The passage of calcium and strontium across the gut of the anaesthetized goat

R. A. Gibbons, B. F. Sansom and R. Sellwood

1. The translocation of calcium and strontium across the intestine of the anaesthetized goat has been studied. It has been found to be unaffected by ouabain, by the absence of sodium, by a severely hypertonic environment and by heparin and chondroitin sulphate. Thus it is unlikely that, in the intact goat, the trans-mucosal sodium and calcium transport systems are interrelated.

2. The effect of sodium alginate both on the rate of absorption and the calcium/strontium discrimination ratio has been confirmed.

3. The movement of calcium ion in both directions across the intestinal mucosa has been studied and evidence for the active transport of calcium adduced.
