This study was designed to elucidate the effect of fermented blackberry drinks (BD) on alcohol metabolism and hangover in alcohol-treated rats. We showed that the administration of BD increased the activity of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in alcohol-treated rats. Moreover, the administration of BD reduced the serum alcohol and acetaldehyde concentrations in alcohol-treated rats. Furthermore, the administration of BD attenuated the levels of serum aspartate aminotransferase and alanine aminotransferase in alcohol-treated rats. Taken together, these results suggest that BD plays an important role in alcohol metabolism and liver function by reducing blood alcohol and acetaldehyde through the activation of ADH and ALDH in alcohol-treated rats and could be used as a functional anti-hangover drinks.

This study was conducted to investigate the effect of fermented blackberry drinks (BD) on carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Male Sprague-Dawley rats were randomly divided into four groups with 6 rats per group: control, $CCl_4$, $CCl_4$ plus BD $3ml\;kg^{-1}$, and $CCl_4$ plus BD $6ml\;kg^{-1}$. We found that the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly increased and the activity of antioxidant enzyme glutathione peroxidase (GPx) in the liver was decreased in rats treated with $CCl_4$ alone when compared with the control group. However, the administration of BD attenuated the levels of serum AST and ALT in $CCl_4$-treated rats. Moreover, the administration of BD significantly increased the activity of GPx in $CCl_4$-treated rat livers. Taken together, these results suggest that BD could protect the liver from $CCl_4$-induced hepatic damage.
