Autores: Martins,Marielza R Ismael; Azoubel,Reinaldo.
The objective of this study was the evaluation of aspartame effects on morphometric alterations of the glomerulus, proximal and distal convoluted tubules and collecting ducts of the rat fetal kidney during organogénesis. Fifteen pregnant rats averaging 24 g body weight, were divided into 3 groups (n=5 each) of controls, rats treated with aspartame exposed to room temperature and rats treated with aspartame heated to 40°C. Animals were given 14mg / kg aspartame by the intragastric route on the 9th, 10th, and 11th days of pregnancy. Karyometric and stereological techniques estimated morphological changes. A significant decrease of fetal body weight was observed in the group given aspartame kept at room temperature, compared to controls. Karyometry permitted...
