Effect of an adzuki bean extract on hepatic anti-oxidant enzyme mRNAs in D-galactosamine-treated rats

In acute hepatic injury tests, an adzuki bean extract decreased D-galactosamine (GalN)-induced alterations in the serum alanine aminotransferase and aspartate aminotranferase activities to about 37% and 25%, respectively, although there were no significant differences in these activities between the GalN-treated group with the adzuki bean extract and the GalN-treated group without the adzuki bean extract. Furthermore, the hepatic glutathione peroxidase, glutathione reductase, and Mn- and Cu,Zn-superoxide dismutase mRNA levels in the GalN-treated group with the adzuki bean extract were higher than those in the control group and GalN-treated group without the adzuki bean extract.
