The circadian clock located in the suprachiasmatic nuclei (SCN) was characterized in the fetal rat by using 14C-labeled deoxyglucose to monitor glucose utilization (metabolic activity) of the nuclei. A clear day-night oscillation of metabolic activity was detectable in the fetal SCN from the 19th through the 21st days of gestation; the nuclei were metabolically active during the subjective day ...

Pregnant Sprague-Dawley rats received 50, 250, and 500 mg/kg/day diisononyl phthalate (DiNP) from GD 12 to 19 via corn oil gavage to study the dose response for effects on fetal male rat sexual development as well as metabolite disposition in the dam and fetus. Monoisononyl phthalate (MiNP), mono(carboxy-isooctyl) phthalate (MCiOP), mono(hydroxyl-isononyl) phthalate (MHiNP), mono(oxo-isononyl) ...

conclusion reference ranges for umbilical cord csa have been generated. the csa of the umbilical cord and other components of it increase as a function of gestational age. these measurements correlate with fetal size. results the values of the csa of the umbilical cord, umbilical vein and wharton’s jelly (wj) increase consistently until 30 weeks of gestation, after which they reach a plateau. t...

most women want to know about possible consequences radiology, radioisotope or even television terminal. because knowing about them, prevent from fear. fetus is inevitably placed to some types of radiation. environmental radiation occurs from atmosphere, soil and buildings. total radiation above, ingested and possibly inhaled radioisotopes probably is seventy five-thousandth to one-tenth of ram...

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...
