Determination of effects of chemical agencies on liver fibrosis models frequently used in different dose and time periots

Abstract

Aim: In this study, it was aimed to reveal a more effective model depending on the dose and time by evaluating histopathological properties and biochemical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, triglyceride, cholesterol in carbon tetrachloride and thioacetamide (CCl4 and TAA) models. Method: Rats were divided into three groups for each model and intraperitoneally (i.p.) injected with CCl4 (0.5 ml/kg, 1.0 ml/kg, 2.0 ml/kg) and TAA (100 mg/kg, 200 mg/ kg, 300 mg/kg) for 4, 6 and 8 weeks, three times weekly, respectively. Results: In the biochemical investigation, ALT and AST values in the only 0,5 ml CCL4 of groups for 6 and 8 weeks and were found to have significant differences compared to the control groups (p <0.05), while the other biochemicals parameters values did not reveal significant difference in the groups (p >0.05). According to the results of the histopathology in the liver tissues, both the control groups showed a normal histological feature. The hepatofibrotic alterations were remarkable in the CCl4 and TAA models fibrosis depending on the increasing dose and time in all of the groups. Conclusion: Our results showed that the dose and time were reached up to until the cirrhosis for eighth week. These results would be a helpful reference for hepatofibrotic studies.
