ABSTRACT

Objective To study the regulatory effect of cefodizime on the T-lymphocyte subsets of peripheral blood in mice with immunological liver injury.Methods The mouse model of immunological liver injury was induced by Bacillus Calmette Guerin and Lipoposaccharide.The study was conducted by using completely random design.The mice with immunological liver injury were divided into thymosin group,cefodizime high-,medium-,low-dose groups,ceftriaxone group and the normal saline group.The six groups were continuously administered agents respectively for 7 days,and T-lymphocyte subsets of peripheral blood in mice were determined and contrasted with those of the normal mice treated with normal saline on the 7th day.Flow cytomytry was used to determine the effects of cefodizime on T-lymphocyte subsets of peripheral blood in mice by using immuno-fluorescence technique.Results The immunological liver injury mice were deficient because their CD3+(%),CD4+(%),CD8+(%) and the ratio of CD4+CD8+ were lower than those of the normal mice.Cefodizime effectively increased CD3+(%),CD4+(%) and the ratio of CD4+CD8+ of the mice with immunological liver injury.Conclusion Cefodizime effectively improves the immune function of the host by regulating the balance between CD4+ cell and CD8+ cell.
