In recent years, there has been an increase in the morbidity of gastritis in Korea due to lifestyle factors mostly changes in eating habits and stress. Gastritis is more likely to progress to gastric cancer, and therefore it is important to prevent and manage gastritis through lifestyle adjustment and treatment at an early stage. In this study, cabbage, which was found to be effective in gastritis, was mixed and fermented with other crucifer plants such as kale and broccoli to evaluate the overall efficacy of fermented brassica puree on alcoholic acute gastritis. Based on our results, fermented brassica puree alleviated gastric injury induced by 150 mM HCl/60% ethanol. In addition, it was confirmed that PGE₂, a gastric mucosal protective factor, was increased, and other positive effects such as an increase of MUC1 and regulation of PKC were observed. The results of this study suggest that fermented brassica puree can relieve acute alcoholic gastritis by regulating PGE and the expression of MUC1, a gene related to mucus secretion, and activating PKC, which is related to mucosal cell activity.

Sogunjung-tang (SGJT) is traditional herbal prescriptions used to treat abdominal pain. In this study, we evaluated the effect on inflammation and gastritis through SGJT formulation development. SGJT composition herbal medicine was boiled in water at 95~100℃ for 3 hours and then concentrated. Sogunjung-tang mix soft extract (STM) was prepared using pharmaceutical excipients such as purified water, sodium benzoate, β-cyclodextrin and CMC-Na. Anti-inflammatory experiment was conducted using STM and lipopolysaccharide (LPS) in RAW 264.7 cells. Cell survival was measured by MTT method. Nitric oxide (NO) was measured using griess reagents, and pro inflammatory cytokines were measured by enzyme-linked immunosorbent assay and RT-PCR. Also, we verified STM validity in acute gastritis using the ICR mouse. STM was administered oral for three days. And 150 mM HCl in 60% ethanol was oral administered 0.5 mL one hour after the last drug administration. Mice were sacrificed 1 hour after 150 mM HCl in 60% ethanol administration. The gastric mucosa was visually observed. STM were not toxic in RAW 264.7 cells. Treatment of STM inhibited the production of NO and inflammatory cytokine at the protein and mRNA levels. Also, in the acute gastritis model with the mouse, the treatment of STM improved gastric mucosal bleeding and edema. In summary, it was confirmed that the treatment of STM exerts anti-inflammatory and anti-gastritis effects. Therefore, we suggest that STM may provide a preclinical evidence for the prevention and treatment of inflammatory and gastritis diseases.

Objective: Alcohol is known to cause inflammation in the stomach by decreasing the protective substances of the gastric mucosa and increasing oxidative stress. The purpose of this study was to investigate the anti-inflammatory effect of Artemisiae Argyi Folium extract (AF) on alcohol-induced gastritis. Methods: The total polyphenol and flavonoid contents of AF were confirmed through an in vitro experiment. Radical scavenging activities were confirmed using DPPH and ABTS assays. In vivo experiments were conducted on mice divided into 5 groups (n=8): a normal group (Nor), an alcohol-induced gastritis group (Con), an alcohol-induced gastritis group administered 10 mg/kg sucralfate (SC), an alcohol-induced gastritis group administered 100 mg/kg AF (AFL), and an alcohol-induced gastritis group administered 200 mg/kg AF(AFH). The serum levels of reactive oxygen species (ROS) were determined, and protein expressions were confirmed in gastric tissues. Results: In alcohol-induced gastritis, AF alleviated damage to the gastric mucosa caused by alcohol. AF also decreased the serum ROS levels. Western blots showed that AF decreased the expression of NADPH oxidase and decreased the expression of the NF-κB pathway associated with inflammation. AF also decreased the expression of adhesion molecules and chemokine proteins, and increased the expression of anti-inflammatory proteins. Conclusions: AF not only reduced oxidative stress in alcohol-induced gastritis, but it also relieved gastric mucosal inflammation by regulating the expression of the NF-κB pathway.

Objective : This study was designed to evaluate the protective effect of Rehmanniae Radix Crudus (RC) in 150 mM HCl/ethanol induced acute gastritis mice. Methods : ICR mice were divided into 5 groups (normal group, control group, 10 mg/kg sucralfate treated group, 50 mg/kg RC treated group, 100 mg/kg RC treated group, n=8). Normal group was not take any treatment. Control group induced gastritis 1 hour after ingestion of distilled water. 10 mg/kg sucralfate induced group was induced gastritis 1 hour after ingestion of distilled of sucralfate 10 mg/kg. 50 mg/kg and 100 mg/kg RC treated groups were induced gastritis 1 hour after ingestion of distilled of RC 50 mg/kg and 100 mg/kg. After 1 hour of gastritis induction, removed the stomach tissue. We examined histological observations, oxidative stress biomarkers, antioxidant proteins, inflammatory mediators and cytokines. Results : In this study, the RC treatment group showed gastritis and gastric ulcer inhibition, and the area of injury decreased. The oxidative stress biomarkers such as reactive oxygen species (ROS) and peroxy nitrite ($ONOO^-$) in the serum were reduced in the RC treated group. Inaddition, antioxidant proteins (nuclear factor erythroid 2-related factor 2, Heme oxygenase 1) were increased in RC treated group, and the expression of inflammatory mediators and cytokines induced by nuclear factor-kappa B activation was inhibited. Conclusion : According to the results, RC may have an excellent inhibitory effect on acute gastritis and gastric ulcer.

