Determination of cholesterol turnover rate by a one-and two-pool kinetic analysis.

The cholesterol turnover rate in rabbits with alimentary cholesterol atherosclerosis and in guinea-pigs with chronic vitamin C deficiency was studied by a one- and two-pool kinetic analysis. The one-pool analysis yielded exaggeraged values for the turnover rate, but the turnover rate differences between the control and experimental groups in the one- and the two-pool analysis were very similar. One-pool analysis can be used in initial studies to obtain preliminary data on the effect of nutritional, pharmacological and other factors on cholesterol turnover rate.
