Effects of Salvionolic Acids Dialyzate on Biocompatibility of Hemodialysis Polysulfone Membrane / 中国药房

ABSTRACT

OBJECTIVE:To study the effects of Salvionolic acids dialyzate on anaphylatoxin,C-reactive protein(CRP),interleukin-6(IL-6)and tumor necrosis factor-?(TNF-?)in peripheral blood of patients with maintenance hemodialysis(MHD)and to discuss whether the Salvionolic acids dialyzate could improve the blood-membrane biocompatibility.METHODS:Thirty-six patients undergoing MHD for at least half a year were randomly divided into 3 groupscontrol group(conventional hemodialysis,n=12),low-dose group(dialysate with salvionolic acids 40 mg?L-1,n=12)and high-dose group(dialysate with Salvionolic acids 80 mg?L-1,n=12).Dialyzer of the polysulfone membranes was firstly used in all patients.Patients' blood sampling was scheduled before dialysis,30 minutes after dialysis and at the end of dialysis(5 minutes before withdrawal of dialyzer)for measurement of serum levels of complement(C3a,C5a),CRP,IL-6 and TNF-? using enzyme linked immunosorbent assay(ELISA).RESULTS:As compared with before dialysis,the levels of C3a and C5a in both control group and low-dose group were evidently increased at 30 minutes,while the difference in high-dose group was nonsignificant.No significant differences of IL-6 and TNF-? were found between pre-dialysis and post-dialysis in three groups.As compared with before dialysis,the concentration of CRP in control and low-dose groups obviously increased but decreased obviously in high-dose group after dialysis.CONCLUSION:The production of C3a,C5a and CRP in the process of hemodialysis could be inhibited by a certain dose of Salvionolic acids dialyzate,which can improve the biocompatibility of the dialysis-membrane to some degree,but can't improve the levels of IL-6 and TNF-? after single-time dialysis.
