title: The effect of actinomycin D on estrogen-induced uterine blood flow.
abstract: The effect of actinomycin D on estrogen-induced uterine blood flow was studied in four nonpregnant, oophorectomized sheep, utilizing electromagnetic flow probes chronically implanted around the uterine arteris. Two hours after the intravenous injection of 1 mug of estradiol-17beta per kilogram of body weight, incorporation of [3H]-uridine into RNA was two- to threefold higher (2.7 plus or minus 0.4 S.E.M.) in the control horn than the uterine horn that had received an intra-arterial injection of actinomycin D. Actinomycin D had no effect on the estrogen-induced increase in uterine blood flow.
