Recovery of ³H-cholesterol from intraperitoneal injected macrophages in: a plasma, b liver and c feces from aerobically trained and sedentary mice. J774 macrophages were enriched with acetylated LDL and ³H-cholesterol and injected into peritoneal cavity of trained and sedentary C57BL/6N wild type mice. The radioactivity was determined in plasma and feces after 24 h and 48 h and in the liver after 48 h. The recovery of ³H-cholesterol was expressed as the percentage of injected dose/mL of plasma or percentage of injected dose/mg of tissue or feces. Data are expressed as mean values ± standard error
