ABSTRACT
Os objetivos da pesquisa foram comparar os efeitos do uso da pentoxifilina por via portal ou periférica sobre a hemodinâmica, bem como eventual ação hepatoprotetora. Vinte e quatro cães foram submetidos a 45 minutos de isquemia, e divididos em três grupos: controle (CT), grupo pentoxifilina intra-hepático (PH) e grupo pentoxifilina sistêmico (PS). O grupo PS apresentou melhora significativa do débito e índice cardíaco aos 60 minutos de reperfusão em relação ao grupo CT. O fluxo venoso portal apresentou melhora significativa no grupo PS em relação ao grupo controle após 45 minutos de reperfusão. Nos grupos tratados com pentoxifilina os níveis séricos das enzimas hepáticas também foram menores que no grupo controle / Our objective was evaluated the potential systemic and regional benefits of intraportal or systemic infusion of pentoxifylline during an experimental model of normothermic hepatic ischemia. Twenty four dogs were evaluated in this study they were subjected to 45 minutes of ischemia. Previously to the Pringle maneuver the animals were randomized in three experimental groups: control (n=8), intraportal pentoxifylline (n=8) and systemic pentoxifylline (n=8). Systemic infusion of pentoxifylline improved significantly cardiac output, as well as portal vein blood flow when compared with control group. Intraportal infusion of pentoxifylline presented a partial increase of portal vein blood flow. In both groups treated with pentoxifylline, there was a significant decrease in markers of hepatic cell injury during the reperfusion period when compared with control group...
