A pituitary adenoma with suprasellar extension that had caused hyperthyroidism due to secretion of excess thyrotropin (TSH), as well as mild hyperprolactinemia, was studied with differential staining, immunocytochemistry and electron microscopy. Most cells of the tumor strained lightly with aldehyde thionin, which demonstrates the granules of normal(More)
The purpose of this study was to determine if there were ultrastructural and immunocytochemical changes in intermediate lobe cells following stress. We found marked cytological changes in intermediate lobe cells after 30 min of stress with a buzzer and stroboscopic light (neurogenic). Following such treatment, the cytoplasm was filled with pale graules or(More)
