Abstract:

Lipogenic pigmentation is described in thyroid follicular, parathyroid, and pineal cells, as well as in adrenocortical macrophages. Piracetam activated pituitary prolactin cells and increased paracrystals in thyroid follicular cells; smooth endoplasmic reticulum was increased and glycogen content decreased in numerous hepatocytes randomly distributed over the lobule.
