Gastroprotective Effect of Myricetin on Ethanol-Induced Acute Gastric Injury in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9968112. [PMID: 34630623 PMCID: PMC8497113 DOI: 10.1155/2021/9968112] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 08/23/2021] [Accepted: 08/25/2021] [Indexed: 01/10/2023]
Abstract
The flavonoid myricetin is abundant in vegetables and has various bioactive properties, including anti-inflammatory and antioxidative activities. In the present study, we explored the effects of myricetin on alcohol-induced gastric ulcer in a rat model. To induce gastric ulcer, absolute ethanol (5 mL/kg body weight) was orally administrated to each rat. The positive control and myricetin-treated groups were given oral doses of omeprazole (20 mg/kg) or myricetin (12 mg/kg), respectively, 1 hour prior to the administration of absolute alcohol. We found that pretreatment with myricetin significantly decreased alcohol-induced gastric ulcer, hemorrhage, hyperemia, and epithelial cell loss in the gastric mucosa. Myricetin pretreatment reduced the level of malondialdehyde (MDA) and increased that of total glutathione (GSSG/GSH) and superoxide dismutase (SOD) in gastric tissues. In addition, it elevated the expression levels of cyclooxygenase-1 (COX-1) and prostaglandin E2 (PGE2) and decreased the phosphorylation of nuclear factor kappa B (NF-κB). Together, these results indicate that myricetin effectively inhibits ethanol-induced acute gastric injury by preventing oxidative damage, stimulating PGE2 production, and inhibiting NF-κB activation. We suggest that myricetin may be an alternative treatment for gastric injury caused by alcohol intake.

[PMID: 33262700 PMCID: PMC7686799 DOI: 10.3389/fphar.2020.526349] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Accepted: 09/09/2020] [Indexed: 12/11/2022] Open
Abstract
Ethanol-induced gastric mucosal injury is a common gastrointestinal disorder. Polysaccharides separated from herbs have been shown to be effective for ethanol-induced gastric mucosal injury, but whether the polysaccharides from Dendrobium officinale Kimura & Migo leaves (LDOP-1) protected mucosa from ethanol-induced injury remains unknown. Thus, the present study carried out gastric mucosal protection and the mechanism of LDOP-1 in vivo and vitro. The chemical composition of LDOP-1 was a heteropolysaccharide comprising mannose, galacturonic acid, glucose, galactose, and arabinose at a molar ratio of 2.0:1.1:0.7:0.5:0.4. Pharmacological results showed that LDOP-1 significantly reduced gastric mucosal injury score and pathological injury, improved antioxidant capacity, reduced the level of reactive oxygen species, and reversed the apoptosis of GES-1 in vivo and vitro. Research showed that LDOP-1 pretreatment upregulated the expression level of p-AMPK, LC3β, HO-1, and Beclin-1; downregulated the expression level of p-mTOR and p62; and reversed the expression level of caspase3, Bax, and Bcl-2. This study was the first to demonstrate that LDOP-1 could protect against ethanol-induced gastric mucosal injury via the AMPK/mTOR signaling pathway in vitro and vivo.

