The BALB/c mice were immunized with rMS-Sj26GST and rBCG-Sj26GST vaccine inSchistosoma japonicum by subcutaneous injection. After they were immunized for 8 weeks, the eye-balls were removed to get blood and macrophages of abdominal cavity and spleen cells were harves-ted. The lymphocytic stimulating index (SI) was used to measure the cellular proliferating abilityand NO release was used to measure the phagocytic activity of the macrophages. By using ELISAkit, the levels of interleukin-2 (IL-2) and interferon-γ(IFN-γ) in serum and the splenic lymphocyt-ic cultured supernatant were detected. The results showed that after the mice were immunized with106 CFU of rMS-Sj26GST and rBCG-Sj26GST vaccine separately by subcutaneous injection, prolif-erating ability of splenic lymphocytes in the mice showed no difference (P＞0.05), but both weresignificantly increased as compared with that in the control group(P＜0.05); The contents of NOin the intraperitoneal macrophages of rMS-Sj26GST vaccine group were significantly lower than inthe control group (P＜0. 001) and rBCG-Sj26GST vaccine group (P＜0. 01); The levels of serumIL-2 in the rMS-Sj26GST vaccine group were significantly increased as compared with that in thecontrol group (P＜0. 001), vector group (P＜0.01) and rBCG-Sj26GST vaccine group (P＜0.05);The contents of serum IFN-γ in the rMS-Sj26GST vaccine group were significantly increased ascompared with that in the control group (P＜0.01) and rBCG-Sj26GST vaccine group (P＜0.05).The contents of IFN-γ in the cultured supernatant were significantly lower than those of rBCG-Sj26GST vaccine group (P＜0. 001), but were significantly increased as compared with that in thecontrol group (P＜0.01). It was indicated that both vaccines could enhance the immune response ofthe mice, but rMS-Sj26GST vaccine had stronger immunogenicity than rBCG-Sj26GST vaccine.
