Allopurinol Protects against Ischemia/Reperfusion-Induced Injury in Rat Urinary Bladders

Figure 1

Concentration-contraction curves obtained by cumulative addition of carbachol (CCh) to bladder strips. Each point represents the mean ± SEM of 15 bladder strips. indicates that I/R + Allo group is significantly different from I/R + S group (). † indicates that I/R + S group is significantly different from sham-operated groups (). Values are expressed as gram tension per 100 mg wet tissue. Sham-operated plus saline-pretreated group (Sham + S), ischemia-reperfusion and saline-pretreated group (I/R + S), and ischemia-reperfusion and allopurinol-pretreated group (I/R + Allo).
