Effects of Intralipid Versus Olive Oil Infusions on Endothelial Function, Immune Function, Inflammatory Markers
Summary
Recent evidence suggests that increased levels of a circulation fat (free fatty acids or FFAs) can cause high blood pressure and cardiac complications. Intralipid is the only type of fat approved by the FDA for clinical use. It is usually used as nutrition support in malnourished patients. The investigators' preliminary studies indicate that Intralipid results in a significant rise in blood pressure, blood vessel stiffness, and inflammation in obese subjects. Olive oil can also be used as nutrition support. The effect of olive oil intravenous (IV) on blood pressure and inflammation is not known. In this study, the investigators will compare the effect of Intralipid and olive oil on blood pressure, blood vessel stiffness and inflammation in healthy subjects. The investigators hypothesize that Olive oil emulsions will result in less vascular changes and less inflammatory response than Intralipid solutions. Accordingly, the investigators propose a systematic evaluation of the effects of Intralipid, olive oil and normal saline on blood pressure, endothelial function (vascular stiffness), inflammation in normal subjects.
A group of obese subjects will be admitted to the Clinical Research Center on 3 occasions. Subjects will receive repeated infusions of Intralipid, ClinOleic, and normal saline at 20 ml/hour for 24 hours.

Infusion Pumps
Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agents and other drugs in thromboembolism, heart disease, diabetes mellitus (INSULIN INFUSION SYSTEMS is also available), and other disorders.
Perinatology

Haloarcula
A genus of HALOBACTERIACEAE distinguished from other genera in the family by the presence of specific derivatives of TGD-2 polar lipids. Haloarcula are found in neutral saline environments such as salt lakes, marine salterns, and saline soils.
Halomonadaceae
A family of gram-negative, moderately halophilic bacteria in the order Oceanospirillales. Members of the family have been isolated from temperate and Antarctic saline lakes, solar salt facilities, saline soils, and marine environments.
Polyuria
Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