Jin SE, Shin HK, Ha H. Hepatoprotective effects of Gamisoyo-san against acetaminophen-induced liver injuries. Integr Med Res 2020; 10:100466. [PMID: 32904181 PMCID: PMC7452581 DOI: 10.1016/j.imr.2020.100466] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 06/18/2020] [Accepted: 06/24/2020] [Indexed: 02/06/2023] Open
Abstract
Background Acetaminophen (N-acetyl-p-aminophenol, APAP) is a safe and effective analgesic at therapeutic dosage. However, APAP overdose is a major cause of acute liver injury. Gamisoyo-san (GMSYS; Jiaweixiaoyao-san in Chinese, Kamishoyo-san in Japanese), a traditional herbal formula, is used to treat phlegm and cough in Korea. The purpose of this study was to investigate the hepatoprotective effect of GMSYS against APAP-induced liver injury in vitro and in vivo. Methods We evaluated the effect of GMSYS on APAP-induced hepatotoxicity by measuring cell viability in murine BNL CL.2 liver cells. Additionally, BALB/c mice were orally administered with GMSYS once daily for 7 days. Eighteen hours after the last administration, mice were intraperitoneally injected with 200 mg/kg APAP. Plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, hepatic antioxidants, and histological changes were examined. Results Pretreatment with GMSYS attenuated the decrease in cell viability induced by APAP in BNL CL.2 cells. In mice, pre-administration with GMSYS alleviated APAP-induced hepatotoxicity by decreasing plasma ALT and AST activities and hepatic malondialdehyde, and by increasing the total glutathione (GSH)/reduced GSH ratio and the activities of several antioxidants such as superoxide dismutase, catalase, GSH peroxidase, GSH reductase, GSH-S-transferase, and heme oxygenase-1. Conclusion GMSYS has a protective effect against APAP-induced acute liver injury by decreasing plasma transaminases and increasing antioxidants. GMSYS may be an effective candidate for the prevention of acute liver injury.

Abstract
Gastric ulcer is a worldwide disease. Helicobacter pylori is one of the most common chronic bacterial infections that induce chronic inflammation in the gastric mucosa, mediated by an array of pro-and inflammatory cytokines. The aim of this study was to investigate the possible therapeutic effects of Ginkgo biloba extract on gastric ulcer induced by ammonium hydroxide in rats and the potential underlying mechanisms. The study was done on 32 adult male Wistar albino rats, divided equally into 4 groups: normal control, gastric ulcer-induced group using 1 ml of 1% NH4OH orally, ulcer control group; rats received 1% carboxymethyl cellulose daily for 14 days after induction of ulcer and treated rats received orally 200 mg/kg Ginkgo biloba once daily for 14 days after induction of ulcer. The study revealed administration of ammonia showed multiple gastric lesions; edema, hyperemia, hemorrhage, and ulcers with a significant increase in ulcer score, myeloperoxidase (MPO), and interleukin-1β (IL-1β) and a significant decrease in reduced glutathione (GSH), mucus amount, and gastric pH. After the administration of Ginkgo biloba, there was an improvement in gastric lesions, with a significant reduction of ulcer score, MPO, and IL-1β and a significant increase in GSH, mucus content, and gastric pH. Moreover, collagen types I and IV were gradually increased in the treated group.

Abstract
The potential of probiotics for treating ulcerative colitis (UC) has attracted increasing attention. However, more studies are still needed to guide physicians on the proper selection and use of probiotics. Here, we propose that combination of multiple probiotics with different functions can reduce intestinal inflammation. In this study, the effects of probiotics (Lactobacillus reuteri, Bacillus coagulans, Bifidobacterium longum, and Clostridium butyricum) on the physiology and histopathology of colon were evaluated in a dextran sulfate sodium (DSS)-induced colitis mouse model. The combined species, as well as the species individually, were tested and compared with sulfasalazine (SASP) and two Chinese herbal therapies. Results show that the functions of the four probiotic strains were different in regulating intestinal immunity and barrier function. The four-species probiotic cocktail was more effective than the species individually and anti-inflammatory drugs in repairing the dysbiosis of mucosal microbial ecology and reducing intestinal inflammation. The multi-strain probiotic mixture increased the proportion of beneficial bacteria and decreased the proportion of pro-inflammatory bacteria in the colonic mucosa. In addition, probiotic mixture significantly enhanced the expression of IL-10 and intestinal barrier function. These results suggest that a combination of multiple probiotics with different functions has synergistic effects and can restore the balance of interactions between microorganisms and immunological niches.

