Anxiolytic‐like effects and safety profile of a tryptic hydrolysate from bovine alpha s1‐casein in rats
Bibliographic record
Abstract
The anxiolytic activity and adverse benzodiazepine-like effects of a bovine alpha s1-casein tryptic hydrolysate (CH) were evaluated. The effects of CH orally administered at doses of 5 and 15 mg/kg were compared with those of diazepam (DZ) at 3 mg/kg in the conditioned defensive burying test. Rats treated either with CH at 15 mg/kg or with DZ showed a decrease in anxiety. A drug-related difference was observed in terms of duration, as the anxiolytic-like action of CH was maintained after 7 days with twice-daily administration, whereas that of DZ was not. CH and DZ were then evaluated for their potential effects on memory in a passive avoidance paradigm. CH-treated rats had significantly longer latencies before entering the dark compartment where they were previously delivered a shock, indicating better retention relative to DZ-treated rats. In the final test, CH and DZ were evaluated for place preference, an index of the possible addictive potential of these substances. DZ-treated rats spent more time in the compartment associated with drug exposure than control rats. This effect was not found in CH-treated rats. Thus, CH did not display side effects associated with DZ, despite its affinity for gamma-aminobutyric acid(A) (GABA(A)) receptors. Specific linking of CH on GABA(A) receptor function involved in anxiolysis, but not on that implied in memory-impairing effects, may be hypothesized to explain its specific activity. This profile might render it advantageous for nutritional purposes.

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.
