biphenyl/edema

OBJECTIVE To study the effects of polychlorinated biphenyl (PCB) on the phenotype of the testis tissue and the testis tissue and the expression c-fos, c-Myc and beta-catenin in the rat testis. METHODS Forty-five Wistar male rats were divided into a control and three perimental groups, the former fed

We determined that in ovo exposure to polychlorinated biphenyls (PCBs) alters growth of first-generation nestlings during and one year after parental exposure. Captive American kestrels (Falco sparverius) laid eggs with environmentally relevant total PCB levels (34.1 microg/g whole-egg wet wt) when

The toxicities of the coplanar polychlorinated biphenyls 3,3',4,4'-tetrachlorobiphenyl (TCB), 3,3',4,4',5-pentachlorobiphenyl (PeCB) and 3,3',4,4',5,5'-hexachlorobiphenyl (HCB) were compared in a 72-h study on chick embryos. The substances were injected into the air sacs of hens' eggs preincubated

Diseases due to the degeneration of the liver and various other internal organs were the major cause of the exceedingly high chick mortality in lesser black-backed gulls (Larus fuscus fuscus) in the central Gulf of Finland, Baltic Sea, during 1991-1993. The same symptoms were found in chicks of

This study found abnormalities in multiple reproductive stages in captive American kestrels (Falco sparverius) when exposed to polychlorinated biphenyls (PCBs) through dietary and in ovo exposure. American kestrels laid eggs with environmentally relevant total PCB levels (34.1 micrograms/g whole egg

A spontaneous, progressive disease occurred in a large domestic breeding colony of rhesus monkeys (Macaca mulatta). The disease was characterized by slow but continuous weight loss, alopecia, acne, facial edema, diarrhea and trauma from other monkeys. Breeding efficiency was impaired with a high

Day old cockerels were given a ration containing 500 ppm of polychlorinated biphenyls (PCB) as Aroclor 1254. Mortality was recorded and various tissues analyzed for PCB levels. Tissue concentrations of PCB increased in direct relation with the time of the experiment and with the survival period of

A series of 1,3,4-oxadiazole/thiadiazole and 1,2,4-triazole derivatives of biphenyl-4-yloxy acetic acid were synthesized in order to obtain new compounds with potential anti-inflammatory activity, analgesic activity and lower ulcerogenic potential. All compounds were evaluated for their

Toxicosis was induced in pregnant Holstein-Friesian heifers by giving polybrominated biphenyls a in gelatin capsules at the rate of 25 g/day. Initially, this dosage was approximately 67 mg/kg of body weight. Clinical signs were anorexia, excessive lacrimation and salivation, diarrhea, emaciation,

Several populations of fishes inhabiting contaminated Atlantic Coast estuaries exhibit resistance to early life-stage (ELS) toxicities induced by halogenated aromatic hydrocarbons such as coplanar polychlorinated biphenyls (PCBs). These toxicities include mortality, circulatory failure, edema, and

Polychlorinated biphenyls are a widespread aquatic contaminant. In this article, specific polychlorinated biphenyl congeners were examined for embryo and early life-stage toxicity in zebrafish (Danio rerio). A set of three polychlorinated biphenyl congeners (non-ortho polychlorinated biphenyl 126,

In order to investigate immunological abnormalities induced by polychlorinated biphenyls and polychlorinated dibenzofurans, we have performed bronchoalveolar lavage in the rats given polychlorinated biphenyls and polychlorinated dibenzofurans. We have administrated 5.0 mg of polychlorinated

Polybrominated biphenyl (PBB), structurally similar to polychlorinated biphenyl (PCB), affects feed intake, egg production, and hatchability of fertile eggs in chickens and quail. Subcutaneous edema of the neck and shoulder are common abnormalities of hatched chicks from PBB-fed dams. No
