Percentage increase in the ratio of the infused and non-infused arms during graded acetazolamide infusion (left panel), both in the absence (•/solid line) as well as during concomitant infusion of glibenclamide (○/dashed line) and during graded sodium nitroprusside infusion (right panel), both in the absence (•/solid line) as well as during concomitant infusion of TEA (○/dashed line) are presented as mean±s.e.mean. The P-value refers to the statistical difference between conditions for these responses as analysed by repeated measures ANOVA.
