ABSTRACT
The authors investigated in rats with dietarily-induced obesity certain biochemical parameters of the blood plasma as well as body and organ weights during the dynamic and the static phase of obesity development. They determined total cholesterol, total protein, albumin, creatinine, urea nitrogen and transaminases. After 4-5 weeks, the animals on a high-diet (50% of fat) had body weights which were, on an average, by 90% higher than those of the control animals. This difference persisted during the static phase. In the animals on a high-fat diet, body length was greater. The high-fat diet (which contains a great proportion of sunflower oil) leads to a decrease of the plasma cholesterol level in obese rats. The plasma-protein bodies, creatinine and urea nitrogen values as well as those for transaminases permit, as parameters for function and damage, to draw conclusions as to kidney and liver damages in the animals on high-fat diet. There were no differences in plasma protein between the control and experimental animals. On the contrary, obese rats showed in some cases high creatinine concentrations during the dynamic phase. Differences in urea nitrogen were not observed between the two groups of animals. Increases in alanine aminotransferase were found in the animals on high-fat diet as a manifestation of fatty degeneration of the liver. A synopsis of weight curves, biochemical parameters and histological findings permits the conclusion that, besides of dietarily-induced metabolic alterations, no additional organic lesions occurred during the present animal experiment on dietarily-induced obesity.
