For 8 weeks 10 male weanling Sprague-Dawley rats were fed a semisynthetic diet containing by weight either 20% corn oil or rapeseed oils containing different amounts of erucic acid (Brassica napus var. Zephyr, 0.6%; B. napus var. Oro, 1.8%; B. campestris var. Span, 4.8%; or B. campestris var. Echo
Five groups of male weanling rats were provided purified diets containing 15% by weight of either fresh or laboratory-heated corn oil (FCO, HCO) or fresh, laboratory-heated, or commercial pressure deep-fry peanut oil (FPO, HPO, PPO). Total weight gain, feed consumption, and feed efficiency were
Arotinoids, which are analogs of retinoic acid (RA) and retinol (RO) with the carbon skeleton in a rigid conformation, have more favorable therapeutic indices relative to all-trans-RA and all-trans-RO. The purpose of this investigation was to obtain preliminary in vivo toxicity data on SMR-2(analog
The potential maternal, embryotoxic, and teratogenic parameters of 2,4-dichlorophenol (2,4-DCP) were evaluated in Fischer 344 rats following oral administration in corn oil on Days 6 through 15 of gestation. Dose levels were 0, 200, 375, and 750 mg/kg/day. Females were sacrificed on Gestation Day 20
The fragrance ingredient 4-tert-butylcyclohexyl acetate (4-tBCHA) was evaluated for potential developmental toxicity in pregnant rats at oral dosages of 0, 40, 160, or 640 mg/kg per d in corn oil on gestational days 7 to 20. Increased salivation was observed at 160 and 640 mg/kg per d. The 640 mg/kg
Treatment of a light fraction of petroleum treated by metallic catalysis results in a liquid mixture of low molecular weight compounds named LarimshTM (LR). Acute and chronic topical treatment of mice with LR (85 days with 0.1 to 1 mL/animal) indicated no signs of toxicity other than a non
