the control (P < 0.05). Supplementation of PCHM decr ease in the liver, magnum, and uterus on malondialdehyde (MDA) content, compared with the control (P < 0.05). Compared with the control group, mRNA expressions of glutathione peroxidase 1 (GPX1), peroxidase 4 (GPX4), catalase (CAT), and nuclear factor E2-related factor 2 (Nrf2) in the magnum, liver, and uterus were dramatically rose in the 0.4% PCHM supplementation group (P < 0.05). In summary, dietary supplementation after PCHM increased egg weight and quality in late-phase laying hens. Conclusion: Dietary PCHM increased the antioxidative capacity of late-phase laying hens, which could be associated with increased mRNA expression of antioxidant enzymes and Nrf2. These findings provide potential for using PCHM to increase the production performance in late-phase laying hens.

Protective Effect of Bojungikki-Tang against Radiation-Induced Intestinal Injury in Mice: Experimental Verification and Compound-Target Prediction. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:5417813. [PMID: 36644439 PMCID: PMC9833920 DOI: 10.1155/2023/5417813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 12/05/2022] [Accepted: 12/12/2022] [Indexed: 01/05/2023]
Abstract
Bojungikki-tang (BJIT) is a traditional herbal medicine used in Korea, Japan, and China to treat gastrointestinal disorders. In this study, we aimed to investigate whether BJIT has protective effects against radiation-induced intestinal injury and to predict the underlying therapeutic mechanisms and related pathways via network pharmacological analyses. BJIT was injected intraperitoneally (50 mg/kg body weight) to C3H/HeN mice at 36 and 12 h before exposure to partial abdominal irradiation (5 Gy and 13 Gy) to evaluate the apoptotic changes and the histological changes and variations in inflammatory cytokine mRNA levels in the jejunum, respectively. Through in silico network analysis, we predicted the mechanisms underlying BJIT-mediated regulation of radiation-induced intestinal injury. BJIT reduced the level of apoptosis in the jejunal crypts 12 h post 5-Gy irradiation. Histological assessment revealed intestinal morphological changes in irradiated mice 3.5 days post 13-Gy irradiation. Furthermore, BJIT decreased inflammatory cytokine levels following radiation exposure. Apoptosis, TNF, p53, VEGF, toll-like receptor, PPAR, PI3K-Akt, and MAPK signaling pathways, as well as inflammatory bowel disease (IBD), were found to be linked to the radioprotective effects of BJIT against intestinal injury. According to our results, BJIT exerted its potential protective effects by attenuating histopathological changes in jejunal crypts and suppressing inflammatory mediator levels. Therefore, BJIT is a potential therapeutic agent that can treat radiation-induced intestinal injury and its associated symptoms.

[PMID: 36275647 PMCID: PMC9583272 DOI: 10.3389/fimmu.2022.1008047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 09/14/2022] [Indexed: 11/13/2022] Open
Abstract
Alarmins exist outside cells and are early warning signals to the immune system; as such, alarmin receptors are widely distributed on various immune cells. Alarmins, proinflammatory molecular patterns associated with tissue damage, are usually released into the extracellular space, where they induce immune responses and participate in the damage and repair processes of mucosal diseases.In the stomach, gastric alarmin release has been shown to be involved in gastric mucosal inflammation, antibacterial defense, adaptive immunity, and wound healing; moreover, this release causes damage and results in the development of gastric mucosal diseases, including various types of gastritis, ulcers, and gastric cancer. Therefore, it is necessary to understand the role of alarmins in gastric mucosal diseases. This review focuses on the contribution of alarmins, including IL33, HMGB1, defensins and cathelicidins, to the gastric mucosal barrier and their role in gastric mucosal diseases. Here, we offer a new perspective on the prevention and treatment of gastric mucosal diseases.

Abstract
BACKGROUND Anorexia and atopic dermatitis (AD) are highly prevalent diseases, and the herbal medicine Bojungikgi-tang (BJT) has been frequently used for the treatment of both anorexia and AD. However, no study has simultaneously evaluated the effects of BJT for both anorexia and AD. METHODS A prospective, randomized, usual care-controlled, assessor-blinded. parallel, pilot clinical trial has been designed to explore the feasibility, preliminary effectiveness, and safety of BJT for the treatment of anorexic patients with AD. Forty anorexic patients with AD will be randomly assigned (1:1) to BJT or the usual care group. The BJT group will be administered BJT granules twice a day for 8 weeks and followed up for 4 weeks whereas the usual care group will not receive BJT granules. All participants in both groups will be provided with over-the-counter topical corticosteroids as a relief drug. Data will be collected at baseline and at 4, 8, and 12 weeks after randomization. The primary outcome is the score on the anorexia visual analog scale at 8 weeks post-treatment. The secondary outcomes include body weight, body fat percentage, body fat mass, skeletal muscle mass, SCORing of Atopic Dermatitis index, Validated Investigator Global Assessment scale for Atopic Dermatitis, Dermatology Life Quality Index, EuroQoL 5 Dimension 5 Level, deficiency and excess pattern identification questionnaire, total immunoglobulin E, eosinophil count, and frequency and amount of use of topical corticosteroids. Adverse events and laboratory test results will be monitored to assess safety. Fecal samples to check for gut microbiome changes and blood samples to check immune and metabolic markers will be collected before and after taking BJT. DISCUSSION This is the first trial that explores the preliminary effectiveness and safety of BJT for the treatment of anorexic patients with AD. The results of this pilot study will provide the basic evidence for large-scale, confirmatory, multicenter, high-quality clinical trials.

