[Metoclopramide action on the mammary glands of albino rats in lactation or in early weaning: morphological study].
The authors performed an optical microscope study of the histological features of mammary glands of albino rats during lactation and after early weaning, whether or not treated with metoclopramide. They observed that in the lactation group, the alveoli and ducts of both treated and untreated rats were quite developed and contained eosinophilic secretion. In the early weaning group, they saw that stroma predominated over the parenchyma, mammary glands being little developed. In the treated group that was submitted to early weaning, there was a balance between stroma and parenchyma, the latter containing secretion in the lumen. Mammary glands were less atrophied in the treated early weaning group than in the untreated group.
