Abstract

Malnutrition is responsible for half of the 11 million children under age 5 who die every year. Malnutrition is a determining factor for plant diseases of the respiratory system and nervous. We assessed the effects of malnutrition and renutrition tracheal plexus of rats. We used offspring of the groups: nourished (N) (20% casein), undernourished (UN) (5% casein) and renourish (R) (fed 5% casein up to 21 days and 20% up to 42 days ). The specimens were evaluated by NADH-d, NADPH-d, AChE, SP, VIP and SEM. There was a weak reactivity to AChE neurons of group UN. There was no difference in the number of neurons and ganglia (NADH-d and NADPH-d). The neuronal area was higher in group N (NADH-d and NADPH-d). Ganglia were higher in group N (NADH-d) and no difference between the ganglia reactive to NADPH-d. In half of the thoracic trachea was about 80% of neurons and ganglia (NADH-d and NADPH-d). Protein malnutrition altered components of the tracheal plexus and renutrition was responsible for the partial recovery of this development. (AU)
