Moderate physical training attenuates the effects of perinatal undernutrition on the morphometry of the splenic lymphoid follicles in endotoxemic adult rats.

Background/aims: Physical training is a well-known inducer of positive physiological adaptations. The effects of moderate physical training on the morphometry of splenic lymphoid follicles of endotoxemic rats submitted to a perinatal low-protein (LP) diet were evaluated.

Methods: Male Wistar rats were divided into two groups according to their mother's diet (17% casein, control, C) and, undernourished (8% casein, LP diet).

Short- and long-term effects of a neonatal low-protein diet in rats on the morphology of the larynx.

Objective: The aim of this study was to investigate the short- and long-term effects of a maternal low-protein diet during lactation on offspring laryngeal morphology. Our hypothesis was that a neonatal low-protein diet during the critical period of development alters micro- and macroscopic structures of the larynx in adult rats.

Methods: Male Wistar rats were assigned to a control (casein 17%, n=24) or low-protein (casein 8%, n=24) group according to their mother's diet during lactation.
