The Effect of Aspirin on Gomori-positive Glia in Mouse Brain*

Aspirin (acetylsalicylic acid, ASA) treatment resulted in a significant decrease in the amount of the sulfur-rich Gomori-positive material present in the cytoplasm of periventricular glia. It also caused the accumulation of the Gomori-positive neurosecretory material in the supraoptic and paraventricular nuclei and, most pronounced, in the neurosecretory axons of the paraventricularand supraoptic-neurophypophysial tract.
