title: Granulocyte-colony stimulating factor administration ameliorates liver regeneration in animal model of fulminant hepatic failure and encephalopathy.
abstract: It has previously been shown that recombinant granulocyte-colony stimulating factor (rG-CSF) accelerates and enhances hepatocyte proliferation in partially hepatectomized rats. In the present study, we examined the effect of rG-CSF administration on liver injury, regeneration, and survival outcome in an experimental rat model of fulminant hepatic failure (FHF) and encephalopathy induced by repeated injections of thioacetamide (TAA). FHF was induced in adult male Wistar rats by three consecutive intraperitoneal injections of TAA, at intervals of 24 hr. The animals were also injected with either saline or rG-CSF. Serum biochemical parameters and blood ammonia levels, liver histology, stage of hepatic encephalopathy, and survival were statistically significantly improved in TAA-intoxicated and rG-CSF-treated rats compared to TAA-intoxicated and saline-treated ones. Furthermore, rG-CSF not only ameliorated the histologically evident liver injury in a statistically significant manner but also enhanced the proliferative capacity of the hepatocytes. Our data confirm the beneficial effect of rG-CSF administration in this animal model of FHF and encephalopathy, supporting evidence for a possible use of rG-CSF as supportive therapy in the management of FHF.
