Brief Summary:

Researchers plan to study the fat-rich particles, called lipoproteins, which circulate in the blood. This study is designed to improve understanding of normal, as well as abnormal, lipoprotein metabolism and the role it plays in the development of hardening of the arteries (atherosclerosis).

Patients participating in this study will receive an intravenous (directly into the vein) injection of a small amount of specially prepared amino acids. The amino acids being injected are the same amino acids present in a normal diet. The amount of amino acid given will be less than the amount eaten in a protein-rich meal. The amino acids will be labeled with nonradioactive heavy isotopes which are also present in the environment n low amounts.

Patients participating in the study will be required to have blood samples taken, and provide urine samples throughout the course of the study. In addition, patient will be required to follow a specially formulated diet. Patients will be weighed throughout the course of the study.


Condition or disease
Healthy Hyperlipoproteinemia

Detailed Description:
Apolipoproteins regulate the metabolism of lipids and lipoproteins in plasma of humans. In order to investigate the roles of apolipoproteins in these processes, we plan to quantitate the kinetics of the metabolism of apolipoproteins utilizing nonradioactive isotope labeled amino-acids.

Study Type : Observational
Enrollment : 90 participants
Official Title: Lipoprotein Metabolism in Normal Volunteers and Dyslipoproteinemic Patients (Stable Isotopes)
Study Start Date : December 1987
Study Completion Date : March 2002
