CHEMICAL AND MACROELEMENTAL COMPOSITION OF SKELETAL BONES AT DIET ENRICHED WITH PALM OIL IN RATS OF DIFFERENT AGES

Abstract

Nowadays, there is an undoubted link between the skeleton and adipose tissue at various functional levels; however, there is no complete information about skeletal morphogenesis in obesity at this time. The aim of the research was to establish the characteristics of the chemical and macroelemental composition of bones in rats of different ages with alimentary obesity. The experimen t was carried out on male rats of the two groups: group 1 - control, group 2 - rats receiving 6 weeks palm oil in dose of 30 g/day/kg. The periods of the experiment were 1, 10, 30 and 60 days after 6 weeks from the start of palm oil intake. The chemical composition of the bones was determined by weight and spectrophotometry methods. The use of palm oil in dose of 30 g/day/kg is accompanied b y an increase in the content of water, sodium and potassium, and a decrease in the content of organic and mineral substances, calcium and the ratio of calcium/phosphorus which increases with the duration of use of palm oil. These changes are most pronounced in adult and elderly animals, and to the least extent in juvenile rats.
