  • Title: [Effect of a phosphatidylcholine-enriched diet on the structural and functional parameters of rat liver microsomes].
    Author: Sharmanov TSh, Kurmangalinov SM, Abishev BKh, Aĭdarkhanov BB.
    Journal: Vopr Pitan; 1987; (3):39-41. PubMed ID: 3630041.
    Abstract:
    The authors studied the influence of the diet enriched with phosphatidylcholine on the structural-functional parameters of microsomes: lipid peroxidation activity, the levels of cytochromes b5 and P-450, microviscosity of the lipid phase of the membrane. In experiments in vivo it was found that phosphatidylcholine per se, not combined with antioxidants, did not show antioxidant properties. Biological effects of lecithin could be explained by its role as a catalyst of the monooxygenase system in the liver, based on the correlation (r = +0.8) between the high level of cytochrome b5 and the degree of eximerization of the fluorescent probe pyrene in the microsomes.