Abstract
Cisplatin is a well-known chemotherapeutic agent used to treat various types of cancers; however, it can also induce anorexia, which results in reduced food intake, loss of body weight, and lower quality of life. Although drugs such as megestrol acetate and cyproheptadine are used to decrease this severe feeding disorder, they can also induce side effects, such as diarrhea and somnolence, which limit their widespread use. Various types of herbal medicines have long been used to prevent and treat numerous gastrointestinal tract diseases; however, to date, no study has been conducted to analyze and summarize their effects on cisplatin-induced anorexia. In this paper, we analyze 12 animal studies that used either a single herbal medicine extract or mixtures thereof to decrease cisplatin-induced anorexia. Among the herbal medicines, Ginseng Radix was the most used, as it was included in seven studies, whereas both Glycyrrhizae Radix et Rhizoma and Angelicae Gigantis Radix were used in four studies. As for the mechanisms of action, the roles of serotonin and its receptors, cytokines, white blood cells, ghrelin, and leptin were investigated. Based on these results, we suggest that herbal medicines could be considered a useful treatment method for cisplatin-induced anorexia.

[PMID: 33025599 DOI: 10.1111/jfbc.13510] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 09/10/2020] [Accepted: 09/19/2020] [Indexed: 12/17/2022]
Abstract
Pneumonia refers to a death-causing infection. Astragali Radix (AR) and Atractylodis Macrocephalae Rhizoma (AMR) are widely used as traditional tonic and promising edible immunomodulatory herbal medicine, but the systemic mechanism is not well understood. Therefore, a strategy based on network pharmacology and molecular docking was designed to explore the systemic mechanism of AR-AMR acting on pneumonia. After a series of bioinformatics assays, seven kernel targets were obtained, including TNF, IL6, IFNG, IL1B, IL10, IL4, and TLR9. And seven key compounds were identified as the synergy components of AR-AMR acting on pneumonia, the four key compounds belonging to AR were (3R)-3-(2-hydroxy-3,4-dimethoxyphenyl)-7-chromanol, formononetin, quercetin, and kaempferol, the three key compounds belonging to AMR were atractylone, 14-acetyl-12-senecioyl-2E, 8E, 10E-atractylentriol, and α-Amyrin. The crucial pathways were mainly related to three modules, including immune diseases, infectious disease, and organismal systems. Collectively, these observations strongly suggest that the molecular mechanisms of AR-AMR regulating pneumonia were closely related to the correlation between inflammation and immune response. PRACTICAL APPLICATIONS: Astragali radix and Atractylodis macrocephalae rhizoma can be used as "medicine-food homology" for dietary supplement. AR and AMR are widely used as a traditional tonic and promising edible immunomodulatory herbal medicine. The AR-AMR herb pairs are used for compatibility many times in the recommended prescriptions in COVID-19 develop pneumonia in China. However, the ingredients and mechanisms of AR-AMR acting on Pneumonia via immunomodulation are unclear. In this paper, bioinformatics and network biology were used to systematically explore the mechanisms of the AR-AMR herb pairs in treatment of pneumonia, and further analyze the correlation mechanism between it and COVID-19 develop pneumonia. To sum up, our study reveals the interrelationships between components, targets, and corresponding biological processes of AR-AMR acting on pneumonia. Understanding these relationships may provide guidance and theoretical basis for the further application of AR-AMR herb pairs.

Abstract
Gastric ulcer is a widespread inflammatory disease with high socio-economic burden. C-phycocyanin is one of the active constituents of Spirulina microalgae, and although it is well known for its antioxidant and anti-inflammatory properties, its protective effects against gastric ulcer have not yet been identified. High-mobility group box 1 (HMGB1) is a nuclear protein that, once secreted extracellularly, initiates several inflammatory reactions, and it is involved in the pathogenesis of gastric ulcer. The aim of the present study was to investigate the anti-inflammatory and anti-ulcerogenic effects of C-phycocyanin against ethanol-induced gastric ulcer targeting HMGB1/NLRP3/NF-κB pathway. Ulcer induction showed increase in HMGB1 expression through activation of nucleotide-binding domain and leucine-rich repeat-containing protein 3 (NLRP3) inflammasome and nuclear factor kappa p65 (NF-κB p65). Moreover, oxidative stress and inflammatory markers were elevated in the ulcer-treated group compared to the normal control group. However, pre-treatment with C-phycocyanin significantly reduced HMGB1 expression via suppression of NLRP3/NF-κB, oxidative markers, IL-1β, tumour necrosis factor-α (TNF-α) and ulcer index value. These results were consistent with histopathological and immunohistochemistry examination. Thus, C-phycocyanin is a potential therapeutic strategy with anti-inflammatory and anti-ulcerogenic effects against ethanol-induced gastric ulcer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bojungikki-tang is a traditional herbal medicine used to boost immunity and reduce fatigue. However, there is not enough scientific evidence about its toxicological safety profile to support its continued clinical application. AIM OF THE STUDY The objective of this study was to investigate the subchronic toxicity profile of Bojungikki-tang water extract (BITW) in Sprague Dawley rats who were exposed to it in multiple doses and various concentrations. MATERIALS AND METHODS BITW was administered to rats orally, once daily at doses of 0, 500, 1000, or 2000 mg/kg/day for 13 weeks. We checked toxicological parameters including general observations, organ/body weights, food consumption, ophthalmological signs, hematological and serum biochemical values, urinalysis values and histopathological findings. RESULTS The 13 week repeated oral administration of BITW to rats at doses at doses levels of less than or equal to 2000 mg/kg/day caused no significant toxicological changes and only minor nonsignificant changes. CONCLUSIONS Our findings indicate that administration of BITW for up to 13 weeks may be safe and nontoxic, with a no-observed-adverse-effect-level of >2000 mg/kg/day for both male and female rats.

