Résumé :

The effects of 0.05 or 15 μg oestradiol, and of 5 or 50 μg nafoxidine on the uterus of immature rats were investigated. Nafoxidine appeared at least as efficient as oestradiol for the action on RNA, protein and glycogen content but was less efficient for inducing early increase in wet weight and in eosinophil migration into the uterus. If eosinophil counts in the deep stroma were considered, a strong parallelism was revealed between this response and the increase in wet weight. These results represent a further argument for a dissociation between early and late effects of oestrogen and for the existence of separate sites of hormone action. They also lend support to the hypothesis of a mediation of wet weight response by eosinophils.
