Effects of hyperoxia on growth characteristics of metastatic murine tumors in the lung.


Suspensions of an oxygen-sensitive (MT-7) and of an oxygen-insensitive(M109) tumor cell line were injected i.v. into BALB/c mice. Exposure to 100% O2 after injection of the cells did not modify the initial arrest of either cell line in the lung. Exposure of animals given injections of MT-7 cells for 60 h to 100% oxygen decreased the number of lung colonies… (More)
