Effects of probucol on plasma decay kinetics of 3H-cholesteryl hexadecyl ether (3H-CEt)/125I-N-methyl tyramine cellobiose (125I-NMTC) high-density lipoprotein (HDL) in mice. Mice (n=6 in each group) were fed the experimental diets for 2 weeks, and HDL turnover studies were performed as described in Methods on C57BL6/SW129 (A through C) and scavenger receptor class B type I knockout (D through F) mice. A and D, 3H-CEt and 125I-NMTC levels in plasma after injection. B and E, The CE-selective plasma fractional catabolic rate (FCR). C and F, The CE-selective uptake in the liver. cpm Indicates counts per minute. Significant differences, *P<0.05 (vs control).
