title: Antioxidative effects of 7-hydroxy-3-methoxy-cadalene extracted from Zelkova serrata on 4-(methylinitros amino)-1-(3-pyridyl)-1-butanone-induced oxidative stress in A/J mice.
abstract: Effects of 7-hydroxy-3-methoxy-cadalene (cadalene) extracted from Zelkova serrata on 4-(methylinitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced oxidative stress were examined using A/J mice. NNK (65 microg/ml water) was orally administered to 20 mice for 7 weeks, followed by free feeding of a commercial diet, not containing cadalene, for 2 weeks. The control group was maintained without NNK and cadalene administration, and treatment groups with NNK and cadalene (6.25, 25, 100 mg/kg feed) feeding for 25 weeks. The glutathione concentration of cadalene-treated (65 microg/ml water) group was significantly higher than that of the group treated only with NNK (p < 0.05). The results of our study strongly indicate that cadalene exerts antioxidative effect on NNK-induced lung tumorigenesis in A/J mice.
