Morphometric study of the effect of hypervitaminosis A on the rat parotid gland.
Hypervitaminosis A induces the following changes in the rat parotid gland: smaller size acini with lower cells and a smaller number of cytoplasmic granules, decreased acidophilia, and smaller nuclei. The striated ducts show smaller, disorganized cells with smaller nuclei, as well as increased secretion in their lumina. These data were confirmed by morphometric techniques.
