Radioactivity in pituitaries and cerebrums of neonatal rats following [3H]-estradiol administration.
The uptake of radioactivity by the pituitary, cerebrum and muscle of female and male neonatal and prepuberal rats 1 hour after administration of [3H]-estradiol was measured by liquid scintillation. Tissues were homogenized and aqueous, lipid, and protein-nucleoprotein fractions were separated for quantification of radioactivity. No significant sex differences in the radioactivity associated with the pituitary fractions were noted at any of the ages studied.
