[Structural modifications of the sciatic nerve in rats on different fat diets (author's transl)].

The influence of dietary lipid components on fatty acids content of the sciatic nerve was studied in rats. Rats of both sexes were divided into three groups according to diet: 1. standard diet; 2. standard diet enriched with various seed oils; 3. colza oil-enriched diet. Six animals from each group (3 males and 3 females) were killed after 15, 30, 60 and 90 days, respectively, of controlled feedings. Their sciatic nerves were immediately removed and freeze-dried. Lipid extracts were prepared from each sample gas chromatography tests were made on the esterified fats. The results obtained show that there is a change in the fatty acids of the sciatic nerve lipids in rats on low fat diets, while the amount of phospholipids remains the same.
