Effect of grape skin and seeds on hydroxyproline contents in the liver of rats treated with DMN

DMN was intraperitoneally given at 10 mg/kg on 3 consecutive days per week for 4 weeks to each group except normal group.

DMN, DMN alone; K10, 10% diet of grape skin without DMN; DK10, 10% diet of grape skin with DMN; S10, 10% diet of grape seeds without DMN; DS10, 10% diet of grape seeds with DMN

Values are the mean ± SD of rats. Liver samples were hydrolyzed and assayed for hydroxyproline.

Statistical significance: ^**P < 0.01 vs. DMN, and ^###P < 0.001 vs. normal, respectively
