CURI, Viviane et al. Histometric Study of Alveolar Bone in Rats Submitted to Ethanol During Lactation. Int. J. Morphol. [online]. 2008, vol.26, n.4, pp.945-950. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000400026.
The present work studied the adverse effects of maternal exposure of rats to alcohol during lactation, on the development of their off spring. Histometric evaluation by karyometry and of the alveolar bone at the level of the first upper molar of the sucking was perfomed. Two groups of animáis, one coming from mothers exposed to drinking water containing 20% ethanol during the total lactation period and the other of controls coming from mothers receiving only alcohol-free drinking water during this period. On the 21 first day of lactation the young of each group were aleatorily selected and following anesthesia, their heads severed; after histological treatment, serial 6 μm sections on the frontal plañe at the molar level, stained with hematoxilin and eosin, were obtained. The experimental results produced, suggest that sucking from ethanol-treated mothers, show retarded post-natal growth, their alveolar bones presenting scarce, little calcified trabeculae, and a more abundant bone marrow compared to controls.
