Objective To evaluate the performance of a novel extracorporeal hpoprotein filter,JX-DELP.Methods The adsorptionof the filter membrane to lipoproteins was examined by in-vitro static adaorption method.A pocket filter which simulates the product,JX-DELP,W88 designed and made.An extracorporeal circulation system was established using the pocket filter and clinical application was imitated.The influences of plasma volume,flow rate and filtering time on the removal of lipopmteins were tested in a flow condition.The biocompatibility of the falter Was evaluated by incubating the membrane with whole blood.Results The in vitro removal rates of the filter membrane to lipeproteim are:TC 16.7%,TG 9.7%,and LDL 13.5%,respeetaively.In the extracorporeal circulation systemthe removals of TC,TG,and LDL were 52.0%,50.1%,and 38.4%,respectively.However,the reductions of other components in plasma were negligible.The filter membroJle did not change the normal components in the whole blood,and the hemolysis rate was low as 0.19%.It suggests that the filter has good blood compatibility.Conclusion The llish level of lipoproteins in hyperlipeidemia patients could be efficiently removed by the novel extracorpereal hpoprotein filter,JX-DELP.It may be effective in treatment of hyperlipoidemia related diseases.
