Abstract A method for estimating the cholesterol content of the serum low-density lipoprotein fraction (Sf0-20) is presented. The method involves measurements of fasting plasma total cholesterol, triglyceride, and high-density lipoprotein cholesterol concentrations, none of which requires the use of the preparative ultracentrifuge. Comparison of this suggested procedure with the more direct procedure, in which the ultracentrifuge is used, yielded correlation coefficients of .94 to .99, depending on the patient population compared.
THE SECOND report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel II, or ATP II) presents the National Cholesterol Education Program's updated recommendations for cholesterol management. It is similar to the first in general outline, and the fundamental approach to treatment of high blood cholesterol is comparable. This report continues to identify low-density lipoproteins (LDL) as the primary target of cholesterol-lowering therapy. As in the first report, the second report emphasizes the role of the clinical approach in primary prevention of coronary heart disease (CHD). Dietary therapy remains the first line of treatment of high blood cholesterol, and drug therapy is reserved for patients who are considered to be at high risk for CHD. However, the second report contains new features that distinguish it from the first. These include the following: Increased emphasis on See also pp 3002 and 3009.
The establishment of a vascular supply is required for organ development and differentiation as well as for tissue repair and reproductive functions in the adult1. Neovascularization (angiogenesis) is also implicated in the pathogenesis of a number of disorders. These include: proliferative retinopathies, age-related macular degeneration, tumors, rheumatoid arthritis, and psoriasis1,2. A strong correlation has been noted between density of microvessels in primary breast cancers and their nodal metastases and patient survival3. Similarly, a correlation has been reported between vascularity and invasive behavior in several other tumors4–6.
