Analysis of Hemorrheology and trace elements contents in patients with oral recurrent aphthae ulcer

Objective:To investigate the effects of Hemorrheological factors and related trace elements on oral recurrent aphthae ulcer (RAU). Methods:Selected 83 patients with RAU from volunteer blood donors. Detected the Hemorrheological indicators and the contents of Mg , Fe , Zn , Se and Cu. Comparative Analysised them with healthy volunteers. Results : The patients with RAU’s levels of whole blood viscosity , whole blood reduced viscosity , plasma viscosity and hematocrit are higher than the control one ( P0.05 ) .Erythrocyte electrophoresis time is prolonged , and erythrocyte sedimentation rate is dropped ( P0.05 ) .The contents of Zn and Se are lower than the control one ( P0.05 ) . However , there is no statistical significance about the contents of Mg , Fe and Cu between the two groups ( P0.05 ) . Conclusion : Patients with RAU may be lack of Zn and Se.Furthermore , there are changes of Hemorrheological circumstances.This research provide references for the clinical treatments of RAU by means of improving blood circulation or supplement Zn and Se rationally.
