“…Our work confirms the anti-TNF-α, anti-IL1β and anti-IL-6 effects observed after using PTX on severe organ ischemia in rats. 11,12,15,20 The TNF-α findings, although not novel from the perspective of the effect of PTX since they were reported by Sullivan and associates in 1988, 33 previously had not been reported after severe intestinal ischemia and PTX treatment, except for the work of Yamamoto. 15 The implications associated with these findings are significant because the above-mentioned The improvement in the laser Doppler vascular flow of normal and ischemic intestines indicates a relation between vascular flow and molecular response noted in these animals.…”

“…1,2 In addition, and as a consequence, many molecular markers have been identified as key contributors to I/R. 8,10,[12][13][14][15][16][17]19,20 Pentoxyphilline (PTX) a methylxanthine hemorheologic compound that reduces blood viscosity and improves erythrocyte deformability, began its use in Europe for intermittent claudication in 1972. 22 Other demonstrated effects (eg, vasodilatation and inhibition of neutrophil adhesion) prompted its potential interest as a beneficial compound for various I/R conditions.…”

“…El-Ghoneimi et al 34 demonstraram a inibição da transcrição gênica do TNFα em ratos administrando pentoxifilina na dose de 50 mg/Kg em dois períodos: trinta minutos antes do início da isquemia e 30 minutos antes do período da reperfusão. O mesmo autor verificou a redução da desidrogenase lática e dos níveis de transaminases melhorando, assim a sobrevida dos animais 34 .…”

“…O mesmo autor verificou a redução da desidrogenase lática e dos níveis de transaminases melhorando, assim a sobrevida dos animais 34 . O efeito citoprotetor da pentoxifilina na lesão de I/R hepática poderia estar relacionado, como mencionado acima, ao aumento na produção de prostaglandinas (PGE2) 57 .…”
