Reported findings and study design
Tactivin restored learning after thymectomy in young rats, whereas splenic polypeptides did not. The reported treatment was 0.5 mg/kg for one month.
Rats thymectomized at three weeks of age; active-avoidance learning assay.
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Active-avoidance learning | Restored with Tactivin; splenic polypeptides ineffective | |
| Reported regimen | 0.5 mg/kg for 1 month after surgery |
An animal thymectomy model; no effect size, group counts or human cognitive outcomes are supplied in the indexed abstract.
