Rapid31P NMR test of liver function

Abstract
The 31P NMR spectrum of perfused rat liver was found to be dependent on the exogenous carbon available to the tissue. When pyruvate was supplied to liver initially perfused with lactate, Pi decreased, phosphoenol pyruvate and phosphomonoesters increased, and nucieotide pools remained the same. It is proposed that these changes can be used to evaluate liver function. © 1988 Academic Press, Inc.
