Influence of IL-1 gene cluster polymorphisms on the development of H. pylori associated gastric ulcer.

Background And Aims: Chronic H. pylori infection is the main cause of ulcer disease which depicts a major burden of our healthy care systems. The individual host immune response plays a pivotal role in the outcome of the infection but genetic susceptibility to develop gastric ulcer is unknown.

The results of "exercise therapy in coronary prone individuals and coronary patients".

The authors followed for at least two years 483 patients (430 coronary prone patients and 53 with proved coronary heart disease), to determine whether physical training could decrease coronary risk factors and improve exercise tolerance in the trained group as compared with the conventionally treated group (way of life, diet, drugs). There was no significant difference among the two groups for blood lipid profile, blood pressure (at rest and during exercise), functional capacity and mortality. In the authors' opinion this could be explained by the inadequate training program (45 minutes twice a week) and by a possible overlapping of the groups.
