Two 3 x 3 factorial experiments were conducted to examine the effects of dietary protein (8, 16, and 32% of energy from casein) and dietary fat (12, 24, and 48% of energy from corn oil) on the initiation and promotion of azoxymethane-induced carcinogenesis in rats. For the initiation study, 33 weanling male Sprague-Dawley rats were randomized to each of(More)
SUMMARY Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by accumulation of amorphous acellular phospholipid material in the lungs. Whole lung lavage is the standard therapy which gives dramatic clinical improvement and offers a long term survival to these patients. A 43-year-old man suffering from PAP presented to casualty with NYHA(More)
A factorial experiment was conducted to examine the effects of dietary protein (8, 16, 32% of energy from casein) and dietary fat (12, 24, 48% of energy from corn oil) on the initiation of 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast carcinogenesis in rats. Forty weanling female Sprague-Dawley rats were assigned to each of nine diets fed ad libitum.(More)
The relationships between dietary fat concentration (10 or 40% of energy), fat source (corn oil or beef tallow) and estrogen (control, ovariectomy or ovariectomy with estrogen replacement) to 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast carcinogenesis and survival in rats were studied in a 2 x 2 x 3 factorial experiment. Female Sprague-Dawley rats(More)
1,2-Dimethylhydrazine-HCl (DMH-2HCl) is derived from the natural toxin cycasin, and is extensively used to induce cancers in experiments with rodents. We examined the toxicity of DMH-2HCl, incorporated into purified diets varying in protein, to determine concentrations compatible with long-term survival in B6C3H1 mice. Initial studies showed single-dose(More)
