Introduction: Extract of Ginkgo biloba (EGb), a dietary supplement used for a number of conditions including dementia, has been suggested to increase cerebral bloodflow (CBF). The purpose of this study was to determine if changes in CBF could be detected by dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI)in elderly human subjects taking EGb.
Methods: DSC-MRI was performed in nine healthy men(mean age 61±10 years) before and after 4 weeks of 60 mg EGb taken twice daily.

Celiac disease has been associated with other autoimmune disorders such as autoimmune hepatitis, moreover it is known that T cell mediated immune response to dietary gluten and released cytokines are important for the entheropathy seen in celiac disease. We investigated celiac autoantibodies in patients with autoimmune hepatitis (AIH), and chronic hepatitis B (CHB).Sera from 84 patients with Autoimmune Hepatitis (AIH) type 1 and 88 patients with Chronic Hepatitis B (CHB) were tested for Immunoglobulin A and G antibodies to Gliadin, Immunoglobulin A antibodies to tissue transglutaminase using enzyme immunoassay, and Immunoglobulin A anti-endomysial antibodies by both indirect immunofluorescence, and enzyme immunoassay.

This method was applied to 13 patients and normal controls. The reliability of the automated segmentation revealed close agreement with the manual segmentation.

Background And Aim: Epidemiological studies have indicated an increase in the prevalence of gastroesophageal reflux disease in Western countries; however, there is a lack of information about its prevalence in Iran. The aim of this study was to measure gastroesophageal reflux disease prevalence in a representative sample of the Tehran population in 1999.
Methods: In a cross-sectional study, 700 people, with a male : female ratio of 1:1, were selected by stratified randomization based on the probability of 20% prevalence of gastroesophageal reflux disease and 3% error.
