Abstract
Proliferol is an investigational new drug containing lidocaine hydrochloride 0.25%, dextrose 12.5%, glycerin 12.5%, and phenol 1.0% in aqueous solution. Despite extensive human experience with similar drugs administered by intraligamentous injection for chronic musculoskeletal disorders, little is known concerning preclinical toxicity. The purpose of this study was to assess the acute toxicity of intramuscular Proliferol in 96 (48 male, 48 female) Charles River strain rats, which were randomly assigned to low- (1x), medium- (5x), or high- (10x) dose Proliferol (derived from a human dose of 20 ml on a volume per bodyweight basis), or high-dose saline placebo. Observations included clinical observations, biochemistry, hematology, urinalysis, and full histopathology after 24 h or 14 days. There were no signs of ill health or reaction to treatment, and gait and body temperature were within normal limits. Biochemistry findings at 24 h included elevated aspartate aminotransferase, alanine aminotransferase, and haptoglobin; at 14 days all values were within normal ranges. Urinalysis findings at 24 h included increased urobilinogen and blood in all dose groups compared with placebo. Urine concentrations of phenol and lidocaine were greatest at 2 h and absent at 24 h. Histopathology findings included localized acute inflammatory soft tissue changes at the injection sites at 24 h and skeletal muscle regeneration at 14 days, which were consistent with the anticipated mechanism of action of Proliferol. There was no evidence of systemic toxicity from intramuscular injection of Proliferol in rats at up to 10x the human dose.

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 it
