The changes of plasma lipoproteins which occur during the development of nephrotic syndrome induced in the rat were investigated by the administration of the antineoplastic drug adriamycin. Rats received a single intravenous injection of the drug (7.5 mg/Kg) and were sacrificed 5, 10, 15, 20, 25,
Lymph chylomicrons and plasma VLDL, 14C-labelled in vivo, were isolated from normal and nephrotic rats and injected into normal or nephrotic recipients. In normal recipients, the half-life of chylomicrons of nephrotic vs. normal origin was significantly longer (5.2 +/- 0.5 vs. 3.5 +/- 0.4 min-1).
Mesenteric lymph was collected for 48 h from rats with aminonucleoside-induced nephrotic syndrome, receiving an intraduodenal infusion of a triacylglycerol emulsion. In nephrosis, the rates of lymph flow and triacylglycerol transport were approx. 2-fold higher, but the transport of total protein and
