and the mean observed peak plasma metoprolol concentration by about 33%. Furthermore, the elimination half life of metoprolol was prolonged from 3-9 hours during monotreatment to 6-0 hours when ranitidine was given in combination (p<0005). There was no evidence that any of the volunteers were poor metabolisers of metoprolol. Beta-blockade was assessed on the sixth treatment day by examining the...

BACKGROUND/AIM IgA deficiency is the most common human primary immunodeficiency. The prevalence of allergic disorders and autoimmunity is thought to be increased in selective IgA deficiency (sIgAD). However, it is currently unclear if these disorders coincide within these families. We aimed to evaluate the frequency of allergic and autoimmune disorders in children with sIgAD and their first-deg...

Dietary methionine (met) is reported to enhance antibody production and boost cell-mediated immunity in chickens. Methionine deficiency has been shown to affect the development of the lymphoid organs and the generation of antibodies in chickens. This study is designed to investigate the effects of met deficiency on IgA+ B cells and immunoglobulins (sIgA, IgA, IgG and IgM) for a 6 wee...
