Abstract Curimbata, Prochilodus scrofa , were examined and selected for induced spawning with human chorionic gonadotropin (HCG). Intra-ovarian eggs were sampled and size composition was analyzed. With 21 females, two doses of HCG were applied at 10-h intervals, 5 IU and 10 IU per gram of total weight.

Interaction of non-ionic surfactants with hepatic CYP in Prochilodus scrofa
Toxicology in Vitro, 2004Cytochromes 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.

A new method to purify hepatic CYP1A of Prochilodus scrofa, a Brazilian freshwater fish
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2004Cytochromes 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.

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 ...

Myoendothelial junctions in blood vessels of a teleost (Prochilodus scrofa) pancreas and caeca
Protoplasma, 1985Close 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, 2004Copper 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

Abstract Three sample lots of curimbata ( Prochilodus scrofa ) captured from the Mogi Guacu River, Brazil, were analyzed for their lipid content and fatty acid composition. Separation into neutral and phospholipids was accomplished by silica column chromatography.

Testicular ultrastructure and morphology of the seminal pathway in Prochilodus scrofa.
Journal of submicroscopic cytology and pathology, 2002The seminiferous tubules of Prochilodus scrofa present a coiled morphological arrangement with intertubular anastomoses and unrestricted spermatogonial distribution. The structural pattern of the seminiferous tubules is cystic, with cysts formed by cytoplasmic prolongations of Sertoli cells.