Abstract
Background Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disease that is characterized by selective motor neuron cell death in the motor cortex, brainstem, and spinal cord. Two drugs for ALS, riluzole and edaravone, have been approved by FDA for the treatment of ALS patients. However, they have many side effects, and riluzole extends the patient's life by only 2-3 months. Therefore, ALS patients seek an effective therapy for treating the symptoms or delaying the progression of ALS. Based on this, we review the effects of complementary and alternative medicine (CAM) in ALS animals or patients to verify the efficacy of CAM in incurable diseases. For this review, we searched published papers focusing on the effect of CAM in pre-clinical and clinical study in ALS. Methods The search keywords included amyotrophic lateral sclerosis, acupuncture, herbal medicine, Traditional Chinese medicine, CAM, animals, and clinical study through electronic databases PubMed and Google Scholar from their inception until March 2019. Results In the ALS animal model, CAM modulated the immune system to increase motor function by reducing the expression levels of neuroinflammatory proteins in the spinal cord. Besides this, ALS patients treated with herbal medicine showed improved disease symptoms, but clinical trials with larger sample sizes are needed to develop a treatment with this herbal medicine. Conclusion This review shows that CAM may be useful for ALS treatment, but more evidence regarding the efficacy and molecular mechanisms is required to establish CAM as a good therapy for the treatment of ALS patients.

[PMID: 30544702 PMCID: PMC6316759 DOI: 10.3390/nu10121952] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 12/07/2018] [Accepted: 12/07/2018] [Indexed: 12/27/2022] Open
Abstract
Bojungikgi-tang (BJIGT; Bu Zhong Yi Qi Tang in China, Hochuekkito in Japan) is a traditional Oriental herbal formula comprised of eight medicinal herbs that has long been used for the treatment of digestive disorders. A recent clinical study from South Korea reported that BJIGT-gamibang administration may be effective in treating dementia. We aimed to establish scientific evidence for the anti-dementia effects of BJIGT using in vitro and in vivo experimental models. We measured amyloid- β (Aβ) aggregation, β-secretase (BACE), and antioxidant activity in a cell free system. Neuroprotective effects were assessed using CCK-8. Imprinting control region (ICR) mice were divided into the following six groups: Normal control, Aβ-injected, Aβ-injection + oral BJIGT gavage (200, 400, or 800 mg/kg/day), and Aβ-injection + oral morin administration (10 mg/kg/day). Subsequently, behavioral evaluations were conducted and brain samples were collected from all the animals and assessed. BJIGT enhanced inhibition of Aβ aggregation and BACE activity in vivo, as well as antioxidant activity in in vitro, cell-free systems. BJIGT also exerted neuroprotective effects in a hydroperoxide (H₂O₂)-induced damaged HT22 hippocampal cell line model. In addition, BJIGT administration significantly ameliorated cognitive impairments in Aβ-injected mice, as assessed by the passive avoidance and Y-maze tests. Furthermore, BJIGT treatment suppressed Aβ aggregation and expression, as well as expression of Aβ, NeuN, and brain-derived neurotrophic factor (BDNF) in the hippocampi of Aβ-injected mice. Overall, our results demonstrate that, with further testing in clinical populations, BJIGT may have great utility for the treatment of dementia and especially Alzheimer's disease.

