Abstract
Summary
A sensitive and specific radio-immunoassay for hypothalamic LH-RH has been described. Within 7 days after castration there is a significant decline in hypothalamic content of LH-RH in adult male rats. Total starvation for 7 days does not affect hypothalamic content of LH-RH in either intact or castrated rats.
The authors thank the Hormone Distribution Officer, NIAMDD, for reagents for the radioimmuno-assay of rat LH and rat FSH. They also thank Mrs. E. Morris for secretarial assistance.
