Norepinephrine turnover in pineal gland and superior cervical ganglia. Changes after gonadotrophin administration to castrated rats

The effects of FSH and LH on norepinephrine (NE) turnover in pineal gland and superior cervical ganglia of castrated female rats were examined by measuring the decline of [3H]NE concentration in the organ 30-120 min after a single i.v. injection of the labeled amine. Both FSH and LH treatment signif...