Abstract
More than 40% dementia patients received traditional Chinese Medicine treatment. However, the prescription pattern of Chinese herbal formulae (CHF) for treating neurocognitive or behavioral disorders in patients with dementia has not been elucidated. This large-scale survey aimed is to evaluate core patterns of CHF and drug-herb concurrent use in patients with dementia.We analyzed patients with a diagnosis of dementia from one million cohorts of the Longitudinal Health Insurance Database in the National Health Insurance Research Database, between 1997 and 2008. Of 18,141 newly diagnosed dementia patients, 3471 patients received CHF for mental and nervous system diseases. There were 13,254 outpatient visits, with 60,968 formulae prescriptions. We calculate the frequency and proportion of combined use, identify drug-herb concurrent usage, and determine core prescription patterns. Also, we drew network graphs of co-prescription pairs which occurred more than 200 times.Chinese medicine prescription patterns changed as dementia progressed.During the first 3 years after the diagnosis of dementia, Jia-Wei-Xiao-Yao-San, Gan-Mai-Da-Zao-Tang, and Ban-Xia-Bai-Zhu-Tian-Ma-Tang were the core CHF prescribed for mental and nervous system disorders. However, during the later stages of dementia, Suan-Zao-Ren-Tang, Gui-Pi-Tang, Jia-Wei-Xiao-Yao-San, and Wen-Dan-Tang were the core CHF prescribed. Benzodiazepines were the most common sedative drugs combined with traditional Chinese formulae.The results of this study suggest that TCM prescription were different in various stages of dementia, and indicated the frequently combined use of the TCM formulae and Benzodiazepines in dementia care.

Abstract
Weaning stress has serious negative effects on piglets' health and the swine industry. Probiotics-fermented Chinese herbal medicines are potential feed additives to ameliorate weaning stress. In this study, the effects of probiotics-fermented Massa Medicata Fermentata (MMFP) on intestinal homeostasis were evaluated in weaning piglets. Dietary supplementation with MMFP promoted the development of the intestinal structure and elevated the concentrations of lactic acid and short-chain fatty acids (SCFAs) in the intestinal contents and antioxidant capacities in serum. MMFP reduced the levels of inflammatory factors in the intestinal mucosa. Microbial community analysis demonstrated that MMFP led to the selective and progressive enrichment of lactic acid- and SCFA-producing bacteria along the gastrointestinal tract, in particular, OTUs corresponding to Lactobacillus, Streptococcus, Acetitomaculum, Roseburia, and Eubacterium xylanophilum group, while MMFP reduced the relative abundance of pathogenic bacteria. On the contrary, antibiotics had negative effects on intestinal histology and increased the relative abundance of pro-inflammatory bacterium, such as Marvinbryantia, Peptococcus, Turicibacter, and Blautia. Correlation analysis reflected that the bacteria enriched in MMFP group were positively correlated with enhanced intestinal homeostasis, which suggested that dietary supplementation with MMFP enhanced host intestinal homeostasis by modulating the composition of gut microbiota and the levels of beneficial SCFAs, thus ameliorating weaning stress in piglets.

Abstract
Acute gastric mucosal injuries are serious clinical problems worldwide and are principally found with different types of stresses in animals. A constant challenge is to find original plant products that can combat stress. In the present study, we examined the effects of big-leaf mulberry extracts on stomach injury, and the activity of nitric oxide synthases (NOS) and total antioxidant activity (TAO) in the gastric mucosae of mice during water immersion and restraint stress (WIRS). Our data showed that WIRS-exposed mice produced several injuries and showed an enhanced iNOS, reduced eNOS activity, and decreased TAO activity in the stomach, whereas pretreatment with big-leaf mulberry extracts increased TAO activitiy. The data from our immunohistochemical study indicated that both iNOS and eNOS were expressed in parietal cells and blood vessels, while nNOS was only weakly expressed in parietal cells. In conclusion, our findings suggested that big-leaf mulberry mitigated WIRS-induced stomach injuries, and NOS signaling may play important roles in the mouse stomach during the recovery process.

