Résumé : Pretreatment with propranolol does not modify the estrogen-induced uterine eosinophilia, the water imbibition effect, nor the increase in uterine RNA and protein content. This confirms the independence of these parameters from the estrogen-induced early increase in uterine cAMP, since, when observed, the latter is suppressed by propranolol pretreatment. © 1977 Experientia.
