[Human pituitary growth hormone cell adenomas, ultrastructural and immunoelectron microscopical study].

Abstract

24 cases of growth hormone(GH)-producing pituitary adenomas were studied with electron microscopy and immunoelectron microscopy by protein A-gold complex, 6 cases were identified as densely granulated GH adenoma and 15 cases as sparsely granulated GH adenoma, among which 4 cases were proved by immunoelectron microscopy to be containing granules with prolactin(PRL) activity simultaneously. Intracytoplasmic fibrous bodies were often seen in the sparsely granulated cells anyhow, not all those cells with fibrous bodies possess the secretory granules with GH activity, and fibrous bodies were also detected in some PRL cells of certain mixed type adenoma. This suggests that fibrous bodies might not be the specific morphological feature of pituitary growth hormone cell adenomas.
