Resumo: | PURPOSE: To study the lesions in the lung of rabbits caused by ischemia/reperfusion hepatic (I/R) after the use of N-acetyl-cysteine (NAC). METHODS: Twenty-four rabbits distributed in two groups: control group GI (n = 12) 5% glucose solution and experiment group GII (n = 12) NAC. The animals were pre-anesthetized with 1% acepromazine maleate and anesthetized with ketamine 10% and 2% xylazine intramuscularly. The GI and GII were given glucose solution intravenously or NAC 15min before occlusion of the hepatic pedicle (30 min). After the period of reperfusion of 24h (n = 6) or 48h (n = 6), liver and lung samples were collected for histology and immunohistochemistry to assess the impairment of cell. RESULTS: The animals of GII and GII-24h-48h showed parenchyma liver close to normal, when using NAC. The GII and GII-24h-48h showed lower thickness of alveolar cells that GI and GI-24h-48h. The expression of caspase 3 in lung cells GII presented smaller value compared to the GI group. CONCLUSION: N-acetyl-cysteine administered 15min prior to the injury ischemia/reperfusion had a significant protective role by minimizing lung injury and apoptotic morphology in the period observed. |

MÉTODOS: Vinte e quatro coelhos distribuídos em dois grupos: Grupo controle GI (n=12) solução de glicose 5% e Grupo experimento GII (n=12) NAC. Os animais foram pré-anestesiados com maleato de acepromazina 1% e anestesiados com cloridrato de quetamina 10% e xilazina 2% via intramuscular. Os grupos GI e GII receberam solução glicosada ou NAC respectivamente via endovenosa 15min antes da oclusão do pedículo hepático (30 min). Após iniciou-se o período de reperfusão por 24h (n=6) ou 48h (n=6), terminada a reperfusão, amostras do fígado e pulmão foram coletadas para a histologia e imunoistoquímica para avaliar o comprometimento celular. RESULTADOS: Os animais do grupo GII-24h e GII-48h apresentaram arquitetura do parênquima hepático próximo do normal, quando se utilizou NAC. Os grupos GII-24h e GII-48h apresentaram menor espessura das células alveolares que os grupos GI-24h e GI-48h. A expressão da caspase 3 nas células pulmonares do grupo GII, apresentou valor menor comparada ao grupo GI. CONCLUSÃO: A N-acetil-cisteína administrada 15min prévios a lesão da isquemia/reperfusão teve um papel protetor significativo minimizando as lesões morfológicas e apoptóticas pulmonares nos períodos observados.2013-10-19T00:47:22Z2013-10-19T00:47:22Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCASTRO, Angela Potter de et al. he role of N-acetylcysteine in the lung remote injury after hepatic ischemia and reperfusion in rabbits.
