摘　　要：The immunoregulating effect of Interleukin-1-receptor antagonist (ILlra ) in lupus-like NZB/W F, mice was investigated to find possible approach to prevent lupus nephritis. 12 female NZB/W F1 mice of 13 weeks were randomly divlded into 2 groups. Each mouse in the treated group was intraperitoneally injected wlth IL-lra once every 2 weeks for 3 times at the dosage of 100μg each time,while the control group was given injection of 0.1 ml normal saline. All the mice were killed at the age of 9 months and the irnmunologic function was examined.Results showed that this dosage could not completely prevent the development of lupus nephritis, but the renal damage was alleviated and the urine protein was decreased. Moreover, it could improve the immunofunction by significantly reducing the levels of serum IL-1 and obviously increase the activities of NK celIs and IL-2 induced by ConA in mononuclear cells of spleen. There was no significant difference in the levels of serum IL-6 and TNF-α between the treated group and control group. It is concluded that IL-lra has certain regulatory effect on the immunologic function of lupus-like NZB/W F, mice.The immunoregulating effect of Interleukin-1-receptor antagonist (ILlra ) in lupus-like NZB/W F, mice was investigated to find possible approach to prevent lupus nephritis. 12 female NZB/W F1 mice of 13 weeks were randomly divlded into 2 groups.
