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.

Infectious mononucleosis is Epstein-Barr virus (EBV) inducing a self-limiting clinical syndrome characterized by fever, sore throat, hepatosplenomegaly, and generalized lymphadenopathy. Gastrointestinal symptoms of EBV infection are nonspecific and occur rarely. EBV inducing acute gastrointestinal pathology is poorly recognized without suspicion. Careful consideration is needed to diagnose gastric involvement of EBV infection including gastric lymphoma, gastric cancer, and gastritis. A few recent cases of gastritis associated with EBV infection have been reported in adolescents and adults. However, there is no report of EBV-associated gastritis in early childhood. We experienced a rare case of 4-year-old girl with EBV gastritis confirmed by in situ hybridization.

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.

Objective : Yukgunja-tang is one of the herbal prescriptions widely used for functional indigestion. In this study, we evaluated the pharmacological effect through the Yukgunja-tang formulation development. Methods : The RAW 264.7 cells were pretreated with Yukgunja-tang tablet (YGJT-T : 50, 100 and 200 ㎍/㎖) and then stimulated with lipopolysaccharide (LPS : 500 ng/㎖). Cell viability, inflammatory mediators such as nitric oxide (NO) and prostaglandin E2 (PGE2) and inflammatory cytokines (IL-1β, IL-6, and TNF-α) were measured. Also, ICR mice induced acute gastritis by oral administration of 150 mM HCl in 60% ethanol. The YGJT-T (30 mg/kg) was pretreated for 3 days, and 150 mM HCl in 60% ethanol was orally administered 1 hour after the last drug treatment. Mice were sacrificed 1 hour after oral administration of 150 mM HCl in 60% ethanol. The gastric mucosa was observed, and inflammatory cytokines in the gastric tissue were measured. Results : The marker components of YGJT-T were determined by simultaneous analysis using HPLC. In RAW 264.7 cells, pretreatment of YGJT-T was non-toxic and inhibited the production of inflammatory mediators such as NO and PGE2 and suppressed inflammatory cytokines. In addition, pretreatment of YGJT-T improved bleeding and edema due to gastric lesions caused by acute gastritis and suppressed inflammatory cytokines. Conclusion : In summary, our results confirmed that treatment with YGJT-T has anti-inflammatory and anti-gastritis effects in vitro and in vivo. Therefore, in this study, YGJT-T could support a potential strategy for the prevention and treatment of gastritis.

Objectives : Pyeongwi-san is widely used in Korean medicine for acute indigestion or gastrodynia. As a therapeutic agent for digestive diseases of modern people, in order to confirm the mechanism of Pyeongwi-san on digestive tract disease and the difference of therapeutic efficacy between its formulation, a comparative efficacy test was conducted on digestive tract disease animal model. Methods : For LPS enteritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san, and then intraperitoneally administered LPS one hour later to induce enteritis. After 5 hours, blood was collected and TNFα, IL-1β, IL-6 and PGE2 were confirmed by ELISA. For acute gastritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san according to the prescribed concentration, and then intraorally administered 60% ethanol and 150 mM HCl one hour later to induce acute gastritis. After 5 hours, blood was collected and TNFα,IL-6 were confirmed by ELISA. Results : In the LPS-administered enteritis animal model, Pyeongwi-san decreased TNFα, IL-1β, PGE2 and especially IL-6. Pyeongwi-san also decreased IL-6 in acute gastritis animal model. In addition, there was no significant difference in efficacy between the two formulations when compared with inflammatory markers. Conclusions : The efficacy of Pyeongwi-san was confirmed in the inflammatory markers related to digestive inflammatory diseases, and the efficay between two formulations of Pyeongwi-san was relatively similar. Further studies are needed to investigate the new applicability of Pyeongwi-san on different inflammatory diseases that have similar inflammation markers identified in this experiment.

Objectives : Wiryeong-tang (WRT) is a traditional herbal medicine used to treat kidney-related diseases. However, the anti-inflammatory and anti-gastritis effect of Wiryeong-tang was not well known. Therefore, we experimented to confirmed the anti-inflammatory and anti-gastritis effects of Wiryeong-tang. Methods : The RAW 264.7 cells were pre treated with Wiryeong-tang mix soft extract (WRT-mse; 50, 100 and 200 ㎍/mL) for 1 hrs, and then incubated with lipopolysaccharide (LPS; 500 ng/mL). Cell viability was measured by the MTT method, and nitric oxide (NO) was measured with griess reagent. In addition, pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). For anti-gastritis effect in vivo, acute gastritis was induced using 150 mM HCl/60% ethanol used ICR mice. WRT-mse (133 mg/kg) was pre treated for 3 days and then treated with 150 mM HCl/60% ethanol 1 hrs later. Then gastritis was observed and inflammatory cytokines in the gastric tissue was measured. Results : The 8 marker components of the WRT-mse were determined by simultaneous analysis using HPLC. WRT-mse was not toxic and inhibited pro-inflammatory cytokines such as IL-1β, IL-6 and TNF-α at NO production, protein and mRNA levels. Also, it was confirmed that WRT-mse improved bleeding and edema in gastritis, and suppresses inflammatory cytokines. Conclusion : In summary, our results suggest that the treatment of the WRT-mse reduced and improved the 150 mM HCl/60% ethanol induced acute gastritis and the inflammation caused by LPS stimulation in RAW 264.7 cells. Therefore, this study may provide useful drug or clinical evidence for WRT-mse to prevent inflammation.

Anti-ulcer effects of depolymerized alginate (HAG-10, average molecular weight 10,000; HAG-50, average molecular weight 50,000; HAG-100, average molecular weight 100,000) obtained by hydrolysis of alginate by heating at $121^{\circ}C$, against $HCl{\cdot}ethanol$ and water-immersion stress in rats were investigated. The acute gastritis, induced by $HCl{\cdot}ethanol$, and the gastric ulcer, induced by water-immersion stress, were inhibited dose-dependently by administration of HAG-50, HAG-100 and alginate. Histopathological lesions of the gastritis and gastric ulcer in rats treated with HAG-50, HAG-100 and alginate were significantly lower than those in rats fed with HAG-10. The inhibition rates (${\%}$) on acute gastritis induced by $HCl{\cdot}ethanol$ and gastritis ulcer induced by water-immersion stress in rats, were $13.00{\%}\;and\;15.74{\%}$of HAG-10, $41.15{\%}\;and\;35.72{\%}$ of HAG-50, $41.58{\%}\;and\;35.37{\%}$ of HAG-100, and $45.17{\%}\;and\;41.11{\%}$ of alginate, respectively. These results suggested that HAG-50, HAG-100 and slginate had a protective effect against the gastritis and gastric ulcer. The effect was not as visible when using HAG-10 in rats. From the present results, it was suggested that HAG-50 was an effective anti-ulcer agent against $HCl{\cdot}ethanol$and water-immersion stress in rats.

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.
