头孢地嗪对免疫性肝损伤小鼠外周血T细胞亚群的影响

　　【摘要】 目的观察头孢地嗪对免疫性肝损伤小鼠外周血T细胞亚群的调节作用。方法 采用卡介苗联合脂多糖诱导法建立免疫性肝损伤的小鼠模型;将造模成功的免疫性肝损伤小鼠随机分为胸腺肽组、头孢地嗪大、中、小剂量组、头孢曲松组和生理盐水组，连续给药7 d，同时以正常小鼠作为对照组;采用免疫荧光染色技术，经流式细胞仪对小鼠的外周血T细胞亚群进行检测。结果 免疫性肝损伤合并败血症小鼠的CD3+(%)、CD4+(%)和CD8+(%)均明显低于正常小鼠，而头孢地嗪可有效地提高免疫性肝损伤合并败血症小鼠的CD3+(%)、CD4+(%)和CD4+/CD8+。结论 头孢地嗪可通过调整CD4+和CD8+之间的平衡，有效地提高机体的免疫功能。

　　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.
