The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.

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.

The present study investigated the protective effect of naturally purified 4-(3,4-dihydroxyphenyl)-3-buten-2-one (DHP) from Phellinus linteus against naproxen-induced gastric antral ulcers in rats. To verify the protective effect of DHP on naproxen-induced gastric antral ulcers, various doses (1, 5, and 10 μg/kg) of DHP were pretreated for 3 days, and then gastric damage was caused by 80 mg/kg naproxen applied for 3 days. DHP prevented naproxen-induced gastric antral ulcers in a dose-dependent manner. In particular, 10 μg/kg DHP showed the best protective effect against naproxen-induced gastric antral ulcers. Moreover, DHP significantly attenuated the naproxen-induced lipid peroxide level in gastric mucosa and increased the activities of radical scavenging enzymes, such as superoxide dismutase, catalase, and glutathione peroxidase, in a dose-dependent manner. A histological examination clearly demonstrated that the gastric antral ulcer induced by naproxen nearly disappeared after the pretreatment of DHP. These results suggest that DHP can inhibit naproxen-induced gastric antral ulcers through prevention of lipid peroxidation and activation of radical scavenging enzymes.

Objectives : The objective of this study was to evaluate the gastric protective effect of Curcuma Longae Rhizoma (CLR) in 150 mM HCl/60% ethanol induced gastric ulcer (GU) in mice. Methods : Forty ICR mice were divided into five groups (n=8/Group): Nor group; Normal, Veh group; GU control, SC group; GU + sucralfate 10 mg/kg, CL; GU + CLR 30% ethanol extract 100 mg/kg, CH group; GU + CLR 30% ethanol extract 200 mg/kg. Then, mice were orally administered with 150 mM HCl/60% ethanol and caused GU. After 1 hr, mice were sacrificed, and blood and stomach tissue were collected. Results : CLR showed significance scavenging effects in 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities (DPPH IC₅₀; 78.18 ± 0.60 ㎍/㎖, ABTS IC₅₀; 55.91 ± 1.86 ㎍/㎖). CLR significance reduce inflammatory-related factors such as cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin-6 (IL-6) via nuclear factor kappa B (NF-κB) inactivation. In addition, the activation of nuclear factor erythroid2-related factor 2 (Nrf2) significantly led to up-regulation of anti-oxidant enzymes including factors heme oxygenase-1 (HO-1), super oxide dismutase (SOD), and glutathione peroxidase-1/2 (GPx-1/2). Conclusions : Our discovery provides that CLR possesses anti-oxidant and anti-inflammatory effects. Hence, CLR may ameliorate the development of gastric ulcer though the inhibition of NF-κB inflammatory pathway and the elevation of Nrf2 anti-oxidant pathway.

The aim of the study was to observe the influence and related mechanism of rebamipide on the intestinal contraction. Intestinal contraction includes the activation of thick or thin filament regulation. However, there are few reports addressing the question whether this regulation is involved in rebamipide-induced regulation. We hypothesized that rebamipide plays a role in intestinal contraction evoked by carbachol in rat intestine. Interestingly, rebamipide alone didn't inhibit and rather slightly increased the contraction in the denuded muscle. Therefore, rebamipide alone and together with indomethacin increases the ileal contraction suggesting that additional pathways might be involved in the regulation of ileal contractility. In conclusion, rebamipide has some effect on the regulation of contractility and anti-ulcer by NSAIDs.
