As part of a collaborative project, 4-vinylcyclohexene diepoxide (VCD), an ovarian toxicant, was intraperitoneally administered to female Sprague-Dawley rats at 0, 5, 20 or 80 mg/kg from 2 weeks prior to mating to Day 7 of gestation. At necropsy, the number of implanted embryos, rate of implantation decreased and the rate of preimplantation loss showed an(More)
In order to examine the toxicity profile of glycine, an authorized food additive, a solution of glycine in water for injection was administered orally (via gavage) to male SD rats (Crl:CD(SD)) once daily for 4 weeks at doses of 500, 1000 and 2000 mg/kg/day in a volume of 10 mL/kg. Control animals received vehicle only. No animals died, and no(More)
To examine 4-week toxicity of l-methionine (methionine), 5-week-old Fisher strain male rats were fed on diets containing 0, 0.1, 0.3, 0.9, 2.7 (w/w) of added methionine. Although no deaths were recorded, the highest dose of methionine (2.7% [w/w] of diet) reduced food intake and significantly suppressed growth rate. Growth suppression was characterized by(More)
