Helicobacter pylori and gastroesophageal reflux disease: a review of this intriguing relationship.

A possible association between gastroesophageal reflux disease (GERD) and Helicobacter pylori (H. pylori) infection has been the subject of study and debate in recent years. This review discusses the pathophysiological and immunological mechanisms implicated in this relationship.

Comparative study of respiratory burst induced by phorbol ester and zymosan in human granulocytes.

Objectives: We have comparatively evaluated respiratory burst and some steps of its signaling in human granulocytes towards different stimuli.

Materials And Methods: An alternative method to remove erythrocytes by dextran differential sedimentation was employed. Respiratory burst (RB) was assessed in a flow cytometer by the oxidation of a fluorescent probe (dichlorodihydrofluorescein).
