Objective To understand the pathogenetic role and clinical significance of interleukin 6(IL- 6 ),tumor necrosis factor(TNF) and soluble interleukin- 2 receptor(sIL- 2R) in patients with cerebral infarction(CI) .Methods The IL- 6,TNF and sIL- 2R levels were measured in 46 CI patients with ELISA. Results The serum IL- 6,TNF and sIL- 2R levels of CI group were much higher than those of controls group .The variation of IL- 6,TNF and sIL- 2R levels was closely related to the size of cerebral infarction. The serum IL- 6,TNF and sIL- 2R levels of recovery period were much lower than those of acute period in patients with CI .Conclusions The IL- 6 ,TNF and sIL- 2R take part in the pathologic process after CI .The measurement of IL- 6, TNF and sIL- 2R is useful in determining the size of cerebral infarction.
