Fig 1 (a) Histogram showing the experimental protocol from part 1. Con, control; He, helium; LPC, late preconditioning; NS-398, selective COX-2 inhibitor (5 mg kg−1 i.p.) administered 30 min before preconditioning. Spontaneously breathing rats received helium or oxygen 24 h before ischaemia/reperfusion. (b) Histogram showing the experimental protocol from part 2. All rats were treated on three subsequent days, either with 30% helium or with 30% oxygen, interspersed by 24 h between each treatment before ischaemia/reperfusion.
