【Abstract】 Objective] To detect the levels interleukin-4(IL-4) in sera from laboratory bred Microtus forits(BMF) before and after infection by Schistosoma japonicum.[Methods] Indirect ELISA was performed to detect the levels of IL-4 in sera from BMF and albino mice (AM) before infection by shistosoma japonicum (BMF 0, AM 0) and 9 d(BMF i9 ,AM i9 ) and 16 d(BMF i16 ,AM i16 ) after infection.[Result] The average level of IL-4 in sera of BMF i9 (131.94 pg/ml) was significantly higher than those of BMF 0 (52.59 pg/ml) and BMF i16 (58.16 pg/ml), and compared with AM, that of BMF 0 was 4.2 times that of AM 0 (12.43 pg/ml) and that of BMF i9 3.0 times that of AM i9 (44.53 pg/ml).[Conclusion] The average level of IL-4 of BMF was significantly higher than that of AM, and during the early stage of infection, the levels of IL-4 of BMF increased significantly, possibly showing that IL-4 played an important role in the resistance of M. fortis to S. japonicum infections.更多还原
