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 : 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 : Gastric lesions affect many people around the world and their development are results of the imbalance between destructive and protective factors in the gastric mucosa. Lycium chinense has been widely used as a traditional Korean medicine, it was recently reported that they have potent anti-inflammatory effects in chronic hepatitis models. Therefore, this study aimed to investigate the anti-inflammatory activity of Lycium chinense extract (LCE) on HCl-Ethanol induced gastric lesion mice.Methods : The ICR mice were divided randomly into five groups of six animals each. Group A was normal mice, and group B was treated orally with 0.5 ml 150 mM HCl-60% Ethanol. Mice in group C and D were pre-treatment of LCE (100 mg/kg and 200 mg/kg bodyweight, p.o before HCl/ethanol treatment) and group E was orally administered sucralfate (10 mg/kg).Results : 150mM HCl/60% ethanol-induced gastric mucosal injury mice were ameliorated mucosal damage upon histological evaluation by treatment of LCE. Pre-treatment of LCE attenuated reactive oxidative species (ROS) and produces peroxynitrite (ONOO^-) in stomach tissues. As results of stomach protein analyses, LCE effectively reduce inflammatory-related factors such as cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin-6 (IL-6) in gastric lesion mice. In addition, nuclear factor kappa B (NF-κB) and inhibitor of phosphorylation of nuclear factor kappa B (p-IκB) were down-regulated in LCE-administrated gastric lesion mice.Conclusions : Our discovery supports that the therapeutic activity of LCE ameliorate the development of gastric lesion via suppressing the oxidative stress and gastric partial inflammation induced by 150 mM HCl/60% ethanol.

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.

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.
