Lymph flow expressed ml/h. Lymph flow was measured 1 h before (fasting) and hourly for 6 h after lipid/lutein infusion. The 4 groups of animals studied included 1) rats infused with 10 mg/kg 20% lutein in safflower oil (SO) suspension, 2) rats infused with 20 mg/kg 20% lutein in SO suspension, 3) rats infused with 40 mg/kg 20% lutein in SO suspension, and 4) rats infused with 80 mg/kg 20% lutein in SO suspension. Values are means + SE. Symbols for statistical difference: *20 vs. 10 mg/kg 20% lutein in SO, #40 vs. 10 mg/kg 20% lutein in SO, and ++80 vs. 10 mg/kg 20% lutein in SO.
