Abstract
Summary
The incorporation and fate of estradiol-17β-6,7-H3 was studied in the female rabbit. The Fallopian tube of the rabbit showed an affinity for estradiol-17β at the same level as uterine tissue. The major portion of radioactive steroids present in the Fallopian tube, uterus and skeletal muscle was in the ether-soluble fraction, whereas in plasma significant amounts of activity were present in the aqueous layer. Estradiol-17β was the only radioactive estrogen found in the tubal and uterine tissues. Radioactivity was identified as estrone and estradiol-17β in the skeletal muscle, and as estrone, estradiol-17β and estriol in the plasma.
