Previous works clearly showed that chronic contamination by 137cesium alters vitamin D metabolism. Since children are known to be a high-risk group for vitamin D metabolism disorders, effects of 137Cs on vitamin D biosynthetic pathway were investigated in newborn rats. The experiments were performed in 21-day-old male offspring of dams exposed to 137Cs in their drinking water at a dose of 6,500 Bq/l...
Uranium is a natural radioactive heavy metal. Its toxicity has been demonstrated for different organs, including bone, kidney, liver and brain. Effects of an acute contamination by depleted uranium (DU) were investigated in vivo on vitamin D3 biosynthetic pathway. Rats received an intragastric administration of DU (204 mg/kg) and various parameters were studied either on day 1 or day 3 after contamination...
