Abstract: | Ischaemic injury was produced in the dog heart by occluding the left anterior descending coronary artery just below the second diagonal branch for the duration of 3 h. A prostacyclin analogue, ZK 36374 (Iloprost) was administered (10 micrograms/kg) just before the coronary artery occlusion. During 3 h occlusion ATP levels in the ischaemic area declined from 65.4 +/- 7.1 mM/g protein in sham-operated group to 31.5 +/- 5.2 microM/g protein in no-drug group and to 44.1 +/- 5.0 microM/g protein in Iloprost group. Creatine phosphate decreased from 112 +/- 14 microM/g protein, to 81 +/- 10 microM/g protein in no-drug group and to 95 +/- 12 microM/g protein in Iloprost group. The energy charge (ATP + 0.5 ADP/ATP + ADP + AMP) decreased slightly but not significantly in no-drug and Iloprost group. Three hours of LAD occlusion produced a significant fall in SOD activity in the ischaemic heart in comparison to the non-ischaemic and Iloprost-treated hearts. |