Abstract
Objective This aim is to evaluate the effect of Sijunzi decoction (SJZD) treating chronic atrophic gastritis (CAG). Methods We performed searches in seven databases. The randomized controlled trials (RCTs) comparing SJZD with standard medical care or inactive intervention for CAG were enrolled. Combined therapy of SJZD plus conventional therapies compared with conventional therapies alone was also retrieved. The primary outcome included the incidence of gastric cancer and the improvement of atrophy, intestinal metaplasia, and dysplasia based on the gastroscopy and pathology. The secondary outcomes were Helicobacter pylori clearance rate, quality of life, and adverse event/adverse drug reaction. Results Six RCTs met the inclusion criteria. The research quality was low in the trials. For the overall effect rate, pooled analysis from 4 trials showed that modified SJZD plus conventional medications exhibited a significant improvement (OR = 4.86; 95% CI: 2.80 to 8.44; P < 0.00001) and without significant heterogeneity compared with the conventional medications alone. None reported the adverse effect. Conclusions Modified SJZD combined with conventional western medicines appears to have benefits for CAG. Due to the limited number and methodological flaw, the beneficial and harmful effects of SJZD for CAG could not be identified. More high-quality clinical trials are needed to confirm the results.

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
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
Prunella vulgaris L. belongs to the Prunella genus and has been proven effective in the treatment of gastric cancer, however, the therapeutic activity of the endophytic fungi is not yet well understood. The results of the present study suggest that the ethyl acetate extract (S03-EA) of the endophytic fungus XKC-S03, isolated from Prunella vulgaris L. spica, is a potent anticancer agent with the potential to treat gastric cancer. In the present study, the effects of S03-EA on gastric cancer in vitro and in vivo were determined using the 1-(4,5-dimethylthiazol-2-yl)-3,5-diphenylformazan assay and the human gastric cancer SGC 7901 cell xenograft model. The tumor tissue was fixed with 10% formaldehyde solution and the levels of the apoptotic proteins, B-cell lymphoma protein-2 (Bcl-2), Bcl-2-associated X protein (Bax) and pro-angiogenic vascular endothelial growth factor (VEGF), were measured by immunohistochemistry. The results indicated that treating SGC 7901 cells with petroleum ether (S03-PE), ethyl acetate (S03-EA) or dichloromethane (S03-DM) extracts from the XKC-S03 fermentation broth inhibited cell proliferation. S03-EA demonstrated the best activity, with a half maximal inhibitory concentration of 25.89 μg/ml and dose-dependent suppression of the SGC 7901 tumor cells in vivo, without any evident adverse effects. In addition, the 100-mg/kg/day S03-EA-treated tumor tissue revealed a downregulation of Bcl-2 and VEGF expression and an upregulation of Bax expression. In conclusion, the S03-EA extract of XKC-S03, isolated from Prunella vulgaris L. spica, exhibits a growth-suppressive activity on gastric cancer in vitro and in vivo.

Abstract
This study investigated the gastroprotective effects of diallyl disulfide (DADS), a secondary organosulfur compound derived from garlic (Allium sativum L.) on experimental model of ethanol (EtOH)-induced gastric ulcer in rats. The antiulcerogenic activity of DADS was evaluated by gross/histopathological inspection, pro-inflammatory cytokines, and lipid peroxidation with antioxidant enzyme activities in the stomach. DADS (100 mg/kg) was administered by oral gavage 2 h prior to EtOH treatment (5 ml/kg). The animals were killed 1 h after receiving EtOH treatment. Pretreatment with DADS attenuated EtOH-induced gastric mucosal injury, as evidenced by decreased severity of hemorrhagic lesions and gastric ulcer index upon visual inspection. DADS also prevented histopathological alterations and gastric apoptotic changes caused by EtOH. An increase in tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase was observed in the gastric tissues of EtOH-treated rats that coincided with increased serum TNF-α and interleukin 6 levels. In contrast, DADS effectively suppressed production of pro-inflammatory mediators induced by EtOH. Furthermore, DADS prevented the formation of gastric malondialdehyde and the depletion of reduced glutathione content and restored antioxidant enzyme activities, such as catalase, glutathione peroxidase, and glutathione reductase in the gastric tissues of EtOH-treated rats. These results indicate that DADS prevents gastric mucosal damage induced by acute EtOH administration in rats and that the protective effects of DADS may be due to its potent antioxidant and anti-inflammatory activities.
