vitamin-d-2 and Tibial-Fractures

This study demonstrates the effect of essential fatty acid deficiency on the postnatal skeletal development in the rat. Four groups (n = 10) of newborn Wistar rats were fed diets containing high and low proportions of essential fatty acids in the lipid fraction until day 16 after birth. Suckled littermates were used as controls. X-ray and histological studies showed the occurrence of multiple pathological fractures of the long bones in 1-month-old rats fed a diet deprived of essential fatty acids. No effect of high (51,000 IU/100 g diet) and low (5,100 IU/100 g diet) concentrations of vitamin D2 was observed in our experiment. Thus, these data suggest the importance of essential fatty acids for bone pathology in the rat.