Abstract
In the present study, Bojungikgi-tang (BJIKT: Buzhongyiqi-tang, Hochuekki-to) and Palmijihwang-hwan (PMJHH: Baweidìhuang-wan, Hachimijio-gan), traditional herbal formulas, investigated anti-inflammatory efficacies in murine macrophage cell line and the influence on the activities of drug-metabolizing enzymes (DMEs). The anti-inflammatory potentials of the herbal formulas were evaluated to inhibit the production of the inflammatory mediators and cytokines and the protein expression of inducible nitric oxide and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-treated RAW 264.7 cells. The activities of the major human DMEs, cytochrome P450 isozymes (CYP450s) and UDP-glucuronosyltransferase isozymes (UGTs), were measured by in vitro enzyme assay systems. BJIKT and PMJHH significantly suppressed the prostaglandin E2 (PGE2) production (IC50 = 317.3 and 282.2 μg/mL, respectively) and the protein expression of COX-2 in LPS-treated RAW264.7 cells. On the human microsomal DMEs, BJIKT inhibited the activities of CYP1A2 (IC50 = 535.05 μg/mL), CYP2B6 (IC50 > 1000 μg/mL), CYP2C9 (IC50 = 800.78 μg/mL), CYP2C19 (IC50 = 563.11 μg/mL), CYP2D6 (IC50 > 1000 μg/mL), CYP2E1 (IC50 > 1000 μg/mL), CYP3A4 (IC50 = 879.60 μg/mL), UGT1A1 (IC50 > 1000 μg/mL), and UGT1A4 (IC50 > 1000 μg/mL), but it showed no inhibition of the UGT2B7 activity at doses less than 1000 μg/mL. PMJHH inhibited the CYP2D6 activity (IC50 = 280.89 μg/mL), but IC50 values of PMJHH exceeded 1000 μg/mL on the activities of CYP1A2, CYP2C19, CYP2E1, and CYP3A4. At concentrations less than 1000 μg/mL, PMJHH did not affect the activities of CYP2B6, CYP2C9, UGT1A1, UGT1A4, and UGT2B7. The results indicate that both BJIKT and PMJHH may be potential candidates to prevent and treat PGE2- and COX-2-mediated inflammatory diseases. In addition, this study will expand current knowledge about herb-drug interactions by BJIKT and PMJHH.

Abstract
Amyotrophic lateral sclerosis (ALS) is a motor neuron disease characterized by progressive motor function impairment, dysphagia, and respiratory failure. Owing to the complexity of its pathogenic mechanisms, an effective therapy for ALS is lacking. Herbal medicines with multiple targets have good efficacy and low adverse reactions for the treatment of neurodegenerative diseases. In this study, the effects of Bojungikgi-tang (BJIGT), an herbal medicine with eight component herbs, on muscle and spinal cord function were evaluated in an ALS animal model. Animals were randomly divided into three groups: a non-transgenic group (nTg, n = 24), a hSOD1G93A transgenic group (Tg, n = 24), and a hSOD1G93A transgenic group in which 8-week-old mice were orally administered BJIGT (1 mg/g) once daily for 6 weeks (Tg+BJIGT, n = 24). The effects of BJIGT were evaluated using a rotarod test, foot-printing, and survival analyses based on Kaplan-Meier survival curves. To determine the biological mechanism underlying the effects of BJIGT in hSOD1G93A mice, western blotting, transmission electron microscopy, and Bungarotoxin staining were used. BJIGT improved motor function and extended the survival duration of hSOD1G93A mice. In addition, BJIGT had protective effects, including anti-oxidative and anti-inflammatory effects, in both the spinal cord and muscle of hSOD1G93A mice. Our results demonstrated that BJIGT causes muscle atrophy and the denervation of neuromuscular junctions in the gastrocnemius of hSOD1G93A mice. The components of BJIGT may alleviate the symptoms of ALS via different mechanisms, and accordingly, BJIGT treatment may be an effective therapeutic approach.

Abstract
Historically, traditional herbal medicines (THMs) have been the conventional treatment strategy in the Korean medical system for treating many diseases. However, THMs have rarely been used to treat hypertension, and moreover few studies have investigated the interaction of blood pressure with the coadministration of synthetic antihypertensives. We aimed to evaluate the vasorelaxant and hypotensive effects of the traditional herbal prescription Cheonwangbosimdan (CWBSD; "Tianwangbuxindan" in Chinese) and the combination of CWBSD with amlodipine. CWBSD was extracted with distilled water at 100°C for 2 h. To investigate vasorelaxant activities, CWBSD with amlodipine (10 μg/ml) was added cumulatively (10-1,000 μg/ml) to isolated rat aortic rings precontracted using phenylephrine or potassium chloride in organ chambers. To investigate hypotensive effects, CWBSD (2,476 mg/kg) was orally administered with or without amlodipine (5 mg/kg) to spontaneously hypertensive rats (SHRs). CWBSD increased the relaxation of rat aortic rings induced by amlodipine (P < 0.01). In vivo, CWBSD coadministration with amlodipine also significantly decreased the blood pressure of SHRs compared to the amlodipine-treated group. These results suggested that CWBSD could be a useful herbal prescription to treat hypertension and we recommend establishing guidelines for the use of herbal medicines in conjunction with antihypertensive drugs, including amlodipine.

Abstract
Traditional herbal medicines have been used for centuries in Asian countries. However, recent studies have led to increasing concerns about the safety and toxicity of herbal prescriptions. Bojungikgi-tang (BJIGT), a herbal decoction, has been used in Korea to improve physical strength. To establish the safety information, BJIGT water extract was evaluated in a 4-week repeated-dose oral toxicity test in Crl:CD Sprague Dawley rats. BJIGT was orally administered in daily doses of 0, 500, 1000, and 2000 mg/kg/day for 4 weeks via oral gavage in male and female rats. We examined the mortality, clinical signs, body weight change, food intake, organ weights, hematology, serum biochemistry, and urinalysis parameters. No significant changes were observed in mortality, clinical sings, body weight, food intake, organ weights, hematology, serum biochemistry, and urinalysis parameters between the control group and the BJIGT-treated groups in the rats of both sexes. The results indicate that BJIGT did not induce toxic effects at a dose level up to 2000 mg/kg in rats. Thus, this concentration is considered the nonobservable effect dose in rats and is appropriate for a 13-week subchronic toxicity study.

