Effect of indomethacin (a prostaglandin synthetase inhibitor) on the permeability of blood-brain and blood-CSF barriers in rat.
Effect of indomethacin on the permeability of blood-brain and blood-csf barriers to Evans blue, bromophenol blue and horseradish peroxidase (HRP) was studied by administering the drug through right internal carotid artery, right external jugular vein and through intraperitoneal route in rats. Increased permeability was observed on internal carotid arterial injection but not following jugular vein or intraperitoneal injection. This increased permeability of blood-brain and blood-csf barriers following injection of indomethacin into the internal carotid artery is associated with a steep and sustained rise in mean arterial blood pressure (MABP), a feature not observed in bilateral adrenalectromised animals.
