ABSTRACT
Sixty patients who had hemodialysis over half year were randomly divided into 3 groups with 20 cases in each group:group A received conventional hemodialysis,group B received hemodialysis with oral administration of compound danshen (salvia miltiorrhiza bunge) tablets and vitamin E,group C had the same treatment as group B but the dialyzer was pretreated with solution containing 5 g vitamin C ; 20 healthy adults served as normal controls. Serum levels of advanced oxidation protein products (AOPP) and superoxide dismutase (SOD) were measured in all groups.The levels of AOPP in groups A,B,C were higher and SOD levels were lower than those of normal controls ( all P ＜ 0.01 ).The levels of AOPP in groups B,C were lower and SOD were higher than those in group A at the same time points (P ＜0.01 ).The levels of AOPP in group C were lower and SOD were higher than those in group B at the same time points (P ＜0.0l ).The results suggest that pretreatment of the dialyzer with high dose vitamin C plus vitamin E and compound danshen tablets can alleviate oxidative stress in patients with maintaining hemodialysis.
