摘要
Objective This study was designed to evaluate hematological disorders and the orchestrating roles of hepcidin and IL-6 in rat models of thioacetamide(TAA) and carbon tetrachloride(CCl_4) hepatotoxicity. Methods Rats were intraperitoneally injected with TAA(10 mg/100 g rat weight dissolved in isosaline) or CCl_4(100 μL/100 g rat weight diluted as 1:4 in corn oil) twice weekly for eight consecutive weeks to induce subchronic liver fibrosis. Blood and tissue samples were collected and analyzed. Results CCl_4 but not TAA significantly decreased the RBCs, Hb, PCV, and MCV values with minimal alterations in other erythrocytic indices. Both hepatotoxins showed leukocytosis, granulocytosis, and thrombocytopenia. By the end of the experiment, the erythropoietin level increased in the CCl_4 model. The serum iron, UIBC, TIBC, transferrin saturation%, and serum transferrin concentration values significantly decreased, whereas that of ferritin increased in the CCl_4 model. TAA increased the iron parameters toward iron overload. RT-PCR analysis revealed increased expression of hepatic hepcidin and IL-6 m RNAs in the CCl_4 model and suppressed hepcidin expression without significant effect on IL-6 in the TAA model. Conclusion These data suggest differences driven by hepcidin and IL-6 expression between CCl_4 and TAA liver fibrosis models and are of clinical importance for diagnosis and therapeutics of liver diseases.