Abstract
Cannabinoid type 2 (CB2) receptors are distributed in central and peripheral tissues, including immunocytes and the gastrointestinal (GI) tract, suggesting that CB2 receptor agonists represent potential therapeutics in GI inflammatory states. In this study, we investigated the effect of highly selective CB2 agonist, A836339, on the development of gastric lesions. We used two models of gastric ulcer (GU) induced by ethanol (EtOH) and diclofenac. To confirm the involvement of CB2 receptors, a selective CB2 antagonist, AM630 was used. Clinical parameters for gastroprotection were assessed based on inhibition of the gastric lesion area. To investigate the anti-inflammatory effect of A836339, the expression of TNF-α and IL-1β was assessed. To establish the mechanism of gastroprotective action, catalase (CAT), superoxide dismutase (SOD) activity and H2O2 and glutathione (GSH) levels were measured. Moreover, expression of CB2 and cyclooxygenase-2 (COX-2) was characterized using immunohistochemistry (IHC). A836339 reduced ulcer index in a dose-dependent manner in both EtOH- and diclofenac-induced GU models. This effect was reversed by the CB2 antagonist AM630. Administration of A836339 reduced TNF-α and IL-1β levels in gastric tissue. Furthermore, A836339 exhibited potent anti-oxidant activity, as demonstrated by reduced H2O2 levels and increased CAT and SOD activities. IHC studies revealed a co-localization of CB2 receptors and COX-2 in the gastric tissue. Activation of CB2 receptors exhibited gastroprotective effect through enhancement of anti-oxidative pathways in the stomach. Activation of CB2 receptors may thus become a novel therapeutic approach in the treatment of GU.

Abstract
A liquid chromatography coupled with electrospray ionization mass spectrometry method was developed and validated for simultaneous determination of seven bioactive constituents including astragaloside IV, calycosin, glycyrrhizic acid, enoxolone, saikosaponin D, ferulic acid and hesperiden in rats' various tissues using diclofenac as the internal standard (IS). Biological samples were pretreated by protein precipitation with acetonitrile. The chromatographic separation was carried out on a C18 column with a gradient mobile phase consisting of acetonitrile and water (containing 0.1% formic acid and 4mM ammonium acetate). All analytes and IS were quantitated through electrospray ionization in negative ion multiple reaction monitoring mode. The mass transitions were as follows: m/z 829.7→783.3 for astragaloside IV, m/z 283.3→267.7 for calycosin, m/z 821.6→350.0 for glycyrrhizic acid, m/z 469.9→425.2 for enoxolone, m/z 825.7→779.6 for saikosaponin D, m/z 192.5→133.9 for ferulic acid, m/z 609.1→301.0 for hesperiden and m/z 293.6→249.9 for the IS, respectively. The lower limits of quantification for the seven analytes in different rat tissues were 0.2-20ng/mL. Bu-zhong-yi-qi-tang (Hochuekkito in Japan, Bojungikki-tang in Korea) is one of the most frequently prescribed traditional herbal formulas used in Korea, Japan, and China to treat gastrointestinal diseases, cancer and chronic fatigue syndrome. The validated method was successfully applied to a tissue distribution study of the seven components in rat tissue after oral administration of Bu-zhong-yi-qi-tang concentrated granule. The results of the tissue distribution study showed that the high concentration of seven components were mainly in the gastrointestinal tract.

Syzygium aromaticum water extract attenuates ethanol‑induced gastric injury through antioxidant effects in rats. Mol Med Rep 2016; 14:361-6.

Abstract
The aim of the present study was to investigate whether Syzygium aromaticum water extract (SAWE) has a protective effect against ethanol‑induced gastric injury in rats. Acute gastric injury was induced via intragastric administration of absolute ethanol at a dose of 5 ml/kg. SAWE (250 or 500 mg/kg/day) or cimetidine (100 mg/kg/day), which was used as a positive control, were administered to the rats 2 h prior to ethanol administration for 3 days. All rats were sacrificed 24 h following the final ethanol administration. To examine whether SAWE has a gastroprotective effect, assays were performed to assess the contents of malondialdehyde (MDA) and glutathione (GSH), the activities of catalase, glutathione‑S‑transferase and superoxide dismutase, and an immune-linked immunosorbent assay was performed for prostaglandin E2 (PGE2) production in gastric tissues by hematoxylin and eosin and periodic acid-Schiff staining. Histological assessment of the gastric wall was performed. Compared with ethanol treatment alone, treatment with SAWE at a dose of 250 mg/kg/day significantly decreased the gastric MDA content and increased the GSH content, catalase activity, and production of gastric PGE2. Histological assessment showed that SAWE attenuated inflammatory cell infiltration and the loss of epithelial cells. These findings suggested that SAWE protected against ethanol‑induced gastric mucosal injury in the rats. These effects appeared to be associated with antioxidant activity, activation of the production of PGE2, suppression of inflammatory cell infiltration and loss of epithelial cells in the gastric mucosa. Collectively, SAWE may be beneficial in the prevention of gastric disease associated to oxidative stress.

