Two lines of rats bred to differ in their voluntary alcohol consumption — the alcohol-abstaining UChA rats and the alcohol-drinking UChB rats — differ in how effectively toxic acetaldehyde is removed during alcohol metabolism. UChB animals carry efficient variants of the aldehyde dehydrogenase 2 (ALDH2) genes and have active mitochondria, resulting in fast removal of acetaldehyde. UChA animals, in contrast, carry less efficient ALDH2 variants and less active mitochondria, which result in transient elevations of acetaldehyde levels after alcohol ingestion. Cross-breeding studies have demonstrated that the presence of active mitochondria inherited from UChB females can fully abolish the reduction of …

Background: Despite the numerous pharmaceutical applications of alcohols andglycols, the interspecies differences with respect to their pharmacokinetics (PK) arepoorly understood. The aim of this research was to use in-vivo and in-vitro approaches to compare and model the PK characteristics across various species.Methods: Appropriate published in-vivo studies (in different species) foralcohols and glycols were carefully selected. PK analysis was performed using (a) noncompartmental analysis and (b) compartmental modeling to estimate relevant dose-independent PK parameters. Next, six alcohols (methanol, ethanol, 1 -propanol, 1 -butanol, 1-hexanol, and 1-octanol), two glycols (ethylene glycol and propylene glycol)and one secondary alcohol (2-propanol) were examined as in-vitro …
