  • Title: Effect of pectin on cholesterol distribution in the lipoproteins of streptozotocin-diabetic rats fed cholesterol diet.
    Author: Bobek P, Chorváthová V.
    Journal: Physiol Bohemoslov; 1984; 33(3):230-6. PubMed ID: 6591217.
    Abstract:
    In rats fed a semisynthetic diet, streptozotocin-induced diabetes [45 mg/kg, 17 days] led to hypertriglyceridaemia [6.4 mmol/l], to a marked increase in the proportion of plasma cholesterol present in the very low density lipoproteins [VLDL] [to 40 %] and to a decrease in the amount present in the high density lipoproteins [HDL] [to 34 %]. The addition of 0.25 % cholesterol to the above diet led in healthy rats to hypercholesterolaemia [4.3 mmol/l] and to similar changes in the distribution of cholesterol in the lipoproteins. In diabetic rats, the same diet led to pronounced hypertriglyceridaemia [13.8 mmol/l] and hypercholesterolaemia [18.9 mmol/l], while the proportion of HDL-borne plasma cholesterol fell still further to 6 % and rose in the VLDL to 70 %. The addition of pectin to the diet in 6 % concentration markedly inhibited triglyceridaemia [3.3 mmol/l] and cholesterolaemia [4.4 mmol/l] and raised the proportion of HDL plasma cholesterol to 47 %.
