Abstract
In this experimental study we studied the effect of verapamil and iloprost on endothelin release in ischemia/reperfusion (IR) injury of the rat intestine. Endothelin levels in the portal blood and malondialdehyde (MDA), PGE2, and LTC4 levels in the intestinal tissue were determined. The MDA levels increased in the control group and this increase was reversed with iloprost, verapamil and both. The change in the LTC4 levels was insignificant between the groups. Iloprost reduced PGE2 and endothelin release, but verapamil was not as effective and no synergistic effect was encountered. The increased PGE2/LTC4 ratio was also reversed in the experimental groups, verapamil being less effective. Endothelin release seems to be related to both PGE2 levels and the PGE2/LTC4 ratio after mesenteric IR injury.
