Abstract:
The liver mitochondrial redox state (the liver mitochondrial free NAD+/NADH ratio), which indicates hepatic energy charge, is known to parallel the ketone body ratio (acetoacetate/3-hydroxybutyrate) in liver tissue. Since the ketone body ratio in arterial blood was reported to correlate with that in liver tissue; the arterial ketone body ratio (AKBR) has been widely accepted as a useful measure of the liver function reserve. The liver mitochondrial redox state is known to decrease with the oxidation of ethanol in alcohol abusers. To evaluate whether AKBR reflected the effect of alcohol intake on the liver, AKBR was measured in normal controls (n=8), and patients with alcoholic liver injuries (n=14) and chronic active hepatitis (n=15). The mean AKBRs in the normal control subjects, in patients with chronic active viral hepatitis, and in those with alcoholic liver disease were 1.68±0.77, 2.22±1.02, and 1.55±0.79, respectively. Though the AKBR in patients with alcoholic liver disease tended to be lower than the other groups, there was no significant difference in AKBR among those three groups. In conclusion, this study demonstrated that AKBR was doubtful as an accurate parameter to estimate the changes in the liver mitochondrial redox state by alcoholic intake.
