Pulmonary responses to nutritional restriction and hyperoxia in premature rabbits

Abstract: Objectives: To analyze the effects of nutritional restriction and hyperoxia on lung weight and pulmonary morphometry in premature rabbits during the first 11 days of life.Methods: New Zealand White rabbits were delivered by C-section at 28 days gestational age and randomized into four groups: control diet and room air, control diet and hyperoxia (> 95% O 2 ), nutritional restriction and room air and nutritional restriction and hyperoxia (> 95% O 2 ). Nutritional restriction was achieved by reducing all nutrien… Show more

“…In a contradictory statement to this author, in this study, there was a statistically significant difference in atelectasis between groups C and D, found in only one animal of group C. A likely hypothesis for this result is that inside the chamber were the presence of nitrogen, since during the experiment was not possible to have a pulse of air to the measurement of gases 8 . The nitrogen did not participate in gas exchange between alveoli and alveolar capillaries; then it helps maintain lung volume.…”

“…Sabese que a ressecção do pulmão em animais jovens resulta em um imediato crescimento e expansão da área da superfície de trocas gasosas no pulmão restante. Ainda mais relevante para o artigo sobre efeitos nutricionais no desenvolvimento do pulmão publicado por Mataloun et al 1 no Jornal de Pediatria são os estudos sobre os efeitos da privação nutricional no pulmão adulto. A autópsia de seres humanos que morreram de fome no Gueto de Varsóvia na Segunda Guerra Mundial mostrou que eles tinham enfisema 2 .…”

“…Esses fatores sem dúvida contribuem em graus variados para o desenvolvimento da displasia broncopulmonar (DBP) no pulmão do prematuro, Veja artigo relacionado na página 179 ainda na fase sacular. Mataloun et al 1 relatam que a privação nutricional e a exposição hiperóxica interferem na alveolarização do pulmão do coelho prematuro. Esses resultados são consistentes com os resultados de outros estudos realizados com ratos e camundongos recém-nascidos.…”
