Brief Summary:
1) to test HDL function comprehensively in healthy and diseased individuals; 2) to evaluate if this test correlates with cardiovascular risk, independent of traditional risk factors; 3) and to differentiate effects of lipid-modifying or antiatherosclerotic drugs on HDL function and composition

Primary Outcome Measures :
  1. Cholesterol efflux capacity (%) [ Time Frame: Change of HDL functions from baseline to 8 weeks ]
    [3H-cholesterol (µCi) in medium containing HDL/(3H-cholesterol {µCi} in medium containing HDL+µCi of 3H-cholesterol {µCi} in cells)] x 100

  2. Endothelial NO production (Arbitrary unit) [ Time Frame: up to 8 weeks ]
    measured with nitrate assay kit and expressed as relative amount compared to control (no HDL treatment sample)

  3. VCAM-1 expression (Arbitrary unit) [ Time Frame: up to 8 weeks ]
    western blotting of VCAM-1 protein and expressed as relative amount compared to control (no HDL treatment sample)

  4. ROS generation (Arbitrary unit) [ Time Frame: up to 8 weeks ]
    fluorescence intensity measurement using dichlorodihydrofluorescein diacetate and expressed as relative amount compared to control (no HDL treatment sample)


Secondary Outcome Measures :
  1. ApoA-I [ Time Frame: Change of HDL associated proteins from each patient at baseline and at 8 weeks ]
    quantitation of intensity of western blot and expresses as relative amount to control (no HDL treatment sample)

  2. ApoA-II [ Time Frame: Change of HDL associated proteins from each patient at baseline and at 8 weeks ]
    quantitation of intensity of western blot and expresses as relative amount to control (no HDL treatment sample)

  3. ApoC-I [ Time Frame: Change of HDL associated proteins from each patient at baseline and at 8 weeks ]
    quantitation of intensity of western blot and expresses as relative amount to control (no HDL treatment sample)

  4. ApoC-II [ Time Frame: Change of HDL associated proteins from each patient at baseline and at 8 weeks ]
    quantitation of intensity of western blot and expresses as relative amount to control (no HDL treatment sample)

  5. ApoC-III [ Time Frame: Change of HDL associated proteins from each patient at baseline and at 8 weeks ]
    quantitation of intensity of western blot and expresses as relative amount to control (no HDL treatment sample)
