Table 1. Mean arterial pressures and arteriolar diameters in 1K1C and 2K1C rats.

First Column: Mean arterial pressure in 1K1C rats (2 and 9 weeks post clipping) and 2K1C rats (4 weeks post clipping) versus mean arterial pressure in their respective sham-operated controls. The pressures represent averages of blood pressure measurements taken via the carotid artery in each anesthetized rat throughout the experimental protocol. Brackets indicate number of animals in each group * = p<0.05, mean arterial pressure significantly different from sham-operated controls. Third through Fifth Column: Diameter (µm) in cremasteric arterioles of 1K1C, 2 and 9 weeks post clipping, 2K1C, 4 weeks post clipping and in their respective sham-operated controls at rest (initial post-equilibration diameter) and before and after the application of DDMS with 0% oxygen in the superfusion solution (PSS). Vehicle alone had no effect on resting diameters (data not shown to improve clarity).
