Effect of aqueous TA extract on the GST levels in CCl4 induced hepatic and renal damages in mice. Aqueous extract of TA was administered orally 7 days prior to CCl4 treatment (1 ml/kg body weight). For experimental detail, see the materials and methods. Left panel shows the effects of the extract on liver and right panel shows that on the kidney against CCl4 induced GST levels. Cont: GST level in normal mice, CCl4: GST level in only CCl4 treated mice, TA+CCl4: GST level in which extract was given at a dose 50 mg/kg body weight prior to CCl4 administration, VitE+CCl4: GST level in which vitamin E was given at a dose of 200 mg/kg body weight prior to CCl4 administration. Each column represents mean ± SD, n = 6; (P* < 0.01, P** < 0.001).
