Abstract
DeMaria TF, Billy JM, Danahey DG. Growth factors during endotoxin-induced experimental otitis media.
The presence of growth factors in the middle ear fluid was examined during lipopolysaccharide-induced otitis media (OM) in the chinchilla. There was a progressive significant increase in the proliferative activity detected in the LPS-free MEF by five days in culture. We conclude that lps indirectly mediates hyperproliferative changes in the middle ear during OM by inducing growth factors.
