A loss of acinar cells occurs with aging, while salivary production remains age-stable in healthy adults. It is hypothesized that a secretory reserve exists to preserve function despite a loss of acinar cells in normal aging. The purpose of this double-blind, placebo-controlled, crossover study was to determine age-related differences in ...

INTRODUCTION: How aging influences the secretion of saliva is not entirely clear. Postmortem studies have demonstrated that, with age, the parenchyma of the salivary glands is gradually replaced by fat, connective tissue, and oncocytes. However, functional studies among healthy individuals indicate that aging per se does not lead to a ...

The hypothalmo-pituitary thyroid axis, among various endocrine systems, undergoes physiological alterations associated with the ageing process. Directly age-related changes have to be distinguished from indirect modifications which are caused by simultaneous thyroidal or non-thyroidal illness or other physiological or pathophysiological states whose incidence increases with age. In summary, direct changes ...
