13. Identification of medicinal plants of Urmia for treatment of gastrointestinal disorders
The gastrointestinal tract is one of the most important organs of the human body and is vulnerable to different diseases. Available drugs often have low efficacy or are associated with many adverse effects. Therefore, alternative drugs are necessary to treat gastrointestinal complications. This study intended to identify medicinal plants in Urmia, Iran, that

14. Evaluation of sodium diclofenac release using natural rubber latex as carrier
Sodium Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) taken to reduce inflammation and, as an analgesic, reduce pain. Although this drug is widely used in the general population, properties such as the short half-time and some side effects restrict its clinical use. The most common side effects are: gastric irritation, gastritis, peptic ulcer a

15. Investigation of the association between clinical outcome and the cag pathogenicity-island and other virulence genes of Helicobacter pylori isolates from patients with dyspepsia in Eastern Turkey
The aims of our work were to determine the presence of the cag pathogenicity-island (cag PAI) and other virulence genes of Helicobacter pylori recovered from patients with gastritis and peptic ulcer, and to investigate the correlation of these virulence genes with clinical outcome. The presence of the cagA, the promoter regions of cagA, cagE, cagT, and the l

16. InvestigaÃÃo dos mecanismos de aÃÃo da atividade gastroprotetora de 1,4-cineol em modelos de Ãlcera gÃstrica em camundongos. / Investigation of mechanisms of action of gastroprotective activity of 1,4-cineole in gastric ulcer models in mice.
1,4-Cineol à um monoterpeno Ãter amplamente distribuido, o qual à um dos constituintes responsÃveis pelo odor do limÃo. O objetivo deste trabalho foi avaliar o efeito gastroprotetor de 1,4-Cineol (CIN 100 e 200 mg/Kg) nos modelos de lesÃo induzidas por etanol ou piroxicam em camundongos e, posteriormente, investigar os possÃveis mecanismos de aÃÃo f

17. Prevalence of genotypes in Helicobacter pylori isolates from patients in eastern Turkey and the association of these genotypes with clinical outcome
There is not much information available regarding the prevalence of the genotypes of Helicobacter pylori isolates in Turkey, particularly in eastern Turkey. The aims of this study were to detect the prevalence of different genotypes of H. pylori in Turkish patients with gastrointestinal complaints and to determine the relationship of these genotypes with cli

18. Evaluation of diagnostic methods for the detection of Helicobacter pylori in gastric biopsy specimens of dyspeptic patients
Helicobacter pylori infects nearly 50% of the world's population. This microorganism is accepted as the most important agent of gastritis and as a risk factor for peptic ulcer disease and gastric adenocarcinoma. Currently many diagnostic methods exist for detecting H. pylori, however they all have limitations, thus it is recommend a combination of at least t

19. Helicobacter pylori vacA and cagA genotypes in patients from northeastern Brazil with upper gastrointestinal diseases
Helicobacter pylori causes chronic gastric inflammation and significantly increases the risk of duodenal and gastric ulcer disease and distal gastric carcinoma. In this study, we evaluated the Helicobacter pylori vacA and cagA genotypes in patients from a Brazilian region where there is a high prevalence of gastric cancer. Polymerase chain reaction (PCR) was

20. Characterization of virulence genes cagA and vacA in Helicobacter Pylori and their prevalence in gastrointestinal disorders
Prevalence of H. pylori infection was determined using cultures of gastric biopsy samples of patients attended at the academic hospital of the Federal University of Paraná, Curitiba, Paraná, Brazil. Molecular methods were used to characterize the cagA and vacA genes from bacterial isolates associated with different diseases presented by patients. Out of a

21. Epstein-Barr virus DNA load and its association with Helicobacter pylori infection in gastroduodenal diseases
Helicobacter pylori and Epstein-Barr virus (EBV) infections are common worldwide. Although H. pylori infection is a major factor in gastroduodenal diseases, its role in association with EBV infection is unknown. Objective: To study the association of H. pylori infection and EBV DNA load in patients with gastroduodenal diseases. Methods: Biopsy samples were c

22. Gastroprotective effects of essential oil from Protium heptaphyllum on experimental gastric ulcer models in rats
Peptic ulcers are a common disorder of the entire gastrointestinal tract, its etiology has not been completely elucidated. The basic physiopathological of peptic ulcers result from an imbalance between some endogenous aggressive factor and cytoprotective factors. The treatment of this disease is usually done with antacids or proton pump, but are currently be

23. Helicobacter pylori transiently in the mouth may participate in the transmission of infection
Helicobacter pylori infection is associated with peptic ulcer and gastric carcinoma. The oral cavity may be a reservoir for H. pylori; however, the results of studies on this subject are controversial. We employed single-step and nested polymerase chain reactions (PCR) to detect the presence of the vacA, ureA and 16S rDNA genes of H. pylori in the stomach, s

24. Helicobacter pylori detection in gastric biopsies, saliva and dental plaque of Brazilian dyspeptic patients
Helicobacter pylori is an important human pathogen that causes chronic gastritis and is associated with the development of peptic ulcer disease and gastric malignancies. The oral cavity has been implicated as a potential H. pylori reservoir and may therefore be involved in the reinfection of the stomach, which can sometimes occur following treatment of an H.
