Objectives (1) To describe the ultrastructural features of corneal sequestra in cats; and (2) to enhance our understanding regarding the pathogenesis of feline corneal sequestration. Methods Nine corneal sequestra were harvested via keratectomy from globes of nine cats. The sequestra were routinely ...

The pH stability and acute oral toxicity of dimethoxymethane (DMM) in rats were studied, In in vitro studies, DMM was found to be stable in artificial gastric juice at pH 2.5 and above but readily hydrolyzed at pH2 and below, with 1 mole of DMM producing approximately 1 mole of formaldehyde and 2 mo...

Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that bioaccumulate in the food chain and thus pose a health risk to humans and other animals. In this study, PCB 118 was added to the diets of Sprague Dawley rats for 13 weeks in concentrations of 2, 20, 200, 2000 p.p.b. to t...

Hepatocyte cytoplasmic alterations were morphometrically determined in male and female Sprague-Dawley rats fed PCB congener 126 (3,3',4,4',5-pentachlorobiphenyl) in concentrations of 0.1, 1.0, 10, 100 ppb or corn oil in diets for 13 weeks. A dose-dependent increase (P < 0.05) in the volume fracti...

Polyhalogenated aromatic compounds such as polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins continue to be environmental contaminants because of their bioaccumulation in the food chain and resistance to biodegradation. This study was undertaken to determine if WHO-IPCS PCB cong...

Although reproductive consequences of high circulating blood lead levels (greater than or equal to 60 mu g/dL) have been reported, potential adverse effects of chronic lead exposure in males that result in low to moderate blood lead levels (10-25 and 26-60 mu g/dL, respectively) are unknown. Effects...

BACKGROUND: Taste buds on the pig tongue have been neither studied in detail nor quantified. We have counted the numbers of fungiform and vallate papillae, estimated their taste bud densities, and computed numbers of taste buds per volume of papilla on porcine tongue. Pig was chosen for this work be...

PCB 105 (2,3,3',4,4'-pentachlorobiphenyl) congener was fed to weanling Sprague-Dawley rats in a diet combined with 4% corn oil. The animals were distributed randomly into 10 groups, each of which contained 10 males and 10 females, and rats in 8 groups received diets containing PCB at concentrations ...

2,4,4'-Trichlorobiphenyl or PCB congener 28 was given to Sprague-Dawley weanling rats and the experimental diets were prepared by mixing the congener in 4% corn oil. The congener was administered to animals placed in four groups, each comprising 10 males or females. The diets contained 0.05, 0.5, 5,...

Effect of Tower rapeseed oil (RO) containing lower (0.4%) erucic acid on the piglet liver was studied by electron microscopy. The animals were placed in two groups of four and were fed the diets for eight weeks. Animals in the treated group were given a basal diet comprising corn-soybean plus Tower ...

3,3',4,4',5-pentachlorobiphenyl (PCB) or congener n. 126 and 2,3',4,4',5-pentachlorobiphenyl or congener n. 118 were given independently to male and female Sprague-Dawley weanling rats. Experimental diets were prepared by dissolving the congeners in 4% corn oil. The congeners were administered as fo...

Morphological effects on the liver of Sprague-Dawley rats administered orally 2,2',4,4',5,5'-hexachlorobiphenyl (PCB), congener #153, were analyzed. Treatment diets were prepared by dissolving the congener in 4% corn oil. Ten animals of either sex in each group were placed on the respective diets th...

Ultrastructural effects of 3,3'4,4'-tetrachlorobiphenyl (PCB) congener #77 on the liver were evaluated following its feeding to Sprague-Dawley weanling rats. Treatment diets were prepared by dissolving the congener in 4% corn oil. Ten animals, either male or female, in each group were placed on the ...

The purpose of this study was to establish the effects of lead on the non-human primate testis. Sixteen cynomolgus monkeys maintained in environmentally controlled conditions were administered 1500 mug lead acetate/kg bw/day in gelatin capsules. Monkeys were randomly assigned to the following groups...

Hexachlorobenzene is a persistent chlorinated organic chemical that has been detected in many tissues from a variety of species including human ovary and human ovarian follicular fluid. When administered in high dosage to nonhuman primates, hexachlorobenzene causes destruction of ovarian primordial ...
