Abstract
Morning changes in number of eosinophils were studied in 2 age groups of infants, in the absence of stimulation other than daily routine. Endogenous morning eosopenia, which is one of several physiological periodicities exhibiting 24-hour spacing in maturity, is not revealed in early infancy by tests employing the 06:30-09:30 sampling. By contrast, most infants older than 15 months show a marked decrease in number of eosinophils from 06:30 to 09:30 of the same morning. The significance of these findings is discussed.Keywords
