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.

Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

Objectives : The objective of this study was to examine the effects of P. oleracea into the HCl-ethanol induced gastritis in rats, and to isolate and determine the chemical compounds from P. oleracea. Methods : The rats were orally administered with crude extract or fractions or isolated compounds of P. oleracea 30 mins before the induction of gastric lesion by oral administration of HCl-ethanol. The gastric lesional area was measured using pixel counting software. Then the chemical compounds from P. oleracea was isolated and determined by LC-MS and NMR. Results : The inhibition effect of oral administration of crude extract of P. oleracea at a dose of 500 mg/kg in HCl-ethanol induced gastritis was similar to cimetidine. Then, aqueous fraction at a dose of 240 mg/kg exhibited the effects similar to cimetidine. Then, the aqueous fraction was further separated by MPLC and yielded four sub fractions. Among those sub fractions, agent II at a dose of 40 mg/kg possessed the strongest effect in the HCl-ethanol induced gastritis. The water fraction yielded-Uridine, Adenosine, Guanosine, which were characterized by Mass, 1H-NMR, 13C-NMR. Conclusions : This study suggest that a P. oleracea and its compounds showed potent efficacy on the development of HCl-ethanol induced gastritis. Thus, P. olaracea can be a potential natural resource for the management of gastritis although the mechanism of action involved in the treatment remains to be explored.

Objective: The purpose of this study was to investigate the effect of combined therapy with Banhasasim-tang and conventional treatment for atrophic Gastritis. Methods: The study collected data of clinical studies of combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. Electronic databases were used, including PubMed, Cochrane, CNKI, Wanfang, CINII, J-stage, NDSL, and OASIS. The main search terms included such as "Atrophic Gastritis", "Banhasasim-tang", "BanXia Xiexin Tang". This study only included randomized controlled trials (RCTs) that adopted combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. Results: A total of 18 RCTs were selected. They all adopted combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. In all the studies, the intervention group significantly improved the score of effective rate, and in the 8 studies, Hp negative conversion rate was significantly improved when Banhasasim-tang was taken. Conclusion: Through the analysis of 18 RCTs, we found Banhasasim-tang combined with conventional therapy were more effective in the positive performance of atrophic gastritis than conventional therapy single contribution. However, due to the low quality of the selected studies and the lack of endoscopy, biopsy, follow-up observation, so there is a slight insufficient to prove its conclusion. Therefore, we hope that more systematic and diverse clinical studies will be conducted.

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.

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.

In this study, we investigated the protective action of glucuronopyranoside flavonoids (QGC, AGC, LGC) on gastritis in rats. QGC, AGC and omeprazole decreased the gastric volume significantly, and each $ID_{50}$ was 0.75, 0.54 and 8.5 mg/kg, respectively, thus the order of potency was AGC, QGC and omeprazole. They also decreased acid output, and each $ID_{50}$ was 7.81, 0.58 and 6.71 mg/kg, respectively, thus the order of potency was AGC, omeprazole and QGC. They inhibited gastritis induced by indomethacin, and it recovered significantly by increasing the GSH levels in gastritis. The gastric MPO activity in the gastritis group increased more than in the normal group. QGC, LGC, or AGC administration reduced moderately the MPO activity in a dose-dependent manner. This study demonstrated that AGC, QGC, or LGC showed potent efficacy on the gastritis, by preventing oxidative stress. These results suggest that QGC, AGC, or LGC have gastroprotective effect in rats.
