Sixty minutes of normothermic ischemia in the rat liver: correlation between adenine nucleotides and bile excretion.

The effect of 60 min of normothermic liver ischemia on cellular levels of adenine nucleotides (ATP, ADP, and AMP), energy charge (EC), and bile excretion was studied. Following ischemia the concentration of ATP was reduced to 12% of preischemic and control values within the first 10 min and remained low during the remaining ischemic period. EC values were also low. During 120 min of reperfusion, ATP increased to 34% of the ATP level found in the control group. EC values increased immediately to reach values not significantly different from those of control animals. Bile flow was nonexistent during ischemia and increased during reperfusion. The increase paralleled those of ATP and EC. Bile flow seems to reflect the degree of liver ischemia and may be used as a functional parameter.
