11. It was shown that dietary phosphate does not interfere with the protective effects of dietary calcium on luminal solubility and lytic activity of fatty acids and bile acids. 12. These protective effects of calcium are not inhibited by a fourfold increase in dietary phosphate. 13. This probably reflects the shorter period of monitoring rather than any protective effect of the gastroscopy on cardiac rhythm. 14. Initially, we postulated that any protective effect of ursodeoxycholic acid against gall stone recurrence would be mediated through changes in biliary cholesterol saturation. 15.
