Two experiments were conducted to examine the relative precision of bone densitometry and bone ash methodologies as response criteria in measurement of bioavailability of phosphorus from various supplements for turkeys. Multivariate analyses of variance were used to analyze data collected. Coefficients of correlation and variation and F ratios were used for(More)
A chronic hyperalgesic condition was induced in mice by the injection of Freund's complete adjuvant (FCA) into the lower lumbar region or directly into the hind footpads. Although little or no visible inflammation was observed after a single intradermal injection of FCA into the lower lumbar area of rats or mice, significant alterations in nociceptive(More)
Tibial dyschondroplasia was induced in female broiler chicks by the incorporation of 2% Fusarium roseum "Alaska" culture into their starter ration. Chicks were placed on this diet at one day of age and maintained until they were killed at four days or one week. Proximal tibial physes were grossly thickened into cone-shaped masses of cartilage by one week of(More)
Tibial dyschondroplasia was induced in broiler chickens by oral administration of fusarochromanone, the toxic component of Fusarium equiseti. In two experiments, the activity of acid phosphatase in chondroclasts was assessed histochemically. Chicks were examined at 7, 14, 21, and 28 days of treatment in Expt. 1 and at 2, 4, and 6 days of treatment in Expt.(More)
Cis-diamminedichloroplatinum (II) (cisplatin) is a frequently used cancer chemotherapeutic agent. Nephrotoxicity is a serious dose-limiting side effect. Many approaches have been studied for protective action against cisplatin-induced nephrotoxicity, but with the exception of diuretics and hydration none are in widespread use. We have used a modified(More)
A trial was conducted to determine the effects of dietary level of selenium on the pathogenesis of Fusarium-induced tibial dyschondroplasia (FITD) in broiler chicks, and to assess the applicability of FITD as an animal model of Kashin-Beck disease of humans. Day-old female broilers were fed diets that were deficient in selenium (0.02 ppm Se), adequate in(More)
We have previously shown that macrophages from chickens infected with avian reovirus are primed to produce nitric oxide (NO) in response to T cell cytokines and bacterial lipopolysaccharide (LPS). We now show that NO exerts potent antireovirus effects. Reovirus replication was substantially reduced in a chicken macrophage cell line, HD11, induced to make NO(More)
Large white male turkey poults were fed diets with different levels of vitamins A and D to study the interaction of these vitamins with regard to skeletal development. Poults fed a basal diet deficient in both vitamins A and D developed severe lameness, growth depression, mortality and lesions consistent with rickets. Birds fed a diet containing the(More)
