Objectives: Gastric ulcer is a chronis disease with a lot of dangerous complications and H. pylori is a major cause of gastric ulcer. Eradicating H. pylori helps reducing ulcer relapse and preventing cancer. The aim of study: to evaluate the rate of H. pylori infection in gastric ulcer and efficacy of quadruple therapy RACM for 5 days in patients with gastric ulcer with H. pylori positive. Materials and methods: Total 98 patients with gastric ulcer have been performed the endoscopy and CLO-Test, treated with quadruple therapy RACM for 5 days and evaluate efficacy 4 weeks after ending treatment. Results: The rate of H. pylori in gastric ulcer is 82.65%. The rate of H. pylori eradication is 88.71%. The effect of reducing pain of therapy is 90.32%; and the rate of reducing pain: 96.37% in successfully H. pylori-eradicated group and in the other group 42.85% (p < 0.05). The effect of healing ulcer of therapy is 77.41%; and the rate of healing gastric ulcer: 83.63% in successfully H. pylori-eradicated group and in the other group 28.57% (p < 0.05). The adverse effects of therapy included tiredness: 11.29%, lose appetite: 8.06% and diarrhea: 6.45%. Conclutions: Quadruple therapy RACM for 5 days showed an effective, safe and simple regime for eradicating H. pylori and should be considered to apply as the first lines treatment for H. pylori.

Background: Ingested foreign things in peptogaster are acute cases that are frequently seen in clinical practices. Flexible endoscopic removal of the ingested foreign things is now the first choice. Aims: Investigating characsteristics of ingested foreign things, and evaluating the efficacy and safety of endoscopic removal techniques. Subjects and Methods: 47 patients participated in the study. Diagnosis of ingested foreign things have made by history, clinical manifestations, X – ray and endoscopy????. The used instruments are conventional flexible endoscopy and assessories???. Results and Discussion: The ingested foreign things are duck bones 31,9%, fish bones 29.8%, chicken bones 12.8%, dental prostheses 12.8%, pig bones 10.6% and bamboo sticks 2.1%. Endoscopic removal have been successfully performed making up 93.6%.There were some minor complications such as bleeding erosions (4.4%), no case with serious complications. Conclusion: Flexible endoscopic removal is an effective and relatively safe procedure for patients with digested foreign things.

Background: Clarithromycin resistance of H-pylori is the main cause leading to treatment failure. Aim: The purpose of this study was to determine the rate of clarithromycin resistance mutation on gene 23S ribosomal popular robonucleotide acid (rRNA) of H-pylori in patients with chronic gastritis in Quang Ngai General Hospital PCR-RFLP. Method: This is a cross-sectional study in 64 patients infected with H-pylori was determined by 3 methods and chronic gastritis proven by histology. Sample collection conducted in Quang Ngai general hospital and molecular biology tests were conducted in the medical genetics department Hue of Medical and Pharmaceutical University. Urease test, histopathological examination and perform HE staining PCR 23S rRNA gene fragment of H-pylori to determine H-pylori infection. Analysis of genetic mutations in the 23S rRNA point is performed by PCR-RFLP technique. Results: Of the 64 biopsies qualify included in the study, 41 samples with clarithromycin resistance point mutations (64%), of which 40 (62.5%) had mutations A2143A, one sample with A2142A (2%). No samples had mutations A2142C and no more than one mutation.Conclusion: This is the first time we report mutations related to clarithromycin of H-pylori in Quang Ngai province. Mutations rate is high (64%), among the common mutations, the most common mutantation is A2143G. Key words: Helicobacter pylori, clarithromycin resistance, PCR-RFLP, point mutations
