The synergistic effects of combining fish oil (FO) diet, which reduces thromboxane A production, with the free radical scavenger, dimethylthiourea (DMTU), were evaluated in acute adriamycin nephrosis, because proteinuria in adriamycin nephrosis is mediated by increased renal thromboxane A and free
o-Benzyl-p-chlorophenol (BCP) is a major household and industrial germicide. Its prechronic toxicity was evaluated in male and female F344 rats and B6C3F1 mice. Treatment was by gavage in corn oil. BCP was slightly toxic after acute oral exposure, with high mortality at 4000 and 2000 mg/kg in rats
In the studies described here, we have examined the sex-specific sensitivity of rat kidney to d-limonene. At 24 hr after an acute dose of 200 mg d-limonene/kg body weight administered to adult male and female Fischer 344 rats by oral gavage, an increase in the incidence and severity of hyaline
Groups of young adult male Fischer-344 rats given the vehicle (corn oil) or either decalin or d-limonene at dose levels of 75, 150 or 300 mg/kg body weight by a single daily gavage on 5 days/wk were killed on study days 6 or 27, approximately 24 hr after the fifth or 20th dose, to determine whether
Livestock grazing lush Kochia scoparia (L.) Schrad, sometimes experience BW loss, hyperbilirubinemia, photosensitization, and polyuria. Animals fed kochia hay may exhibit milder or negligible signs of toxicosis but fail to utilize nutrients efficiently. To characterize early aspects of kochia
A 13-week subchronic study was conducted by administering hexachlorocyclopentadiene ( HCCP ) in corn oil by gavage to groups of ten male and ten female F344 rats at doses of 150, 75, 38, 19, 10 or 0 mg kg-1, and to groups of ten male and ten female B6C3F1 mice at doses of 300, 150, 75, 38, 19 or 0
Toxicology and carcinogenesis studies of n-butyl chloride (greater than 99.5% pure), a solvent as well as an alkylating agent, were conducted by exposing groups of F344/N rats and B6C3F1 mice to n-butyl chloride in corn oil by gavage for 14 days, 13 weeks, and 2 years. In the 14-day studies, no
Trichloroethylene (TCE) is an industrial solvent used for vapor degreasing and cold cleaning of fabricated metal parts. TCE has also been used as a carrier solvent for the active ingredients of insecticides and fungicides, as a solvent for waxes, fats, resins, and oils, as an anesthetic for medical
Benzofuran is used as an intermediate in the polymerization of coumarone-indene resins found in various corrosion-resistant coatings such as paints and varnishes, in water-resistant coatings for paper products and fabrics, and in adhesives approved for use in food containers. NTP Toxicology and
Toxicology and carcinogenesis studies of chlorodibromomethane (greater than 98% pure), a trihalomethane formed after chlorination of water supplies, were conducted by administering this test chemical in corn oil gavage five times per week for 104 weeks to groups of 50 male and 50 female F344/N rats
oxicology and carcinogenesis studies of HC Red No. 3 (97% pure), a semipermanent hair dye, were conducted by administering the chemical in corn oil by gavage for 105 weeks to groups of 50 male and 50 female F344/N rats and for 104 weeks to groups of 50 male and 50 female B6C3F1 mice. The dosage
Toxicology and carcinogenesis studies of technical-grade 3-chloro-2-methylpropene (containing 5% dimethylvinyl chloride), a widely used insecticide and a chemical intermediate, were performed on F344/N rats and B6C3F1 mice. In the 13-week studies, 50%-100% mortality occurred in groups of male and
4-Vinyl-1-cyclohexene diepoxide is used a chemical intermediate and as a reactive diluent for diepoxides and epoxy resins. Toxicology and carcinogenesis studies were conducted by administering 4-vinyl-1-cyclohexene diepoxide (97% pure) in acetone by dermal application to individually housed F344/N
Methylene-bis-2,6-diisopropylaniline (MDPA), a chemical having potential application as a polyurethane chain extender or an epoxy curing agent, was administered daily by gavage to male Fischer 344 rats and male Syrian golden FVG hamsters. Rats were administered MDPA at 10.5, 21.0, 42.0, 63.0, or
The acute rat oral LD50 for tetramethylsuccinonitrile (TMSN) is 38.9 +/- 7.4 mg/kg. A series of three 90-day subchronic toxicity studies were conducted with Sprague-Dawley-derived albino rats. In each study, rats were administered corn oil solutions of TMSN by intubation. In the first study, groups
