Bicalutamide, a non-steroidal antiandrogen, produced dose-related increases in total cytochrome P450 (P450) and aldrin epoxidase, but had no effect on ethoxyresorufin O-deethylase, when administered for 10 weeks at 0, 25, 75 and 150 mg/kg/day to the male dog. 2.
Bicalutamide, administered as 14 daily oral doses (250 mg/kg) to groups of male rats, produced increases primarily in ethoxycoumarin O-deethylase and erythromycin N-demethylase, together with smaller increases in ethoxyresorufin O-deethylase and pentoxyresorufin O-dealkylase; these changes were reversible within 7 days.

APND and aldrin epoxidase (AE) were induced; EROD was not induced, although a hepatic CYP1A-like protein was detected in 1 kestrel dosed for 12 wk.
In quail, an acute dose of Aroclor 1254 caused significant liver weight increases, hepatic and renal EROD and aminopyrine n-demethylase (APND) induction, and dose-related hepatic and renal porphyria.

Ethoxyresorufin O-deethylase in Beta NF-induced microsomes and aminopyrine N-demethylase in PB-induced microsomes were most susceptible to inhibition by the test compounds.
In contrast, aldrin epoxidation and arylhydrocarbon hydroxylase in PB-and Beta NF-induced microsomes, respectively, were not inhibited by derivatives of AMDB.

Incubation of the 2,3,7,8-TCDD-induced microsomes with SKF-525A and alpha-naphthoflavone showed that both compounds inhibited DMAP N-demethylase, EROD and AHH and that alpha-naphthoflavone was the more potent inhibitor of all 3 microsomal monooxygenases. 2,3,7,8-TCDD treatment caused significant involution of the Bursa of Fabricius when administered at a dose level of 10 micrograms/kg for 3 days and this result confirmed the extreme sensitivity of the immature White Leghorn cockerel to the biologic and toxic effects elicited by 2,3,7,8-TCDD.

Within individual species, concentrations of cytochrome P-450 and b5 and activities of NADPH cytochrome c reductase, aldrin epoxidase, aminopyrine N-demethylase, ethoxycoumarin O-deethylase, microsomal and cytosolic stilbene oxide (epoxide) hydrolase and glutathione S-transferase were not different (P greater than .05) among the various hepatic lobes.

Despite these differences in t-permethrin susceptibility, microsomal oxidase activities toward surrogate substrate (aldrin epoxidase, and methoxyresorufin O-demethylase), cytochrome P450 content, and microsomal esterase activity toward alpha-naphthyl acetate did not differ significantly between the colonies.

As with the bioassay data, although significant differences were noted, a great deal of overlap was observed among the colonies for total cytochrome P450 content (difference of 2.2-fold between high and low value) aldrin epoxidation (3.6-fold) and cytosolic esterase (3.9-fold) activity.

Chlordimeform had no effect on the cytochrome P-450 content, aniline p-hydroxylase or glutathione S-transferase activities, but induced ethoxyresorufin-O-deethylase, ethoxycoumarin-O-deethylase and epoxide hydrolase activities and decreased aldrin epoxidase and aminopyrine N-demethylase activities.

The results of correlation analysis suggest that: there are important variations in the amounts of the three cytochrome P-450 isozymes measured, particularly P-450 (8) and P-450 (9); aldrin epoxidase, d-benzphetamine N-demethylase, and S-warfarin 4-hydroxylase activities are linked to cytochrome P-450 (5); aryl hydrocarbon (benzo (a) pyrene) hydroxylase and 4-nitroanisole-O-demethylase activities are linked to P-450 (8); hydroxylations at the 4'-, 6-, 7-, and 8-positions of R-warfarin are closely linked to each other but are not correlated with other measured monooxygenase activities or P-450 isozyme levels; and P-450 (9) is not related to any of the catalytic activities tested.

Although 3,3',4,4'-tetrachlorobiphenyl specifically induced certain drug-metabolizing enzyme activities, e.g. aryl hydrocarbon hydroxylase and UDP-glucuronosyltransferase (toward 4-nitrophenol), no highly significant correlations were found among the vitamin A levels and drug-metabolizing enzyme activities in the liver (aminopyrine N-demethylase, aryl hydrocarbon hydroxylase, aldrin epoxidase, microsomal epoxide hydrolase, UDP-glucuronosyltransferase toward 4-nitrophenol, glutathione transferase toward 1-chloro-2,4-dinitrobenzene and cytochrome P-450 content) as determined by multiple linear regression analysis.

Chicken liver microsomal erythromycin demethylase, a characteristic activity of rat pregnenolone-16-alpha-carbonitrile-inducible P450, was similar in developmental profile and induction to the immunodetected protein, with a high degree of augmentation at 1 day posthatch compared with that in the embryo and at 36 days posthatch; aldrin epoxidase, benzphetamine demethylase, ethylmorphine demethylase, and aminopyrine demethylase were more similar to each other in development and induction and were less well correlated with the immunodetected protein.

In parallel, in the case of 3-methylcholantrene induction the benz (a) pyrene hydroxylase and 7-ethoxyresorufin deethylase activities increase; phenobarbital induction causes a rise in the benzphetamine-N-demethylase and benz (a) pyrene hydroxylase activities.
The participation of phenobarbital-induced cytochrome P-450 in the metabolism of benzphetamine and aldrin in neonatal rats is much lower than in the adult ones.
