Data represent the mean values and the standard deviation.
: only parameters with statistically significant findings are shown in table.
††: dose was reduced from 4000 to 3000 mg/kg bw/d on day 2.
and ∗∗P < 0.01, significance determined with Duncan's multiple range test or with Mann–Whitney test versus control.
: minimum and maximum levels reported as the range of historical control values.
