[Change in the shape and volume of the secretory cells of the mammae in the course of the secretory cycle].
Changes occurring in the acini due to oxytocin were studied using the vital photometry and the morphometric analysis of materials obtained by biopsy. At the initial stages of the functional activation, the secretory cells become cylindric, their volumes simultaneously increasing. A study of intercellular interrelations using the atropine blockade of cholinoreceptors, revealed the lack of activation of the secretory cycle which suggests the functional dissociation of contractile and secretory functions of the cell alveolar complex.
