The observation that despite of removal of subjects from exposure source, their high calculi lead levels suggest that lead from internal body stores such as skeleton is also mobilized and circulated in physiological fluids during development of lithogenesis and deposit in growing calculi.

Bile acid synthesis is the major mechanism of bodily excretion of excess cholesterol. Tumor necrosis factor is a multifunctional cytokine with effects on lipid metabolism, coagulation, insulin resistance, and the function of endothelial cells lining blood vessels.
Bile acids, which are classically recognized for their involvement in dietary lipid absorption, are now known to be involved in many aspects of energy metabolism and disease processes in humans.
