The difference of chows affects mouse physiological conditions.

ABSTRACT

Acetaminophen-induced liver injury in mice is a model system of human acetaminophen overdose and oxidative stress in vivo. The system is technically established, and we usually obtain severe liver damage in the treated mice; however, it is possible that the degree of liver damage is affected by the type of chow fed to mice. Thus, in this experiment, we investigated the effect of different chows on mice by comparing acetaminophen-induced liver damage, liver antioxidant level, and serum amino-acid concentrations. The results showed that differences in chows, even standard ones, affected mouse physiological conditions, with the response to oxidative stress greatly affected.