Abstract
Intestinal mucositis is a serious toxic side effect of 5-fluorouracil (5-FU) treatment. Bu-Zhong-Yi-Qi decoction (BZYQD), a water extract of Chinese traditional herbal medicine, is widely used in chemotherapy in Asia as an alternative treatment to reduce the side effects of chemotherapy. However, the mechanism is unknown. To evaluate its mechanism, we investigated the effect of BZYQD on 5-FU-induced intestinal mucositis in mice, especially with regard to apoptosis in the intestinal mucosal epithelia. In the present study, mice were divided into three groups: control, 5-FU, and 5-FU + BZYQD. Mice in the 5-FU and 5-FU + BZYQD groups were administered 5-FU (100 mg/kg/day, intraperitoneally) for 6 days, and the mice in the latter group were given BZYQD (8 g/kg/day, intragastrically) beginning 4 days before 5-FU and continuing until the termination of the experiment. Loss in body weight and diarrhea during the 5-FU treatment were significantly attenuated by administration of BZYQD. The morphological signs of intestinal damage, including shortened villi height, crypt destruction, apoptosis, and necrosis, in intestinal mucosal epithelia were also reversed, accompanied by reduced neutrophil infiltration, nitrite levels, and inflammatory factors (tumor necrosis factor α and interleukin 1β) and increased levels of reduced glutathione. These results suggest that BZYQD inhibits 5-FU-induced intestinal mucositis, and this effect may be due to the reduction in apoptosis and necrosis in intestinal mucosal epithelia via the suppression of inflammatory cytokine upregulation. In conclusion, inhibiting cytokine-mediated apoptosis or necrosis can be the molecular mechanism by which BZYQD reduces the gastrointestinal side effects of cancer chemotherapy.

Abstract
Curcuma aromatica is an herbal medicine and traditionally used for the treatment of various diseases in Asia. We investigated the effects of C. aromatica water extract (CAW) in the stomach of rats with ethanol-induced gastritis. Gastritis was induced in rats by intragastric administration of 5 mL/kg body weight of absolute ethanol. The CAW groups were given 250 or 500 mg of extract/kg 2 h before administration of ethanol, respectively. To determine the antioxidant effects of CAW, we determined the level of lipid peroxidation, the level of reduced glutathione (GSH), the activities of catalase, degree of inflammation, and mucus production in the stomach. CAW reduced ethanol-induced inflammation and loss of epithelial cells and increased the mucus production in the stomach. CAW reduced the increase in lipid peroxidation associated with ethanol-induced gastritis (250 and 500 mg/kg, p < 0.01, resp.) and increased mucosal GSH content (500 mg/kg, p < 0.01) and the activity of catalase (250 and 500 mg/kg, p < 0.01, resp.). CAW increased the production of prostaglandin E2. These findings suggest that CAW protects against ethanol-induced gastric mucosa injury by increasing antioxidant status. We suggest that CAW could be developed for the treatment of gastritis induced by alcohol.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Decoctions prepared from the bark of Margaritaria discoidea (Baill.) G. L. Webster (Euphorbiaceae) are used in Nigeria and other parts of West Africa in the treatment of wounds and ulcers. The study was conducted to investigate the gastric ulcer protective effect of ethanolic stem bark extract of M. discoidea in rats. MATERIALS AND METHODS Antiulcer assays were performed using ethanol, indomethacin and pylorus ligation-induced ulcer models at the dose of 50, 100 and 150 mg/kg, p.o. The antioxidant effect of the extract was evaluated in vitro and by studying its effect on antioxidant enzymes (superoxide dismutase, catalase, and reduced glutathione) and lipid peroxidation in the stomach tissue of rats in ethanol-induced model. Solvent fractions (hexane, dichloromethane, ethyl acetate, butanol and aqueous) from the crude extract were investigated for antiulcerogenic effects in ethanol-induced ulcer model at the dose of 150 mg/kg. GC-MS analysis of the active hexane fraction was also carried out. RESULTS The extract significantly (P<0.05) reduced gastric lesion in ethanol and indomethacin-induced ulcer models. The extract had significant influence on in vivo antioxidant status in ethanol-induced model. In pylorus ligation-induced model, only the dose of 150 mg/kg showed significant reduction (88.89%, P<0.05) of ulcer lesions. There was no significant reduction in the gastric juice volume and total acidity. The solvent fractions showed ulcer inhibition in varying degrees but significance (P<0.01) was only observed in the hexane fraction. Ethyl esters of palmitic and linoleic acids were found as the major compounds in the GC-MS analysis of the hexane fraction. CONCLUSION Our results suggest that M. discoidea possesses gastroprotective activity possibly mediated through antioxidant mechanism. The data obtained in this study provide some support to the traditional use of M. discoidea in the treatment of gastric ulcer.

