title: Redox status impairment in liver and kidney of prematurely senescent mice: effectiveness of DTS phytotherapeutic compound.
abstract: T-maze test-selected prematurely senescent mice (PSM) were allocated into two groups: (A) those given DTS (150 mg/kg) orally for 30 days and (B) untreated PSM with age-matched fast T-maze performers as control. After sacrifice, the liver and kidney were analyzed for catalase (CAT) activity, glutathione peroxidase (GPx), superoxide dismutase (SOD), malondyaldehyde (MDA), and plasma thiols. Untreated PSM showed decreased plasma thiols and tissue level of CAT, SOD, GPx, with higher MDA (P < 0.01 vs. fast performers), while DTS (Denshichi-Tochiu-Sen) significantly improved glutathione and cysteine (P < 0.05) and tissue concentration of the above parameters (P < 0.05). Such preliminary data suggest that DTS mitigated oxidative damage in PSM, with likely action on the cytoplasm and mitochondrial matrix.
