Plasma and Red Cell Cholesterol

[摘要] The experimental production of hypercholesteremia in rabbits by three independent methods—namely, high-fat feeding, cortisone injection, and Tween-80 injection—results in an elevated plasma total cholesterol, whereas the total RBC cholesterol remains constant. Previous work on plasma and red cell cholesterol in humans has been substantiated. Normal total plasma and red cell cholesterol values are 187 ± 32 and 129 ± 20 mg.%, respectively.Elevated plasma total cholesterol occurring in coronary arteriosclerosis, diabetes, nephritis, hypothyroid, Hodgkin's disease, and obesity does not affect the erythrocyte levels. Elevated erythrocyte total cholesterol levels occur in sickle cell and pernicious anemia accompanied by slightly sub-normal plasma levels. A hypothesis is advanced to explain the variability of plasma cholesterol and the relative constancy of red cell cholesterol.
