Abstract
SEVERAL daily drug-susceptibility rhythms have been reported in rodents1–12. This report demonstrates the daily pattern in susceptibility to D-amphetamine sulphate as measured by percentage of mortality for normal rats housed in a light-dark (LD) environment, for rats maintained in continuous illumination (LL) and for blinded rats kept in continuous darkness (DD).
