This study was designed to evaluate the gastroprotective activity of cirsilineol in hydrochloric acid (HCl)/ethanol-induced gastric ulcer model. Cirsilineol was administered at the doses of 20 and 40 mg/kg in HCl/ethanol-induced rats. The gastroprotective ability was verified by determining the ulcer score, total acidity, hemoglobin, inflammatory cytokines, lipid peroxides, and enzymatic antioxidants superoxide dismutase (SOD) and catalase (CAT) in gastric tissue and serum biochemical analysis. The results showed a favorable increase in the hemoglobin level, antioxidant enzymes (SOD and CAT), restored electrochemical balance (carbon dioxide & anion gap) while a noticeable decrease in ulcer index, total acidity, lipid peroxides, inflammatory cytokines (interleukin-1 beta [IL-1β], IL-6, and tumor necrosis factor alpha) in rats treated with the cirsilineol. The serum biochemical analysis on liver markers (alkaline phosphatases, alanine aminotransferase, and aspartate aminotransferase), kidney markers (urea, creatinine, albumin, globulin, total protein), and lipid profile (triglyceride, high-density lipoprotein, total cholesterol) were attenuated by cirsilineol treatment in rats. Histopathology showed enhanced gastric protection and preserved the integrity of gastric mucosa upon cirsilineol administration. These results ultimately suggest that cirsilineol has gastroprotective effects that prevent the development of gastric ulcer.

Background: Gastric ulcer (GU) is a common gastrointestinal disease that can be induced by many factors. Finding an effective treatment method that contains fewer side effects is important. 20 (S)-ginsenoside Rg3 is a kind of protopanaxadiol and has shown superior antiinflammatory and antioxidant effects in many studies, especially cancer studies. In this study, we examined the treatment efficacy of 20 (S)-ginsenoside Rg3 on GU. Methods: Three kinds of GU models, including an alcohol GU model, a pylorus-ligated GU model, and an acetic acid GU model, were used. Mouse endothelin-1 (ET-1) and nitric oxide (NO) levels in blood and epidermal growth factor (EGF), superoxide dismutase, and NO levels in gastric mucosa were evaluated. Hematoxylin and eosin staining of gastric mucosa and immunohistochemical staining of ET-1, inducible nitric oxide synthase (NOS2), and epidermal growth factor receptors were studied. Ulcer index (UI) scores and UI ratios were also analyzed to demonstrate the GU conditions in different groups. Furthermore, Glide XP from $Schr{\ddot{o}}dinger$ was used for molecular docking to clarify the interactions between 20 (S)-ginsenoside Rg3 and EGF and NOS2. Results: 20 (S)-ginsenoside Rg3 significantly decreased the UI scores and UI ratios in all the three GU models, and it demonstrated antiulcer effects by decreasing the ET-1 and NOS2 levels and increasing the NO, superoxide dismutase, EGF, and epidermal growth factor receptor levels. In addition, high-dose 20 (S)-ginsenoside Rg3 showed satisfactory gastric mucosa protection effects. Conclusion: 20 (S)-ginsenoside Rg3 can inhibit the formation of GU and may be a potential therapeutic agent for GU.

Gastric ulcer is a clinical symptom characterized by inflammation of the gastric mucosa. Stress and alcohol consumption have been identified as the major cause of gastric ulcer. However, the effects of silkworms on ethanol-induced gastric ulcer have not been studied yet. The mature silkworms that are difficult to eat have become easier to ingest due to recent technological development to make steaming and freeze-drying mature silkworm larval powder (SMSP). In this study, we investigated whether three silkworm varieties, Baekokjam, Golden-silk and Yeonnokjam could alleviate ethanol-induced gastric mucosal damage in vivo. Sprague-Dawley rats pretreated with 3 SMSPs (0.1 or 1 g/kg BW) or normal diet (AIN-76A) were exposed to absolute ethanol (3 g/kg BW, 3 h) by oral gavage. Morphological examination included ulcer index as a measurement of hemorrhages and hematoxylin and eosin staining was performed to analyze the severity of gastric ulcer. Results of macroscopic examination suggested that all 3 SMSPs pretreatment significantly protected gastric mucosa against ethanol-induced damage. Microscopic observations demonstrated significant mucosal erosion and inflammation in ethanol-treated rats, which was abrogated in rats pretreated with 3 SMSPs. In addition, pretreatment with all 3 SMSPs showed significant decreases the expression of pro-inflammatory mediators, IL-6 and cyclooxygenase-2. Among SMSP from 3 varieties of silkworm, preadministration of 1 g/kg Baekokjam SMSP showed the most effective protective effect against ethanol-induced gastric ulcer. These results suggest that Baekokjam SMSP can be a potential gastroprotective agent against ethanol-induced gastric ulcer.

