Two forms of hepatic metallothionein were isolated and purified from rainbow trout injected intraperitoneally with cadmium chloride. Both forms showed similarities with mammalian metallothioneins, had a high cystein content (30 mol%), and were void of aromatic amino acids and histidine. The molecular weight was estimated to be about 6000 dalton for the

Avoidance of aluminum by rainbow trout
Environmental Toxicology and Chemistry, 2000Abstract Aluminum is the principal toxicant in fish in acid waters. The ability to avoid Al, particularly at low concentrations, would confer a considerable ecological advantage, but previous research into avoidance of Al has produced mixed results.

Methemoglobin in erythrocytes of rainbow trout
Comparative Biochemistry and Physiology Part A: Physiology, 1971Abstract 1. 1. The proportion of hemoglobin carried as oxidized (met-) hemoglobin was found to vary from 2·9 per cent in a wild stock to 17 per cent in a hatchery stock of rainbow trout. 2. 2. Hypoxia, anemia and the reticulocyte percentage (and consequently cell age) had little effect on the methemoglobin content. 3. 3.

A Rainbow Trout Lectin with Multimeric Structure
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997A novel lectin has been identified in rainbow trout serum and plasma. The lectin binds to Sepharose (an agarose polymer) in a calcium-dependent manner. Glucose, N-acetyl-glucosamine, mannose, N-acetyl-mannosamine, L-fucose, maltose and alpha-methyl-mannoside are good inhibitors of this binding, whereas glucosamine and D-fucose inhibits to a lesser ...

The cutthroat trout Y chromosome is conserved with that of rainbow trout
Cytogenetic and Genome Research, 2008Five genetic markers previously shown to be located on the sex chromosomes of rainbow trout <i>(Oncorhynchus mykiss) </i>were tested for linkage with the sex locus of Yellowstone cutthroat trout <i>(Oncorhynchus clarki bouvieri)</i> in a genetic cross created from a rainbow × cutthroat male hybrid.

The carcinogenicity of aflatoxin M1in rainbow trout
Food and Cosmetics Toxicology, 1975Summary Three groups, each initially of 250 trout, were fed a diet containing 5·8 ppb (b = 109) aflatoxin B1 (AFB1) or 5·9 or 27·3 ppb aflatoxin M1 (AFM1) for 16 months. A control group of 500 trout received the basal diet. In the early part of the study, a relatively high mortality rate resulted from underfeeding and infections. Toxin administration

Toxicokinetics of perfluorocarboxylate isomers in rainbow trout
Environmental Toxicology and Chemistry, 2009Abstract Perfluorooctanoate (PFOA) and other perfluorocarboxylates (PFCAs) are widely dispersed in the environment. Current and/or historical production of PFOA and fluorochemical precursors was conducted by telomerization and electrochemical fluorination (ECF).

Hepatic effects of acrylamide in rainbow trout
Toxicology and Applied Pharmacology, 1987Acrylamide effects on hepatic mixed function oxidase activity were examined in rainbow trout exposed to waterborne acrylamide monomer (0-50 mg/liter) for 14 days. Acrylamide doses of 25 mg/liter and higher produced reversible dose-related histological lesions in the liver characterized by necrosis around the central vein.

Genetic analysis of androgenetic rainbow trout
Journal of Experimental Zoology, 1991AbstractWe analyzed a number of genetic characteristics in androgenetic rainbow trout (Oncorhynchus mykiss) and their progeny. The androgenetic progeny of individual androgenetic males appeared genetically identical to each other based on eight enzyme loci. Their viability was no higher than that of androgenetic progeny of outbred males.

Erythrocyte volume distribution in rainbow trout
American Journal of Veterinary Research, 1985SUMMARY Reference mean corpuscular volume and volume heterogeneity values for erythrocytes of 23 rainbow trout were measured, using an electronic particle counter, and were analyzed, using a particle-size analyzer and microcomputer. The mean (± sd) erythrocyte count was 1.5 × 106 ± 0.16 × 106 cells/µl, the mean corpuscular volume was 346 ± 25 fl, and ...
