Utilização da glutamina no tratamento de lesões de isquemia e reperfusão no jejuno em eqüinos

Abstract: Sob anestesia geral e com controle da pressão arterial, 12 eqüinos foram submetidos simultaneamente a modelos de isquemia venosa e distensão intraluminal em segmentos do jejuno por 2 h, seguidos de 12 h de reperfusão. Seis eqüinos foram tratados com glutamina a 2% (50mg/kg) por via intravenosa e seis com solução fisiológica em igual volume, 1 h após o início da isquemia e às 6h de reperfusão. Foram colhidas amostras de tecido intestinal antes e com 2 h de isquemia e com 2 e 12 h de reperfusão para avaliações h… Show more

“…Only in the groups treated with PBS was a few haemorrhagic events in mucosa and submucosa observed, diverging from findings by Pagliosa et al (2009), who observed that in the group where venous occlusion was performed in order to cause I/R damage to the jejunum in horses, there was a significant presence of hemorrhage and edema in the mucosa and submucosa. These alterations are explained as a result of hypoxia followed by reperfusion which will cause damage to the vascular endothelium, loss of permeability and extravasation of red blood cells, and effects of reactive oxygen species (ROS) (Dabareiner et al 2001).…”

“…The histopathological classification of the injuries from the ischemic fragment was established according to an adaptation of the score proposed by Chiu et al (1970), shown in Table 2, as well as an adaptation of Pagliosa et al (2009), shown in Tables 3 and 4. To evaluate the presence of a mononuclear inflammatory process, a score was established (Table 5).…”