Antiulcerogenic Activity and Toxicity of Bauhinia holophylla Hydroalcoholic Extract. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:439506. [PMID: 25954316 PMCID: PMC4410539 DOI: 10.1155/2015/439506] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2014] [Revised: 02/12/2015] [Accepted: 03/10/2015] [Indexed: 12/14/2022]
Abstract
Several species of Bauhinia are used in traditional medicine for the treatment of gastrointestinal diseases, diabetes, and inflammation, among other conditions. The aim of this study was to investigate the antiulcer effect of a hydroalcoholic extract from the leaves of B. holophylla. The chemical profile of the extract was determined by HPLC-PAD-ESI-IT-MS. A dose-effect relation was constructed using the ethanol-induced gastric ulcer model in male Wistar rats. Histological analyses and studies of antioxidant and anti-inflammatory activities were performed in stomach samples. The involvement of SH compounds, NO, K+ATP channels, and α2-adrenergic receptors in the gastroprotective effect was evaluated. A toxicity study was performed with a single oral dose of 5000 mg/kg. The extract was composed mainly of cyanoglucoside and flavonol-O-glycosides derivatives of quercetin and myricetin. SH compounds, NO release, K+ATP channel activation, and presynaptic α2-adrenergic receptor stimulation each proved to be involved in the antiulcer effect. The levels of GSH and activity of GR and GPx were increased, and the levels of TNF-α, IL-6 and IL-10 were modulated. There was an antidiarrheal effect and there were no signs of toxicity. B. holophylla presents antiulcer activity mainly by decreasing oxidative stress and attenuating the inflammatory response, without inducing side effects.

Abstract
Background Paclitaxel induced fatigue still remains underrecognized and undertreated, partly because of limited understanding of its pathophysiology and lack of effective treatments. This study is aim to evaluate the anti-fatigue effects and mechanism of Bu-Zhong-Yi-Qi pill in murine 4 T1 breast cancer mice were treated with paclitaxel. Methods Breast cancer mice established with murine 4 T1 cells were randomly and repectively divided into five groups: negative control group (NC), tumor control group (TC), paclitaxel group (PTX), Bu-Zhong-Yi-Qi pill group (BZYQ) and Bu-Zhong-Yi-Qi pill plus paclitaxel group (BZYQ + PTX). The mice were administered for 21 days. During this period, the tumor volume, body weight and the weight-loaded swimming time were measured. After the last administration, all mice were sacrificed, weighted the tumor, measured immune cell cytokines and oxidative stress indicator. The remaining 10 mice in each group were observed for survival analysis. Results Treatments with BZYQ + PTX and PTX significantly reduced the rates of tumor volume in comparison with TC starting on the 9th day and the 18th day respectively (P < 0.05-0.01), and presented decreased tumor weight compared to TC (P < 0.05-0.01). Compared with mice in TC group, the median survival time and the average survival time in BZYQ + PTX group, BZYQ group and PTX group were significantly prolonged (P < 0.05-0.01). The swimming time of the BZYQ + PTX group gradually increased, which is longer than the PTX group on Day 14 and Day 21 (P < 0.01). The level of TNF-α was lower in BZYQ + PTX group than PTX group (P < 0.01). The level of SOD activity in BZYQ + PTX group was lower than the NC group (P <0.01), but much higher than the PTX group (P < 0.01). The level of MDA of BZYQ + PTX group was higher than the NC group (P < 0.01), but significant lower than the PTX group (P < 0.01). Conclusions BZYQ has the potential of alleviating paclitaxel chemotherapy-related fatigue in 4 T1 breast cancer mice by reducing the serum levels of TNF-α and modulating the level of MDA and the SOD activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bu-zhong-yi-qi-tang (BT) is a classical formula for the treatment of spleen-qi descending, visceroptosis with hyposplenic qi, uterine prolapse, and rectal prolapse due to chronic diarrhea in traditional Chinese medicine (TCM) and has been identified as an effective drug for the treatment of TCM spleen-qi deficiency in clinical practice. The present study aimed to investigate the restorative effect and the potential mechanisms of Bu-zhong-yi-qi-tang in a rat spleen-qi deficiency model using (1)H-NMR-based metabonomics. MATERIALS AND METHODS The rat spleen-qi deficiency model was established as follows: oral administration of Radix Rhei extract (equivalent to 10g/kg body weight of the crude drug), loaded swimming, and starvation for 24h. Each of these treatments was administered consecutively every three days. Sixty male SD rats were randomly divided into five groups, and three of the groups received a different oral dose of the aqueous extract of Bu-zhong-yi-qi-tang during the last seven days of the three-week experimental period. The body weight and motor behavior of the rats were measured and recorded once a week. The endogenous metabolites in the plasma were analyzed using NMR in conjunction with multivariate and statistical techniques. In addition, the liver and spleen were removed and weighed. RESULTS All of the rats in the spleen-qi deficiency group presented pasty loose stools, inactiveness, grouping, a decrease in swimming endurance, and lackluster, loose, and disorderly behavior in addition to a significant decrease in body weight, spleen weight, and liver weight. In contrast, the abovementioned demonstrations were reversed to a certain extent in the rats treated with Bu-zhong-yi-qi-tang compared with the model group (p<0.05, p<0.01). A significant separation was determined between the control and model groups in the PCA score plot, which indicates that the spleen-qi deficiency model was successfully duplicated. The changes in the levels of endogenous metabolites in the plasma included lower levels of valine, leucine, and O-acetyl-glycoprotein and a higher concentration of lactate in the spleen-qi deficiency group compared with the control group. Treatment with Bu-zhong-yi-qi-tang at least partially returned the levels of these metabolites to the normal levels. CONCLUSIONS The restorative effects of Bu-zhong-yi-qi-tang in rats with spleen-qi deficiency were confirmed, and four endogenous metabolites were identified as potential biomarkers of the symptoms of spleen-qi deficiency and most likely play roles in the changes observed in certain metabolic pathways, such as the energy, protein, and glycolytic metabolisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Castilleja tenuiflora Benth. (Orobanchaceae) is a perennial shrub used since the 16(th) century in Mexican traditional medicine for the treatment of a number of health disorders including inflammation, stomach pain and tumors. The aim of the present study was to evaluate the cytotoxic, anti-inflammatory and anti-ulcerogenic activities of ethyl acetate (EaE), methanol (ME) and aqueous extracts (AE) of Castilleja tenuiflora wild grown (CtW) and in vitro plants (CtIv). MATERIAL AND METHOD Phytochemical analysis of the phenylethanoid glycoside (PhG) and iridoid glycoside (IG) components was carried out by chromatographic methods. In vitro cytotoxic activity of the extracts was evaluated in the following four carcinoma cell lines: colon (HF-6), breast (MCF-7), prostate (PC-3), and nasopharyngeal (KB). The topical anti-inflammatory activity was evaluated in mouse ear edema induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). Anti-ulcerogenic activity was evaluated in rats using an absolute ethanol-induced acute gastric ulcer model. RESULTS The main compounds in the extracts were isoverbascoside, verbascoside and aucubin and their concentration depended both on the solvent used and on the plant material origin. None of the extracts showed cytotoxicity against the tested cell lines. In contrast, CtWEaE, CtWAE and CtIvEaE (1.6 mg/ear) showed moderate anti-inflammatory activity similar to dexamethasone (1 mg/ear) with a 38.2, 39.3 and 49.1% decrease of inflammation, respectively. CtWEaE and CtIvEaE (100 mg/kg) showed high anti-ulcerogenic activity with 88.3 and 83.1% inhibition, respectively, compared to famotidine (20 mg/kg, 32.8% inhibition). CONCLUSION Castilleja tenuiflora extracts provided significant gastric protection in an acute ulcer induction model and topical anti-inflammatory activity in a mouse ear edema model. These activities are related to verbascoside and may explain the traditional use of Castilleja tenuiflora in the treatment of anti-inflammatory and gastrointestinal disorders. Cultured Castilleja tenuiflora plants (in vitro) exhibited pharmacological activities and also have the potential to produce bioactive compounds.

