  • Values are means ± SD. L, left; R, right; %WT, percent wall thickness in arteries of 50- to 150-μm external diameter. Significant difference between left and right lungs in the banded animals:

  • * P < 0.01;

  • P < 0.05.

  • Significant difference between banded and sham-operated controls (P < 0.01).
