the addition of each subfraction to lipoprotein deficient medium allowed us to distinguish two categories of lipoproteins : firstly , those with density d greater than 1.030 , ldl , hdl2 and hdl3 which showed a marked inhibitory activity on cfuc and cfue proliferation and , secondly , those with density d less than 1.030 , vldl and idl which did not show any inhibitory activity .
