The distribution of 2,21,3,4,41,61, and 2,31, 4,41,51,6- hexachlorobiphenyl in mice studied by whole-body autoradiography. 1975

I Brandt

The distribution of 14C-labelled hexachlorobiphenyl in male and pregnant female mice was studied by whole-body autoradiography and liquid scintillation counting. Shortly after an intravenous injection there was a strong uptake of polychlorinated biphenyl (PCB) in the corpora lutea, the adrenal cortex and the liver and radioactivity was retained fro a long time in these tissues. Even in the fetal adrenal cortex a considerable accumulation occurred. High activity was also present in the brown fat, the lung, the the myocardium, the gastric mucosa, the pituitary and the bone marrow. Radioactivity penetrated slowly to the brain and fetal tissues but the concentration remained consistently low. In the adipose tissues there was a gradual increase in radioactivity and the autoradiograms from the longer survival times were dominated by these sites. There was a continuous biliary excretion of labelled material to the small intestine; this occurred in the fetuses as well.

D011078	Polychlorinated Biphenyls	Industrial products consisting of a mixture of chlorinated biphenyl congeners and isomers. These compounds are highly lipophilic and tend to accumulate in fat stores of animals. Many of these compounds are considered toxic and potential environmental pollutants.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D005333	Fetus	The unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.
