    • ‘Erdheim-Chester disease may involve the pituitary, causing diabetes insipidus and other endocrine abnormalities.’
    • ‘This hormone stimulates the pituitary, another endocrine gland near the brain, to secrete adrenocorticotropic hormone.’
    • ‘The majority of cases are caused by a somatotroph adenoma of the anterior pituitary, and most are confined to the sella.’
    • ‘Anterior pituitaries were harvested at slaughter, and the reverse plaque assay was used to examine the composition of the acidophils.’
    • ‘LH is secreted by the pituitary glands in response to negative feedback from Testosterone.’
    • ‘In addition, the pituitary secretes hormones that signal the ovaries and testes to make sex hormones.’
    • ‘External beam radiation was delivered to the pituitary / suprasellar region.’
    • ‘Isolated pituitaries were enriched for lactotrophs as described.’
    • ‘Consequently, the pituitary receptors would be preserved, and the pituitary would erroneously sense that the thyroid status in the periphery is normal.’
    • ‘Tadpole pituitaries secrete thyroid-stimulating hormone in response to CRH.’

    • ‘Horses with pituitary tumors have a tendency to get secondary infections.’
    • ‘Adrenal and pituitary integrity must be established.’
    • ‘Pituitary adenomas exhibited intense diffuse cytoplasmic reactivity.’
    • ‘The cytologic and architectural features of these tumors are reminiscent of those of the normal posterior pituitary lobe.’
