1. 3,3',4,4'-tetrachlorobiphenyl (PCB 77), but not hexachlorobenzene, induced liver microsomal cytochrome P-450 (Cyt P-450), ethoxycoumarin-O-deethylase (ECOD) and ethoxyresorufin-O-deethylase (EROD) in rainbow trout. Maximum induction was observed in a PCB 77 injected group of fish (1.0 mg/kg, i.p.

Environmental Toxicology and Chemistry, 1994
AbstractImmune function and hepatic MFO activity were examined in adult and nestling starlings administered a synthetic PAH, 7,12-dimethylbenz[a]anthracene (DMBA). Methods used to examine the starling immune system included immunopa-thology, macrophage phagocytosis, lymphocyte blastogenesis to concanavalin A, and hemagglutination of sheep erythrocytes (

Annual Review of Physiology, 1983
The microsomal steroidogenic enzymes catalyze reactions important in determining both the quantity and the identity of glandular secretory prod ucts. By determining cell function, changes in the rates of these reactions can effect differentiation. The recognition of these control points in steroid hormone biosynthesis lagged because major research ...

Microsome-mediated metabolic activation of aflatoxin B1 (AFB1) and benzo[a]-pyrene (BP), as determined by the in vitro formation of DNA binding metabolites, was studied, using hepatic microsomes from untreated, phenobarbital (PB)-treated and 3-methylcholanthrene (MC)-treated male rats.

AbstractThe polycyclic aromatic hydrocarbon 7-isopropyl−1-methylphenanthrene (retene) induces mixed function oxygenase (MFO) activity of fish. Bile levels of retene and its metabolite(s) were measured in relation to exposure time, exposure concentration, and induction of MFO activity.

We compared the uptake of water-accommodated fractions of Alaska North Slope crude oil in pre- and post-spawn herring (Clupea pallasi) and the resulting induction of mixed function oxygenase activity. Both groups of herring accumulated significant quantities of polycyclic aromatic hydrocarbons in muscle tissue.
