The effects of chronic ethanol ingestion on ethanol binding to hepatic cytochrome P-450 and on certain hepatic and renal parameters in the "long sleep" and "short sleep" mouse

Abstract

Male mice selected for genetic differences in ethanol-induced sleep time, thereby designated long sleep (LS) an short sleep (SS), were treated with the Lieber-DeCarli liquid diet for 25 days. This chronic ethanol treatment produced an increase in liver/body weight and kidney/body weight in SS mice only. In addition, chronic ethanol treatment produced significant increases in both LS and SS treated mice in in vivo ethanol elimination, hepatic cytochromes P-450 and B5, NADPH cytochrome c reductase and hepatic and renal 7-ethoxycoumarin O-de-ethylase activity. Genotypic differences were observed in the magnitude of response of microsomal ethanol oxidation per mg of microsomal protein (SS greater than LS). Further, control LS and SS mice possessed substantially different activity of renal 7-ethoxycoumarin O-de-ethylase. Both lines exhibited similar induced renal 7-ethoxycoumarin O-de-ethylase activity after chronic ethanol ingestion. Ethanol binding spectra produced when ethanol was added to hepatic microsomes were examined using double reciprocal plots. Chronic ethanol ingestion produced genotypically related (LS greater than SS) increases in the absorbance change maximum per mg of microsomal protein. No significant changes in the...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
