Abstract
Changes of glycolipids in the brain after formalin fixation were examined. Quantity of lipids in the brain decreased rapidly after formalin fixation. Glycolipids decreased to 50% 24 hours after fixation, and to 10% after 4 months after fixation. Fatty acid composition of glycolipids showed a change characterized by both a diminution of long-chain fatty acids (C: 16-20) and an increase of long-chain fatty acid (C: 23-27) 4months after fixation, and its change was more markedly noted in normal fatty acids than hydroxy fatty acids.
