Effect of phenylhydrazine on the plasma lipids of albino rat

Red blood cell [14C]cholesterol exchange and plasma cholesterol esterifying activity of normal and sickle cell blood

The present study performed on density fractions of sickle and normal erythrocytes prepared on Stractan density gradient shows that dense erythrocytes have consistently decreased uptake of [14C]cholesterol from plasma in comparison to young, less dense erythrocytes. Plasma of sickle cell patients also shows a reduction in cholesterol-esterifying activity in comparison to normal controls. A possible effect of these processes in the increased cholesterol to phospholipid molar ratio of irreversibly sickled cells has been suggested.

Sex-dependence in triglyceride metabolism in response to dietary carbohydrates

In humans, as well as in mice, fed on high carbohydrate diets, there was a significant sex difference in the plasma tirglycerides in that males had higher levels than females. This was mainly due to the difference in their removal rate of circulating triglycerides in the animals of both sexes. In mice, males had higher levels of liver triglycerides as well as higher rate of incorporation of U- 14C-glucose into liver triglycerides when compared to females.
