TABLE 1.

Relative Intensity and Cellular Sites of eNOS and nNOS Expression in Bronchial Tissue of Uninjured Sheep

NOS isoform Bronchial epithelium
Submucosal tissue
CC SC BC Endo MG MØ FB IF SM
eNOS + ++ ++ + + + – – +
nNOS – ++ – + + + – – +

Intensity of immunostaining (– = absent, + = light, ++ = moderate, + + + = strong) in CC = ciliated cells, SC = secretory cells, BC = basal cells, Endo = endothelial cells, MG = mucous gland acinar cells, MØ = macrophages, FB = fibroblasts, IF = inflammatory cells, SM = smooth muscle cells. Identical results were obtained in tissues from injured sheep.