Cotoneaster mongolicus Pojark. (CM), in the family Rosaceae is an endemic plant to the Mongolian region (its name: Moнroл чapraй). In Mongolia, Cotoneaster species as a crude drug is mainly used for inflammatory diseases, diarrhea, and stomach indigestion. In this study, we evaluated the gastro-protective activity underlying mechanism of CM. For in vivo experiments, mice were divided into 5 groups; normal mice (Normal), gastritis mice (Control), gastritis mice treated with sucralfate 10 mg/kg (SC), gastritis mice treated with CM 100 mg/kg (CML), gastritis mice treated with CM 200 mg/kg (CMH). Gastritis was provoked by HCl/ethanol (60% ethanol in 150 mM HCl). After oral administration of each drug, HCl/ethanol was orally administered 90 mins later to induce gastritis. CM alleviated the damage to the gastric mucosa caused. As a result of confirming the expression of protein in gastric tissue through western blot, CM significantly reduced the expression of NF-κB activated due to gastritis. Also, it significantly modulated the Nrf2-Keap1 pathway. These results indicate that CM not only inhibits the nuclear metastasis of NF-𝛋B but also modulates the Nrf2-Keap1 pathway to relieve inflammation of the gastric mucosa.

Although Korea is the world's No. 1 semiconductor producing country, most studies are conducted with risk assessment for simple material risks due to the closedness of the site for industrial protection. In terms of industrial safety, a monitoring system such as a gas detector to determine the leakage of hazardous substances has been established, but research on effectively discharging harmful gastritis substances in case of leakage has only recently begun. Semiconductor manufacturing facilities (gas boxes) where a large amount of flammable materials are handled are currently being safety managed by using a gas detector and blocking the air inlet. It is difficult to dilute in a short time in case of leakage of flammable substances. Therefore, in this study, based on various criteria, the size of the duct according to the size of the gas box is determined and the appropriate size of the air inlet is studied to minimize the exhaust performance requirement without exposing hazardous chemicals to the outside in the event of a flammable leak. We want to do an optimal exhaust design.

Objective: This study assessed the effectiveness of using Yijung-tang to treat chronic gastritis through a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: The search was conducted using keywords such as "gastritis", "Lizhong", "Yijung", and "Chronic gastritis" on July 31, 2023. A meta-analysis was conducted according to outcome measurements, such as total effective rate (TER), Traditional chinese medicine symptom score (TSS), gastric hormones, and symptom relief time, using the Review Manager website. Results: A total of 11 RCT studies were selected. The treatment group (Yijung-tang-gagam or Yijung-tang-gagam+Western medicine) showed significant improvement effects in terms of TER, TSS, serum gastrointestinal hormones (motilin (MTL), gastrin (GAS), and somatostatin (SS)), and symptom relief time compared to the control group (Western medicine). TER-RR : 1.20, 95% CI : 1.11 to 1.30, P≤0.00001, RR : 1.21, 95% CI : 1.14 to 1.28, P≤0.00001; MTL-MD : 35.99, 95% CI : 30.79 to 41.20, P≤0.00001); GAS-MD : 103.33, 95% CI : 97.62 to 109.04, P≤0.00001); SS : MD : -37.19, 95% CI : -41.75 to -32.64, P≤0.00001; symptom relief time (nausea)-MD : -1.96, 95% CI : -2.47 to -1.45, P≤0.00001; symptom relief time (colic)-MD : -1.75, 95% CI : -2.31 to -1.18, P≤0.00001. Conclusion: This study suggests that Yijung-tang is effective against chronic gastritis. However, the number of studies was insufficient, and the diagnosis and evaluation criteria were not standardized. Furthermore, because of the low quality of the included studies, more clinical studies need to be conducted to increase the possibility of clinical use.

The purpose of this study was to identify the applicability, main compounds, and target genes of Cnidii Fructus (CF) in the treatment of gastritis using network pharmacology. The compounds in CF were searched in Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and a database of medicinal materials and chemical compounds in Northeast Asian traditional medicine (TM-MC). The target gene information of the compounds was collected from pubchem and cross-compared with the gastritis-related target gene information collected from Genecard to derive the target genes. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on the derived target genes. Afterwards, network analysis between compounds and disease target genes was performed using cytoscape. We identified 121 active compounds and 139 target genes associated with gastritis. Pathways derived from the GO biological process and KEGG pathway DB primarily focus on target genes related to inflammation (IL-6, IL-8, TNF production, NF-κB transcription factor activity, and NF-κB signaling pathway) and cell death (PI3K-Akt, FoxO). Major targets for CF treatment of gastritis include TP53, TNF, BCL2, EGFR, NFKB1, ABCB1, PPARG, PTGS2, IL6, IL1B, and SOD1, along with major compounds such as coumarin, osthol, hexadecanoic acid, oleic acid, linoleic acid, and stigmasterol. This study provided CF's applicability for gastritis, related compounds, and target information. Evaluating CF's effectiveness in a preclinical gastritis model suggests its potential use in clinical practice for digestive system diseases.
