title: [Expression of vascular cell adhesion molecule-1 in lung slices from antigen  sensitized rats and pharmacological modulation].
abstract: To investigate the expression of vascular cell adhesion molecule-1(VCAM-1) in lung slices from antigen  -sensitized rats and the modulation by drugs.
  
  
  
  In isolated lung slices from ovalbumin(OVA)-sensitized rats, the relative expression of VCAM-1 was determined after drug treatment and OVA challenge.
  
  
  
  The expression of VCAM-1 was enhanced in the sensitized rat lungs,and OVA challenge did not further increase the expression. Glycocorticosteroid dexamethasone and leukotriene cysLT receptor antagonist ONO-1078 inhibited the expression,but tachykinin NK-1 receptor antagonist SR-140333 had no such effect.
  
  
  
  VCAM-1 expression is enhanced in the sensitized rat lungs, and antigen challenge does not further up regulate the expression. Anti-inflammatory drugs have different effects on VCAM-1 expression. Dexamethasone and ONO-1078, but not SR-140333, can inhibit the expression.
