Preliminary study of liver targeting interferon on the immune toxicity of mice / 中国生化药物杂志

ABSTRACT

Objective To evaluate the immunotoxicity effect of Liver targeting interferon (IFN -CSP) on mice.Methods Mice were randomly divided into five groups:low, middle and high dose of IFN-CSP, solvent control group(saline) and Positive control group (cyclophosphamide).They were injected subcutaneously for 2 weeks.Delayed hypersensitivity test was used to determine the cell immunefunction and plaque forming cell assay was used to determine the humoral immune function.Results There was no significant difference of the the index of immune organ and the ear swelling degree between IFN-CSP groups and control group.There was also no significant difference on hemolytic plaque test between them.Conclusion IFN-CSP has no significant effect on both cellular immunity function and humoral immune function of mice, this results will provides the basis for further safety evaluation.
