FIG. 7.

Histology of lung tissue in infected mice treated with HMR 3004 (A), untreated infected mice (B), or healthy control mice (C). Pictures were taken 30 h after initiation of therapy, which corresponds to 78 h p.i. Diffuse edema with swelling of interstitium was noted in untreated infected animals, while HMR 3004-treated mice recovered very fast and had tissue profiles similar to those of healthy controls.
