Microvascular blood flow was measured in the nasal epithelium of P1 rabbit kits using laser Doppler probe (A) and was similar after intranasal administration of equal volumes saline or sodium nitrite at 21°C (B). The order of saline or sodium nitrite was switched in the left and right nostrils of the same animal and the effect was the same. The difference in the blood flow response magnitude between saline and sodium nitrate was not significant. The power of the t- test is 0.17. Ruling out a Type II error with power=0.80 would require 29 animals in each group.
