(a) The white bars show the effect of DIC (0.316 mg/kg) and CAF (1 mg/kg) when administered separately by oral route; the black bar shows the effect of the drug combinations at the indicated doses. (b) The white bars show the effect of DIC (10 mg/kg) and CAF (1 mg/kg) when administered separately by oral route; the black bar shows the effect of the drug combinations at the indicated doses. For each treatment the mean of an n = 6 ± S.E.M. was plotted on the graph.
