The pituitary gland and infundibulum can be involved in a variety of medical conditions, including infiltrative diseases, fungal infections, tuberculosis, and primary and metastatic tumors. Metastases to the pituitary gland are absolutely rare, and they are generally secondary to pulmonary carcinoma in men and breast carcinoma in women. Pituitary metastases more commonly affect the posterior lo...

RFamides are a relatively recently-discovered class of peptides characterised by an arginine-phenylalanineamide at their C terminus. In mammals, all of the five known RFamide families (neuropeptide FFs, prolactin-releasing peptides, RFamide-related peptides, kisspeptins and pyroglutamylated RFs) were originally discovered as neuropeptides influencing central nervous system functions such as rep...

The cytokine interleukin-1 (IL-1) has a number of biologic activities, including pronounced effects on the nervous and neuroendocrine systems. In this study, in situ histochemical techniques were used to investigate the distribution of cells expressing type I IL-1 receptor mRNA in the CNS, pituitary, and adrenal gland of the mouse. Hybridization of 35S-labeled antisense cRNA probes derived from...

Two isozymes of carbonic anhydrase (EC 4.2.1.1.) were compared in the anterior pituitary gland of non-tumor-bearing rats and in the hormone-secreting pituitary tumors. In contrast to the pituitary gland, which contained 60 to 70% of the total carbonic anhydrase in the particulate subcellular fraction, three hormone-secreting pituitary tumors were devoid of the particulate (Triton X-100-solubili...

A solitary intrasellar plasmacytoma with marked pituitary fossa destruction and yet near normal pituitary gland function is described. We suggest that a minimal disturbance of endocrine function together with a radiologically abnormal pituitary fossa indicates that the primary lesion may lie outside the pituitary fossa.

Pituitary apoplexy is a rare event in which the pituitary gland undergoes infarction or haemorrhage, most commonly in the setting of an underlying tumour. We report on apoplexy of an undiagnosed pituitary adenoma precipitated both by physiological enlargement of the pituitary in pregnancy and prophylactic anticoagulation from a history of deep vein thrombosis. The haemorrhage was managed conser...

Hormones are hormones secreted by the thyroid gland and their primary function is to regulate speed of metabolism in many tissues. The releases its into bloodstream response a regulating hormone released pituitary called thyroid-stimulating hormone. It only organ body that has ability synthesize iodine large quantities for use synthesis hormones. consists two lobes, joined together isthmus, loc...

By the end of this section, you will be able to: • Explain the interrelationships of the anatomy and functions of the hypothalamus and the posterior and anterior lobes of the pituitary gland • Identify the two hormones released from the posterior pituitary, their target cells, and their principal actions • Identify the six hormones produced by the anterior lobe of the pituitary gland, their tar...

This study investigates the influence of age and sex on the volumes of the pituitary fossa and gland in 91 males and 108 females from Croatia who underwent magnetic resonance imaging of the endocranium for complaints not related to the pituitary gland. Isometric 3DT1 MPRAGE and 3DT1 MPR sequences were obtained on 1.5. Tesla and analysed on ISSA software. The volumes were obtained from the sum o...
