摘　　要：AIM: To observe the protective effect of rhIL-1β on pancreatic islets of alloxan-induced diabetic rats. METHODS: Protection of rhIL-1β on pancreatic islets of alloxan-induced diabetic rats (n=5) was demonstrated with methods of immunohistochemistry and stereology. The concentration of serum glucose was measured by GOD method and that of serum insulin by RIA. RESULTS: The concentration of serum glucose increased but that of insulin decreased after administration of alloxan (150mg/kg), and the volume density and numerical density of the islets were zero. In rhIL-1β pretreated rats, although the concentration of serum insulin decreased (from 11.9±3.0mIU/L to 6.1±1.6mIU/L,P<0.05), that of glucose was at normal level compared with the control group. As compared with alloxan group, the concentration of serum glucose in rhIL-1β pretreated rats decreased (from 19.4±8.9mmol/L to 12.0±4.0mmol/L, P<0.05) and the volume density increased(0/L to. 1/L, P<0.05). CONCLUSION: rhIL-1β pretreatment may have protective effect on the islets of alloxan-induced diabetic rats.AIM:To observe the protective effect of rhIL-1β on pancreatic islets of alloxan-induced diabetic rats.
