Inhibition of 7-ethoxyresorufin O-deethylation (EROD) in hepatic microsomes from castrated and entire male pigs by ANF (a), ellipticine (b) and furafylline (c). Assays were performed as described in the Experimental section. Values are expressed as percentages of activities in control incubations and are the mean of duplicates (differences between the duplicates were below 10%).