This study aimed to verify the nutritional and curative effects of protein hydroysate and optimal ratio between protein and protein hydroysate as nitrogen source in rats with cysteamine-induced duodenal ulcer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intrapertionealy injected twice cysteamine(13mg/100g BW) at intervals of 3hours per day. This procedure was repeated 3 times at intervals of 3 days. Animals fed on 10% casein diet for injection periods. After last injection, 5 kinds of kiets (the ratio of casein and casein hydrolysate was 100 : 0(C100), 75 : 25(CH 25), 50 : 50(CH 50), 25 : 75(CH 75), 0 : 100(CH 100)) were given. The rate were sacrificed after feeding diet, 1, 3, 5 days. Ulcer index, hexosamine content of stomach and duodeum, gastric motility, trypsin activity, blood glutathione, plasma total protein, albumin, amino-N, urinalry urea nitrogen, creatinine, hydroxyproline and retention rate of nitrogen were analyzed for nutritional effects of diet treatments. There were no differences among diet groups in the view of the growth and diet treatments. There difference of ulcer curation by diet was appeared after 3 days. The ulcer indexes of C100 and CH 25 of 3, 5 days were significantly higher than those of CH 50, CH 75 and CH 100. This result was the same as hexosamine content of stomach, plasma protein, albumin concentration and nitrogen retention rate. The more casein hydrolysate diet had, the lower trypsin activity was. The more casein gydroysate diet had, the higher excretion of hydroxyproline was. These results show that protein hydrolysate can be applied in diet therapy for the patients with gastronitestinal ulcer. It suggests that it has curative effect of diet when nitogen sources include at least over than 50% of protein hydrolysate.

This project's aim was to determine the reserpine-induced gastric ulcer preventive effect of polysaccharide of Larimichthys crocea swim bladder (PLCSB) in ICR mice. The anti-gastric ulcer effects of polysaccharide of Larimichthys crocea swim bladder was evaluated in mice model using morphological test, serum levels assay, cytokine levels assay, tissue contents analysis, reverse transcription-polymerase chain reaction (RT-PCR) analysis and western bolt assay. High concentration (50 mg/kg dose) of PLCSB reduced IFN-${\gamma}$ as compared to low concentration (25 mg/kg dose) and control mice. SS and VIP serum levels of PLCSB treated mice were higher than those of control mice, and MOT and SP serum levels were lower than control mice. Gastric ulcer inhibitory index of PLCSB treatment groups mice were much lower than control mice, and the high concentration treated mice were similar to the ranitidine treated mice. The SOD and GSH-Px activities of PLCSB treated mice were higher than control mice, close to normal mice and ranitidine treated mice. PLCSB treated mice also showed the similar contents of NO and MDA to normal group. By RT-PCR and western blot assay, PLCSB significantly induced inflammation in tissues of mice by downregulating NF-${\kappa}B$, iNOS, and COX-2, and upregulating $I{\kappa}B-{\alpha}$. These results suggest that PLCSB showed a good gastric ulcer preventive effect as the gastric ulcer drug of ranitidine. Polysaccharide of Larimichthys crocea swim bladder may be used as a drug material from marine products.

Trichosanthes cucumerina Linn. (cucurbitaceae) is widely used in Indian folk medicine for variety of disease conditions. The aim of present study was to evaluate the antiulcer activity of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. (TCFE) using various experimental models of gastric and duodenal ulceration in rats. Oral administration of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. was evaluated in rats against ethanol, aspirin and pylorus ligated gastric ulcers as well as cysteamine-induced duodenal ulcers. In all the models studied, the antiulcer activity of TCFE compared with that of cimetidine (100 mg/kg, p.o.), an $H_2$ receptor antagonist. TCFE showed significant antiulcer activity in ethanol-induced and aspirin-induced gastric ulcer models. In 19 h pylorus ligated rats, significant reduction in ulcer index, total acidity and pepsin activity was observed with TCFE, when compared with the control group. Mucosal defensive factors such as pH, mucin activity and gastric wall mucous content was found to be increased with TCFE. TCFE was also, afforded remarkable protection in cysteamine-induced duodenal lesions. The antiulcer activity of TCFE was comparable with that of cimetidine. Thus, TCFE possess significant antiulcer activity against both gastric and duodenal ulcers in rats. The antiulcer activity may be attributed to its cytoprotective action and inhibition of acid secretary parameters.
