title: [Serum levels of soluble intercellular adhesion molecule-1 in patients with cerebral infarct].
abstract: To observe the changes of the levels of soluble intercellular adhesion molecule-1(sICAM-1) in serum of patients with cerebral infarct and to explore the effect of sICAM-1 on cerebral infarct.
  
  
  
  The serum levels of sICAM-1 in 55 patients with cerebral infarct both in acute stage(within 2 days) and convalescence(2 weeks after attack) were detected by using ELISA. At the same time, we compare the results with those of 32 patients having other neurologic diseases(20 patients with sciatica, 12 with trigeminal neuralgia) and 30 healthy subjects.
  
  
  
  (1) The serum levels of sICAM-1 of patients with cerebral infarct (acute stage: 766+/-179 microgram/L, convalescence: 602+/-155 microgram/L, respectively) were significantly higher than those of the control groups(530+/-77 microgram/L and 521+/-116 microgram/L, respectively, P<0.01). (2)There was a positive correlation of SICAM levels with the amount of leukocytes in acute stage(r=0.285,P<0.05), but negative correlation to clinical severity of cerebral infarct(r= 0.333,P<0.05). And there was no significant correlation between the level of sICAM-1 and the levels of cholesterol and triglyceride in serum(r= 0.042 and r=0.061, respectively, P>0.05). (3)There was no significant difference between sICAM levels of patients of cerebral cortex infarct and those of patients with basal ganglia infarct(773+/-178 microgram/L and 758+/-183 microgram/L, respectively, P>0.05). (4)The levels of sICAM-1 between patients of cerebral infarct with or without hypertension were no significant difference(774+/-189 microgram/L and 754+/-165 microgram/L, respectively, P>0.05).
  
  
  
  The levels of sICAM-1 increase significantly in patients with cerebral infarct. sICAM-1 may participate in the pathophysiologic process through inflammatory mechanism.
