On the ultrastructure and immunocytology of arcuate neurons with perpetuated feedback effect.

ABSTRACT

Electron microscopy reveals rough endoplasmic reticulum and other cytoplasmic organelles in the intranuclear spheroids of human arcuate neurons with feedback phenomenon. After peroxidase-antiperoxidase technique was applied some of these arcuate nerve cells demonstrated luteinizing hormone releasing hormone immunoreactivity.
