Fig. 5.
Plasma (top) and lung tissue (bottom) nitrate and nitrite (NOx) levels at 2, 4, and 8 wk of age in sham-operated control and shunted lambs. Plasma and tissue NOx levels decreased from 2 to 8 wk of age in sham-operated control and shunted lambs (ANOVA). Plasma and tissue NOx levels were greater in shunted lambs than sham-operated controls at 2 wk. n = 5 for each group. Values are means ± SD. *P < 0.05 compared with age-matched sham-operated control; †P < 0.05 compared with 2-wk sham-operated control; §P < 0.05 compared with 2-wk shunt.
