Abstract: This study investigated the influence of hemodialyzer membranes on apoptosis of peripheral blood mononuclear cell. PBMC were seperated from whole blood donated by healthy volunteers . They were incubated in vitro in the presence of either CU membrane or Gambrane membrane . Control cells were incubated in absence of HD membranes. The cells were collected at regular intervals. PBMC apoptosis were evaluated with flowing cetometric analysis. The results indicated that the apoptosis of PBMC in each group increased more obviously than that before the incubation 48 h ago. Apoptosis of CU group was(36.31±1.40)%, significantly higher than other two groups(P<0.05). CU membrane, a bioincompatible HD membrane, can induce the isolated PBMC to apoptosis more easily than others.

Key words: hemodialysis membrane, apoptosis, biocompatibility
