Dietary intake and tissue concentration of fatty acids in omnivore, vegetarian and diabetic pregnancy.

The aim of this study was to determine the effect of fatty acid intake and insulin dependent diabetes on the fatty acid composition of maternal erythrocytes, the placenta and cord. Fatty acid intake (from food frequency questionnaire) and the fatty acid composition of maternal erythrocytes, the placenta and cord from pregnant vegetarians (n = 4) and insulin dependent diabetics (n = 5) was compared with pregnant omnivores (n = 10). There was a significantly lower intake of n-6 long chain polyunsaturated fatty acid (LCPUFA) (-75% P < 0.

[Study of the process of ACTH and insulin interaction with the plasmatic membranes of rat liver cells in vitro using luminescence methods].

The process of interaction of ACTH and insulin with plasmatic cellular membranes of the rat's liver and artificial lipid membranes (liposomes) was studied by the method of proper proteinic fluorescence and by using hydrophobic fluorescent probes. This process is shown to be attended by conformative readjustments of the membranous proteins and also by definite structural changes in the lipid phase of the membranes. In its action ACTH involves the hydrophobic layer of the lipid phase to a greater extent than does insulin.
