摘要:Rats fed a bean diet develop a significant hypocholesterolemia. The catabolism of low density lipoprotein (LDL; d 1.019-1.063 g/ml) was studied in vivo and in vitro in the isolated perfused liver of rats fed either a casein or a bean diet. The clearance of LDL was significantly increased by 100% from 0.38 +/- 0.04 to 0.63 +/- 0.04 ml/h x 100 g body wt in vivo in the bean-fed rat. Similarly, the clearance of homologous and heterologous (human) LDL was also increased by 100% in the isolated perfused liver of bean-fed animals. Spleen, kidney, and hepatic cholesterogenesis was increased by 150% in these animals. Bile salt synthesis was increased from 1.54 +/- 0.02 to 2.84 +/- 0.09 nmol/min x g liver wt (P 1.060 g/ml lipoprotein fraction was unmodified by the bean diet. These data demonstrate that key metabolic pathways of hepatic cholesterol are modified in the bean-fed rat.( TRUNCATED AT 250 WORDS)
