The degranulatory activity of estradiol was tested on blood eosinophil leukocytesin vivo andin vitro. Treatment of adult ovariectomized rats with 30 μg estradiol/100 g body wt. increased the percentage of degranulated eosinophils from 10% to about 70% at 6 or 24 h after treatment, and increased the rate ofin vitro eosinophil degranulation of those(More)
