Intrauterine exposure to a high-fat diet, with different levels of lipids, and its gastrointestinal repercussions: a model of fetal programming in rats.

It is known that adverse stimuli, such as altered diets during pregnancy and lactation can result in deleterious effects on the progeny. The aim of this study was to evaluate the possible gastrointestinal repercussions in the offspring of Wistar rats exposed to high-fat diets. Pregnant rats were divided into three groups: normolipidic diet (3.

Effects of maternal hypothyroidism in the gastrointestinal system of male young offspring from Wistar rats.

Alterations in the maternal environment may impact on the fetal development. The objective of this study was to investigate the gastrointestinal consequences of maternal hypothyroidism for the male offspring from Wistar rats. The pregnant rats were divided into three groups: control (C - received water), experimental 1 [E1 - received methimazole (MMI) solution] during gestation and lactation, and experimental 2 (E2 - received MMI solution) during gestation.
