the fact that the change in phospholipase a2 occurs soon after endotoxin administration and that the change in phospholipase is blocked by protective doses of indomethacin suggests that phospholipase a2 activation may be an important initial event in the lethal action of endotoxin , and that the protective effects of indomethacin may be directly related to inhibition of phospholipase a2 activity .
