Abstract Title:
[Antioxidation of flavones of wheat germ on mammary tumor of rats].
Abstract:
The effect of flavonoids of wheat germ on mammary tumor of rats induced by 7,12-dimethylben(a) anthracene (DMBA) was investigated. Sprague-Dawley female rats (50 day-old, weighted around 176 g) were randomly divided into 4 groups. The negative and positive control group were fed on stoke diet. The high and low dose test groups were fed on diets with wheat germ flavonoids 10 and 2 g/kg respectively. Except rats in the negative control group, each rat was given DMBA 15 mg dissolved in 1.5 ml vegetable oil by tube feeding. After the administration of DMBA for 24 weeks, the incidence of tumor in the high dose test group was lower than that in the positive control group. The activity of blood and liver glutathione peroxidase (GSH-Px) and peroxidase dismutase(SOD) in the test groups was significantly higher than those in the positive control group, while the MDA level was significantly lower. The results suggested that the effect of flavonoids on inducing peroxidase might be one of the chemical prevention mechanisms on mammary tumors.
