  • Title: [Effects of cadmium on vitamin D function involved in the regulation of phosphorus-calcium metabolism].
    Author: Volkova NA, Karpliuk IA.
    Journal: Vopr Pitan; 1993; (5):53-7. PubMed ID: 8042315.
    Abstract:
    The role of vitamin D in regulation of phosphoric-calcium metabolism was evaluated in conditions of experimental cadmium intoxication induced by daily dietetic intake (100 micrograms/kg for 8 months) of cadmium in parallel with intake of calcium in diverse amounts. Daily requirements in vitamin D were provided in different groups of animals either with ergocalciferol (D2) or 24,25-dihydroxycholecalciferol (0.25 microgram per animal). The results of the trial suggested that despite regular supply of ergocalciferol, renal damage induced by cadmium intoxication was associated with phosphoric-calcium metabolic derangement which is likely to result from defects in renal synthesis of active vitamin D form. This was confirmed by the fact that the change of ergocalciferol for 24,25-dihydroxycholecalciferol did not produce any noticeable shifts in the phosphoric-calcium metabolism.
