Age features of ultrastructure of biomineral of hip bone in white rats after excessive palm oil intake and administration of Garcinia cambogia extract

Abstract

Objective: Analysis of ultrastructure of a biomineral of hip bones (HB) in white rats in alimentary obesity caused by excessive refined palm oil (PO) intake as well as developing a method for correction of detected changes using Garcinia cambogia extract (GCE).Methods: 216 male rats (juvenile, pubertal, and senile) were used. Animals received PO at a dose of 30 g/kg a day and GCE at a dose of 0.25 g/kg a day 6 weeks later after the start of PO intake. The ultrastructure of PO biomineral was analyzed by X-ray scattering technique.Results: When juvenile rats took PO, the sizes of crystallites were 4.35% larger than control figures by the 60th day, and coefficient of micro-texturing was 4.72% lower. In pubertal rats, these deviations were 6.14 and 5.05%; in senile rats, they were 5.68 and 7.43%, respectively. When administrating GCE, in juvenile rats, the sizes of crystallites were 3.82% lower than values of group without correction by the 60th day, and coefficient of micro-texturing was 4.67% higher. In pubertal rats, these deviations accounted for 5.52 and 8.03%; and in senile rats, they were 4.34 and 5.56%, respectively.Conclusion: Consumption of PO at a dose of 30 g/kg a day is accompanied by destabilization of HP biomineral in white rats. Administration of GCE at a dose of 0.25 g/kg a day reduces the effect of PO on the ultrastructure of HB biomineral from 30 to 60 days in juvenile and pubertal rats, in senile rats – from the 60th day.
