Fetal and maternal levels of corticosterone and ACTH after pharmacological adrenalectomy
Abstract
A paradigm of pharmacological adrenalectomy of pregnant rats and fetuses in utero is described. A regimen of twice daily metyrapone injections (10 mg/100 gm body weight), results in marked depression of serum corticosterone in pregnant and in fetal rats without surgical trauma and stress. The technique should be useful in a wide variety of studies involving the developing brain-adrenal axis.
