Effect of indomethacin on responses of sheep isolated coronary artery to arachidonic acid.


Indomethacin (2.8 mumol/l) did not consistently affect basal tone of sheep coronary artery strips, while a ten-fold higher concentration increased tension in 50% of the preparations tested. When acetylcholine was used as a spasmogen, oscillations in induced tone and relaxations produced by arachidonic acid (6.6 mumol/l) were abolished by indomethacin, 2.8… (More)
