Correlations between endogenous prostaglandin E formation in the bone and spongiosa density.
The formation of prostaglandin (PG) E in the femoral head and the lumbar vertebral body of rats under ex vivo conditions after a linoleic acid (LA) rich diet (13.3 J%) has been compared to that of rats after an LA poor diet (0.5 J%). LA rich diet increased the formation of PGE in the lumbar vertebral body. In the femoral head were a similar, but statistically insignificant effect. The spongiosa density in the femoral head and the lumbar vertebral body increased after LA rich diet in contrast to LA poor fed rats. We conclude that the spongiosa density could be modulated by the LA content of the diet possible via alterations of endogenous PG biosynthesis.
