Interaction of non-ionic surfactants with hepatic CYP in Prochilodus scrofa

Toxicology in Vitro, 2004
Cytochromes P450 (CYP) constitute a superfamily of hemeproteins that play a vital role in the metabolism of a wide variety of endogenous and xenobiotic compounds. Xenobiotic metabolism and the role of CYP are of particular interest in studies regarding the prevention of the damage caused by chemical pollutants.

Cryogenic preservation of spermatozoa from Prochilodus scrofa and Salminus maxillosus

Aquaculture, 1984
Abstract This paper reports an initial trial to cryopreserve semen from two freshwater South American fishes, the curimbata ( Prochilodus scrofa ) and the dourado ( Salminus maxillosus ). Motility and duration of motility were observed in curimbata and dourado fresh sperm.

Intestinal histology of a detritivorous (iliophagous) fish Prochilodus scrofa (characiformes, prochilodontidae)

Annales des Sciences Naturelles - Zoologie et Biologie Animale, 1998
Abstract The intestinal epithelium of Prochilodus scrofa, a freshwater teleost fish, was studied by means of light microscopic techniques. The samples were obtained from the initial, middle and terminal portions of each intestinal loop. The pyloric caeca are lined by a simple columnar epithelium with a small striated border and a very thick basal ...

Characterization of macrophage phagocytosis of the tropical fish Prochilodus scrofa (Steindachner, 1881)

Aquaculture, 2006
Measurements of in vivo and in vitro macrophage phagocytosis, using vital fluorescent dyes, were determined for Prochilodus scrofa in order to evaluate the effect of different stimuli on the health condition of this tropical fish. The Phagocytic Capacity (PC), Phagocytic Index (PI) and Germicide Capacity (GC) using Saccharomyces cerevisiae were ...

A new method to purify hepatic CYP1A of Prochilodus scrofa, a Brazilian freshwater fish

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2004
Cytochromes P450 constitute a superfamily of the phase I enzymes whose primary task is the detoxification of both endogenous and xenobiotic compounds. Fish, among non-mammalian species, have received great interest because they are a direct food source for humans as well as conveyors of toxic chemicals to human beings.

Patterns of gene expression during Prochilodus scrofa (Characiformes: Prochilodontidae) embryogenesis—I. Lactate dehydrogenase

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990
Abstract 1. 1. The patterns of expression of the lactate dehydrogenase loci in the differentiated adult tissues and in the early embryonic stages (0.8–180 hr post-fertilization) of curimbata, Prochilodus scrofa, were investigated. 2. 2.

Proximate, fatty acid and amino acid composition of the Brazilian freshwater fish Prochilodus scrofa

Food Chemistry, 1983
The proximate, fatty acid and amino acid compositions of the skinned fillets of the Brazilian freshwater fish Prochilodus scrofa were determined. The water, protein, lipid and ash contents (%) were: 76·5 ± 2·2, 20·4 ± 1·0, 2·7 ± 1·5 and 1·3 ± 0·0, respectively.

Myoendothelial junctions in blood vessels of a teleost (Prochilodus scrofa) pancreas and caeca

Protoplasma, 1985
Close contacts between endothelial and smooth muscle cells in teleost (Prochilodus scrofa) blood vessels are described for the first time in the present study. More frequently are seen finger-like, club-shaped or foot-like endothelial processes that come into close contact with the plasma membrane of a smooth muscle cell.

Hepatic metallothionein in a teleost (Prochilodus scrofa) exposed to copper at pH 4.5 and pH 8.0

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004
Copper accumulation and induction of metallothionein (MT) were investigated in the liver of juvenile Prochilodus scrofa exposed to copper (96 h-LC50) at pH 4.5 (LC50=98+/-0.8 microg Cu l(-1)) and pH 8.0 (LC50=16+/-0.5 microg Cu l(-1)) at 20 degrees C. No significant difference was found in copper accumulated in the liver at either pH. The ratio between

Gill Cellular Changes Induced by Copper Exposure in the South American Tropical Freshwater Fish Prochilodus scrofa

Environmental Research, 2002
The cellular changes in gill tissue induced by exposure to copper were studied in the tropical freshwater fish Prochilodus scrofa, with emphasis on chloride and pavement cells. Damage to gills included epithelial changes such as lifting, rupture, peeling of lamellar epithelium, lamellar fusion, hyperplasia, and cellular hypertrophy.
