title: Changes in the biochemistry of the rat heart with increasing age.
abstract: Effects of increasing age on biochemical parameters of rat hearts have been summarized, as far as possible, in a descriptive, qualitative manner. Where available, the strain, age, and sex of rats have been included. Due to a lack of uniformity in expressing chemical components and enzyme activities found in rat hearts, it is inappropriate in a review of this type to advance hypotheses regarding the nature of biochemical changes that may be contributing to or be the results of aging processes.
