Abstract
Chromosomal and nuclear aberrations in bone marrow cells were studied in hybrid mice of genotype (C57BL x C3H)F1 following treatment with specific cannabinoids. In the subacute series, mice were treated for 5 consecutive days with delta 9-tetrahydrocannabinol (THC), cannabinol or cannabidiol at a dose of 10 mg/kg, the percentage of micronuclei in cannabinoid-treated mice was 3- to 5-fold greater than in the dimethyl sulfoxide controls. In the acute series, polychromatic erythrocytes were scored after a single exposure. In one acute series there was an approximately twofold increase in the incidence of micronuclei in the cannabinoid-treated mice; in the other acute series of cannabinoid-treated animals the micronuclei values were as high as 6 times the control values. Interaction between dose and frequency of exposure was assessed for THC; the number of micronuclei was affected by THC dosage, but not by frequency of exposure. Further confirmation of nuclear aberrations was obtained from assessment of bone marrow mitosis. In this limited study of mitotic cells the incidence of metaphase aberrations in cannabinoid-treated animals was 5-7 times greater than in controls.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
