Table 6 Radial alveolar counts (RAC) at d37 and d52: RAC were significantly lower in Early Dex + Later CSO-treated and higher in Early Saline + Later RA-treated pups while Early Dex + Later RA animals were similar to controls. At d52, while RAC continued to be significantly lower in Early Dex + Later CSO-treated pups, Early Saline + Later RA effects were lost two weeks after stopping RA treatment. Values are expressed mean ± SE. *p < 0.01 vs. d37 Early Saline + Later CSO-treated animals; †p < 0.01 vs. Early Dex + Late CSO; ¶p < 0.01 vs. Early Saline + late RA. CSO: Cottonseed oil.
