The Relationship

H2 receptor antagonist (H2RA) and proton pump inhibitor(PPI) are often used to treat gastric ulcers, in addition to the zinc-L-carcino-complex which is commonly adopted for such therapies. However, there have been no previous reports detailing the levels and distribution of zinc in human gastric mucosa. The aim of our current study is to clarify the relationship between Helicobacter pylori infection and trace elements such as zinc in gastric mucosa using particle induced X-ray emission (PIXE). Forty gastric ulcer patients were chosen as subjects of this study and divided into two groups. One is a new ulcer patients group(twenty nine cases). And the other, eleven of these patients had been prescribed zinc-L-carcino-complex (polapreZinc®), at a dose of 150mg/day for periods ranging from 16 to 20 weeks. The zinc levels in the gastric ulcer group were found to be significantly less than those of the control group and the concentrations of zinc in gastric mucosa were observed to increase following the administration of treatments containing this element.

The purpose of this study is to clarity how trace elements in gastric mucosa, reflex bile acid and inflammation of gastric mucosa relate to environment of Helicobacter Pylori. Subjects were 33 patients who had colonic endoscopic examination. 11 gastric ulcer and 14 duodenal ulcer patients were chosen as subjects of the study. The control group had 8 members who had no localized lesions. Trace elements were measured by PIXE analysis which use Pd as internal standard. Cu and Zn , especially Zn , were found in large amount in gastric body and antrum. Zn value for the antrum was higher than that for the gastric body. Especially, the values of Zn for antrum showed significant differences between grade I, II and grade III of inflammatory cell infiltration. In gastric ulcer group, the value of Cu indicated high at gastric body and low at antrum. On the other hand, the values of Zn were low at both gastric body and antrum. Particularly, development of atrophy in antrum requires less than one in gastric body; therefore, trace elements decreased in gastric ulcer group.

Giant gastric ulcer (GGU) is defined as an ulcer more than 3 cm in diameter. Now infrequent in clinical practice, in the pre-H2 receptor antagonist (H2RA) era, the incidence of GGU varied between 12 and 24% of all gastric ulcers. Proton pump inhibitors reportedly achieve better healing rates and symptom relief in comparison to H2RA. The GGU is associated with high incidence of serious complications such as hemorrhage. A perforated GGU though rare (<2%) offers serious challenges in management. We report one such case wherein the role of multidetector CT scan (MDCT) for diagnosis and treatment planning, surgical options for GGU perforations, and factors affecting outcome are discussed.

Chronic gastritis and gastric ulcers are prevalent throughout the world and are considered to be a global health problem. Modified Xiaochaihutang (MXCHT) prescription is broadly used in traditional medicine hospital for the treatment of gastritis. In order to assess the anti-Helicobacter pylori (H. pylori) effect of MXCHT, agar diffusion method in vitro and fluid dilution method for the minimal inhibitory concentration (MIC) were established. The anti-inflammatory effects were then evaluated using mouse ear edema model and rat paw edema model. The ethanol-induced gastric ulcer method was employed to verify the gastroprotective effect of active extracts in MXCHT. HPLC-TOF-MS/MS was used for analyzing the possible active constituents after oral administration of effective extracts in ethanol-induced gastric ulcer models. MXCHT and 4 different extracts of the bacterial inhibition diameter and MIC were dramatically decreased compared with control group, showing anti-Helicobacter pylori effects. High dose groups of MXCHT, water extract, EtOAc extract, and n-BuOH extract displayed significant anti-inflammatory effects in xylene-induced mouse ear edema model and carrageenan-induced rat paw edema model test. MXCHT and all active extracts exhibited gastroprotective activity and prevented gastric lesions induced by ethanol in rats. 4 prototype components and 4 metabolites were identified after oral administration of EtOAc extract. In addition, 6 prototype components and 6 metabolites were identified in n-BuOH extract. MXCHT, EtOAc extract, and n-BuOH extract demonstrate gastroprotective effects through anti-Helicobacter pylori and anti-inflammatory activities. Thus, this prescription may be a suitable natural source for the prevention and treatment of chronic gastritis and gastric ulcers.

Background. Two major causes of gastric ulcers areHelicobacter pylori(H. pylori) infection and nonsteroidal anti-inflammatory drug (NSAID) use.Aims. This study aimed to determine if there were different expressions of matrix metalloproteinases (MMPs) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) betweenH. pylori-infected and NSAID-related ulcers.Methods. The 126 gastric ulcer patients (H. pyloriinfectedn=46; NSAID relatedn=30; combined with two factorsn=50) provided ulcer and nonulcer tissues for assessment of MMP-3, -7, and -9 and TIMP-1 expression by immunohistochemical staining.Results. Gastric ulcer tissues had significantly higher MMP-3, -7, and -9 and TIMP-1 expressions than nonulcer tissues (P<0.05).H. pylori-infected gastric ulcers had even higher MMP-7, MMP-9, and TIMP-1 expressions in epithelial cells than NSAID-related gastric ulcers (P<0.05). In patients with the two combined factors, gastric ulcers expressed similar proportions of antral ulcers and MMP-7 and MMP-9 intensities to NSAID-related gastric ulcers, but lower MMP-9 and TIMP-1 thanH. pylori-infected gastric ulcers (P<0.05).Conclusions. H. pylori-infected gastric ulcers express higher MMP-7, MMP-9, and TIMP-1 than NSAID-related ulcers. In patients with the two combined factors, ulcer location and MMP-7 and MMP-9 intensities are similar to NSAID use.
