Hemodialysis patients were treated with Wen-Pi-Tang (a type of traditi
onal Chinese (Kampo)-prescription) for 8 weeks, and the changes in act
ive oxygen production by neutrophils, superoxide dismutase (SOD) activ
ity, methylguanidine (MG)/creatinine (Cr) ratio, blood chemistry and s
ubjective symptoms were examined. A decrease in active oxygen producti
on by neutrophils was observed in patients with and without phorbol my
ristate acetate stimulation. SOD activity and MG/Cr ratio were also re
duced by the treatment. In addition, coldness of the limbs, constipati
on and easy fatigability were improved by Wen-Pi-Tang administration.
