Abstract

The overall objective of this study was to determine whether peroral treatment with the 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitor fluvastatin influences the leukocyte-endothelial cell adhesion (LECA) observed in postcapillary venules of hypercholesterolemic rats. Rats were fed either normal chow or a chow supplemented with 1% cholesterol for 10 days. Leukocyte adherence and extravasation, leukocyte rolling velocity, red blood cell velocity, and vessel diameter were monitored in mesenteric venules superfused with either 100 nmol/L platelet-activating factor (PAF) or 20 nmol/L leukotriene B4 (LTB4). Hypercholesterolemic rats exhibited an exaggerated LECA response compared with their normocholesterolemic counterparts. In hypercholesterolemic rats, treatment with fluvastatin significantly attenuated the leukocyte-adherence responses to PAF and LTB4 as well as the leukocyte emigration response to LTB4. Fluvastatin treatment also inhibited the PAF- and LTB4-induced reductions in leukocyte rolling velocity. These findings indicate that fluvastatin blunts the inflammatory responses elicited in post-capillary venules by lipid mediators.
