title: Electron microscopic studies on the pars intermedia of the rat under stress.
abstract: Using electron microscopy, we have studied the pars intermedia (PI) of the pituitary gland of Wistar rat under psychogenic stress, finding a considerable increase in dark cells. The cells of the PI present striking vacuoles in all their cytoplasms, increasing up to a phase of total cellular disintegration. We have also observed a cell type, not found in the animal control group, of regular size and electrondense matrix of medium contrast.
