Increased effectiveness of tacrine by deprenyl co-treatment in rats
Bibliographic record
Abstract
The acetylcholinesterase inhibitor tacrine and the monoamine oxidase inhibitor deprenyl are considered useful pharmacotherapies for Alzheimer's disease (AD). We assessed whether co-administration of these two compounds increases their effectiveness against two measures of cholinergic-monoaminergic hypofunction in rats, cortical EEG slowing and impaired spatial performance. EEG slowing induced by cholinergic-monoaminergic blockade was reversed by both deprenyl (10 - 50 mg/kg) and tacrine (1 - 20 mg/kg), but co-treatment with a subthreshold dose of deprenyl plus tacrine was markedly more effective. Neither tacrine (5 mg/kg) nor deprenyl (10 mg/kg) alone reduced water maze deficits due to cholinergic-monoaminergic hypofunction, but co-treatment (using these doses) improved performance. Cholinergic-monoaminergic co-treatment may constitute a useful pharmacotherapy to correct physiological and behavioral dysfunction due to neurotransmitter deficiencies in AD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
