Hepatic NF-E2-related factor 2 (Nrf2) expression. Nrf2 immunostaining in control mice (a) and mice receiving MC 400 mg/kg (b). Nrf2 immunoreactivity in CCl4-intoxicated mice (c) and mice secondary treated by MC at doses of 50 mg/kg (d), 200 mg/kg (e) and 400 mg/kg (f) and silymarin at dose of 400 mg/kg (g). Original magnification 400x. Representative results from 5 similarly treated mice. Each value represents the mean ± SD (n = 5). Measurement of the Nrf2 immunostaining intensity (h). Means sharing the same letter are not significantly different from each other (P < 0.05)
