Abstract: Serum triacylglycerol (TG) concentration is markedly elevated in Nagase analbuminemic rats (NAR) as compared to Sprague-Dawley rats (SDR) and reflects a high level of mainly VLDL. Hepatic production of triacylglycerol, as measured by the Triton-WR1339 infusion technique of impairing TG removal from blood, and plasma metabolic rate of pulse-infused [I-125]apo VLDL, were higher in NAR. However, contrary to previous reports, this elevated TG production could not be controlled by previous treatment of NAR with (i) bovine albumin infused intra-arterially or into the peritoneal cavity, or with (ii) dextran (Mol.wt. 73 500) injected intraperitoneally. Albumin administration expanded the plasma volume and could explain the apparent reduction of blood lipids found by others. Nonetheless, intraperitoneal dextran, as compared to saline, reduced the plasma cholesterol concentration regardless of the variation in the hematocrit level and thus, by raising the osmotic pressure of blood might regulate the metabolism of cholesterol-rich lipoproteins such as LDL and HDL in NAR.
