Autor: J R Millette, W F Mueller, J M Cohen, B J Kelman, L V Uppala, L J Swenson

Publikováno v: Applied occupational and environmental hygiene. 14(3)

We conducted an evaluation of shredded paper insulation to identify potentially toxic components. The study was to provide a preliminary characterization of a few samples of insulation currently in use. The following samples were analyzed: previously

Sprague--Dawley rats were given access to water containing control, 10, 25 ppM Cd beginning on day 0 of gestation. On day 21 of gestation, fetal and maternal tissues were collected from dams which had been dosed 24 hr previously with 16 ..mu..Ci of /

Fetal to maternal cadmium movements across the perfused hemochorial placenta of the guinea pig

Autor: B. J. Kelman, B.K. Walter

Publikováno v: Toxicology and Applied Pharmacology. 52:400-406

Guinea pig placentas (59 to 61 days gestation) were perfused from the fetal side in situ. Radiolabeled CdCl2 was added to the perfusing fluid, and the dam was injected with tracer quantities of tritiated water. Cadmium clearance from fetal to materna

Absorption of Mercury from Ligated Segments of the Rat Gastrointestinal Tract

Autor: B. K. Walter, G. E. Jarboe, L. B. Sasser, B. J. Kelman

Publikováno v: Experimental Biology and Medicine. 157:57-60

SummaryThe ligated segment technique was used to compare the gastrointestinal absorption of methylmercury and mercury chloride in the rat. Methylmercury was more readily absorbed (15-35 times greater, depending on the absorption site) than inorganic

Passage of Cadmium Across the Perfused Guinea Pig Placenta

Autor: B. K. Walter, B. J. Kelman

Publikováno v: Experimental Biology and Medicine. 156:68-71

SummaryBy perfusing the fetal circulation of placentas (61- to 63-days gestation) in situ, we were able to separate fetal uptake from placental transport of cadmium in the guinea pig. Our data indicate that cadmium crosses the placenta from the mater

Effects of Ultrasound on Placental Function

Autor: R. A. Pappas, M. R. Sikov, B. J. Kelman

Publikováno v: IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control. 33:218-224

Reports indicate that exposure to ultrasound can produce adverse effects on blood Row and uterine tissue under appropriate con- ditions. Thus it is important to directly investigate the effects of ultra- sound on placental function. To accomplish thi

Cadmium-binding in the pregnant and fetal rat

Autor: B. J. Kelman, L. B. Sasser, B. K. Walter, Jocelyn A. Ozga

Publikováno v: Toxicology Letters. 4:135-141

A cadmium-binding moiety with properties in common with adult cadmiumthionein was identified in the livers of fetal rats at day 18 of gestation. Pregnant rats (approx. 200 g) were subcutaneously injected with 50 μg of radiolabeled cadmium in the for

Effect of red-cell-bound mercury on measurements of tissue mercury distribution

Autor: G. E. Jarboe, L. B. Sasser, B. J. Kelman

Publikováno v: Bulletin of Environmental Contamination and Toxicology. 16:612-617

Blood is the transport vehicle of methylmereury (MeHg) in the body (GIBLIN and MASSARO, 1974; NORDBERG and SKERFVING, 1972; PASSOW, 1970; WHITE and ROTHSTE!N, 1973), with almost complete binding to the hemoglobin molecule (GARCIA et al., 1974; ROTHST
