Placental transfer and pharmacokinetics of a single dermal dose of [14C]methyl parathion in rats.
The pharmacokinetics and placental transfer of a single dermal 10.0 mg (10microCi)/kg dose of uniformly phenyl-labeled [14C] methyl parathion (0,0-dimethyl 0-4-nitrophenyl phosphorothioate) were investigated in pregnant Sprague-Dawley rats at 14-18 days of gestation. Three rats were killed at each time interval: 1, 2, 4, 12, 24, 48, 72, and 96 h after dosing. Radioactivity disappeared biexponen...
متن کاملPlacental transfer and tissue distribution of 14C-styrene: an autoradiographic study in mice.
The distribution of 14C-styrene was studied in the pregnant mouse using a whole body low temperature autoradiographic technique. In unsectioned tissues studied by liquid scintillation the concentrations of styrene and its metabolites in maternal and fetal blood and organs and in the placenta and amniotic fluid were determined. The organs which had higher concentrations of volatile styrene were ...
متن کاملMetabolic fate of 14C-labelled nicotinamide and adenine in germinating propagules of the mangrove Bruguiera gymnorrhiza.
We studied the metabolic fate of [carbonyl-14C]nicotinamide and [8-(14)C]adenine in segments taken from young and developing leaves, stem, hypocotyls, and roots of a shoot-root type emerging propagule of the mangrove plant Bruguiera gymnorrhiza. Thin-layer chromatography was used together with a bioimaging analyser system. During 4 h of incubation, incorporation of radioactivity from [carbonyl-...
متن کاملPlacental Transfer of Sulfamethazine in Mice and Rats
SimunekJ., A. B. Siddique, E. Hegerova: Placental Transfer of Suljamethazine in Mice and Rats. Acta Vet. Brno, 47,1978: 145-151. Placental transfer of sulfamethazine in mice was investigated in the second half of their pregnancy. The transfer was not free but only a part of the drug administered to mothers was found to pass from the maternal circulation to the fetus. Placental transfer of sulfa...
متن کاملMetabolic fate of intravenously administered N-acetylneuraminic acid-6-14C in newborn piglets.
BACKGROUND Sialic acid (N-acetylneuraminic acid), a component of gangliosides and sialylglycoproteins, may be a conditional nutrient in early life because endogenous synthesis is limited. The aim of this study was to investigate the metabolic fate of intravenously administrated N-acetylneuraminic acid-6-14C (sialic acid) in piglets. METHOD Three-day-old male domestic piglets (Sus scrofa) were...
