Proteinograma sérico de cordeiros nascidos a termo ou prematuros

Abstract

Ao final da gestação o neonato deve estar preparado, por meio de modificações funcionais e estruturais de órgãos e sistemas para dar início à vida extra-uterina. Os animais prematuros nascem antes deste processo estar completo, apresentando falhas na maturação. O objetivo deste estudo foi tentar identificar por meio da técnica de eletroforese em gel de poliacrilamida em dodecil sulfato de sódio (SDS-PAGE) proteínas de fase aguda, dentre elas, albumina, ceruloplasmina, transferrina, haptoglobina, glicoproteína ácida e imunoglobulinas A e G, que possam indicar a maturação no neonato prematuro. Os cordeiros foram divididos em seis grupos experimentais (parto normal, cesárea a termo, cesárea prematura, cesárea prematura com administração pré-parto materna de dexametasona, cesárea com administração de surfactante nos prematuros e cesárea prematura com administração pré-parto materna de dexametasona e surfactante ao neonato). Os resultados indicaram que após a administração de colostro, independente do tratamento, os valores séricos de proteína total e imunoglobulinas G aumentaram, indicando que há transferência de imunidade passiva através do trato gastrointestinal. A transferrina tem seus teores superiores em animais com idade gestacional superior, demonstrando potencial para ser utilizado como marcador de maturação neonatal.

At the end of gestation the neonate should be prepared, with functional and structural modifications of organs and systems to initiate extrauterine life. Premature animals are born before this process is complete, presenting maturation failures. The aim of this study was to identify an acute phase protein, such as albumin, ceruloplasmin, transferrin, haptoglobin, acid glycoprotein and immunoglobulins A and G, that demonstrates that different treatments indicate a maturation in the premature neonate using sodium dodecyl sulfate polyacrylamide gel electrophoresis technique (SDS-PAGE). The lambs were divided into six experimental groups (normal birth, full-term cesarean section at normal time of gestation, premature cesarean section, premature cesarean section whose mothers received prepartum dexamethasone, cesarean section giving surfactante to the prematures and premature cesarean giving prepartum dexamethasone to the mothers and surfactant to the neonate). The results indicated that after administration of colostrum, regardless of treatment, total serum protein and immunoglobulins increased, showing the transfer of passive immunity through the gastrointestinal tract. Transferrin has higher levels in animals with higher gestational age, demonstrating potential as a marker of neonatal maturation.
