title: Effects of hypothyroidism on the ultrastructure of rat pancreatic acinar cells: a stereological analysis.
abstract: The morphological and stereological characteristics of the exocrine pancreas subcellular organelles from healthy and thyroidectomized rats have been studied. The acinar tissue from hypothyroid rats showed an interstitial edema and evidence of degenerative processes. Stereological parameters of zymogen granules were significantly reduced in thyroidectomized rats. The hypothyroidism induced degenerative changes in the pancreatic acinar cells as well as a decrease in the number and size of the zymogen granules. These modifications probably cause functional alterations.
