Chitooligosaccharides (COS), a kind of oligosaccharide made from chitin or chitosan, have been used a popular remedy for hangovers. In this study we investigated the in vitro effect of COS lactate salt on ethanol-induced cytotoxicity and the in vivo effect of short-term COS lactate salt feeding on ethanol-induced hangover. Pretreatment of HepG2 cells with COS lactate salt significantly reduced ethanol-induced cytotoxicity and suppressed generation of reactive oxygen species. In addition, COS lactate salt dose-dependently increased acetaldehyde dehydrogenase (ALDH) activity in vitro and reversed the ALDH inhibition induced by daidzin. Furthermore, oral administration of COS lactate salt (200 mg/kg) for 5 days significantly decreased the blood levels of alcohol and acetaldehyde in ethanol-treated mice. It was also demonstrated that hepatic mitochondrial ALDH activity was significantly increased in COS lactate salt-treated mice. Taken together, these findings indicate that COS lactate salt may have efficacy for the management of alcoholic hangovers.
