Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Influence of water hardness on gill accumulation and acute toxicity of aluminum in rainbow trout

Creator:: Bustaman, Sjahrul
Abstract:: Rainbow trout were exposed to aluminum at pH 7.25 and 8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃) for 96 hours in a continuous-flow system and mortality and aluminum accumulation in the gills were determined. Temperature, pH, and dissolved oxygen were measured daily for each treatment. Dissolved...

Ration and toxicant preexposure influence dieldrin accumulation by rainbow trout

Creator:: Shubat, Pam
Abstract:: Whole body accumulation and tissue distribution of dieldrin (HEOD1) in rainbow trout was studied through oral dose disposition tests and subchronic exposures via water (0.04 and 0.08 jig dieldrin/l) and/or diet (0.087 jig dieldrin/g fish/day). Growth and maintenance rations of 4 and 2% body weight/day were employed. Subchronic testing produced...

Thermally modulated biliary excretion of taurocholate in rainbow trout

Creator:: Kemp, Christopher J.
Abstract:: Biliary excretion of taurocholate in thermally acclimated rainbow trout was stimulated at higher environmental temperature (18 vs. 14 or 10° C)e Acute 4° C shifts in body temperature produced more pronounced changes in biliary excretion. Thermally modulated biliary excretion was negatively correlated with plasma half live of taurocholate. Absorption of...

Mechanisms affecting the bioaccumulation of dietary quinoline by rainbow trout (Salmo gairdneri)

Creator:: Dauble, Dennis D.
Abstract:: Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...

Vitellogenesis : a biomarker for estrogenic and antiestrogenic effects of organochlorines in rainbow trout

Creator:: Donohoe, Regina M.
Abstract:: Persistent organochlorines (OCs) bioaccumulate in aquatic biota and potentially impair reproduction via endocrine disruption. The present research evaluated estrogenic effects of the OCs, chlordecone (CD) and o,p'-DDT/DDE, and the antiestrogenicity of 3,4,5,3',4',5'-hexachlorobiphenyl (345-HCB) in juvenile rainbow trout, utilizing vitellogenesis as a biomarker. Vitellogenesis, estrogen regulated hepatic production of the yolk...

Dieldrin pretreatment does not induce hepatic microsomal and cytosolic epoxide hydrolase activities in rainbow trout (Oncorhyncus mykiss)

Creator:: Rosemond, Marie Victoire M.
Abstract:: Previous studies have shown that rainbow trout exposed to dieldrin via diet for 9 to 12 weeks increased biliary excretion of a subsequent dose of [¹⁴C]dieldrin by 500%. This was not explained by induction of the cytochrome P-450 (CYP) system involved in oxidative metabolism of these compounds. We hypothesized that...

Dieldrin stimulates biliary excretion of [14 C] benzo[a]pyrene polar metabolites but does not change the metabolite profile in rainbow trout (Oncorhyncus mykiss)

Creator:: Barnhill, Melanie L.
Abstract:: Feeding rainbow trout 0.3-0.4 mg dieldrinlkg/d for 9-12 weeks stimulated the biliary excretion of a subsequent dose of [¹⁴C]dieldrin by 500% and [³H]7,12- dimethylbenz[a]anthracene (DMBA) by 240%. In vitro work demonstrated that this interaction occurred without induction of the cytochrome P450 system, or other hepatocellular proteins involved in metabolism. The...

Assessing mechanisms of immunotoxicity for polycyclic aromatic hydrocarbons in rainbow trout (Oncorhynchus mykiss)

Creator:: Bravo, Claudia F.
Abstract:: During the past 30 years, numerous studies have focused on the toxicities of polycyclic aromatic hydrocarbons (PAH). Laboratory and field studies have helped elucidate the detrimental effects of these chemicals on growth, reproduction and immune response. Polycyclic aromatic hydrocarbons are in the priority list of chemicals to be studied by...

Antioxidant enzyme response in rainbow trout (Oncorhynchus mykiss) after subchronic exposure to an environmentally-relevant polycyclic aromatic hydrocarbon mixture

Creator:: Norby, Tyler S.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage. The aim of this study...
