Abstract

1) In rats fed a standard diet or a protein restricted diet the effect of acute and chronic ethanol administration on liver content of adenine nucleotides was studied. In the long-term experiments the total liver content of NAD and NADP was additionally determined. 2) a single oral ethanol load does not significantly influence the total adenine nucleotide content. Liver AMP content increases immediately following ethanol ingestion about 2-fold and remains elevated for 12 hours. ATP content and ATP/ADP ratio are significantly reduced within 30 minutes after ethanol administration. Both return to initial values after 2 hours adn decrease again thereafter. 3) The increase in the AMP content is dose dependent, i.e. it is more pronounced after small doses of ethanol and is not observed when blood ethanol concentrations are very high. The elevation of the AMP levels during ethanol oxidation is interpreted as a consequence of increased ATP consumption and of inhibition of citric acid cycle. 4) In animals fed nearly protein-free diet, total adenine nucleotide content and ATP content are distinctly reduced. An increase in AMP concentration is not observed in these rats where ethanol oxidation is markedly inhibited. 5) Chronic ethanol ap...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
