ResumoThe cyclamate, a sweetner substance derived from N-cyclo-hexyl-sulfamic acid, is largely utilized as a noncaloric artificial edulcorant in foods and beverages as well as in the pharmaceutical industry.The objective of this study was to evaluate karyometric and stereological alterations in the rat fetal pancreas resulting from the intraperitoneal administration of sodium cyclamate.The exocrine pancreas of ten fetuses of rats were evaluated, five treated and five controls chosen at random, in which five rats that received from the 10th to 14th days of pregnancy an intraperitoneal daily injection of sodium cyclamate at 60 mg/Kg of body weight during 5 days.At the 20th day of gestation, the animals were removed and weighed, as were their placentas; the length of the umbilical cords also were measured.After the laboratory processing, semi-seriated 6mm cuts stained with haematoxyline and eosine were performed.In seven karyometric parameters (major, minor, and medium diameters, volume, area, perimeter, and volume-area ratio), the increase was statistically significant in the treated group when compared with control group.Stereological parameters showed in the treated group a significant increase in the cellular volume and a significant reduction in the numerical cellular density.These results showed that the sodium cyclamate in pregnant rats led to retardation of fetal development and hypertrophy in the exocrine pancreas of the rat fetuses.
