Carbon tetrachloride: a hepatotoxin causes oxidative stress in murine peritoneal macrophage and peripheral blood lymphocyte cells.

Context: Carbon tetrachloride (CCl4) is frequently used as a chemical inducer of tissue damage. Their effects on mouse peritoneal macrophages and also in peripheral blood lymphocytes are still unknown. Objective: Therefore we tried to focus on intracellular oxidative stress produced by CCl4 in mouse macrophage and lymphocyte cells. Methods: Intraperitoneal administration of CCl4 induces intracellular superoxide anions production in mouse macrophages and peripheral blood lymphocytes and leads a subsequent lipid peroxidation and protein oxidation. N-acetyl cystein (NAC) and vitamin C were administered intraperitoneally at a dose of 150 mg/kg and their effect on demodulating the oxidative stress is also checked. Result and discussion: Several in vitro approaches have already been established as a free radical scavenging models, but this free radical screening models is not always correlated with the in vivo screening models. NAC and vitamin C were administered intraperitoneally and significant reduction of the oxidative stress in term of scavenging of toxic superoxide anion observed in both the macrophages and lymphocytes. Conclusion: Therefore we are hopeful that our work will light a new insight into the screening of in vivo free radical scavenging model for evaluating anti-inflammatory compounds.
