Abstract:
:The eicosanoids, leukotriene B4 (LTB4) and thromboxane A2 (TXA2), contribute to neutrophil adhesion and arteriole vasoconstriction, important microcirculatory events in ischemia-reperfusion (I-R) injury. The purpose of this study was to evaluate the effect of ketorolac on I-R injury of skeletal muscle. A videomicroscopic preparation of gracilis muscle in male Wistar rats (n=7) in two experimental groups was evaluated: Group 1-4 hr global ischemia only (19 arterioles, 19 venules), and Group 2-4 hr ischemia plus ketorolac (13 arterioles, 14 venules). Ketorolac (0.86 mg/kg, i.m.) was given 30 min prior to reperfusion. The number of neutrophils, rolling and adherent, was counted in 100-micron venular segments, and arteriole diameters were measured at 5, 15, 30, 60 and 120 min of reperfusion. The I-R-induced increase in neutrophil adhesion was significantly reduced by ketorolac, which significantly increased arteriolar vasodilation in the first 30 min of reperfusion and significantly reduced the I-R-induced vasoconstriction in arterioles at 30 min; this effect was lost at 1 hr of reperfusion. Although ketorolac augments immediate arteriole vasodilation and blocks subsequent vasoconstriction, this effect appears to be transient. These findings suggest that ketorolac may have potential as a treatment for I-R injury.
