Silibinin Effect on Fas/FasL, HMGB1, and CD45 Expressions in a Rat Model Subjected to Liver Ischemia-Reperfusion Injury
2018
ABSTRACTPurpose: We investigated the hepatoprotective effect of Silibinin (SLB) to ischemia-reperfusion (I/R) rat model, by evaluating the histological expression of the tissue markers Fas/FasL, HMGB-1 and CD45, and SLB pharmacokinetics. Methods: Seventy-three Wistar-type male rats were randomized in 11 groups: Sham control group (open-close laparotomy); four I/R control groups (laparotomy, 45 min vascular occlusion, reperfusion, euthanasia after 60, 120, 180, and 240 min); four SLB (Si) groups (laparotomy, 45 min vascular occlusion, IV administration of SLB, reperfusion, euthanasia after 60, 120, 180, and 240 min); two SLB pharmacokinetics (PK) groups (IV administration of SLB, euthanasia after 45 and 240 min). Results: Fas/FasL increased with reperfusion time in I/R control groups and decreased in the Si groups, reaching, respectively, the highest and lowest values at 240 min of reperfusion (p <.0001). HMGB1 and CD45 increased with time in the I/R control groups up to 240 min and decreased in the Si gro...
