Thirty ml of 6% dextran (mol wt 70,000) was given intravenously daily to rabbits that were hypercholesterolemic from the ingestion of a 0.5%-cholesterol diet. Serum cholesterol concentrations were reduced from 990 ± 103 mg/100 ml to 676 it 79 mg/100 ml after 3 days and to 331 ± 35 mg/100 ml after 7 days of dextran treatment. With the cessation of dextran infusions, serum cholesterol levels rose...

The relatively long-lived positron emitters Cu (t1/2 = 12.7 h), Br (t1/2 = 16.2 h) and I (t1/2 = 4.18 d) are finding increasing applications in positron emission tomography (PET). For precise determination of their positron emission intensities, each radionuclide was prepared via a charged particle induced reaction in a “no-carrier-added” form and with high radionuclidic purity. It was then sub...
