ABSTRACT

The impact of food fat load on plasmic lipid transport system (LTS) was studied in persons with abdominal and gluteofemoral obesity by the standard fat test proposed by J. Patsch. The lipoprotein spectrum in abdominally obese patients was characterized by high atherogenicity of lipoprotein spectrum on an empty stomach aggravating under fat intake: prolongation of postprandial lipemia up to 6 hours with growing apoB and apoB/A1. Patients with gluteofemoral obesity differed from normal weight persons only by higher fasting values of triglycerides. They showed no atherogenic trend in changes in response to food fat.

ABSTRACT

Protein and lipid components of blood serum high density lipoproteins (HDL) responsible for their functional activity were studied before and after fat load in subjects with normal body mass and various types of obesity. Subjects with abdominal obesity compared with those with gluteo-femoral obesity and normal body mass initially had pronounced disturbances in components of HDL and their acceptor capacity. Fat load caused changes of HDL composition in all study groups. Postprandial effect in persons with normal body mass became obvious 6 hours after load while in those with excess mass it occurred earlier - 3 hours after fatty meal. In subjects with gluteo-femoral obesity this effect remained on the same level while in those with abdominal obesity it became more pronounced by hour 6. Contrary to subjects with normal body mass and gluteo-femoral obesity fat load induced changes of HDL components in persons with abdominal obesity were not associated with augmented acceptor capacity of HDL what could be considered as proatherogenic effect.

ABSTRACT

Subfractional spectrum of plasma low-density lipoproteins in people with normal body weight and patient with obesity was studied by gradient electrophoresis (3-12%) in polyacrylamide gel. Low-density lipoprotein subfractions in fasting patients with abdominal and gluteofemoral obesity were primarily presented by small particles (compared to people with normal body weight). The composition of low-density lipoprotein subfractions underwent most pronounced changes in patients with abdominal obesity after single fat load.
