FIG. 4.
Septal thickness and inflammatory cell infiltration as a function of time between radiation and fungal exposures. Animals were exposed to radiation and fungal spores simultaneously or 8 weeks apart (8-week interval). Damage was then assessed at 1 and 4 weeks after the last treatment was given. For simultaneous exposures, significantly more damage was seen at 4 weeks than 1 week (#P < 0.05). Significantly less damage was seen at 4 weeks for the 8-week interval regimen compared with simultaneous exposures (‡P < 0.01).
