ABSTRACT
AIM: To investigate the effects of IL-13 on expression of IL-1? in acute renal ischemia/reperfusion injury. METHODS: Fifty-seven male Wistar rats were randomly divided into 8 group: normal group,sham operation group, ischemia group, ischemia/reperfusion injury group(I/R), normal saline(NS)-treated group 1(C-1), NS-treated group 2(C-2),IL-13-treated group1(T-1)and IL-13-treated group 2(T-2).Rats were subjected to 45 min bilateral renal ischemia followed by reperfusion. rmIL-13 (1.5 ?g/50 g body weight )was injected into the renal arteries through the abdominal aorta before ischemia(T-1) or immediately afterischemia(T-2).The serum level of IL-1? and the renal expression of IL-1? were determined in each group at 24 h post-ischemia. In addition, BUN,Cr and renal histology were also measured. RESULTS: (1)The serum level of IL-1? [C-1to T-1: (27.13?5.51) ng/L to (14.05?3.82) ng/L, P
