thirty-four ( 77 % ) of the meningiomas contained high titers of specific high-affinity cytosol [ 3h ] promegestone ( r 5020 ) binding sites ( mean 2,902 fmol/g tumor ; range 0-9,598 fmol/g tumor ) whereas only miniscule amounts of a nonspecific cytoplasmic [ 3h ] estradiol binding component ( mean 48 fmol/g tumor ; range 0-201 fmol/g tumor ) were detectable .
