Abstract in Portuguese
A desnutrição é responsável pela metade das 11 milhões de crianças abaixo de 5 anos de idade que falecem todo ano. A desnutrição é fator determinante para instalação de doenças do sistema respiratório e nervoso. Avaliaram-se os efeitos da desnutrição e renutrição no plexo traqueal de ratos. Foram utilizados filhotes dos grupos: nutridos (N) (20% de caseína), desnutridos (D) (5% de caseína) e renutridos (R) (alimentados com 5% de caseína até 21 dias e com 20% até os 42 dias). Os espécimes foram avaliados pela NADH-d; NADPH-d; AChE; SP; VIP e MEV. Observou-se fraca reatividade à AChE dos neurônios do grupo D. Não houve diferença do número de neurônios e gânglios (NADH-d e NADPH-d). A área neuronal foi maior no grupo N (NADH-d e NADPH-d.) Os gânglios do grupo N eram maiores (NADH-d) e sem diferença entre gânglios reativos à NADPH-d. Na metade torácica da traquéia havia cerca de 80% dos neurônios e gânglios (NADH-d e NADPH-d). A desnutrição protéica alterou componentes do plexo traqueal e a renutrição foi responsável pela recuperação parcial deste desenvolvimento.

Abstract in English
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.
