Mixed-function oxygenase system and benzo[a]pyrene metabolism in echinoderms

Marine Environmental Research, 1989
Abstract A comparative study on the presence of a mixed-function oxygenase (MFO) system was carried out on four echinoderm species: the asteroids Asterias rubens and Marthasterias glacialis , an echinoid Echinus esculentus and a holothurian Holothuria forskali . In A.

Responses of channel catfish to xenobiotics: Induction and partial characterization of a mixed function oxygenase

Archives of Environmental Contamination and Toxicology, 1983
The effects of the environmental pollutant benzo(a)pyrene (BP) were assessed on the hepatic mixed function oxygenase system (MFO) in the channel catfish,Ictalurus punctatus. Initially, the optimum conditions were established for measuring hepatic MFO in this species of fish.

Presence of mixed function oxygenase in some marine invertebrates

Thalassia Jugoslavica, 1983
We could confirm MFO activity in crabs at the levelswhich are low compared to the activity levels found in vertebrates. MFO inducibility by Diesel-2 oil and benzo(a)pyrene was demonstrated in crab Pilumnus spinifer.

EFFECTS OF 7,12-DIMETHYLBENZ[a]ANTHRACENE ON IMMUNE FUNCTION AND MIXED-FUNCTION OXYGENASE ACTIVITY IN THE EUROPEAN STARLING

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 (

Responses of mixed-function oxygenase and antioxidase enzyme system of Mytilus sp. to organic pollution

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1991
1. Mixed-function oxidase (MFO) system components (cytochrome P-450, "418-peak", cytochrome b5 and NADPH-cytochrome c(P-450) reductase) and inducible antioxidant enzymes (catalase, superoxide dismutase (SOD), glutathione peroxidase (GPX) and DT-diaphorase) has been determined in digestive glands of mussels (Mytilus galloprovincialis) collected from ...

SEASONAL VARIATION IN THE MIXED-FUNCTION OXYGENASE SYSTEM AND ANTIOXIDANT ENZYMES OF THE MUSSEL MYTILUS GALLOPROVINCIALIS

Environmental Toxicology and Chemistry, 1995
Abstract Seasonal variations in the mixed-function oxygenase (MFO) system components (cytochrome P450, “418” peak, and NADPH-cytochrome c[P450] reductase) and antioxidant enzymes (catalase, superoxide dismutase [SOD], glutathione peroxidase [GPX], and DT-diaphorase) of the mussel Mytilus galloprovincialis have been evaluated.

The interplay between mixed function oxygenases and DNA alteration under PAH pollution

Marine Environmental Research, 1985
Abstract Our experience in DNA alteration assessment tells us that aquatic vertebrates, in general, and also some of the invertebrates, by living in polluted areas acquire altered DNA; DNA alterations being defined either as single-strand breaks, and/or alkali sensitive or single-strand specific nuclease-cleavable sites (sse).
