[Study on screening differentially expressed genes in mice livers by silver staining DD-PCR].

Aim: To screen swimming-fatigue related genes in mice and lay theoretic basis for researching the molecular mechanism of fatigue.

Methods: 30 male BALB/c mice (20 +/- 2g) were divided into control group, dipping in water group and swimming-fatigue group respectively. After fatigue for swimming in swimming-fatigue group, with control group and dipping in water group, liver tissues in mice were collected.
