“…Misonidazole under hypoxic conditions (less than 10 Parts/10(6) O2) shows the greatest toxicity. Split-dose experiments indicate that lethal damage can be "repaired" by O2, the magnitude of this repair being time dependent and a function of O2 concentration, with maximum repair in air seen after 2 h at 37 degree C. …”

“…Intraperitoneal inoculation of both mice and ferrets with swine influenza virus immunizes them to intranasal infection and it appears to make little or no difference whether the virus used as vaccine is obtained from the lungs of infected mice, ferrets, or swine. 5. Field experiments in which swine influenza followed the intramuscular administration of virus are cited as examples of the hazard involved in the use of this means of immunization in a densely crowded susceptible population.…”