Abstract
Background Banhabaekchulchunma-tang (hange-byakujutsu-tenma-to in Japanese and banxia-baizhu-tianma-tang in Chinese) is a mixture of fourteen herbs. It is used traditionally for the treatment of anemia, anorexia, general weakness, and female infertility in China, Japan, and Korea. In this study, we investigated the protective effects of a Banhabaekchulchunma-tang water extract (BCT) against ethanol-induced acute gastric injury in rats. Methods Gastric injury was induced by intragastric administration of 5 mL/kg body weight of absolute ethanol to each rat. The positive control group and the BCT group were given oral doses of omeprazole (50 mg/kg) or BCT (400 mg/kg), respectively, 2 h prior to the administration of absolute ethanol. The stomach of each animal was excised and examined for gastric mucosal lesions. To confirm the protective effects of BCT, we evaluated the degree of lipid peroxidation, the level of reduced glutathione (GSH), and the activities of the antioxidant enzymes catalase, glutathione-S-transferase, glutathione peroxidase, and glutathione reductase in the stomach. In addition, we conducted an acute toxicity study to evaluate the safety of BCT according to OECD guideline. Results BCT reduced ethanol-induced hemorrhage, hyperemia, and loss of epithelial cell in the gastric mucosa. BCT reduced the increased lipid peroxidation associated with ethanol-induced acute gastric lesions, and increased the mucosal GSH content and the activities of antioxidant enzymes. In addition, BCT did not cause any adverse effects at up to 5000 mg/kg. Conclusions These results indicate that BCT protects the gastric mucosa against ethanol-induced gastric injury by increasing the antioxidant status. We suggest that BCT could be developed as an effective drug for the treatment of gastric injury caused by alcohol intake.

Protective effects of the traditional herbal formula oryeongsan water extract on ethanol-induced acute gastric mucosal injury in rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:438191.

Abstract
This study was performed to evaluate the protective effect and safety of Oryeongsan water extract (OSWE) on ethanol-induced acute gastric mucosal injury and an acute toxicity study in rats. Acute gastric lesions were induced via intragastric oral administration of absolute ethanol at a dose of 5 mL/kg. OSWE (100 and 200 mg/kg) was administered to rats 2 h prior to the oral administration of absolute ethanol. The stomach of animal models was opened and gastric mucosal lesions were examined. Gastric mucosal injuries were evaluated by measuring the levels of malondialdehyde (MDA), glutathione (GSH), and the activity of antioxidant enzymes. In the acute toxicity study, no adverse effects of OSWE were observed at doses up to 2000 mg/kg/day. Administration of OSWE reduced the damage by conditioning the gastric mucosa against ethanol-induced acute gastric injury, which included hemorrhage, hyperemia, and loss of epithelial cells. The level of MDA was reduced in OSWE-treated groups compared with the ethanol-induced group. Moreover, the level of GSH and the activity of antioxidant enzymes were significantly increased in the OSWE-treated groups. Our findings suggest that OSWE has a protective effect on the gastric mucosa against ethanol-induced acute gastric injury via the upregulation of antioxidant enzymes.
