Abstract:
Dietary calcium and dietary phosphorus restriction were studied in chicks fed either cholecalciferol or 1α-hydroxycholecalciferol. Intestinal calcium absorption and calcium-binding protein of 1α-hydroxycholecalciferol-treated chicks remained unchanged under dietary calcium restriction, but increased under dietary phosphorus restriction. Kidney calcium-binding protein was not altered by dietary calcium restriction in chicks treated with either cholecalciferol or 1α-hydroxycholecalciferol, but increased under dietary phosphorus restriction independent of the vitamin D source. In contrast to the intestine, calcium-binding activity of the kidney was found to be poorly related to the calcium-binding protein concentration. It is suggested that kidney calcium-binding protein is regulated by a mechanism different from that of intestinal calcium-binding protein, and that its concentration in renal tissue is related to renal calcium excretion or plasma calcium level. © 1975.
