Morphological findings in granular reticulum of arcuate nucleus neurons after clomiphene citrate administration.
The action of high doses of clomiphene citrate on the rough endoplasmic reticulum of the hypothalamic arcuate neurons of male cat has been studied. Clomiphene (250 mg/kg) produces an accumulation of typical paracrystalline material in the rough endoplasmic reticulum. After the administration of a protein-synthesis inhibitor no such material was observed in clomiphene-treated cats. The possibility exists that the specific ultrastructural changes seen indicate an increased protein synthesis in hypothalamic arcuate neurons.
