Effects of rolipram on renal microvascular perfusion. A dose-finding study (A) was used to determine the efficacy of rolipram to prevent the decline in renal cortical microvascular perfusion. Rolipram was administered at the time of CLP (ip injection) and perfusion was measured at 6 h; n = 5 for Sham; n = 8 for CLP; n = 5–8 for CLP + Rolipram; p < 0.05 compared to Sham by two-way ANOVA; #this dose produced 70% lethality. The dose of 0.1 mg/kg was the lowest dose to prevent both the decline in vessels with continuous flow and the increase in vessels with no flow. Next, rolipram (0.1 mg/kg, ip) was administered at 6 h post-CLP and perfusion was measured at 18 h (B). Even with delayed administration, rolipram protected renal microvascular perfusion; p < 0.05 compared to Sham and CLP + Rolipram; #p < 0.05 compared to Sham and CLP; n = 5 for 18 h Sham; n = 6 for 18 h CLP; n = 5 for 18 h CLP + Rolipram.
