Post-ischaemic treatment with the cyclooxygenase-2 inhibitor nimesulide reduces blood-brain barrier disruption and leukocyte infiltration following transient focal cerebral ischaemia in rats
It has been shown that after several hours of the onset of ischemia, there is a significant disruption of the blood-brain barrier (BBB) followed by a massive infiltration of polymorphonuclear (PMN) leukocytes (Rosenberg et al. 1998;Batteur-Parmentier et al. 2000;Martin et al. 2006).
