Abstract
Acute liver injury is a debilitating disorder associated with loss of synthetic and detoxifying functions of the liver. This investigation was designed to assess cytoprotective efficacy of daily oral tiron (300 mg/kg) and daily oral methyl palmitate (300 mg/kg) against acetaminophen-induced acute liver injury. Rats were orally pretreated with either tiron or methyl palmitate at doses (300 mg/kg) for 7 days prior to oral acetaminophen (3 g/kg). Biochemical assay of markers of hepatotoxicity indices and oxidative stress was undertaken. Expression of inflammatory cytokine IL-6 was also evaluated. Histopathological examination of liver specimens was carried out as well. Both methyl palmitate and tiron significantly reversed the acetaminophen-induced elevation of biochemical markers (ALT, AST, and ALP) with restoration of SOD levels. Serum albumin levels and GSH liver contents increased, but in a nonsignificant manner. Moreover, methyl palmitate and tiron significantly decreased the level of serum LDH and serum IL-6 levels. Histopathology revealed that tiron markedly reduced the extent of acetaminophen-induced necrosis and methyl palmitate moderately decreased the necrosis in liver tissue. Methyl palmitate (300 mg/kg) and tiron (300 mg/kg) demonstrated promising hepatoprotective effects against acetaminophen-induced acute liver injury via modulation of inflammatory response and alleviation of the oxidative stress, allowing the preservation of hepatic functions.
