Age-related differences in NADPH-cytochrome P450 reductase activity in rat small intestine. Values are expressed as micromoles/min/mg of protein ± S.D. Significant difference at **P < 0.001 and *P < 0.005 versus control 2-week-old rats, at ‡ P < 0.005 and † P < 0.01 versus control 2-month-old rats, at filled circle P < 0.01 versus control 4-month-old rats, at filled diamond P < 0.01 versus control 20-month-old individuals. The differences in the enzymatic activity between the control and induced animals at the same age were not statistically significant, except for 20- and 28-month-old animals treated with ÎČ-naphtoflavone and phenobarbital, respectively. On account of that and also to maintain the lucidity, the graph shows all the values versus control groups only. Complete statistical analysis is shown in Table 4
