Lipid metabolism in tissues and HDL were examined in daunomycin-induced nephrotic rats. 1) Daunomycin-induced nephrotic rats showed the decreased phospholipids, the increased cholesterol content in heart. Phospholipids, triglycerides and cholesterol content in brain, lung and spleen were similar in daunomycin-induced nephrotic rats and control rats. 2) Triglycerides content in hepatocytes was decreased in daunomycin-induced nephrotic rats. But, cholesterol esters content in hepatocytes was higher in daunomycin-induced nephrotic rats than control rats. 3) LCAT activity in serum was increased in daunomycin-induced nephrotic rats. 4) Apolipoproteins composition of HDL in daunomycin-induced nephrotic rats showed the increased apoA-I and the decreased apo E. These results show that the increased cholesterol esters in liver tissue are due to hepatocytes in daunomycin-induced nephrotic rats. The increased HDL cholesterol content may contribute to the increase of LCAT activity in daunomycin-induced nephrotic rats. The increase of LCAT activity in serum results in the increased apo A-I content in daunomycin-induced nephrotic rats. No direct evidence about the incorporation of HDL into liver is obtained from the present experiments and further study will be necessary to clarify this evidence.

D009404 Nephrotic Syndrome A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
