A technique was developed, which made it possible to study thein vitro release of3H-acetylcholine (3H-ACh) from human post mortem brain tissue, collected with short post-mortem delay (2,5–22 hours), both from controls and patients with Alzheimer's disease (AD/SDAT). The tritium (3H) release was investigated during potassium stimulation, and AD/SDAT cortical slices were found to release a decreased amount of3H compared to control brain slices. Physostigmine, 10−5 and 10−4 M, has no significant effect on the release of3H from control slices, while physostigmine 10−4 M increased the evoked release from AD/SDAT brain slices over threefold, nearly to the control level.
