“…20]. Cal cium has also been shown to exhibit a bi phasic phenomenon comprising an active carrier-dependent mechanism and a second one showing linearity with the concentration of the metal ion [6]. A recent report by Adham and Song [ 1 ] also emphasizes the dis tinct mode of transport of Zn, Ca and Cu from rat intestine.…”

Effect of Vitamin B6 and B1 Deficiencies on the Intestinal Uptake of Calcium, Zinc and Cadmium

1982

View full text Add to dashboard Cite

A chronic vitamin B₆ deficiency in rats resulted in a non-specific increase (44–51 %) in the in vitro intestinal uptake of both essential (Ca and Zn) and non-essential toxic metal (Cd) ions, whereas an acute B₆-deficient state only affected the Zn uptake rate. In vitamin B₁ -deficient animals, a specific decrease (30–32%) was observed in Ca and Zn uptake with a 59% increase in the intestinal uptake of Cd. These altered metal ion uptake rates were probably not a result of hormonal disturbances due to the vitamin-deficient states.
