Adenine nucleotides of myocardium from rats treated with isoproterenol and-or Mg- or K-deficiency.

Abstract

The contents of adenine nucleotides of myocardium from rats treated with isoproterenol and/or dietary Mg- or K-deficiency were measured. And also, the fatty acid composition of phospholipid fractions of liver from rats fed control diet, a Mg- and/or K-deficient diet for 20 days is pre-sented.Both the administration of isoproterenol and the dietary Mg- or K-deficiency produced the significant decrease of ATP. However, the re-lative ratio among ATP, ADP and AMP did not show any remarkable changes.By feeding a diet containing low K and/or Mg, the fatty acid compositions of phospholipids from rat liver were changed.
