An Extract from North American Ginseng Stimulates Spontaneous Immunity in Infant Mice: Sustained, Augmented Immunity in Adulthood Long after Withdrawal of the Extract
Bibliographic record
Abstract
The present study evaluated the effect of CVT E002, a proprietary extract of North American ginseng, Panax quinquefolius (CV Technologies, Inc., Edmonton, AB, Canada), in vivo, on the hemopoietic and immune cells when administered intraperitoneally to infant (pre-weaned) mice. The extract was administered to groups of mice daily, for 14 days, from 7 21 days after birth, the dosage being adjusted progressively according to body weight as the infants grew. At 21-26 days of age, the period immediately after the last of the injection, and at 7-8 weeks of age, long after the termination of CVT E002, the bone marrow and spleen were removed from treated and control mice (CVT E002-injected and vehicle-injected, respectively). The results revealed that CVT E002 stimulated only those cells acting as the first line of defense against cancer, i.e., natural killer (NK) cells and granulocytes when assessed immediately after termination of CVT E002. However, even more potentially significant, was the observation that in spite of withdrawing the agent at weaning (21 days of age), the influence of CVT E002 had indirectly continued to produce a significant augmentation in NK cells and granulocytes in adulthood. Thus, CVT E002 may be considered as a dietary additive, fortifying anti-cancer immunity during the critical infant/juvenile ages when, in humans at least, pediatric cancers such as leukemia, lymphomas, Wilms tumors and retinoblastoma are relatively frequent.

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.
