Prolactin secreting pituitary carcinoma.
A man with a prolactin secreting pituitary carcinoma was treated by surgery and radiotherapy. Persistent hyperprolactinaemia partially responded to oral bromocriptine for four years. Serum prolactin then rose considerably with rapid, invasive tumour recurrence. Cytotoxic chemotherapy halted tumour progression for twelve months before fatal spread throughout the brain. Failure to normalise serum...
متن کاملProlactin Secreting Pituitary Adenomas
Correspondence to: Ioana Muntean, e-mail: [email protected] ABSTRACT. Hyperprolactinemia has different etiologic forms, among them, the prolactin-secreting pituitary tumors represent an important entity. In our study, were analyzed the clinical aspects, diagnostic procedures and therapeutical approach of 31 cases of prolactinomas (F/M ratio = 27/4) hospitalized in the Clinic of Endocrinol...
متن کاملStudies on the prolactin-like substance in human placenta. IV.
In the previous papers (Ito and Higashi, 1961; Higashi, 1961), it was reported that a protein which stimulates the increase of the number and size of the fatty granules in the crop milk of pigeons was obtained from human placenta by the fractional precipitation with ammonium sulfate. The present communication describes the procedure of purification of this biologically active substance and some...
متن کاملPectic Acid Effects on Prolactin Secretion in GH3/B6 Rat Pituitary Cell Line
Background: Pectic acid extracted from plants increases the secretion of prolactin (PRL) when injected intravenously into ewes or fed to rats. Fragments of ewe hypophysis and lactating rabbit mammary gland incubated in vitro in the presence of pectic acid secreted more PRL and caseins compared to the controls. However, it is not known whether pectic acid directly stimulates PRL secretion in pi...
متن کاملProlactin receptor antagonism in mouse anterior pituitary: effects on cell turnover and prolactin receptor expression.
Since anterior pituitary expresses prolactin receptors, prolactin secreted by lactotropes could exert autocrine or paracrine actions on anterior pituitary cells. In fact, it has been observed that prolactin inhibits its own expression by lactotropes. Our hypothesis is that prolactin participates in the control of anterior pituitary cell turnover. In the present study, we explored the action of ...
