SOME ASPECTS OF THE METABOLISM OF SULFATE-S35 AND CALCIUM-45 IN THE METAPHYSES OF IMMATURE RATS

Abstract

Weanling rats were given 2 mg. of 17-ß-estradiol benzoate at weekly intervals for 4 weeks. Twenty-four hours after each intraperitoneal injection of the estrogen 100 µc. of S³⁵-sulfate or 11 µc. of Ca⁴⁵ was similarly injected. The animals were sacrificed 24 hours after the last dose of isotopes.
