    Notizen: Summary 1. We have localized and quantified neuropeptide Y (NPY) binding sites in the rat pituitary gland after incubation of tissue sections in the presence of125I-Bolton-Hunter NPY followed by autoradiography, computerized microden-sitometry, and comparison to125I-standards. 2. In the rat, NPY binding sites are localized exclusively to the part of the posterior pituitary lobe closer to the pituitary stalk. No NPY binding sites could be found in the intermediate or the anterior pituitary lobes. 3. Our results suggest a role for NPY in the regulation of pituitary function and, in particular, that of the neural lobe.

    Estradiol increases dopamine turnover in intermediate and posterior pituitary lobes of ovariectomized rats (1984)

    Notizen: Summary 1. Dopamine levels were specifically increased in the intermediate lobe of the pituitary gland of ovariectomized rats following acute 17-β-estradiol administration. 2. Estradiol treatment increased the dopamine turnover rate 10-fold in the intermediate lobe and 2-fold in the posterior lobe of ovariectomized rats. 3. In contrast, estrogen treatment had no effect on the endogenous levels or the turnover rate of norepinephrine in these tissues. 4. Our results suggest that estrogens can selectively modulate dopamine metabolism in the posterior and intermediate lobes of the rat pituitary gland.
